Foothill center offers vital grounds for cattle studies 
(Ag Alert) John Watson, May 22

During the summers of 2021 and 2022, as cattle roamed pastures and shaded woods of the University of California Sierra Foothill Research and Extension Center in Browns Valley, a UC Davis research team closely monitored potential ties between each animal’s personality and its grazing habits.

…“We have to bring the cattle in every 45 days and change pastures seasonally, which is more than we could ask of local cooperators,” said co-principal investigator Josh Davy, in a nod to the center’s ability to navigate constraints faced by commercial growers or landowners.

“The center’s staff members always create a positive working environment for collaboration and good solutions,” he added.


Cow methane emission reduction strategies expanding
(Brownfield Ag News) Nicole Heslip, May 22

An air-quality specialist says he expects strategies to reduce cattle methane emissions to greatly expand over the next five years.

Frank Mitloehner, a professor at the University of California-Davis, tells Brownfield carbon credits for capturing methane emissions from anaerobic digesters are helping farmers overcome cost barriers.

“In my opinion, within the next five years or so, it could happen that half of California’s dairy cows produce manure that ends up in a digester producing biogas, and as a result are receiving carbon credits.”

Woodland to host national agriculture robot conference in October
(ABC10) Devin Trubey, May 14

The future of farming in California includes artificial intelligence and robots to help farmers.

The International Forum of Agricultural Robotics and University of California system partnered to show farmers what’s possible at the Yolo County Fairgrounds, Tuesday.

Guests at the news conference saw self-driving carts that can move alongside workers to ease the burden of carrying crops to robots that can operate independently.

The hope is AI can solve the labor shortage for farmers while helping small family farms continue for generations.

“We are losing farmers. Who’s going to do the farming in the future? One of the things we have to do is help make farming more profitable and more sustainable for our farmers and their next generations, so they see a future there,” said Glenda Humiston, the vice president of UC Agriculture and Natural Resources.

The UC system hopes 50-60 new robots can be developed this year. They hold events like Tuesday’s to let farmers know they can get in on the ground floor and help design/create robots for their specific needs.

Commentary: Before wildfire season, take actions to protect farms
(Ag Alert) Tori Norville and Katie Low, May 8

Valley, Tubbs, Nuns, Atlas, River, Glass and August Complex. These are names of just some of the large wildfires that have impacted coastal and inland communities in Northern California since 2015.

In the past nine years, more than 2 million acres of forests, rangelands, chaparral and cropland burned from Sonoma, Napa, Humboldt and Trinity counties to multiple counties in the Sacramento Valley and Sierra Nevada.

Despite highly intense wildfire seasons in the past decade, the last two fire seasons were relatively calm. Slower fire seasons provide landowners the opportunity to improve their wildfire preparedness.


How race and education might be a factor in your grocery bill | (ABC 10 Dollars & Sense) Lora Painter, May 8

It might not come as a surprise Californians have the highest grocery bills in the country, averaging nearly $300 a week.

A new report from the U.S. Census shows race and education level might factor into how much you spend on food.

“There’s definitely different cultural elements that come into play,” said UC Davis Assistant Professor of Cooperative Extension & Community Economic Development Keith Taylor.


City Trees Save Lives
(Wired) Matt Simon, May 8

As urban populations are rising around the world, so are temperatures, putting ever more people in ever-hotter environments. “We’re primarily urban dwellers at this point,” says UCLA environmental researcher Edith de Guzman, coauthor of both studies and the cofounder and director of the Los Angeles Urban Cooling Collaborative. “We know that that’s problematic, because there’s a magnification of heat that occurs in those spaces, because of the preponderance of heat-retaining surfaces that then release that heat at night, when the body seeks to cool off.”

Dust from Dying Salton Sea Endangering Immigrant Communities Along its Shore
(Cronkite News – Times of San Diego) Jack Orleans, May 4

… The Salton Sea, California’s largest lake, is drying at a rate of 1.3 million acre feet per year. A study from the University of California, Agriculture and Natural Resources tracked the deterioration of the sea and surrounding ecosystem and determined that in addition to evaporation, a lot of water has been diverted to urban areas since 2018. Because of that, the salinity of the water and toxic materials in it have been concentrated in the dust, making it dangerous.


Invasive stinknet dominates natural areas and poses threat to native habitats
(Riverside Press-Enterprise) Michael Viramontes, May 3

To help control stinknet at home, we should familiarize ourselves with it and pull it out where we can. According to the University of California’s Integrated Pest Management Program the plants seeds mature within a few weeks of flowering. Dr. Chris McDonald, natural resource adviser for UC Cooperative Extension has studied control of the species. “For all invasive plants, the best advice is to bag them and put them in the trash. We don’t want the seeds to spread,” McDonald said, further recommending to double bag highly invasive plants, like stinknet, to avoid seed spreading if a bag tears.


Coyotes Seem More Aggressive? That’s Because They’re Feeding Their Pups. Here’s What You Need To Know
(LAist) Caitlin Hernandez, May 3

… Coyotes have three biological seasons, said Niamh Quinn, a human-wildlife interactions advisor with the University of California’s Agriculture and Natural Resources.

There’s breeding season, pup season, and then what she calls the dispersal season, where the young coyotes go off on their own. But during pup season, the coyotes are focused on raising and caring for the babies.

“They're starting to den down, and it’s been shown in certain areas that coyotes can be very aggressive around the den itself at that time,” Quinn said.

…If you’re curious where coyotes have been reported near you, check out locations below, updated with the University of California’s Coyote Cacher data as of April 24.


Hunger on campus: why US PhD students are fighting over food,

(Nature) Laurie Udesky, May 3

…A 2016 report about food insecurity at the ten campuses of the University of California (UC) system found that 25% of graduate students and 48% of undergraduates didn’t have enough to eat (see go.nature.com/49dedjx).

“We started producing the data to go to the state and say, we have a problem and we need to do something about it,” said Suzanna Martinez, a health-behaviour epidemiologist at UC San Francisco. Martinez led the research in her previous role at the university’s Nutrition Policy Institute in Oakland, California. “Since 2016, the UC system has published updates on food insecurity and actions to address it on its campuses,” she adds. These reports can be accessed online through the university’s Basic Needs Initiative (see go.nature.com/4begaus).


Bird flu is bad for poultry and cattle. Why it's not a dire threat for most of us — yet
(KFF) Amy Maxmen, May 2

The government should also help poultry farmers prevent H5N1 outbreaks since those kill many birds and pose a constant threat of spillover, said Maurice Pitesky, an avian disease specialist at the University of California-Davis.

Waterfowl like ducks and geese are the usual sources of outbreaks on poultry farms, and researchers can detect their proximity using remote sensing and other technologies. By zeroing in on zones of potential spillover, farmers can target their attention. That can mean routine surveillance to detect early signs of infections in poultry, using water cannons to shoo away migrating flocks, relocating farm animals, or temporarily ushering them into barns. “We should be spending on prevention,” Pitesky said.


Sustainable Control Tools for Vine Mealybug
(Wine Business) Kent Daane and David Haviland, May 1

VINE MEALYBUG, Planococcus ficus, is a serious pest of vineyards globally. The pest is believed to originate from the Mediterranean region of Europe, the Middle East and northern Africa-with invasive populations in the U.S. and Mexico likely to have come from Israel. Vine mealybug is one of at least eight invasive mealybug species that are pests in California vineyards and orchards, with only the grape mealybug, Pseudococcus maritimus, considered to be native to North America.

Expert describes devastating effects of bird flu as traces of virus are found in fifth of US milk
(Australian Independent) Katie Hawkinson, April 26

…With the rise in bird flu and its presence on six continents, the “worst case” for livestock is near, according to Maurice Pitesky, a specialist at the University of California, Davis, School of Veterinary Medicine.

“[The virus] has demonstrated an ability to move into dairy cows, and while it doesn't cause mortality it causes a decrease in milk production, which has economic impacts,” Mr Pitesky told The Independent. “This ultimately will affect the ability to produce fluid milk and all the things that are associated with it.”

How bird flu virus fragments get into milk sold in stores, and what the spread of H5N1 in cows means for the dairy industry and milk drinkers
(The Conversation) Noelia Silva del Rio, Richard V. Pereira, Robert B. Moeller, Terry W. Lehenbauer, Todd Cornish, April 25

The discovery of fragments of avian flu virus in milk sold in U.S. stores, including in about 20% of samples in initial testing across the country, suggests that the H5N1 virus may be more widespread in dairy cattle than previously realized.

The Food and Drug Administration, which announced the early results from its nationally representative sampling on April 25, 2024, was quick to stress that it believes the commercial milk supply is safe. The FDA said initial tests did not detect any live, infectious virus. However, highly pathogenic avian influenza virus can make cows sick, and the flu virus’s presence in herds in several states and new federal restrictions on the movement of dairy cows between states are putting economic pressure on farmers.

Five experts in infectious diseases in cattle from the University of California, Davis – Noelia Silva del RioTerry LehenbauerRichard PereiraRobert Moeller and Todd Cornish – explain what the test results mean, how bird flu can spread to cattle and the impact on the industry.


North Coast Viticulture Challenges and Resources for Climate Change Adaptation and Management
(Wine Business) Ted Rieger, April 23

…UC Cooperative Extension (UCCE) Napa County Viticulture Advisor Monica Cooper discussed local climate change trends that present challenges and vineyard adaptation practices that present opportunities for farming winegrapes in Napa Valley. In general, climate change challenges for specialty crops in California include: higher temperatures and reduced chill hours, increased frequency of climate and weather extremes, changing rainfall patterns, and changing pest and disease trends.

…UCCE Integrated Vineyard Systems Advisor Christopher Chen for Sonoma, Lake and Mendocino Counties listed several climate concerns with direct and indirect impacts on winegrapes and vineyards: 1. Change in growing season length. 2. Earlier or later budbreak and ripening. 3. More extreme weather events. 4. Resource scarcity (water, fertilizer). 5. Increased soil salinity.

Work is ongoing to breed and evaluate new cultivars to be available in the future to be better adapted to climate variables such as drought, heat and soil salinity. But as Chen pointed out, "Breeding new cultivars is a really slow process." He has been evaluating rootstocks that are already available for adaptive traits. "By identifying current rootstocks for specific site conditions, these can be useful in the shorter-term when growers replant vineyards," he said.


The Bird Flu Has Spread To Mammals – Will It Jump To Humans Next?
(LAist) Larry Mantle, April 23

For decades, public health experts have warned of the danger of H5N1, also known as the avian flu, crossing over to humans. That fear became a reality when earliest this month, a dairy farm worker in Texas tested positive for the highly pathogenic avian influenza. This is the first reported cow-to-human spread of the virus. The U.S. has only ever recorded a handful of cases but there is mounting concern that mutations in the virus will allow it to spread to more mammals and possibly, more people. Are we ready for an influenza pandemic of this kind? Joining us today on AirTalk to talk about this latest outbreak and the threat it poses to humans is Jennifer Nuzzo, Professor of Epidemiology and Director of the Pandemic Center at Brown University and Maurice Pitesky, Associate Professor in Poultry Health and Food Safety Epidemiology at UC Davis.


Parent Perceptions of School Meals Influence Student Participation in School Meal Programs
(Journal of Nutrition Education and Behavior podcast) April 15

A survey of 1,110 parents, guardians and caregivers led by Monica D. Zuercher, PhD, MS, Nutrition Policy Institute, University of California, found that more positive parental perceptions about school meals and their benefits to families were associated with greater student meal participation.

"Parent perceptions of school meals appear to influence student participation in school meal programs. Working to ensure parents are familiar with the healthfulness and quality of school meals and the efforts schools are making to provide high-quality, appealing meals may be critical for increasing school meal participation rates.”


Billions in tax credits for working families go unclaimed. How the IRS and state can fix this
(San Francisco Chronicle) Wendi Gosliner, Lia Fernald and Rita Hamad, April 10

“During the past three years, our research team spoke to hundreds of low-income Californians entitled to earned income tax credits to understand why they haven’t received them. One key problem is the lack of awareness. When asked, “What do you know about the EITC?” many responses were similar to one mother, who said, “Not much. Zero.” Another woman replied, “I know of it, but don’t really know, you know, the details of it.” 

We learned in our interviews that filing taxes was a barrier, involving complicated paperwork that took too much time and money to complete. One participant said, “Most people don’t know what they’re doing when they file taxes.” In fact, half the people we interviewed who filed taxes had paid $100 to $300 for tax preparation services even though they were eligible for free tax filing support.”


Arkansas led the nation sending letters home from school about obesity. Did it help?
(NPR) Kavitha Cardoza, April 9

…In what is considered the gold-standard study of BMI letters, published in 2020, researchers in California found that the letters home had no effect on students' weight. Hannah Thompson, a University of California-Berkeley assistant professor who co-authored the study, said most parents didn't even remember getting the letters. "It's such a tiny-touch behavioral intervention," she said.

… Hannah Thompson, the researcher from California, said that's the biggest problem with BMI letters: Parents don't know what to do with the information. Without support to help change behavior, she said, the letters don't do much.

"You find out your child is asthmatic, and you can get an inhaler, right?" she said. "You find out that your child is overweight and where do you even go from there? What do you do?"


Agriculture experts closely tracking economic impact of avian flu outbreak
(ABC7) Ahtra Elnashar, April 9

… “Replacing those type of birds takes time," said Dr. Maurice Pitesky, an associate specialist in cooperative extension at the University of California, Davis. “Not only are you losing birds that are producing eggs right now; you’re losing birds that were supposed to be producing eggs maybe in five, 10, 15 weeks.”

Pitesky said he expects egg prices to immediately be impacted, and it wouldn't be the first time. Last year, the flu helped push the price of eggs to a high of $4.82 per dozen in January, according to data compiled by the Federal Reserve Bank of St. Louis. By August, they dropped to $2.04.

Operating Costs Increase While Prices Decrease for Pistachios
(AgNetWest) Brian German, April 2

Operating costs for pistachio growers have been steadily increasing over the past few years, while average prices have been trending in the opposite direction. Assistant Professor in Cooperative Extension in the Department of Agricultural and Resource Economics at the University of California, Davis, Brittney Goodrich has been working on preliminary estimates to update the cost and return study from 2020. She said that costs have increased by about five percent on average since 2020.


9 Bugs That Look Like Bed Bugs
(Pest Gnome) Jane Purnell, April 1

Andrew Sutherland, UC Cooperative Extension integrated pest management advisor for the San Francisco Bay Area, answered a series of questions about bed bugs for Pest Gnome.

  1. How often have you experienced homeowners misidentifying bed bugs? What has proven (or can prove) to be the most significant consequence of misidentifying a bed bug?

Residents (I don’t use the word “homeowners” since many folks in my community don’t own their homes) sometimes misidentify other insects as bed bugs when bed bugs are suspected, especially if the insects occur near sleeping or resting areas indoors.

The most significant consequence of misidentification will be unnecessary pesticide application, which may lead to (unnecessary) pesticide exposure to people and pets.

Inside the Battle Over School Fitness Testing
(Outside Magazine) Erin Beresini, March 31

… But in recent years, scientists have found substantial evidence that children’s BMI is a poor predictor of future health—and even of current body fat, especially in children younger than nine. “Even in the ‘overweight’ category, it’s not necessarily predictive of poor metabolic health,” says Dr. Hannah Thompson, an animated Berkeley [and Nutrition Policy Institute] professor who explores how youth physical activity can improve health. “Cardiovascular fitness is.”


Legislative changes could transform California into a rodent haven
(Downey Patriot) Renee Pinel, March 27

… In the agricultural sector, roof rats can run rampant in California orchards, according to UC Agriculture and Natural Resources scientists. “In pistachio and other nut orchards, roof rats are burrowing and nesting in the ground where they’re chewing on irrigation lines, causing extensive damage,” said Rachael Long, UC Cooperative Extension advisor. And it’s not just the fruit damage. They nest in citrus trees, feeding on the fruit and terrifying field workers when they jump out as people are picking the fruit. The chewing pests are also girdling tree limbs, causing branch dieback.” 


It’s coyote pup season. Here are some precautions for pet owners
(LA Times) Karen Garcia, March 21

…Coyote pupping season stretches from the time when coyotes give birth to when the pups become juveniles and leave their parents, said Niamh Quinn, human-wildlife interactions advisor for the University of California Agriculture and Natural Resources. The average litter is between five and six pups.

Once the pups are born they tend to emerge from the den three weeks later, Quinn said.

“Pups will stay with their parents for about six months, spring to summer, and will be taught how to hunt and behave in their environment by their parents,” Quinn said. “In the fall, which is when food becomes scarce, the parents will consider keeping their juveniles or have them disperse to be on their own.”


Why the spread of organic farms may prompt growers to use more pesticide, not less
(LA Times) Karen Kaplan, March 21

...If destructive critters migrate from an organic farm to a conventional one, a grower may respond by using more pesticide. That, in turn, would undermine the helpful creatures organic growers rely upon. On the other hand, organic farms nurture beneficial insects that migrate to other fields.

“Organic farms can be both a blessing and a curse if they’re your neighbor,” said David Haviland, an entomologist with the University of California’s integrative pest management program in Bakersfield, who was not involved in the study....

...Milt McGiffen, a cooperative extension specialist with the Department of Botany and Plant Sciences at UC Riverside...said growers make a point of planting organic crops in places where they know pest control won’t be a big problem since they can’t use conventional pesticides.

“Mostly why you have have a group of organic farms together is because that’s where you have the fewest pests, not the other way around,” said McGiffen, who wasn’t involved in the study.


Parasitic weeds threaten tomato plants on California farms
(Daily Democrat) March 20

 “Most of the damage occurs before you can see it,” said Brad Hanson, a professor of Cooperative Extension in plant sciences, who is involved in much of the Orobanche research at UC Davis. “There’s a lot of ripples to the problem. We could see it spread to other crops and other regions in the state if it’s not managed.”

… At that same plot, Ph.D. student Mohammadreza Narimani and others from the Digital Agriculture Laboratory, which is run by associate professor of Cooperative Extension Alireza Pourezza, use drones equipped with special cameras and technology to scan the field.


Ascochyta Blight Discovered in Central Valley Garbanzo Beans
(AgNet West) Brian German, March 18

The presence of Ascochyta blight was confirmed in garbanzo bean fields in the Central Valley last month. Agronomy and Nutrient Management Advisor, Nick Clark said the discovery was made in the Five Points and Lemoore areas. While the disease has the potential to cause economic damage for growers, there are mitigation approaches available.

“We have azoxystrobin, boscalid, and pyraclostrobin that are registered for use in California garbanzos to control infection of Ascochyta leaf blight,” Clark explained. “Using foliar fungicides to control Ascochyta leaf blight doesn’t roll back the clock on infection and disease that’s already happened. It only works to help prevent new infection and new development of disease.”


This state program offers assistance with your water bill
(ABC10) Lora Painter, March 13

“With energy costs going up, your water bill is going to go up as well,” said Keith Taylor, UC Davis professor of cooperative extension and community economic development.

It’s why there’s a state program to help called the Low-Income Household Water Assistance Program. It’s federally funded and offers one-time support to help low-income households pay past due or current water and sewage bills to keep their water on.

“The impact is huge," said Taylor. "It keeps them from going into debt. It keeps them from having bad credit, and it allows them to get the basics...paying for their rent, paying for medication, paying for their food."


Growing Shade Equity, One Tree at a Time
(The Equation) Edith de Guzman, March 13

Beneath the reputation of Los Angeles as a land of cars, palms, and sunshine lies a reality of stark inequalities—including access to trees and shade. Nearly 20% of L.A.’s urban forest is concentrated where only 1% of the city’s population lives, endangering lower-income communities and people of color with hotter-feeling summers and poor environmental quality. In the US and elsewhere, heat is the biggest weather-related killer, and people who live with less shade are two to three times more likely to suffer from heat-related illness and death.


Spotted Lanternfly now present in 18 states
(Wine Business) Kerana Tdorov, March 11

The spotted lanternfly is now present in 18 states, said Cindy Kron, North Coast IPM advisor at UC Agriculture and Natural Resources. Originally from China, the spotted lanternfly was first discovered in 2014 in Pennsylvania, where it is commonly found in backyards. 

Kron spoke last week during a virtual panel on the insect organized by UC Davis’ Viticulture and Enology Department.

So far, no live adult spotted lantern fly has been found in California, according to state officials.

Entomologists study enemies of your enemy
(Good Fruit) Matt Milkovich, March 7

...There are parasitoids and other biological controls native to North America, but none evolved to successfully prey on SWD. Other fruit flies feed on soft, rotting fruit, but spotted wing drosophila feeds on ripening fruit with intact skin. SWD’s native enemies in Asia evolved to lay eggs in ripening fruit, allowing them to successfully parasitize SWD larvae, said Kent Daane, a cooperative extension specialist with the University of California, Berkeley. 

Daane has studied SWD since it first appeared in North America nearly two decades ago. He was a member of the research teams that visited China, South Korea and Japan seeking SWD’s natural enemies. They found several candidates and brought them back to quarantine facilities in the United States. The samba and ronin wasps rose to the top as potential parasitoids and appeared to work even better in tandem.

How You Can Help Refill LA's Aquifers By Capturing Stormwater At Home
(LAist) Jacob Margolis, March 4

It's tough to quantify how much any one yard will contribute to an aquifer, but according to analysis done for LADWP's Stormwater Capture Master Plan released in 2015, if widely implemented, water catchment features could have an impact.

"Parcel by parcel there is an additive effect and we've shown qualitatively that additive effect is really significant," said Edith de Guzman, water equity and adaptation policy cooperative extension specialist at UCLA.

The master plan was prepared with Tree People, which de Guzman was with at the time.

It depends on how you slice it, but according to de Guzman, if you add together all the small distributed projects possible (swales, rain gardens, permeable pavement) on everything from commercial properties to those with single family homes, we could theoretically add an additional 110,000 acres of land to our water percolation portfolio.


Beyond Beauty: The crucial role of almonds to the Valley’s multibillion-dollar agricultural economy
(Merced Focus) Christian De Jesus Betancourt, March 2

…The short-lived blooming window – usually about three weeks around February and March – is crucial to an industry where millions of bees are brought to the Central Valley to help cross-pollinate the crops that will be ready for harvest in August, said UC Cooperative Extension Orchard Crop Farm Advisor Cameron Zuber.

…“In Merced County, 20 to 25% of the almond growers are new to growing almonds,” said Zuber. “That doesn’t mean they’re new to agriculture. They might have grown other things or done other stuff prior.”

Storm barrels down on Sierra as blizzard conditions close Tahoe resorts
(KQED) Ezra David Romero, March 1

Susie Kocher lives in South Lake Tahoe in the unincorporated Meyers neighborhood, where the storm has dropped a foot of snow in the past 24 hours. As a forestry advisor for the University of California Cooperative Extension, she is working from home. She said as much as 8 feet of snow could fall on her area through Sunday.

“This lines up with the idea of a miracle March, where you haven’t had a whole lot of snow, but then all of a sudden, you get a dump, and now you have plenty of snow and water for the rest of California to use,” she said.

Compared to last year, where storm after storm piled snow on the region, Kocher said snowstorms this year have been much more manageable. They’ve sometimes produced  less snow than what meteorologists forecast. This storm, which the National Weather Service has said will be the most extreme in several years, could be different. When she went to the store Thursday night, much of the groceries and other necessities were all but gone.

"We don’t know how this came and when actually because the extent of the damage we are seeing in 2023 doesn’t seem like it’s just from that year," said Rijal.

They do know the beetle wreaked havoc on almond farms in Australia for the last decade.

"Anywhere from 2% to 5% damage they can see in most of the orchards, in almonds," said Rijal.


Poised to be first widely consumed gene-edited animals, virus-resistant pigs trot toward market
(Science) Jon Cohen, Feb. 23

…Alison Van Eenennaam, an animal geneticist at the University of California, Davis, is cheering the news. “There’s no point having a pig getting sick and dying if there’s an approach to genetically prevent it from doing so,” she says, adding that this benefits farmers, the pigs, and, ultimately, the consumer.

But Van Eenennaam laments the regulatory hoops the company is having to jump through. FDA views the DNA change made by the genome editor CRISPR as an “investigational new drug” that requires multiple submissions from Genus to establish the altered gene’s safety, ability to be inherited, and stability over generations, as well as the resulting pigs’ resistance to the virus. “You’re talking about a very, very expensive regulatory pathway,” she says, arguing it is unnecessary because unlike genetically modified organisms, to which DNA from other species has been added, the gene editing involved the pigs’ own DNA, creating changes that could happen naturally.


Invasive beetles threaten California almond crop: "One thing we know about this bug is we don't know anything"
(CBS13) Tori Apodaca, Feb. 22

… University of California researcher Jhalendra Rijal said that they do not know how the beetles got here, but they have been attacking almonds in Australia for the past ten years.

"If you get 1% statewide damage, which is 2 billion pounds, still, we're talking about millions of dollars lost every year," Rijal said.


Almond bloom looks good, so far, as industry outlook brightens
(Bakersfield Californian) John Cox, Feb. 21

Mohammad Yaghmour, a local orchard adviser with the University of California Cooperative Extension, said he has received reports that the bloom is going well locally but that he remains vigilant about fungi such as brown rot, which destroys almond blossoms, fertilized or not. He noted the disease was a problem last year.

Some orchards and certain almond varieties are more susceptible to fungi than others, Yaghmour said. He noted that growers are able to protect their trees using fungicides, but that if disease takes hold, there's relatively little to be done.

"That's why we have to protect the bloom rather than just wait for the problem to happen and then try to manage it," he said.


U.S. pistachio industry faces mixed news
(Farm Press) Todd Fitchette, Feb. 20

…Brittney Goodrich, an Extension specialist in agricultural and resource economics with the University of California, warned growers at a meeting in mid-January that as global supplies continue to outpace demand. She said this could compound grower returns as the cost of production continues to rise.

Katherine Jarvis-Shean, an orchard systems advisor with the UC Ag and Natural Resources, cautioned farmers at the same meeting to consider promoting profitability practices over pure production gains to remain globally competitive.


How to know if the olive oil you’re buying is actually good for you
(CNN) Kristen Rogers, Feb. 19

…Just like the compounds in tea or chocolate, those in olive oil degrade with time, especially if it’s stored in a hot environment or exposed to light or air, said Dr. Selina Wang, an associate professor of cooperative extension in small-scale fruit and vegetable processing at the University of California, Davis.



PRRS virus-resistant nucleus herd ready for breeding upon regulatory approval
(National Hog Farmer) Ann Hess, Feb. 19

CRISPR is king. That’s what Cooperative Extension Professor in Animal Genomics and Biotechnology at UC Davis, Alison Van Eenennaam, and her post-doc, Alba Ledesma, found out when the European Food Safety Authority asked them to do a review of the global research in genome editing of livestock for food and agricultural production.

“About 80% of all of the edits detailed in peer-reviewed research publications were being done using the CRISPR/Cas9 system. Other editing technologies such as zinc-finger nucleases and TALENs, predated CRISPR/Cas9, and comparatively they're more complicated and expensive to use. They do the same thing, make a double-stranded break in the DNA at a targeted location in the genome, but they're more expensive and complicated to use,” Van Eenennaam says. “That's part of the attractiveness and the democratization of genome editing is that with CRISR/Cas9, you just need to order a different CRISPR guide and you can target the Cas9 to cut at a different region in the genome.”


As organic sector thrives, research seeks to catch up
(Valley Voice) Bob Johnson, Feb. 16

…“Soil health, water and pest management are at the top in our preliminary survey of growers,” said Shriya Rangarajan, postdoctoral researcher at the UC Organic Agriculture Institute.

Rangarajan said many organic farmers have relied on getting information from other growers because of a lack of organic farm advisors and research.

The institute is attempting to coordinate the sources of information about organic agriculture scattered throughout the UC and Cooperative Extension systems and identify the most important knowledge gaps.


Will Southern California be the ‘Napa Valley of coffee’?
(LA Times) Julie Wolfson, Feb. 15

…It took Ruskey several attempts from the first planting of coffee trees in 2002 to learn best practices for growing coffee in Southern California. While tropical climates average above 60 degrees year-round and have generally high precipitation, he and other California coffee farmers are focusing on working with weather patterns, multilayer farming with other crops and careful use of water.

“I have always been passionate about crop adaptation,” says Ruskey. “I was working with the UC Cooperative Extension Service to plant lychee and longans when Dr. Mark Gaskell, a small berry crop expert, gave me 40 coffee plants and encouraged me to try planting them side by side with other plants.”


Turkestan Cockroaches with Dr. Andrew Sutherland

Hello bug lovers and welcome to a roach filled Valentine's edition of Artho-Pod! Jody and Jonathan meet up with Dr. Andrew Sutherland of University of California Extension. Andrew is an urban entomologist and an area IPM advisor for UC who serves the San Francisco area. As for today's topic, the Turkestan cockroach is an intriguing invasive species that is competing with other roaches, such as the oriental roach, for space. Due to a variety of factors, the Turkestan roach seems to be spreading and is also being noticed by people in the western US. All of that adds up to an interesting podcast episode filled with cockroach facts, thoughts on how the Turkestan roach is spreading, and possible management strategies. 


CRISPRed Pigs: Precision Porcine Gene Editing Combats PPRS Virus Threat
(Genetic Engineering & Biotechnology News) Uduak Thomas, Feb. 14

…“They were able to generate in a couple of generations a founder population of breeding boars (10–15 per line) and gilts to serve as a gene edited nucleus herd for ultimate commercial pork production and sale using classical breeding,” said Alison Van Eenennaam, PhD, an extension specialist in animal genomics and biotechnology in the department of animal science at the University of California, Davis. “There are more sophisticated approaches to guarantee the edited allele is in a homozygous state and absent off-target indels in all animals produced, e.g., using  edited porcine embryonic stem cells, but at the end of the day the approach they used did the job.”


The recent avian flu surge is affecting poultry farmers across the U.S.
(NPR) Leila Fadel, Steve Inskeep, Feb. 12

An avian flu outbreak that started in 2022 is still spreading.

MAURICE PITESKY: This outbreak is larger geographically. It's on six continents at this point.

FADEL: Dr. Maurice Pitesky is an associate professor at UC Davis School of Veterinary Medicine. He says the current surge in cases is decimating poultry farms across the country.

PITESKY: It's highly pathogenic, so unfortunately one of the more common symptoms is just mortality or death.


How California’s storms are projected to become more extreme with climate change
(LA Times) Ian James, Feb. 8

“The infrastructure that by and large we have today, it really wasn’t built for 21st century conditions. It was built during the 20th century, during a time when the extremes were less extreme,” said Edith de Guzman, a cooperative extension researcher at UCLA who focuses on water equity and adaptation policy. “We need to catch up with the changes and unfortunately, our flood management isn’t changing as quickly as our flood risk is changing.”

Research examining flood risks nationally has found that communities behind levees are disproportionately poorer and people of color.


California’s trees are dying in huge numbers — and Tahoe is the epicenter
(SF Chronicle) Kurtis Alexander, Feb. 8

...there’s the warming climate, which is intensifying droughts and making water even scarcer.

“You just have more trees than the rainfall we get on average,” said Bill Stewart, emeritus forestry specialist at UC Berkeley, who is not affiliated with the Forest Service mortality survey. “All the trees are getting stressed and the weaker trees are dying.”

In healthier times, only a few million trees, or less, might die in a typical year, according to the Forest Service. By contrast, the death count soared to a recent-high of 62 million in 2016.

The ramifications of forest decline are substantial. It can disrupt biodiversity, carbon storage and the towns and trades that rely on forest products. Dead and dying trees can also increase the risk of wildfire.

“It’s just all hot fuel,” said Stewart. “When you get a high wind event at a fire, now the fire just doesn’t stop. You’re getting these fires that change the forest for a century.”


Wet weather raising risks for local almond orchards
(Bakersfield Californian) John Cox, Feb. 5

Some almond cultivars are more susceptible than others to P. syringae, said Florent Trouillas, a fruit and nut pathologist specialist with the University of California Cooperative Extension.

"Nonpareils seem to be highly susceptible," he said, referring to one of Kern's most popular almond cultivars.

Treatment is done through the introduction of phosphates during irrigation. But Trouillas said that there's little sense trying to do anything about it as late in the year as May, because the disease dies when heat sets in by about June. He noted that any infections caused by this week's rains wouldn't become apparent until March.


UC Davis professor looking how to make table olive industry more economically feasible
(CBS Sacramento) Rachel Wulff, Feb. 2

Dennis Burreson has been growing table olives for 40 years.

"We used to enjoy a significant amount of the institutional marketplace. The pizza trade but we've lost 90% of it," Burreson said.

He says labor costs him half of his total revenue. It's one of the reasons production statewide is down from 37,000 acres when he started to just above 12,000 now. UC Davis professor Louise Ferguson has spent her career studying why.

"The table olive industry is hand harvesting and hand pruning costs," Ferguson said.


Entrepreneur spearheads proposal for nonprofit marketplace
(Morgan Hill Life) Calvin Nuttall, Feb. 2

… A big fan of the innovative project is Julie Morris. She serves as the Santa Clara County Agricultural Liaison at the University of California Cooperative Extension, working in collaboration with the county to implement its Agricultural Plan.

“What Joe and Lisa have proposed for this site is a perfect blending of supporting small farms and preserving ag land,” she said. “Because this is working agricultural land, we are going to need to work together with the county to create other uses, such as the event space and cafe or a restaurant. I hope that this will be a model for other places that want to support small farms and provide access to fresh, local food.”


Bird flu roils poultry industry, raising concern over egg prices ahead of Easter
(Food Dive) Nathan Owens, Feb. 2

… In the winter months, millions of waterfowl migrate to California for its warmer climate, said Maurice Pitesky, an associate professor at the University of California, Davis School of Veterinary Medicine. The proliferation of backyard flocks near commercial operations also “can be a recipe for disaster” once waterfowl get in the mix, he said.

“Wildlife are good at interfacing in all kinds of ways,” Pitesky said

… “If we keep dealing with this every year from an economic and animal welfare standpoint, we might have to pivot from poultry,” Pitesky said. “We consume 100 pounds of chicken every year —  It hasn’t always been that way.”

(Capital Press) Brad Carlson, Jan. 31

… Driven by avian influenza, egg prices hit record highs in 2022 and into January 2023 before returning to normal in early 2023, although “they probably overshot on the downside, and have come back to what’s essentially normal prices,” said Dan Sumner, distinguished professor in the University of California-Davis Department of Agricultural and Resource Economics and director of the UC Agricultural Issues Center.


What Nut Growers Should Know About the Carpophilus Beetle
(Growing Produce) David Eddy, Jan. 30

The latest pest to hit the Golden State is Carpophilus truncatus, more commonly known as the Carpophilus beetle. It doesn’t appear to be a threat in most of the rest of the country because only nuts have been attacked, so far. To date, almond and pistachio orchards infested by Carpophilus beetle have been confirmed in numerous San Joaquin Valley locations, suggesting that the establishment of this new pest is already widespread, according to Jhalendra Rijal, University of California Cooperative Extension IPM Advisor. In fact, some specimens from Merced County were from collections made in 2022 suggesting the pest has been present in the San Joaquin Valley for at least a year already.

“It has likely been here for a few years based on the damage we’ve seen,” Rijal says.

Burning Questions: Understanding Fire Management with Lenya Quinn-Davidson
(Nature’s Archive) Michael Hawk, Jan. 29

In today’s episode, we reconcile how it was possible for more acres of land to burn every year, but with less dramatic impact. In fact, that historical fire was largely beneficial to the land.

Our guest today, who helps us decipher historical fire and how we can add more beneficial fire back to the landscape is Lenya Quinn-Davidson.

And when you have a guest who’s first name literally means “firewood” in Spanish (alternative spelling), you know you’ve found the right person to discuss wildfire management. 


The greatest trees of Los Angeles
(LA Times) Ryan Bradley, Jan. 29

Donald R. Hodel is the Emeritus Environmental Horticulturist for the University of California, Cooperative Extension in Los Angeles. In 1988, Hodel authored a book, published by the California Arboretum Foundation, titled “Exceptional Trees of Los Angeles.” It is exactly what its title describes: a book of very good — or, I’m sorry, exceptional L.A. trees. It is long out of print, but I found a copy, and was thumbing through it when we spoke....

...Hodel thought first of the many streets in L.A. lined by great, glorious tree plantings: the coral trees along San Vincente, the Canary Island date palms lining the entrance to Dodger Stadium, the gum myrtles on Kenilworth Avenue in Pasadena, and of course, in Altadena, the deodar cedars along Christmas Tree Lane (“a spectacular planting,” Hodel said). But when I explained that it was specimens I was after, I heard Hodel go silent a moment. He had his book out, too, and was flipping through it. “Some of these trees,” he said quietly, almost to himself, “I haven’t been back to them in 30 years, and they may not be there.”

The farm bill is caught up in gridlock … again
(Marketplace) Savannah Maher, Jan. 24

… The farm bill is supposed to be renewed every five years. But the current one was passed a few months after deadline, and the one before that — the 2014 bill — came two years late. 

So, does this thing ever show up on time? 

“Good question,” said Daniel Sumner with a chuckle. “You know, occasionally.”

Sumner, an agricultural economist at UC Davis, says right now is an especially tough time to negotiate this massive spending package. Congress has been tied up just trying to fund the government.

“So if you’ve got your wrinkle that you’d like to see changed, then it’s disappointing to see it not go forward,” he said.


California ranks high worldwide for rapidly depleted groundwater
(CalMatters) Rachel Becker, Jan. 24

The study provides a global database that backs up observations that have long worried water watchers. 

“The major contribution is to bring into much sharper focus this global problem of groundwater depletion and over-pumping,” said Graham Fogg, a professor emeritus of hydrogeology at UC Davis who was not involved with the research.

“With groundwater, if it’s left unmanaged and unregulated, it’s going to be abused in many, many cases. And if that abuse goes on long enough, some basins will be exhausted of water.”


Groundwater levels are falling worldwide — but there are solutions
(Grist) Jake Bittle, Jan. 24

While the case studies of recovery provide blueprints for other areas, climate change might make replicating them difficult, said Helen Dahlke, a professor of hydrology at the University of California, Davis. As the earth warms, precipitation totals in dry areas will fall, and the decline in rain might cancel out some of the positive effects of groundwater regulation. 

“The measures that they’re talking about would be that much more impactful if they were able to counterbalance the decline in precipitation,” she said. “You’re playing a game of, ‘how much is coming in, and how much is going out?’”

A trial is underway to recycle old almond trees instead of burning them
(Australian Broadcasting Corporation) Victorian Country Hour, Jan 21

…University of California farm advisor Brent Holtz says turning almond orchards into wood chips at the end of their life is standard practice in the United States. He says in California the wood chips used to be burned to produce electricity, but he developed a technique to use them as mulch.

“Since 2015, our electrical industries have been mandated to produce more solar and wind power and burning wood chips to produce electricity is like burning coal. And they’ve fallen out of favor so we needed an alternative to our orchard removal because we couldn’t burn in California because of our air quality restrictions. That’s kind of when the industry turned to me when the cogeneration plants started shutting down in California. To look for an alternative to cogeneration burning or orchard burning in the field.”

(If I Could Change One Thing) January 20

Wendi Gosliner [Nutrition Policy Institute’s director of food policy research and translation] works to improve population health and nutrition by eliminating health disparities and improving federal food programs. How did SNAP and WIC programs change during the COVID-19 pandemic? How do socioeconomic factors impact access to nutritious foods? What are common misperceptions about nutrition policy in the US? Find out, on this episode of If I Could Change One Thing, the Health Policy Podcast of San Diego State University.

Some key quotes:

On obesity as a target health outcome for interventions: “We are continuing to learn that [obesity] is really a symptom of something else. So, we are focusing on what's really about health, which is a healthy social environment for eating healthy, cultivating a healthy relationship with food, providing whole, healthy, real foods that we know provide nourishment, rather than heavily processed foods. Making sure that we have food systems—the physical part, the social part, all of it—that's health promoting and not negative and nor stigmatizing is the answer to having a pathway to truly cultivating the healthy outcomes that we're looking for.”

On school meals: “The place that kids go to meet their educational and other needs, also cultivates an opportunity to have an experience of being well-fed and in an environment that's healthy and productive and can teach all of us what a healthy eating pattern would look like…  providing that reliable, healthy, acceptable meal at school can have all kinds of educational and other beneficial health outcomes for kids.”

On food waste: “When we think about growing food, and all of the inputs that are needed to grow food—the energy, the water, the soil, the human labor, the money to harvest it and transport it— then it gets to us, we buy it, we store it, and then we often throw it away. The amount of resources that's wasted with each food item that is thrown away is immense. And then not only that, but food, when it's decomposing in landfills, creates methane, which is a greenhouse gas contributor all on its own. So, for so many reasons, having us throwing away a lot of food is incredibly costly.”

…“Black scale is location and time specific,” Kent M. Daane, an environmental science, policy and management specialist at the University of California – Berkeley, told Olive Oil Times.

“If you were in Bakersfield, there is enough summer heat that smaller stages of the pest die off because they can’t deal with the hot temperatures,” he added. “However, in places like Madero, Modesto and Corning, black scale survives and thrives in milder weather.”


Almond Update: Navel Orangeworm Challenges Took a Toll in 2023
(AgNet West) Brian German, Jan. 18

The almond industry endured a tough year for navel orangeworm challenges in 2023 for a variety of reasons. During The Almond Conference, UC Cooperative Extension Entomology and Pest Management Advisor, David Haviland explained some key factors that made 2023 an abnormal year for pest pressures. One critical aspect for effective management of navel orangeworm is a timely harvest. Haviland explained that ideally, growers can harvest nonpareils before the third flight begins and get the nuts fumigated before worms become adults. However, that was not the case in 2023 and many growers saw what happens when it is not a timely harvest.


California Chill Report: Navigating Changing Chill Patterns
(AgNet West) Jan. 18

Chill patterns have been shifting over the past 50 years as a result of a higher frequency of warmer winters. UC Cooperative Extension Orchard Systems Advisor, Kat Jarvis-Shean noted that “last year was a luxuriant chill year.” However, this year could be a marginal one for chill accumulation. To address problematic chill patterns, Jarvis-Shean has been researching dormancy-breaking materials like Dormex, seeking solutions for walnut growers.

“It wasn’t really high on people’s radar last year because we had so much chill,” Jarvis-Shean explained. “But as people are watching that chill counter and thinking about playing around with Dormex because it’s recently labeled, I would say that this is a good year to experiment on a small scale.”


Soil sensors, drip reduce water use in desert lettuce
(Ag Alert) Vicky Boyd, Jan. 17

…Two years into a three-year study, University of California Cooperative Extension Irrigation and Water Management Advisor Ali Montazar said the two technologies paired together show promise to significantly reduce water and nitrogen use. The actual savings depend on a number of factors, including lettuce variety, soil type, planting date, prior irrigation system, planting configuration and bed width.


Farm Flock Losses Climb as Avian Flu Outbreak Spreads
(Ag Alert) Ching Lee, Jan. 10

…Maurice Pitesky, a poultry specialist and expert in highly pathogenic avian influenza at the University of California, Davis, said vaccines are likely part of the solution, but they’re not a panacea. He said not allowing the AI vaccine for poultry appears to be more of a political decision than one based on science. “This is an example of where the science is ahead of the policy and economics,” he said.

With millions of waterfowl arriving in California each fall during migration season, Pitesky said it’s clear poultry farmers need to do more than what they’ve done for years. He said biosecurity methods alone—including fencing, foot baths, vehicle washes and employee training—have not been sufficient to keep out AI.

“The reality is, if you have high waterfowl abundance around your farm and there’s AI in those waterfowl, there’s just no way that that physical operational barrier is good enough to prevent exposure and infection,” he said. “We need to think outside the barn.”

Pitesky is trying to get more farmers to also use prediction tools such as the Waterfowl Alert Network, a software subscription service that gives daily notifications to producers when waterfowl are close to their farms. Having this information, he said, would allow farmers to be more strategic about their biosecurity.

He compared the tool to weather forecasting that tells farmers when a storm is coming. If farmers know where high numbers of waterfowl are roosting, for example, they could deploy water cannons or blasters or change the habitat around the farm to push birds away.


UC ANR: Fifty Years of Water Research Projects in California
(Sierra Sun Times)  Erik Christian Porse, Jan. 9

For decades, California has supported research to improve water resources management. Within our archives at the California Institute for Water Resources (CIWR), we have records of nearly 250 funded research projects going back fifty years. This led us to ask, how have water research topics in California changed over time?


Rising bird flu outbreaks threaten national poultry, egg supply again
(KTVH Helena, Montana) Jan. 8

…The recent spike in highly pathogenic avian influenza (HPAI) has led poultry providers to euthanize hundreds of thousands of chickens and ducks in Sonoma County, Marin County, and Merced County in California. Other states, including South Dakota, Minnesota, Wisconsin, Kansas, Arkansas, Ohio, and Pennsylvania, have also reported outbreaks.

UC Davis Professor Dr. Maurice Pitesky tells CBS News that these figures are worrying, and there's a potential for another rise in poultry and egg prices.

"This is, at some level, an existential issue for the commercial poultry industry," said Dr. Pitesky. "It's going to take some time for the industry to adapt to this new reality. But unfortunately, I think, we're in kind of a new world in the United States with respect to the risk."


Avian flu surges in Northern California, threatening national poultry, egg supplies
(The Hill) Sharon Udasin, Jan. 7

…“There’s economy of scale in commercial agriculture, including poultry,” Maurice Pitesky, an avian disease specialist at the University of California Davis (UC Davis) School of Veterinary Medicine, told The Hill.

“No pun intended — if you put your eggs all in one basket, the virus gets into a facility and then all the birds have to be euthanized, unfortunately,” Pitesky said.

As of midday Friday, about 10.62 million birds in 63 flocks nationwide had been affected by highly pathogenic avian influenza (HPAI) outbreaks over the past 30 days, according to the U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS).

Of these flocks, 37 were commercial and 26 were backyard, and a total of 3.8 million birds were concentrated in California.


In a remote corner of California, roaming dog packs leave a trail of blood and terror
(LA Times) Susanne Rust, Jan. 4

… Dan Macon, a sheep rancher in the Sierra foothills outside Auburn, said it’s a problem that spans the state and is growing as more people move into that urban-wildlife or urban-agricultural interface.

“I don’t worry too much about coyotes, lions or black bears, but I do worry about domestic dogs,” he said.

In 2011, four of his sheep were killed by a neighbor’s dogs. It was the most brutal killing he’d ever seen. The animals were torn to pieces in what he described as a cruel, terrifying and likely very painful death.


Spread of avian flu in North Bay could be disastrous for future of poultry farmers

Carpophilus beetle discoveries emphasize importance of winter sanitation
(AgNet West) Jan. 2

Houston Wilson, Associate Cooperative Extension specialist in the Department of Entomology at UC Riverside, emphasized the need for proper and thorough winter sanitation in nut orchards in the wake of the discovery of the invasive pest Carpophilus truncatus. The beetle, first discovered in Australia ten years ago, was identified in an almond orchard in Merced County in September 2023. The pest has subsequently been found in pistachio and almond orchards in Madera, Stanislaus, and Kings counties.

The carpophilus beetle can be identified by an oval-shaped cavity in the hull and the kernel “packed with a fine powdery mix of nutmeat and frass,” according to UC ANR researchers.


Bird flu infects Northern California’s historic poultry region, putting small farmers in peril
(Mercury News) Lisa Krieger, Jan. 1

…“The main reservoir of the virus are waterfowl — the ducks and geese that like the really rich habitat that California supplies,” said veterinarian Maurice Pitesky of the UC Davis School of Veterinary Medicine, who studies the spread of avian diseases. The federal government’s surveillance program has detected the virus in wild birds in 14 California counties this migratory season.

New research suggests that California’s shrinking wild spaces are forcing wild birds to congregate in dairy lagoons, irrigation canals and wastewater treatment ponds, he said. California has lost about 95% of its historic wetlands.

“We’re concentrating waterfowl onto smaller areas, which facilitates disease transmission,” said Pitesky. “This also puts those wild animals closer to our commercial poultry facilities. Potentially infected birds are right next to barns and ranches.”


December 2023

Beyond the bottle
(Comstock's Magazine) Russell Nichols, December issue

Based on data from infants born in 2020, about 25 percent of infants are breastfed exclusively through six months, according to the CDC. Barriers include a lack of clinical support, inadequate family paid leave that gives parents time with babies at home, and workplace policies that don’t provide time and space to feed and pump, says Jennifer T. Smilowitz, assistant professor of the cooperative extension in the Department of Nutrition at UC Davis. Still, the benefits of breast milk continue to lure researchers from various fields. The fact that it delivers a plethora of different molecules to nourish, protect and communicate information to a baby makes breast milk an “awe-inspiring bio-fluid,” says Smilowitz.


Cattlemen’s association dinner set for January 13
(Red Bluff Daily News) Jean Barton, Dec. 30

Josh Davy, UC Cooperative Extension, wrote about the history of the Winter Dinner in the December 29, 2004 edition of the Daily News.

“”It is no coincidence that cattlemen have been a stable part of Tehama County agriculture since at least 1837.  Tehama’s mild annual winter ranges in the foothills create a great opportunity to graze cattle.  Cattle are grazed on the foothill rangeland from fall’s first rains until spring, when the soils dry out.  This is complemented by the highly productive irrigated pastureland in the valley.

…UC Farm Smart’s Sensory Garden Days have been in operation at its Holtville location since mid-November, Farm Smart Coordinator and Community Education Specialist, Valeria Landeros, said.

“This garden has been in the works for the last two years,” Landeros said. “We collaborated with UC master gardeners to build up these front vegetable beds, but all the other planters have been a mix of volunteer work and us putting together the plants.”

“All these others planters are different plants that you would find throughout the California landscape,” she said.


California Chill Report: Solutions for Growers Facing Chill Shortages
(AgNet West) Dec. 27

UC Cooperative Extension Orchard Systems Advisor, Kat Jarvis-Shean has been working on solutions for growers dealing with chill shortages. Historically, discussions surrounding chill accumulation have often concluded with limited recourse for growers. However, research is showing that nut producers have some options available to them to help with a lack of chill hours.

“UC has been diligently engaged, and several chemical companies have endeavored to provide tools for walnut growers,” Jarvis-Shean noted. “Resources traditionally available to fruit cultivators but historically lacking for those involved in nut crop cultivation.”

Rules aimed at long-contaminated groundwater drive California farmers and residents to court
(Associated Press) Amy Taxin, Dec. 21

Michael Cahn, irrigation and water resource advisor for University of California, Cooperative Extension, said he’s been working with Central Coast farmers to reduce the nitrogen they leave behind. Strategies include rapid-testing soil before applying fertilizer, improving water management and planting cover crops, he said, but added the problem won’t be resolved quickly.

“The reality is the value of vegetables is so high and a lot of time it is just easer to put more fertilizer and water on than do careful management,” Cahn said. “We have a lot of contaminated groundwater to use so it will take a long time to clean up. People say this could be 50 years in the future.”


California’s push for labor laws can have negative consequences for workers
(CalMatters) Dan Walters, Dec. 20

…Recently, the University of California’s Cooperative Extension branch, which researches agricultural issues, released a study indicating that having a 40-hour work week has not been as beneficial to farmworkers as its sponsors promised.

Alexandra Hill, an assistant professor at UC Berkeley, concluded that many workers who had hoped for a cornucopia of overtime pay saw their incomes reduced when employers limited them to 40 hours a week. Her study found that many workers experienced reductions in the $100-$200 range each week because farmers could not automatically pass on overtime costs to their customers.

“It’s really important to think carefully about how we can best implement policies that really benefit the people that we’re trying to (help),” Hill told The Sacramento Bee.


California Chill Report: The Crucial Role of Winter Chill in Fruit and Nut Trees
(AgNet West) Dec. 20

Farmers are closely monitoring a key factor that plays a crucial role in the success of their orchards – winter chill accumulation. Winter chill is the cumulative exposure of deciduous trees, such as tree nuts and stone fruit, to cold temperatures during the dormant season. UC Cooperative Extension Orchard Systems Advisor, Kat Jarvis-Shean, said that inadequate chill can create a host of issues for growers.

“When trees don’t get enough winter chill accumulation, we see a straggled bloom in the springtime,” Jarvis-Shean said. “So, a longer window of time between when the first flowers open and the last flowers open, which can then cause problems down the road with straggled harvests, different sizes in your lot, that sort of thing.”


Overtime law intended to help California farmworkers. New study says it led to less money
(Sac Bee) Mathew Miranda, Dec. 18

… Early research by Alexandra E. Hill, an assistant professor of Cooperative Extension at UC Berkeley, indicates that the law has resulted in a negative financial impact for workers.

Hill said many farmworkers are not working overtime and their take-home pay has decreased as a result of employers reducing hours. The study estimates about 10% of workers earning $100 to $200 less on their weekly paychecks.

...“It’s really important to think carefully about how we can best implement policies that really benefit the people that we’re trying to (help),” said Hill.


Bird Flu Outbreak Hitting Sonoma County Poultry Producers Hard
(KQED) Juan Carlos Lara, Dec. 15

…Maurice Pitesky, a professor at the UC Davis School of Veterinary Medicine-Cooperative Extension, said the outbreak is akin to a global pandemic among poultry.

According to the USDA, over 4.6 million birds have been killed so far this year compared to the almost 58 million birds killed last year when the outbreak began. The disease has been found in dozens of countries across five continents, according to the World Health Organization.

“I think most people at this point view the virus as somewhat endemic in the waterfowl population,” Pitesky said. “As long as the virus infects the ducklings and goslings that these adults are hatching, we’re probably going to be in some kind of persistent cycle with this specific strain of influenza for a while.”


Opinion: Wildland-urban fire disasters aren’t actually a wildfire problem

(Proceedings of the National Academy of Sciences) David E. Calkin, Kimiko Barrett, Jack D. Cohen, Mark A. Finney, Stephen J. Pyne and Stephen L. Quarles, Dec. 13

… Society largely regards the wildfire problem as the destruction of human communities. Collectively, disaster fires, such as those mentioned here, have been lumped into a category of wildland–urban interface fires. These problem fires were defined as an issue of wildfires that involved houses. In reality, they are urban fires initiated by wildfires. That’s an important distinction—and one that has big repercussions for how we prepare for future fires. To date, these repercussions have not received enough attention.


California Chill Report: Understanding the Nuances of Cold Temperatures
(AgNetWest) Dec. 13

Cold temperatures are a critical part of crop development, with trees requiring a certain amount of cold during the dormant season. UC Cooperative Extension Orchard Systems Advisor, Kat Jarvis-Shean said counting the number of hours that temperatures are below 45 degrees Fahrenheit has historically been how chill accumulation has been tallied. However, there are limitations to that system of measurement.

“There are things about the California climate that make that a not great way for counting chill. The trees would sometimes react differently from how we would expect if we were just counting with chill hours,” Jarvis-Shean explained. “Any human body knows it feels different to be at 44 degrees than 33 degrees. The trees feel the same way, that those are different temperatures, different experiences.”


New Study Finds Farmworker Pay Actually Decreased Following Passage Of Law Ensuring Overtime Pay
(KQED) Tyche Hendricks, Dec. 13

A California law meant to ensure overtime pay for farmworkers may be leading growers to cut workers’ hours, and thus actually reduce their paychecks. That’s according to new research out of UC Berkeley. 

“I wanted to see did this law make workers better off. In the short run, the answer I’m finding is no.” said Alexandra Hill, UC Cooperative Extension agricultural economist at UC Berkeley. More research is needed on how to craft policies that protect workers’ rights without hurting their already low incomes.

New, old beetles add pest pressure on state orchards
(Ag Alert) Ching Lee, Dec. 6

… The carpophilus beetle is new to California and the U.S., but growers in Australia have been trying to manage infestations for nearly 10 years, said Jhalendra Rijal, UC integrated pest management advisor. The insect is concerning because the adults and larvae feed directly on the kernel, reducing quality and yield.

“They’re using that nutmeat as a food source,” Rijal said. “It’s a pretty serious issue in that regard.”

…Meanwhile, a different kind of beetle—the Pacific flatheaded borer—found attacking pear fruit in Lake County is “blowing entomologists’ minds,” said Clebson Gomes Goncalves, UC diversified farm advisor for Lake and Mendocino counties. That’s because the beetle is known as a wood-boring insect, with no previous record of it feeding on fruits.

“It’s confusing because they should be attacking the bark of the tree, not the fruit,” Goncalves said of the beetle.

UC researchers say climate change is causing more pests to target farms
(KVPR) Rachel Livinal, Dec. 5

…But just how exactly climate change affects pests, and, in turn, how it affects crops, has often been a topic of little research, says Tapan Pathak, the UC Cooperative Extension specialist in climate adaptation in agriculture based at UC Merced.

Pathak says more information can help farms be more resilient. The latest research will be used to update the “CalAgroClimate” database which he says “informs farmers on the progress of pests during the season.”

State expands quarantine to stop spread of invasive fruit fly in Thousand Oaks area
(Ventura County Star) Cheri Carlson, Dec. 5

… With 100-plus potential host plants, the fly is considered a major threat, said Hamutahl Cohen, an entomology advisor with UC Cooperative Extension in Ventura County.

“We are concerned because it is one of the most serious agricultural pests globally,” Cohen said. “We have seen it cause a lot of damage in other regions like in Australia.”

… People may not realize that fruit or vegetables from their yard are infested, Cohen said. It can take some time for the hard-to-spot eggs to hatch into maggots. The concern is that if they share fruit or vegetables, then a person outside the area may throw them away after finding them rotten inside.

“All of a sudden, there’s a fruit fly in their neighborhood as well,” she said.


Climate Change Is Threatening These Californian Fruits and Nuts—Study

…"These three pests are notorious for infesting most of the walnut, almond and peach orchards of California, causing extensive damages by reducing quality of fruits and nuts," study co-author Jhalendra Rijal, the UC Cooperative Extension integrated pest management adviser and entomologist for Stanislaus, San Joaquin and Merced counties, said in a press release detailing the findings.


Marin 4-H clubs merge into countywide organization
(Marin Independent Journal) Krissy Waite, Dec. 3

… Steven Worker, the 4-H youth development adviser for Marin, Sonoma and Napa counties, said the countywide club model was instituted in order to ease the learning curve for new families and reduce the administrative burden on the club leaders, who are often parents.

One way these barriers were reduced was through a gift from the Miranda Lux Foundation, a San Rafael nonprofit focused on vocational education. The $25,000 donation in September will allow the $75 annual enrollment fees to be waived for up to 300 youth members and 75 adult volunteers.

“This should help open it up to people and families who wouldn’t be able to participate otherwise,” Worker said.

Exotic fruit fly triggers California quarantine
(Valley Ag Voice) Natalie Willis, Dec. 1

Two Queensland fruit flies were detected near Thousand Oaks, leading to a first-of-its-kind quarantine in the United States, covering 90 square miles. According to Hamutahl Cohen, the University of California Cooperative Extension entomology advisor for Ventura County, the Queensland fruit fly is unique in its ability to withstand different temperatures and conditions, making it difficult to control.

She noted that along with the Queensland fruit fly quarantine, there are six other active fruit fly quarantines in California, including the Mediterranean fruit fly, the Oriental fruit fly — which spans three quarantines — and the Tau fly. Cohen explained that fruit flies generally share the same characteristics in affecting host plants.

“What they do is they lay their eggs under the skin of the fruit, and then the egg hatches into a larva or maggot, which travels throughout the fruit and introduces decay organisms like bacteria that facilitate rot,” Cohen said. “They all have the same life cycle and are hard to control once the populations take root.”


250,000 birds to be killed at 2 Petaluma poultry farms after avian flu detected
(The Press Democrat) Mary Callahan, Phil Barber and Colin Atagi, Dec. 1

… Maurice Pitesky, a faculty member at the UC Davis School of Veterinary Medicine who specializes in poultry health and food safety epidemiology, said a bioterrorism attack is not inconceivable.

“If I wanted to be an evil genius, and I found a dead duck in a park or some dead geese in a park, and I took that duck and I rubbed its fecal material all over my shoes, and then I went somewhere and tried to spread it — you know, sneaked onto a farm and then threw a shoe — yeah, certainly that's plausible,” he said.

But as Pitesky emphasized, it’s also entirely plausible that a wild bird introduced the virus to the Sonoma County farms.

“We’re in the thick of it,” he said. “This is avian influenza season. And even with the best of the best biosecurity, we're sometimes swinging and missing, and we’re getting positives.”

Federal Disaster Loans Available for Del Norte Businesses Following Smith River Complex Wildfires
(Wild Rivers Outpost) Jessica Cejnar Andrews, Nov. 30

…A product of the COVID-19 pandemic, the task force currently includes representatives from the Del Norte County Office of Emergency Services, Crescent City and the U.C. Cooperative Extension. The extension’s economic development advisor, Alec Dompka, was instrumental in creating the injury surveys and analyzing the data, Vosburg said.

“The injuries ranged from, on the low end, a vacation rental guy who said he lost $11,000 — that can be a lot of money to somebody — all the way up to almost $200,000 from another local business,” she said, adding that the business that lost $200,000 ships their product out of Del Norte County. “[The fires] caused them to have a lot of spoilage and waste.”

Businesses, including small agricultural cooperatives, those engaged in aquaculture and most private nonprofit organizations may qualify for Economic Injury Disaster Loans of up to $2 million, according to a SBA press release from Nov. 6.

City-based scientists get creative to tackle rural-research needs
(Nature) Virginia Gewin, Nov. 21

…Better yet, says Susana Matias, a researcher who sits at the nexus between UC Berkeley, the Agriculture and Natural Resources network and community members, is sharing the leadership and decision-making. When analysing data from the state’s largest farmworker population health surveys, for instance, Matias found increased risk of chronic health conditions, notably obesity, compared with elsewhere in the country.

For example, in one project, Matias and her team partnered with a berry grower, who allowed them to run a health-promotion programme focusing on diet and exercise with farmworkers in their fields in California5. Although the programme did not measurably improve health outcomes, the researchers think it was highly valuable in engaging the farmworker community. “Roughly half of these populations are potentially undocumented immigrants, so it is key to have community-based partners to help build trust and access,” says Matias, who emphasizes that placing value on community members’ time and expertise is an important way to build mutual respect and workforce capacity.

Sudden Oak Death lying low in Napa County
(Napa Valley Register) Bill Pramuk, Nov. 17

…The good news is all samples from Napa County tested negative this year. On the other hand, Dr. Garbelotto cautioned, the Napa Blitz was held before a period of late, warm rain. The pathogen, Phytophthora ramorum, is dependent on water and mild to warm temperatures so it may have been lying low in early April. Personally, judging by the dead coastal live oaks I have spotted along the creek by Broadmoor Drive and Redwood Road near Dry Creek Road, I think homeowners and property managers should be informed and should act where valued live oaks are at risk. Now, November to December, is the time to do the bark spray or trunk injection treatments.

Using CRISPR to breed bird flu-resistant chickens
OICanadian, Nov. 11

… Alison Van Eenennaam, an animal geneticist at the University of California, Davis, who was not involved in the study, said this suggests that editing the only gene targeted by the researchers is not a powerful enough method to make a difference.

The study’s researchers agree with Van Eenennaam that their next step is to breed chickens with all three genes edited. It will take decades to put the necessary technical and regulatory measures in place, but researchers say CRISPR gene editing will eventually save countless chicken lives and transform the livestock industry. “Chicken is the best,” Van Eenennaam said. “It’s great to use this technology to breed animals less susceptible to disease.”

Stanford researchers publish first paper to quantify how much protection we get from beneficial fires
(KQED) Danielle Venton, Nov. 10

New research published Friday from Stanford University and Columbia University points the way forward. In it, researchers quantify for the first time the magnitude of protection an area enjoys following a mild, beneficial fire — such as a prescribed fire — and how long that protection lasts.

The authors find that after an area has experienced low-intensity fire, the likelihood of a future high-intensity fire — the kind that grows out of control and takes out neighborhoods — is reduced by 64%. The protection lasts at least six years and then diminishes after that.

“It totally substantiates what we already see on the ground and what we already know to be true, which is that low- to moderate-severity fire begets more of the same,” said Lenya Quinn-Davidson, the director of the UC Ag and Natural Resources Fire Network.

It’s been 5 years since California’s deadliest wildfire. Can we stop it from happening again?
(LA Times) Hayley Smith and Alex Wigglesworth, Nov. 8

Data gleaned from that study and others have informed improvements to state rules and regulations that better address radiant heat, said Yana Valachovic, a forest advisor with the University of California Cooperative Extension and another of the study’s authors. For instance, a new law will soon require ember-resistant defensible space zones within 5 feet of a home. Those rules would have made a significant difference in the Camp fire, she said.

“We don’t fight earthquakes, tornadoes or hurricanes,” Valachovic said. “We adapt and build smarter. And Paradise really has given us strong information about what that adaptation needs to look like.”


As Extreme Heat Increases, Heart Attacks Will Rise
(Wired) Maryn McKenna, Nov. 1

… “One way we can explain those differences is by looking at the impact of historical drivers, for example, redlining,” says Edith de Guzman, a heat researcher and cooperative extension specialist at UCLA, referencing a 20th-century policy in which banks refused to sign mortgages in minority or poor neighborhoods. “Even years after the end of redlining, there are legacy impacts that are very obviously detectable in how hot neighborhoods get, even in the same city.”

… Work by de Guzman and others has shown that cities can be reconfigured to protect residents against extreme heat, by identifying zip codes that are most at risk and then installing reflective surfaces and planting trees. “We’re literally talking about changing land cover in cities,” she says. “We found we could reduce the number of deaths, depending on the heat wave and depending on the community, in the neighborhood of 25 to 50 percent.”


How two scorched giant sequoias kicked off a controversy about controlled burns in California
(LA Times) Alex Wigglesworth, Nov. 1

… In October, a team of experts hiked to the Orphans to examine them. Both had plenty of green in their crowns and had regrown foliage since the fire, said Kristen Shive, a fire ecologist and assistant professor at UC Berkeley who has studied how much crown damage giant sequoias can sustain.

“I saw two very happy living trees,” she said. “I expect both of them to survive.”

… “I think the key is we have to start thinking about these as dynamic ecosystems again, rather than as museum pieces, where we naively think we can keep every single one of them around forever,” Shive said.

Pregnant farmworkers in California are eligible for paid time off — but many don’t know it exists
(The 19th) Jessica Kutz, Oct. 31

For over two decades, a growing body of research has found several associations between pesticides and issues in early childhood development, specifically for children born in farmworking communities. 

What the research has found is that prenatal exposure to pesticides has been linked with neurodevelopmental issues like decreased cognition and lower IQ in childhood and an increase in ADHD and autism, said Carly Hyland, an epidemiologist at the University of California, Berkeley who has worked on a study of 600 pregnant farmworkers in California’s Salinas Valley, and has followed the development of their children since the 1990s.

Studies have also found some associations between pesticide exposure and adverse respiratory outcomes like asthma, she said.


California wildfire threatens 1,300 homes south-east of Los Angeles

…“If we get the wrong weather at the wrong time and that aligns with the really dry fuels – which we know we have way too many of – it could still end up being a really serious fire season,” Lenya Quinn-Davidson, fire network director for the University of California’s division of agriculture and natural resources, said last month.


Highland fire forced residents to flee. ‘I went outside and couldn’t breathe’
(LA Times) Priscella Vega, Hayley Smith and Alex Wigglesworth, Oct. 31 

...Santa Ana winds have driven many major fires in Southern California, said Luca Carmignani, a University of California Cooperative Extension wildfire advisor based at the UC South Coast Research and Extension Center in Irvine. The winds originate inland, gaining speed, warming up and drying out as they move from higher to lower elevations and squeeze through narrow canyons and passes.

Ignitions that occur without wind or dryness can usually be managed, but strong winds make it easy for flames to propagate to the rest of the vegetation.

“It’s like blowing on a barbecue — you invigorate the flames, you invigorate the combustion process so the fire can spread much, much better and faster,” Carmignani said.


Calif. tree nuts under attack by new beetle
(Western Farm Press) Todd Fitchette, Oct. 30

…This new beetle – Carpophilus truncatus (Nitidulidae) – is a known pest of almonds in Australia, where they have been dealing with infestations for almost a decade now. More recently there have been reports of similar Carpophilus beetles infesting walnuts in Argentina and Italy.

Now we can add California to that list. Beetle infestations were observed in almond and pistachio orchards earlier this fall, and specimens collected by the University of California Cooperative Extension were subsequently confirmed as Carpophilus truncatus by the California Department of Food and Agriculture, according to Houston Wilson, associate Cooperative Extension specialist in the Department of Entomology at the University of California, Riverside. So far, the presence of the beetle has been confirmed from orchards in Stanislaus, Merced, Madera, and Kings counties. Wilson and colleagues are now conducting a broader regional survey of orchards throughout the rest of the San Joaquin Valley.

…The insect may already be widespread, as the damage it causes has been seen for several years in the San Joaquin Valley, according to Jhalendra Rijal, entomologist and area integrated pest management advisor with the University of California Cooperative Extension in Stanislaus County. “It has likely been here for a few years based on the damage we’ve seen, but it may have been confused for another insect,” Rijal said.


San Francisco has fewer trees than most major cities. Residents are trying to fix that
(SF Chronicle) Tara Duggan, Oct. 29

“They grow to be large trees, and they need to be intensively pruned over time to develop good structure,” said Igor Lacan, a University of California Cooperative Extension adviser who specializes in urban forestry. “They look great in parks, but you can’t really envision having one as a street tree.”

When trees are planted, they need to be hand-watered for three years, and that labor accounts for $1,500 of the $2,000 cost per tree. If watering stops even for a few weeks during the dry season, the tree can be lost, Lacan said.

“In San Francisco, planting trees is challenging, but keeping those trees alive is much more challenging,” he said.

The state of California granted the university $80 million to commence 38 research projects, each directly addressing climate change, in August.

These projects will be a collaborative effort between academic researchers and community-based experts throughout the state. Many of the projects and researchers are affiliated with UC Berkeley, including Ted Grantham, campus associate professor of cooperative extension in the department of environmental science, policy and management.

“Our project is launching COEQWAL – the Collaboratory for Equity in Water Allocations,” Grantham said in an email. “The goal of our project: to democratize the information used in water and climate adaptation planning in California.”

What Does 'Unavoidable' West Antarctic Ice Shelf Melt Mean for the Bay Area?
(KQED) Ezra David Romero, Oct. 25

…UC Davis professor Mark Lubell said the study is like “a time machine” for the impacts of sea-level rise, even if it doesn’t have granular estimates for exactly how much sea-level rise the Bay Area can expect in the coming decades.

“We can’t predict the future perfectly, but this puts more weight into the likelihood of more severe rapid sea-level rise, which means that we need to think more seriously about adaptation in the Bay Area,” said Lubell, who studies governance and sea-level rise.


California wildlife officials test dead geese for avian flu found in Sacramento's Land Park
(CBS Sacramento) Tori Apodaca, Oct. 25

...Sandra Foreman with the Wildlife Care Association told CBS13 she is pretty positive we may have a bird flu breakout on our hands because of symptoms like cloudy eyes or wobbly heads plus the time of year it is. 

"We go from 600,000 waterfowl to over 6 million waterfowl over the next several months," said Dr. Maurice Pitesky, an associate professor at UC Davis College of Veterinary Medicine. 

Dr. Pitesky's research focuses on the application of epidemiology and disease surveillance to poultry health.

Since 2014, over 100 million commercial poultry have died from the disease. Last year, the Sacramento Zoo protected its birds because of nearby outbreaks. 


Varroa Mites Are a Honeybee’s 8-Legged Nightmare
(KQED) Gabriela Quiros, Oct. 24

Every year, up to half the honeybee colonies in the U.S. die. Varroa mites, the bees’ ghastly parasites, are one of the main culprits. After hitching a ride into a hive, a mite mom hides in a honeycomb cell, where she and her offspring feed on a growing bee. But beekeepers and scientists are helping honeybees fight back.

As California Gets Drier, Solar Panels Could Help Farms Save Water
(Civil Eats) Anna Guth, Oct. 4

…Ruth Dahlquist-Willard, the interim director of U.C. Sustainable Agriculture Research and Education Program (SAREP) who works with small farms in the Fresno area of the Central Valley, is watching the research. She supports exploring agrivoltaics on farms of all sizes in her region, but emphasized that pilots are needed so farmers can plan for altered crop yields under shade and obvious on-the-ground challenges, including that the panels can affect tractor access and irrigation systems and need regular maintenance.

… Agrivoltaics may also help conserve water. “The shade that is created by the solar panels, in areas that receive more sun than plants need for their photosynthesis, reduces the heat stress on those crops, makes them healthier, and makes them require less water,” [UC Davis professor Majdi] Abou Najm said. “Agrivoltaics is more than just a dual production of food and energy on the same plot of land—it maximizes the synergy between the two.”

Agrivoltaics stand to assist Central Valley farms in myriad ways, said Dahlquist-Willard. Larger farms that adopt agrivoltaics could potentially benefit smaller ones by alleviating pressure ­on regional groundwater. At the same time, farmers with less land are more likely to consider agrivoltaics than converting entirely to solar. “For a small farm—say 10, 20, 30 acres—if you convert your whole farm to solar, you’re quitting farming. Nobody does that when farming is their only source of income,” she said.


Farmers join study on curbing water use
(AgAlert) Christine Souza, Oct. 4

…This year, Biagioni received grant funds through the program to plant nonirrigated corn. He also agreed to host monitoring equipment for related research by Kosana Suvocarev, an assistant professor and cooperative extension specialist in biometeorology at UC Davis.

… Although this work is happening in 20 locations across the state, the site is one of six delta farms where Suvocarev and her team of students collect data to study various water conservation strategies affecting water budgets.

“We are measuring in very nontypical conditions to see how we can improve the management of crops to avoid unnecessary losses of water to the atmosphere,” Suvocarev said. “For the delta specifically, because it is such a vulnerable hydrological knot of California, we need to see how to keep that water in the ground” and prevent saltwater intrusion.

The Gamble: Can Genetically Modified Mosquitoes End Disease?
(New York Times) Stephanie Nolen, Sept. 29

… This team, working with a project called the University of California Malaria Initiative, has already successfully engineered the Anopheles coluzzii to block the parasite in a lab. And the scientists believe they can harness gene drive, a process in which an inherited trait spreads swiftly throughout a population, so that all the species’s offspring will carry it, not just half, which is the way inheritance normally works.

… Greg Lanzaro, a molecular geneticist at the University of California, Davis, who leads the malaria team, believes his group has that solution.

This Is Your Kid’s Brain on Extreme Heat
(Wired) Matt Simon, Pia Ceres, Sept. 15

… Park is referring to the increasingly severe phenomenon of urban areas getting way, way hotter than surrounding rural ones. Concrete and buildings soak up the sun’s energy by day and slowly release it at night, and cities lack vegetation that can “sweat” to cool the landscape. “Unfortunately, the case is that we see lower-income communities—which tend to be those that have a larger preponderance of impervious surfaces, buildings, and asphalt, and a lower cover of trees and other vegetation—those do tend to be the hotter ones,” says Edith de Guzman, who studies urban heat at the UCLA Luskin Center for Innovation. Schools are themselves little urban heat islands, with lots of densely packed buildings surrounded by impermeable surfaces like basketball or tennis courts, parking lots, and courtyards.

A climate scientist wanted to start a debate in academia. He set off a bigger firestorm
(LA Times) Alex Wigglesworth, Sept. 12

Days after publishing research that found global warming had boosted the risk of fast-growing California wildfires by 25%, scientist and lead author Patrick T. Brown announced that he’d withheld the full truth to maximize the article’s chances of being published in the journal Nature....

...Max Moritz, Cooperative Extension wildfire specialist at UC Santa Barbara, said he doesn’t think it’s a frequent occurrence that scientists intentionally simplify their work or omit data for the sake of appearing in high-profile publications. Simplified studies and models more often result from data limitations, and short-form, high-impact journals tend to leave little room for much discussion of these limitations, caveats and complexities, said Moritz.

But it’s true that studies with nuanced findings and messy policy ramifications make for more challenging stories to tell, which may make them less likely to be picked up by high-profile journals and media outlets, he said.

“So as scientists, we often are faced with that trade-off: Can you simplify the messaging about a complex study just so we can get the important message out about the most salient and actionable points?” he said. “Those are some of the decisions that I think are challenging as a researcher.”

He calls the restored tidal marsh “a living laboratory,” “a big, fancy petri dish.”

…The reason these tidal wetlands are so productive, in part, is because of their long growing season, he said.

“We have plenty of water, plenty of sunshine, so really tall, dense vegetation can grow, and so that’s really good at capturing light for photosynthesis,” he said.

You can grow healthier, happier vegetables and herbs by companion planting—here’s how
(Well+Good) Helen Carefoot, Sept. 4

The tradition has its roots in several cultural traditions from Native American nations, particularly the Iroquois and Cherokee nations, of planting "the three sisters," or corn, squash, and a climbing bean together. “The idea is that the corn provides some of the initial structural support for the beans, then those two combined provide not only shelter but nitrogen-fixing and nutrients in the soil, then the winter squash is getting some shade and nutrients from those earlier crops while it flourishes in the fall," explains Scott Oneto, farm advisor at University of California Cooperative Extension.... 

...Creating a garden with as much biodiversity as possible—which is what happens with companion planting—helps avoid the issues of a monoculture, which are more prone to be felled by pests and plant illnesses, says Cynthia Nations, PhD, a retired education consultant and a UC Master Gardener in San Mateo/San Francisco Counties in California.

We Can Reduce Warming – Frank Mitloehner
(Farm To Table Talk podcast) Rodger Wasson, Sept. 1

Reducing methane reduces warming. Methane is nothing more than energy that instead of off-gassing into the atmosphere can be captured to use for transportation and other benefits–converting a liability into a utility.  Livestock, not only cattle, contribute to methane off-gassing now but less in the future when as a result temperatures will be go down. Technologies and new research are providing the new solutions ranging from methane digesters on farm manure holding lagoons and non-gmo genetics to breed low methane animals. At the center of these developments is Clear Center at UC Davis, under the direction of Dr. Frank Mitloehner who joins Farm To Table Talk to shares the learned facts and  promise of better climate future.  www.clear.uc.davis.edu

Climate change makes wildfires in California more explosive
(NPR) Alejandra Borunda, Aug. 30

… As much influence as a heated-up atmosphere can have, it's far from the only factor at play. "Explosive growth of fires is almost always in some way correlated with high winds," which whips small fires into enormous ones, points out Max Moritz, a fire expert at the University of California, Santa Barbara, who wasn't involved in the study.


Move over Hass — there's a new, more sustainable avocado in town
(KJZZ) Lauren Gilger, Richard Copeland, Aug. 29

… Mary Lu Arpaia is a horticultural specialist with UC Riverside’s cooperative extension and she’s one of the inventors of this new Luna variety of avocado. Her name is on the pending patent, and The Show spoke with her more about it.

And how does it taste? “The Luna, I would say it’s not quite as nutty as a Hass,” Arpaia said. “But it has, to me, almost a floral characteristic to its flavor. It sometimes can be a little bit sweet. And instead of being super creamy — it is creamy — I would say that its texture is more smooth. So it’s an avocado, it tastes like an avocado, but it’s a slightly different eating experience than Hass.”


What can cities do to correct racism and help all communities live longer? It starts with city planning
(The Conversation) Catherine Brinkley

The average life expectancy in the U.S. is 76.1 years. But this range varies widely – a child raised in wealthy San Mateo County, California, can expect to live nearly 85 years. A child raised in Fort Worth, Texas, could expect to live about 66.7 years.

Race, poverty, as well as related issues like the ability to find nearby grocery stores and easily visit clean parks, all influence health.

I led a team at the University of California, Davis Center for Regional Change to find out how California communities address environmental justice.

We collected over 500 finalized California city plans from 2020 through 2022. Plans are required to be updated every three to eight years, but we found that some places are still running on plans drafted in the 1970s.

How do wildfires start? Know the natural and artificial ways wildfires ignite.
(USA Today) Kristen Apolline Castillo, Aug. 18

…Wildfire season in the mainland United States quickly approaches as the summer season comes to a close. How do wildfires start? Luca Carmignani, a Fire Advisor from the University of California Agriculture and Natural Resources, says there are several ways wildfires may start.

…Historically, wildfire season typically begins in July and ends around late November to early December, Carmignani said. This time of year has the driest conditions which are perfect for igniting and burning vegetation.

“You have these drier months where you don't have a lot of rain, all of the grass and small vegetation that grew in the spring gets drier so it's easier to ignite and burn,” Carmignani said. “Also for example in a lot of parts of the states, those are months where you have strong winds.”


The real story behind that photo of a weirdly unscathed house in the rubble of Lahaina
(LA Times) Alex Wigglesworth, Aug. 18

Roofs are the No. 1 factor that contribute to the flammability of a home because they can serve as large landing pads for embers, said Susie Kocher, forestry advisor for the University of California Cooperative Extension, who co-authored a guide on how to harden homes against wildfire. In this case, a regular asphalt composition roof would likely have done just as good a job as metal, as most have a Class A fire resistance rating, she added...

...“One of the biggest sources of fuel is the homes,” she said. “So when one home goes up, if another is very close, the radiant heat can catch the other house.”

That risk is highest when the other building that burns is 30 feet away or less, said Stephen Quarles, UC Cooperative Extension advisor emeritus. Vulnerable components would be the siding, windows or under-eave area, as well as any foundation or attic vents, he added.

Most Wildfires Aren’t Forest Fires
(Heatmap) Jeva Lange, Aug. 16

…But if even firefighters need the occasional somber refresher to take grass fires seriously, then many of the rest of us have likely barely registered them as a threat. “I think a lot of people look at a grass fire and feel like, ‘Well, I could just go stomp it out,’” Barb Satink Wolfson, the University of California’s Cooperative Extension fire advisor for Monterey, San Benito, Santa Clara, and Santa Cruz counties, told me.

…Making matters worse, non-native grasses tend to quickly colonize and outcompete native plants after burns, in effect bridging fire further and further into landscapes where it doesn’t belong, such as deserts — or urban environments. “Those non-native herbaceous species are like the wick,” Max Moritz, a Cooperative Extension wildfire specialist and adjunct professor at U.C. Santa Barbara’s Bren School of Environmental Science & Management, told me. “They’re the place that fire can get a foothold on the landscape, even if the landscape wasn’t supposed to burn very often from a fire ecology perspective.”

In California, wildfires are prevented by crews of unlikely firefighters: goats
(NPR) Vanessa Romo, Aug. 10

…Lynn Huntsinger, a professor of rangeland ecology and management at the University of California, Berkeley, noted targeted grazing works best when it's used in combination with other wildfire reduction measures, especially prescribed burning.

"In an ideal world, we would have used goats or sheep or even cows, after the big fires we've had in recent years," Huntsinger told NPR.

That would have had the greatest impact in eliminating noxious and invasive plants, because the animals would consume any regrowth of the unwanted vegetation, she explained.


Wildfires Are Threatening Beloved Joshua Trees In The Mojave Desert
(KPCC) Aug. 9

Flames up to 20 feet tall have been spotted in the Mojave Desert as the York Fire has torn through mixed desert scrub, yucca, pinyon juniper, and invasive plants like red brome, all of which saw a lot of growth during the recent wet winter. Fires like this have long been rare in Mojave desert ecosystems, with some estimates putting the fire return interval at every couple hundred years. Now, they’re becoming a feature of the landscape, increasing in frequency and jeopardizing the recovery of native species, including Joshua trees. Just a few years ago, the nearby Dome Fire burned more than 40,000 acres and destroyed more than 1 million of the famous trees. Joining us today is Jacob Margolis, LAist science reporter and host of the ‘Big Burn’ podcast, and Lynn Sweet, research ecologist at UC Riverside, ??and Justin M.

…Scenes like these will become more common as the climate warms, said Justin M. Valliere, a plant sciences professor at the University of California at Davis who has studied what is known as the invasive grass cycle. It goes like this: After fires, landscapes like the Mojave can become more vulnerable to invasive species, which then grow faster and promote more fires, continuing a positive feedback loop.


California’s iconic sequoias are being incinerated by wildfires. Should we save them?
(SF Chronicle) Kurtis Alexander, Aug. 5

…In parts of the six groves targeted for planting, the park service has counted only a few thousand seedlings per acre a year after wildfire, less than 10% of the historical numbers, and fewer seedlings in year two.

“If we don’t plant the tree, it’s not going to be there,” said Robert York, assistant professor of cooperative extension in UC Berkeley’s forestry program, who is not directly involved in the park service plan but has worked for two decades on sequoia restoration. “These fires are behaving in a way that giant sequoias can’t really adapt to. When fires are high severity, they kill the seed supply, and they kill the trees that provide the seed supply.”

(New Scientist) Jeremy Hsu, Aug. 4

…Fire-spotting AIs could be especially useful “in open areas where there’s no people to call Cal Fire” or for monitoring long utility lines where equipment can spark fires, says Luca Carmignani, a fire adviser for the University of California Agriculture and Natural Resources. He also notes how AIs could automate analysis of live data from patrolling drones and orbiting satellites.

“There might be some false alarms,” says Carmignani. “But it’s better to have false alarms than seeing a fire later.”


Bridging a community: Elkus Ranch rebuilds after New Year’s even storms
(Coastside Magazine) Greta Reich, Aug. 1

On New Year’’s Eve, the educational leader of Elkus Ranch, Beth Loof, received a text message from the ranch foreman stating that the bridge had been washed out from the flooding waters. Not believing that it could be completely gone, Loof drove to the ranch to confirm – and, sure enough, before she even reached the bridge, she could its remants floating down Purisima Creek. The bridge that allowed access to the animals, barns and most of the Elkus Ranch grounds was gone. So began six months of rebuilding.

The ranch, a facet of the University of California Cooperative Extension under the Agriculture and Natural Resources Department, has been open since 1975 when Richard Elkus donated the property to the University of California. In the almost half-century since then, nothing of this level of destruction has ever happened.

The Mojave Desert is burning in California’s biggest fire of year, torching Joshua trees
(LA Times) Grace Toohey, Alex Wigglesworth, July 31

…“Most of the deserts in the southwestern U.S. are fairly fuel-limited in dry years, so there was that kind of natural fire break between plants or keeping it confined to relatively small areas,” said Christopher McDonald, a natural resources advisor at UC Cooperative Extension.


Why California is having its best wildfire season in 25 years
(Mercury News) Paul Rogers, July 30

…“I was in the mountains this past week,” said Scott Stephens, a professor of wildland fire science at UC Berkeley. “Things are green. Streams are flowing. It’s still wet.”

…“If vegetation is wetter it’s harder to ignite,” Stephens said. “You get lower flame lengths, and fire doesn’t spread as fast. Try to start a campfire with wood that has been wet from rain. It’s hard.”


Don’t Let Republicans Slash Fruit-and-Veggies Aid for Kids and Families
(Common Dreams) Sarah Manasrah, July 26

…The Republican proposal would slash a program we know is working. Enhanced fruit and vegetable benefits led to quick results: Within a few months of increased access, WIC children reported higher rates of fruit and vegetable consumption. In fact, a 2022 study from the National WIC Association and the Nutrition Policy Institute measured a ¼ cup per day increase in fruit and vegetable consumption for WIC-enrolled toddlers, helping young children get closer to federal recommendations, following the increase to WIC’s fruit and vegetable benefit.


San Ramon teenager presents innovative climate solutions in national competition

Scientists unveil new avocado variety known as the "Luna"
(Axios) Jennifer A. Kingson, July 24

…What they're saying: The Hass — the leading commercial variety globally — produces "a very high quality fruit, but one of the struggles is that it makes a very large tree," Mary Lu Arpaia, a co-inventor of the Luna UCR, tells Axios.

"Worker safety is an issue on large trees — you need to go up the tree with a ladder," says Arpaia, a UC Cooperative Extension horticulturist based at UC Riverside.

The Luna "tends to be a very tall but very slender, upright tree" that can produce "more fruit per cubic meter" and be harvested without ladders.

Plus, "the fruit has very good storage quality, and it ripens very well."


This is the robot that is scorching California’s fire-prone landscape
(SF Chronicle) Jack Lee, July 21

… “When the humidity is really high in the morning, nothing burns,” said Barbara Satink Wolfson, a fire adviser with UC Cooperative Extension. By contrast, BurnBot’s machine can start working earlier, before the marine layer burns off, because it produces so much heat, Satink Wolfson said.


Severe pruning during summer heat is hell for trees, not just striking actors
(LA Times) Jeanette Marantos, July 21

…Just like people, trees get stressed by high temperatures, and just like people, they need their own shade too, to protect the more vulnerable parts of their bark used to growing under their canopy of leaves, said Don Hodel, tree expert and retired horticultural landscape advisor to the UC Cooperative Extension office of Los Angeles County.

“Professional certified arborists definitely frown upon coat racking or hat racking, where you prune the tree so hard it looks like a hat rack,” Hodel said. “They might do it at the owner’s insistence but a reputable arborist will tell them this is bad for your tree and some will just refuse to do it at all.”

… That’s why trees really need their canopies during hot summer temperatures, said James Downer, a plant pathologist and horticulturist who teaches arboriculture at Cal Poly Pomona and just retired from the Ventura County UC Cooperative Extension office.

“Pruning those trees in this huge heat wave is unconscionable,” Downer said. “Everything depends on photosynthesis, so you cripple trees when you do this. This is the worst time to prune a tree, unless you really want to stunt its growth; then it’s a good time to do it because it will definitely have an impact.”


UC Diversified Agricultural Systems Program active in Mendocino and Lake Counties

(Ukian Daily Journal) Clebson Gomes Gonçalves, PhD, July 18

… The UC-Cooperative Extension – Diversified Agricultural Systems program that covers Mendocino and Lake Counties was created to implement an extension education and applied research program to develop and extend knowledge on high-priority initiatives on pomology and horticultural crops (i.e., pears, walnuts, and olives, as well as other niche crops such as vegetables, edible grains, seeds, nursery starts, ornamental crops, etc.) to an economically, culturally and socially diverse clientele. In collaboration with UCCE colleagues, the Diversified Agriculture advisor has worked to develop a strong integrated pest management (IPM) program to address ongoing problems faced by conventional and organic growers in the region and explore emerging technologies.

It was the bible for California winemakers. But what if it was all wrong?
(SF Chronicle) Esther Mobley, Yoohyun Jung, July 13

…At the center of this revolution in thinking is Elisabeth Forrestel, an assistant professor in UC Davis’ enology department — the same department that employed Winkler and Amerine. When Forrestel began to research the creation of the Winkler Index and learned just how crude its methodology was, she was shocked. 

… Now, Forrestel is charged with carrying out a 21st century retrofit of her predecessors’ work. Funded by an $800,000 grant from Winiarski, now 94, she is attempting to revise the Winkler Index. She hopes to create a tool that will better illuminate how to decide which grapes should grow in a given climate — this time, accounting for climate change.


Anger builds after controlled burn badly damages California sequoias
(LA Times) Alex Wigglesworth, July 12

Some experts worry the outcry over the Orphans will jeopardize efforts to safeguard other ancient groves.

They say that high-severity wildfire poses an existential risk to giant sequoias, which grow nowhere else in the world. Already, three fires in the southern Sierra are estimated to have killed nearly 20% of the population in just two years.

“If we’re going to say that if we can’t perfectly prep every single giant sequoia then we can’t burn, we’re taking a big gamble there,” said Kristen Shive, a fire ecologist and assistant professor at UC Berkeley. “It’s impossible to say you would never lose one in a prescribed burn, but you are going to lose far fewer in the long run.”

UC Master Gardeners hold pollination presentation
(The Desert Review) Kalin Turner, July 10

For this program, the UC Master Gardeners collaborated with the SPROUT program at the Imperial Public Library. The SPROUT program was funded in 2021 by the California State Library Grant to help provide families with early learning opportunities. The word SPROUT stands for Sing, Play, Read, Observe, Uniquely Together.

"At our event today, we have members of our team who have completed the 15-week training that is required to help learn about growing plants in the low desert. Today we will be able to provide children with the knowledge they need to understand why bees are so important for the growth of plants and how pollination is the key factor that enables the growth of different plants we find in the desert, said Master Gardener Program Coordinator Kristen Michelle Salgado.


'Devastating': California oak death is endangering the state’s signature barbecue
(SFGATE) Andrew Pridgen, July 10

“As a whole, oak loss is significant,” Steve Swain, a Marin County farm and environmental horticulture advisor for the University of California's Division of Agriculture and Natural Resources, told SFGATE. “Oak woodlands are really highly favored for building developments, and they weren’t really protected. That’s changing, but there are a lot of reasons why oak is going to get scarce.”

While Swain maintains that there “are still millions of oaks” here, when it comes to collecting the wood that keeps Santa Maria-style cookouts going, “you’re going after mature, dead trees, and that can be challenging.”


‘A unique responsibility’: Campaigns work to limit soda consumption, stop UC pouring rights contracts
(The Daily Californian) Matthew Yoshimoto, July 10

Since 2014, when a one-cent-per-ounce tax on all sugar-sweetened beverages was implemented in Berkeley, the tax was shown to discourage sugary drink purchases and increase sales of other beverages such as water. UC Berkeley’s pouring rights contract with PepsiCo outlines the beverage selection provided on campus.

Ken Hecht, a member of the Berkeley Soda Commission and coordinator at the UC Agriculture and Natural Resources Nutrition Policy Institute, explained limiting soda consumption can reduce the chance of contracting diet-related diseases such as diabetes.

He added the tax promotes environmental sustainability due to the large amount of water required to produce sugary drinks and the frequent discarding of microplastics during production.

“It’s simple economics,” Hecht said. “When the price goes up, the purchases go down, and that has (been) particularly effective in the neighborhoods where you want it to work best.”

Researchers create 'super strawberries' to keep billion dollar industry strong
(Spectrum News) Jamie Kennedy, July 7

The red berries are susceptible to soil-borne disease with one in particular that has become more prevalent, fusarium wilt.

The disease has been causing major concern and prompted UC Davis researchers like Steve Knapp to conduct a worldwide search for even hardier varieties.

“That showed up around 2005-06 in our state,” said Director of UC Davis Strawberry Breeding Program, Steve Knapp. “And has become increasingly problematic. It could wipe out production in California.”

Degree of storm damage in orchards still unknown
(Western Farm Press) Tim Hearden, July 6

… But since the buds for next year’s crop are formed in the current year, the unusually wet and cold spring of 2023 may also influence the crop size in 2024, UC Cooperative Extension farm advisers Elizabeth Fichtner and Mae Culumber wrote in a recent newsletter.

“The unusually wet winter and spring of 2023 has had unprecedented impacts on our local orchard systems,” they wrote in the UCCE’s Nut, Olive and Prune Programming News. “However, the cumulative impacts of a barrage of atmospheric rivers and persistent standing water in some flooded areas may not be realized for another year.”


Notice less sriracha? Shortage causes price spike, including in Sacramento stores
(KCRA) Maricela De La Cruz, July 5

Dan Sumner, an agricultural economics professor at UC Davis, said as long as people are willing to pay big bucks for the product, the price won't be coming down soon — at least until production picks up again.

"If you follow agricultural things, you know there are droughts and there are floods and there are pests and diseases," Summer said. "That's what farming is all about, and shortages mean higher prices."


Tyson drops ‘no antibiotics ever’ label on chicken products
(Food Dive) Chris Casey, July 5

… Tyson’s decision may signal a greater effort on behalf of poultry producers to prevent disease, after the significant impact of 2022’s bird flu outbreak. Vaccinating poultry, a proposed option the Biden administration said it is testing, is not popular among broiler chicken producers. University of California, Davis poultry health professor Maurice Pitesky told Food Dive earlier this year broiler chicken companies — which make 20% of their profits overseas — oppose vaccines because it would prevent them from selling it in regions that have stricter regulations than the U.S.


Opinion: Looking for the next California tech boom? You’ll find it in our farmlands

(Los Angeles Times) Joel Kotkin and Marshall Toplansky, July 2

… Howard-Yana Shapiro, a research fellow at UC Davis and former head of plant science at Mars Inc., says this state is the ideal place to marry the laboratory innovations of ag tech with its implementation at scale.

“The advancements developed in California,” he says, “for things like fruit trees that use significantly less water, or dairy farms that produce less polluting effluent, can then be extended to the rest of the world to build a more sustainable planet.”

… Today, ag tech research is through funding for the public universities and through private companies providing research grant money. California does not have a direct research grant program outside of the university system. (Over the last decade, the U.S. Department of Agriculture, the main public R&D funder for agriculture, has reduced its funding by one-third nationally.)

Given the crucial role that public-private collaboration plays in innovation, the state needs to develop focused incentives to help ag tech startups accelerate their efforts. The state has an R&D tax credit that is largely utilized by electronics and semiconductor research, which has helped that industry thrive. Now it needs to adopt similar approaches to enable ag tech to flourish.


UCANR CropManage Program
(AgInfoNet) Tim Hammerich, July 1

UC Ag and Natural Resources is putting years of research into practice with a technology of their own to help farmers irrigate and fertilize more efficiently. Michael Cahn is an Irrigation and Water Resources Adviser for UC Cooperative Extension based in Salinas. He explains this CropManage program.

Cahn… “It really began with a request from a grower. We were trying to help the farmers on the central coast, use nitrogen fertilizer more efficiently to comply with water quality regulations. We had a tool available, which is the soil nitrate quick test where we can test the soil very quickly to find out what is the level of mineral nitrogen that might be in the soil. And so a grower realizing he has a lot of different vegetable plantings asked if there was some sort of spreadsheet program that could assist him and also give him sort of an estimate of how much fertilizer you should apply. We slowly developed an online tool that can both help growers with water management and nutrient management.”

Burning Up
(Good Times) Blaire Hobbs, June 27

“Prescribed fire has been this black box of agency for so long,” says Barbara Statink-Wolfson, fire advisor with the UC Cooperative Extension. “PBAs put the process back in the hands of people: ranchers, indigenous tribes. And they get things on the ground much faster. They’re just another way to increase the pace and scale of treatments.” 


California's Insurance Fund for Prescribed Burns is First of Its Kind
(KQED) Guy Marzorati, June 26

California is now accepting applications for a first-of-its-kind insurance fund for prescribed burns. Those are fires lit on purpose to clean up brush and make an area more fire safe. KQED science reporter Danielle Venton talks with Lenya Quinn-Davidson, director of the University of California Agriculture and Natural Resources’ Fire Network.

“Unleashing prescribed fire as a tool in California is like a big puzzle. And five years ago, most of those puzzle pieces were not in place. And we’ve been slowly populating that.”

Lenya Quinn-Davidson, Fire Network director for the University of California Agriculture and Natural Resources, says the recent momentum is unparalleled.

“Californians are desperate to have a better relationship with fire, and only with innovative approaches like this claims fund will we be able to unleash the good work that needs to happen,” said Quinn-Davidson. “It's a challenging time to be working on fire in California, but also an incredibly inspiring time.”


Why dairy farmers dump their milk
(Ambrook Research) Jesse Hirsch, June 16

...dairy farmers rarely have enough storage on-site to keep stockpiling milk when cows are at their most productive — and it’s a highly perishable product. Compounding the problem, if a farmer wanted to send raw milk for processing outside their immediate area, it gets really expensive, really quickly. “It’s the ratio of weight to value that really matters here,” said Daniel Sumner, professor of agricultural and resource economics at University of California, Davis. “This means I really can’t afford to drive a truck full of milk very far before it’s just not worth hauling it.”


Calif. prune crop could size up well this year

Two Historic Giant Sequoias in CA Park Damaged in Prescribed Burn
(Modesto Bee) Dominique Williams, June 13

… Kristen Shive, a fire ecologist and assistant professor at UC Berkeley, did not see The Orphans in person, but saw photos of them and said it looks like the crown damage was the result of heat from fire on the forest floor and from fire that consumed a neighboring non-sequoia tree.

… Shive said it's impossible to do a prescribed fire with zero risk to the sequoias.

"The only alternative to that risk is to do nothing," Shive said. "Doing nothing would keep the groves fuel-loaded and at high risk of severe fire that has the potential to kill far more of these incredible trees."


In burned-out groves of giant sequoias, crews plant seeds of hope. Will they survive?
(LA Times) Alex Wigglesworth, June 11

The planting at Alder Creek Grove is not just a preservation effort, it’s also an experiment.

“Ultimately, what I want to know is how we actually can recruit or develop monarch trees,” said Rob York, professor of Cooperative Extension, who is leading the study.

York plans to hold a prescribed burn in the grove in about 12 years to mimic the natural pace of fire in the forest. He wants to determine how densely giant sequoia seedlings should be planted now to ensure the grove thrives after that burn.


The big bet on meat alternatives fails
(Newsweek) Katherine Fung, June 11

While Beyond Meat was worth more than $14 billion in 2019, it was valued at $827.24 million as of Friday. Its shares have fallen about 95 percent over the past four years.

Daniel Sumner, an agricultural economics professor at the University of California, Davis, told Newsweek that this often happens with innovative alternatives to conventional products.

"Sometimes the market expands enough to justify early investment. Often the early investments do not pan out either because that market segment never takes off and sometimes because early entrants are overtaken," Sumner said.


Prescribed fire severely damages pair of iconic giant sequoias in Calaveras Big Trees State Park
(Union Democrat) Guy McCarthy, June 9

Kristen Shive, an ecosystem scientist at the University of California, Berkeley, examined photos of the Orphans this week and emphasized she has not seen the badly scorched trees in person. She recently studied how wildfires can damage giant sequoias.

“The tree on the left probably has enough green foliage to survive,” Shive said Thursday. “For the tree on the right, in the photos it looks like there is no green at all,” Shive said. “If that’s the case, then it is dead. If there is some green that is just not visible in the photos, it could have a chance, as they can sustain pretty high crown damage and survive.”

Shive was lead researcher with five others on a 2022 study, “Ancient trees and modern wildfires: Declining resilience to wildfire in the highly fire-adapted giant sequoia.” Their study of recent wildfires found that trees with a large fire scar at their base can take roughly 85 to 90% crown loss, and still survive, Shive said Thursday.

“Unfortunately, it’s impossible to do a prescribed fire with zero risk to the sequoias,” Shive said. “The only alternative to that risk is to do nothing. Doing nothing would keep these groves fuel-loaded and at high risk of severe fire that has the potential to kill far more of these incredible trees.”


Why deadly hemlock is suddenly growing all over the Bay Area — and how to spot it
(SF Chronicle) Nora Mishanec, June 8

… Pets are especially at risk of fatal poisoning if they ingest the plant, which has a larger footprint this year following winter’s historically heavy rains, said Steven Swain, an environmental horticulture advisor to Marin and Sonoma counties. 

Wildlife experts are sounding the alarm about the poisonous species, whose umbrella-shaped rosettes and feathered leaves are toxic when eaten, even in small amounts. 

“Cats and dogs occasionally nibble on plants, and it doesn’t take more than a few leaves to be fatal,” Swain said.


Melon Growers Gain Ground on Cucumber Beetle
(Growing Produce) Thomas Skernivitz, June 7

Cucumber beetles — both western striped and western spotted — remain a major problem to muskmelon growers in the Sacramento Valley for at least three reasons.

According to Amber Vinchesi-Vahl, an Area Vegetable Crops Advisor with the University of California Cooperative Extension (UCCE), those reasons include:

  1. Conventional melon systems have very low thresholds for damage.
  2. Cucumber beetle populations tend to be very high.
  3. Organic growers rely on a limited number of tools in defense.

… “So, we’re working to improve IPM in melons for cucumber beetle.”


‘California is meant to burn': Experts teach landowners art of prescribed burns
(Reuters) Nathan Frandino, June 1

The prescribed burn begins on a California hill with a drip torch to light brush, needles and fallen branches, the flames spreading out on the forest floor far below the tree canopy.

Students on this Saturday class learn how to keep the burn under control, while others stand by ready to assist with water pumps, hand tools and first aid.

Teaching locals is exactly what Susie Kocher is hoping to accomplish through the El Dorado Amador Prescribed Burn Association. Founded in 2021, the association teaches private landowners about prescribed burns, including how to plan and carry them out safely.

First drought, then flood. Can the West learn to live between extremes?
(New York Times Magazine) Brooke Jarvis, May 31

In the Central Valley, Helen Dahlke, a hydrologist at U.C.-Davis, is working with farmers to experiment with diverting floodwaters to their vineyards, fields and orchards: Where does it infiltrate best? What crops are most capable of handling it? She told me that when she first came to California 10 years ago, the primary goal for floodwaters was to get rid of them: to confine them to narrow channels, to move them off the landscape as quickly as possible. When she tried to push farmers to hold floodwater on their cropland so it could recharge the groundwater below, most thought she was nuts.

They were designed to be safer: How de-horned cows created at UC Davis were doomed
(San Jose Mercury News) Lisa Krieger, May 29

Under rigorous federal rules established in the early years of the genomic revolution, and upheld during the Obama administration, genetically modified animals are considered to be a new type of veterinary pharmaceutical, needing FDA approval. Without it, meat and milk can’t enter the food supply. As a result, the nine cows — and the experiment — are now dead, burned, at a cost of $1,200 each.

“It was a waste. There wasn’t any risk,” said animal geneticist and professor Alison Van Eenennaam of UC Davis, who spent seven years on the project. “Basically, they were an unapproved drug.”


Ground Rules: Can the Sustainable Groundwater Management Act ensure sufficient, safe, and equitable water for all Californians?
(Breakthroughs) Zac Unger, Spring 2023

In response to this crisis, California lawmakers passed the Sustainable Groundwater Management Act (SGMA) in 2014, a package of bills that require local and regional authorities to actively regulate groundwater use and create sustainable management of groundwater by 2042. “Prior to that, we had no systematic management of groundwater at all,” says Kristin Dobbin, an assistant professor of Cooperative Extension in the Department of Environmental Science, Policy, and Management, noting that “we were the last state in the West to enact a management plan.” 

...A big part of the reason why groundwater supplies in California are so tenuous comes down to their relationship to property rights. “If you own a parcel of land in California, you have the right to use the groundwater underneath that land,” explains Ellen Bruno, an assistant professor of Cooperative Extension in the Department of Agricultural and Resource Economics. “You’ll pay the cost to drill the well and the energy costs to extract it from below, but that’s it.” 


Castroville vs. Coachella: Battle heats up to grow the perfect California artichoke
(San Jose Mercury News) Julia Prodis Sulek, May 28

This revolution has uprooted thousands of acres of heirloom artichokes across Castroville — the “Artichoke Center of the World” — and replaced them with hybrids. Now, it’s pitting technology against tradition and playing out at farm stands and on dinner tables across the country.

The new varieties are cheaper to grow, have a longer shelf life and resist diseases, said Steven Fennimore, a UC Davis plant science professor.

But what about flavor?

“You can argue about taste all day,” he said, “but I won’t get into that.”


California Tree Nut Growers Bat Lead Off in Climate Change Workshops
(Growing Produce) David Eddy, May 22

To understand just how different farming is in California, consider the fact experts no longer believe the standard way of estimating chill hours — the number of hours in the winter between 32ºF and 45ºF — is all that useful in the Golden State, as “chill is just a guess,” says University of California Cooperative Extension (UCCE) Orchard Crops Advisor Phoebe Gordon.

“It was not developed for California,” Gordon told an audience in Merced, CA, in late March at the Climate Smart Agriculture for Nut Production Workshop, noting the model was developed by scientists in colder climates. “They don’t tend to get 65°F in the middle of January.”


El Niño is back, bringing disruption, danger for California, world. ‘We need to be prepared’
(LA Times) Hayley Smith, May 19

...There are also potential direct effects to California’s agriculture, said Tapan Pathak, a specialist in climate adaptation in agriculture at the University of California Cooperative Extension.

El Niño’s agricultural effects in the state are usually most evident during wintertime, when warmer temperatures — especially warmer minimum temperatures — can negatively affect crops that require a higher chill during winter dormancy, such as pistachios, cherries and pears, Pathak said.

Warmer winters can also mean more pressure from pests, which might start their cycle earlier, he said. Earlier bud-breaks and flowering, as well as a longer growing season, are also possible.


What John Deere’s strong earnings say about the farm economy
(Marketplace) Savannah Maher, May 19

…When consumers invest in big-ticket items like cars, sofas and washing machines, they’re usually feeling optimistic about their finances. The same goes with farm equipment, said Daniel Sumner, an agricultural economist at the University of California, Davis. 

“When farmers have a little extra cash flow and they don’t see a crisis looming right now,” he said, that’s when they replace their tractor fleets. 

And when John Deere is moving a lot of machinery, Sumner said, that indicates growers of global commodity crops are doing well. 

“That is to say the corn, soybeans, wheat and rice,” he said. All of those were in extra high demand after Russia invaded Ukraine last year.


USDA Considers Banning One Of The Best Parts Of School Lunch: Chocolate Milk
(KPCC) AirTalk, May 19

The U.S. Department of Agriculture is considering taking flavored milks, including chocolate milk, off the menu in school cafeterias. The move could come as the group enacts the latest standards for school nutrition, according to the Wall Street Journal.

Joining to discuss how these policies are considered and implemented is Wendi Gosliner, senior researcher with the Nutrition Policy Institute at the University of California Agriculture and Natural Resources.

Over time, studies find theres a rebound. There may be initial drop. Over time they go back to selecting milk.13% drop, but no change in consumption. More than half were before policy took effect were selecting chocolate milk. Most of the students who had been selecting chocolate milk selected the plain milk.

Alison Van Eenennaam, extension specialist in animal biotechnology and genomics at UC Davis, isn’t hopeful that genetically engineered meat will be sold anytime soon in the U.S. She blames an outdated regulatory structure that doesn’t account for the rapid scientific advances made in recent years. “We need a different language because when the Food, Drug, and Cosmetic Act was written, what, 40 years before the discovery of DNA, they were not envisioning genome-edited animals,” Van Eenennaam said. “To me, the only thing that’s going to change this is that Congress has to go and say, ‘This is stupid’ … and they have a few other things on their plates right now.”


Efforts to recharge California's underground aquifers show mixed results
(NPR) Nathan Rott, May 17

…ROTT: So now, when there's too much water, why not just put it back underground? That's what Khaled Bali, an irrigation specialist with the University of California, is trying to do at this research plot in the Central Valley.

KHALED BALI: Groundwater recharge is basically taking excess flood water and putting it in the underground aquifer.


Company hopes to test wildfire detection system in Ramona this summer
(Ramona Sentinel) Julie Gallant, May 16

…Luca Carmignani, a fire adviser at the university’s South Coast Research and Extension Center, observed the test while conducting separate research on the effects of irrigation on the flammability of plants.

“It’s definitely an interesting project that would allow for the detection of fires in an urban environment very quickly,” said Carmignani, adding he was was not directly involved in testing the Sentinel and is not endorsing it. “Rather than relying on a call from someone reporting smoke they would have a camera detect it immediately. The project itself sounds very interesting and useful for firefighters.”


Researchers explore risks of grazing sheep on pastures after wildfires
(Capital Press) Sierra Dawn McClain, May 16

In a new study published in the journal California Agriculture, the University of California-Davis explored whether sheep grazing on pastures that have regrown after wildfires are negatively impacted by metal contaminants and altered minerals....

..."We didn't get striking evidence that tells us, when there's a fire, it means everything is contaminated with heavy metals. But it does raise the question that maybe we should be doing a little bit of surveillance to see if this is spurious or common. And we should be finding a way to screen grazing herds," Sarah Depenbrock, assistant professor and agronomist in the UC-Davis School of Veterinary Medicine, said in a news release.


Annual sudden oak death survey underway to test for spread, activity of tree-killing organism

...volunteers and LandPaths staff are contributors to California’s SOD Blitz Project, an annual survey that helps measure the extent of a disease that has gradually marched along the coast of California since it was discovered in Marin County in 1995.

The idea is to catch it early, in the vector host, before it can spread to a susceptible tree, said Matteo Garbelotto, adjunct professor and Cooperative Extension Specialist at Cal Berkeley, who launched the SOD Blitz in 2008.


Mangoes and agave in the Central Valley? California farmers try new crops to cope with climate change
(CalMatters) Alastair Bland, May 9

Climate change essentially means that Southern California’s conditions are creeping north up the coast and into the valley, while Oregon and Washington are becoming more like Northern California. Precipitation, winds, fog, and seasonal and daily temperature patterns — all of which determine which crops can be grown where — have all been altered.

“With climate change, we’re getting more erratic entries into fall and more erratic entries into spring,” said Louise Ferguson, a UC Davis plant physiologist....

...Research...suggests that high winter temperatures could severely reduce walnut yields about once a decade. 

Katherine Jarvis-Shean, an orchard advisor with the UC Agriculture and Natural Resources program, said that effect will be magnified farther south: “That’s probably one in five years in the southern San Joaquin Valley,” she said....

...Warmer winters can cause male varieties to bloom and release pollen too late, after the female flowers have opened. This means less pollination and less fruit, and in 2015 many orchards suffered total crop failure.  

Patrick Brown, a UC Davis nut crop breeder, said farmers have solved this problem, at least for now, by grafting additional male varieties with different blooming schedules into the groves. “It’s a fairly easy hedge against that problem (of warmer winters),” he said. “No matter when the females bloom, there should be some pollen for them.”...

...Another tropical fruit more suitable for drought-prone land is the pitaya, or dragonfruit. Grown from tropical cactus plants, it can be farmed in California with as little as 1.5 feet of applied water — a third of what citrus and avocados need, according to Ramiro Lobo, a San Diego County farm advisor with the UC Cooperative Extension program. His program has distributed about 50,000 dragonfruit cactus cuttings to small farmers from San Luis Obispo down to San Diego and at least 1,000 acres are in production....

...Daniel Sumner, a UC Davis professor of agricultural and resource economics, said California’s agricultural identity already has changed drastically over time. In its earliest days of statehood, California was a major producer of rain-watered wheat, grown on several million acres. When irrigation became ubiquitous, so did specialty crops that thrive in a hot, dry climate but need water in the summer....

What can Northern California expect this wildfire season? Risk depends on where you live
(Sac Bee) Hanh Truong, May 2

With the winter rain and snow, certain ecosystems in Northern California may be spared of some of the ravenous fires that usually spark in late spring to fall, said Dr. Andrew Latimer, professor of plant ecology at the University of California, Davis.

Areas with more trees and shrubs, such as conifer forests in the mountains and redwood forests, may have less fire activity in the summer compared to the last two years, said Latimer, who researches how forests and grasslands respond to drought and fire. This is due to the snowpack, which will likely last longer into the summer, giving fires less time to start and spread, he said.


Big wildfires can devastate California’s fish. But they thrive with frequent, small burns
(KQED) Danielle Venton, May 1

“If we don’t have a good grasp of what’s going on with fire, there’s no way we can manage for things like fish, for people, for communities or anything, really,” said Lenya Quinn-Davidson, director of the University of California Agriculture and Natural Resources’ Fire Network, addressing a crowd gathered for a healthy fire and fish workshop at the 40th Annual Salmonid Restoration Conference last week in Fortuna.

The crowd, composed primarily of fish devotees from nonprofits, regulatory agencies and universities, had gathered to spend the day discussing how the fates of fire and California’s beloved charismatic aquafauna are intertwined.

“The future of fire is the future of fish,” said Quinn-Davidson.

'The big melt is now here': California braces for floods
(NBC News) Evan Bush, Jiachuan Wu and Kathryn Prociv, April 27

...Flood worries are centered on the San Joaquin River system, the Tulare Lake Basin and some parts of the Eastern Sierra, which don’t have as much capacity to control flooding and are fed by the outsize, high-alpine snowpack in the central and southern Sierra.   

“In the southern Sierra, where we have the deepest snowpack, at some points we have about 5-6 feet of water sitting in the snowpack,” said Safeeq Khan, an assistant adjunct professor of civil and environmental engineering at the University of California, Merced. “Imagine 5 feet of water coming down within five or six weeks – how do you go about managing that water?”

After the deluge: Floods may taint more drinking water in California
(CalMatters) Alastair Bland, April 19

… Helen Dahlke, a UC Davis professor of integrated hydrologic sciences, said stormwater percolating into the ground will flush soil nitrates into groundwater basins, causing levels to jump.

Whether the concentrations drop again soon “depends on how much clean water comes along on the back end,” she said. Flooding will probably provide enough water to dilute nitrate-tainted runoff, while groundwater basins recharged by rainfall alone are likely to remain elevated, she said.

…Thomas Harter, a UC Davis professor who co-authored the nitrate report for state officials, said the contamination will haunt at least another generation of Californians. That’s because the lag time between the application of fertilizer and its entry into groundwater basins can be many years, and decades more may pass before the nitrate reaches a well. 

“Even if we were able to change how we manage agricultural fertilizer today, it would still take years or decades before wells actually see an improvement,” he said.

These farmers recharged groundwater by catching atmospheric rivers
(Civil Eats) Grey Moran, April 17

“The groundwater reserves we have stored underground are so much larger than any surface water storage that we have combined in rivers, lakes, and man-made reservoirs. So, it really is a much more convenient way of storing water for multiple years,” said Helen Dahlke, who leads a laboratory focused on catchment hydrology under a changing climate at the University of California, Davis. “California is coming to realize that our surface water storage is only typically carrying us over for two or three years,” she added.

Commentary: How managing flood flows can help rescue aquifers
(Ag Alert) Thomas Harter, Mallika Nocco, Isaya Kisekka and Helen Dahlke, April 12

As a changing climate stresses water supplies, a key focus for California is on how to manage flood flows in ways that store more water for drought years while reducing risk to life and infrastructure.

A potential solution to this question is to enhance groundwater recharge, a natural process in the water cycle that leaks water from rainfall, rivers or flooded areas into the subsurface. Natural recharge is no longer enough to refill our overtapped groundwater reserves. But intentional, managed aquifer recharge, or MAR, can help reduce flood risk and store more water for dry periods.


Fighting fire with fire in California
(Smithsonian Magazine) Andria Hautamaki, April/May issue

The Plumas Underburn Cooperative and other Prescribed Burn Associations (PBAs) were founded on the belief that by sharing equipment and labor—and with proper training and experience—neighbors can manage fires together safely and effectively. First formed in the Great Plains in the mid-1990s, this collaborative model has since spread across the United States. In California, the first PBA was established in 2018; now, the state has 22. “Communities are desperate for solutions,” says Lenya Quinn-Davidson, a fire expert with the University of California Cooperative Extension. “Many of the landowners and people involved want to restore fire to the system. They’re inspired now, because they’re seeing it happen in other places.”


Sudden Oak Death Blitz planned for May 12-14
(Lamorinda Weekly) William Hudson, April 12

... Professor Matteo Garbelotto's lab at UC Berkeley has been studying SOD and ways to combat it since its arrival in California. A key part of these efforts is the lab's annual spring SOD Blitz-signifying intense effort in a short period of time-a citizen science survey of Bay leaves with characteristics that are produced by SOD, but also other causes. To determine the actual presence of SOD, the leaves are analyzed over the summer, and in the fall the location and actual infected status of each sample is displayed on a Google Earth map viewable at www.sodblitz.org. There is no cure for infected trees, so the Blitz information is critical to determining the areas most at risk in which to focus efforts to prevent infections; the fall is the best time for the measures to protect the oaks against infection in the following spring.


Why California Can’t Catch a Break
(The Atlantic) Caroline Mimbs Nyce, April 11

… But in the long term, all of this vegetation might be a problem. Plants, both living and dead, are fuel, so a productive spring growth could bring trouble when the heat hits and things dry out. Lower-lying grassy areas are particularly at risk. Research has shown that “some of our biggest wildfire years have been drought years that’ve followed really good rainfall years,” Leslie Roche, a professor at UC Davis in the plant-sciences department, told me. “If we go from a really, really good year to a really, really extreme drought year again, the risks there are magnified.”

California just can’t catch a break. Part of the problem is its unique boom-bust climatology: The state always seems to go big, and that includes its weather cycles. “When it’s dry, it’s really dry. When it’s wet, it’s really wet,” Faith Kearns, a researcher at the California Institute for Water Resources, told me. (This variability has to do with the jet stream, the position of which affects both the number of winter storms that hit California and their size.) Changes to the planet’s climate are supercharging this ping-pong effect, creating what researchers call “climate whiplash.”

…The state’s water infrastructure isn’t designed to handle the climate whiplash, Ted Grantham, a professor who studies water management at UC Berkeley, told me: “We really need to start making decisions and investments in adapting to this new normal.” Because the next disaster will come. This year, next year, or later, there will be floods. There will be wildfires. There will be another drought. Living in California means having to prepare for all of those threats, sometimes in quick succession.


After a crippling drought, California has enough water to grow rice this year. Its troubles aren’t over.

… This year, “There’s a lot of optimism out there,” said Luis Espino, rice farming systems advisor for Butte and Glenn Counties at the University of California Cooperative Extension. 

… When there’s no water, there’s no rice, and no one is naive enough to believe that drought will never come again or that the state’s rice production is saved forever. “Growers have to think about this as the new normal, where some years we have water and some years we don’t,” Espino said. Which means strategies abound for ways to prepare for upcoming water shortages in order to become more resilient.

Here’s where California’s remarkably wet year is bringing welcome recovery
(LA Times) James Rainey, April 1

The path for spawning salmon also will be eased by the surfeit of water.

“When we’re in drought, it makes it very difficult for fish to move upstream and also for juvenile salmon trying to get back to the ocean,” said Ted Grantham, a freshwater ecologist and hydrologist with UC Berkeley’s Department of Environmental Science, Policy and Management. “All this water should smooth their way.”

High rivers have also created more overflows into natural and human-made floodplains. The water soaks up nutrients, enriching the waterways. “That creates perfect conditions for a lot of wildlife, including for fish growth,” Grantham said. “Salmon can get fat before moving out to the ocean and that means they are much healthier and have a better chance for survival.”

Sensors to help fine-tune precision irrigation systems
(Agronomic Minute, AgNet West) March 22

Associate Professor of Hydrology and Irrigation at UC Davis, Isaya Kisekka has been looking at different sensor technology in almonds. Some options appear to have some good potential for growers.

“For a long time, we have not had a tool that allows us to measure stem water potential remotely. You can think about stem water potential as the amount of work that the plant has to do to pull water from the soil,” said Kisekka. “More recently, we now have sensors that appear promising to give us data that is comparable to a pressure chamber or a pressure bomb.”


Amid soaking storms, California turns to farmland to funnel water into depleted aquifers
(LA Times) Ian James, March 21

The governor’s order is a positive step, said Helen Dahlke, a professor in integrated hydrologic sciences at UC Davis. She hopes the order may help “trigger some new movement to revise what system we have in place to get these high flows diverted for groundwater recharge.”

The current regulatory system is cumbersome and bureaucratic, requiring water agencies to hire consulting firms and lawyers, Dahlke said. Many applications are rejected the first time, she said, and it typically takes months for an agency to get a permit approved.

Dahlke said she hopes state officials speed up the process. The system should strike a balance between maintaining needed river flows for the environment and replenishing aquifers, she said.


Explainer: What California's atmospheric rivers mean for drought, floods, fires
(Reuters) Steve Gorman and Daniel Trotta, March 21

During any normal 20-year period of the 20th century, about 10 years were wet and 10 years were dry - a sustainable ratio, said Thomas Harter of the University of California at Davis. During any normal 20-year period of the 20th century, about 10 years were wet and 10 years were dry - a sustainable ratio, Harter said. But in the past 25 years, only nine years were wet and 16 were dry, meaning the state needs seven more wet years to recover. And climate change points to future years that are likely to get warmer, exacerbating the increasingly dry climate.

Bird flu: What is it and what's behind the outbreak?
(BBC News) Helen Briggs & Jeremy Howell, March 20

China has been vaccinating its domestic poultry flocks.

However, other countries avoid this because it is hard to judge which birds have been made immune and which have not - and so the meat and eggs from vaccinated flocks cannot be sold abroad.

"There are strict export controls when a country decides to vaccinate," says Dr Maurice Pitesky of the School of Veterinary Medicine, University of California, Davis.

How California is using recent floods to prepare for future drought
(Washington Post) Allyson Chiu, March 15

The technical term for the process of diverting or taking surface water and storing it underground is “managed aquifer recharge,” said Helen Dahlke, a professor and groundwater hydrologist at the University of California at Davis.

“We do it in a controlled way,” Dahlke said. “We are not talking about unintentional or natural recharge that’s happening just as a result of precipitation, rainfall falling onto soils and then infiltrating.”

Instead, she said, the approach typically involves taking water from one location, directing it onto a certain parcel of land and letting it percolate down into an aquifer.


Much of California has escaped drought, but what lies ahead?
(The Hill) Sharon Udasin, March 18

But with such an influx of water also come many challenges — including the risk of dangerous floods, as well as a need to improve methods for filling up depleted groundwater reservoirs.

“Coming out of a drought and having this much snowpack in the mountains and a threat of floods, clearly there is a big interest in squirreling away as much of this water as we can,” Thomas Harter, a professor of water resources at University of California, Davis, told The Hill.

Snowmelt this spring could lead to “welcomed water supply benefits” in much of California and the Great Basin, while helping boost key Colorado River reservoirs, according to NOAA.


California will use floodwater to recharge groundwater
(LA Times) Ian James, March 11

Harter said 600,000 acre-feet is “a significant chunk, and it’s certainly an important stepping stone toward future wet years and getting to these goals.” He said the water stored underground can allow for eventual cutbacks in well-water use to be somewhat less severe than the reductions would otherwise need to be.

As US mulls vaccinating poultry for bird flu, chicken industry could stand in the way
(Food Dive) Chris Casey, March 9

A number of vaccines against different strains of bird flu have been developed and tested on flocks in recent years. Vaccinating birds was mandated in China in 2017, according to health organization Gavi, the Vaccine Alliance. These vaccines have shown strong efficacy, said Rodrigo Gallardo, a poultry medicine professor at University of California, Davis.

“In terms of the feasibility of vaccination and how to do it, that’s already proven,” Gallardo said. “It’s more of a political problem.”

But the broiler chicken industry could be the main group standing in the way of the industry embracing immunization.

The HPAI vaccines have not been used on a large scale in the U.S. because of the ramifications the inoculations would have on international trade of chicken products, said Maurice Pitesky, a poultry health and food safety epidemiology professor at UC Davis.

“Vaccination, as we all know from COVID, protects against the disease but doesn’t protect per se against infection,” Pitesky said. “The worry is that the product could spread HPAI around the world.”

Editorial: Can California's legal cannabis industry survive while illegal competitors still operate?
The San Diego Union-Tribune, Feb 20

… It's a tall order. As long as illegal cannabis products cost half as much as legal ones — as documented last year by University of California, Davis economists Robin Goldstein and Daniel Sumner — they will dominate sales. Voters' 1996 approval of a law allowing legal "medicinal" cannabis — with buyers essentially self-attesting to why their health issues required its use — set up a multibillion-dollar industry that often skirted state laws. A prescient 2018 analysis by the Southern California News Group noted that the industry was only emboldened by the fact that Proposition 64 reduced the penalties for most cannabis crimes and eliminated others entirely.

…“Gone are the days where coyotes are coming from the hills for a drink,” said Niamh Quinn, a human-wildlife interactions advisor with the University of California’s Department of Agriculture and Natural Resources.

“I think that people need to know that coyotes are everywhere, like literally everywhere. Just because you don't see coyotes doesn’t mean that they're not in your neighborhood.”

The edges matter: Hedgerows are bringing life back to farms
(Civil Eats) Anne Marshall-Chalmers, Feb. 14

About 30 years ago, Rachael Long, a farm advisor with the U.C. Agriculture and Natural Resources (ANR) began preaching the power of hedgerows to farmers in the Sacramento Valley. She eventually followed her own advice and planted a half-mile stretch of redbud, coyote brush, toyon, and other native California species at the edge of her tomato and wheat farm.


More vineyards opt to send in the machines
(Good Fruit Grower) Matt Milkovich, Feb. 13

… To educate Michigan and Midwest growers about the adoption of vineyard mechanization practices in California — by far the largest grape-producing state — Nasrollahiazar asked Kaan Kurtural to speak at the Great Lakes Fruit, Vegetable and Farm Market EXPO in Grand Rapids, Michigan, in December. Kurtural, an extension specialist with the University of California, Davis, spoke virtually. 

… Combine the cost of labor with the limited availability of land and foreign competition, and the case for mechanizing vineyard management tasks has never been clearer, Kurtural said.

“There’s really no other alternative at this point,” he said.


A battle to save Beverly Hills' shady ficus trees is underway
(LA Times) Dorany Pineda, Feb. 13

Not only do trees filter pollutants from air and quell storm water runoff, they also help cool surface temperatures during extreme heat waves with shade and transpiration.

“Those two combined processes can result in black asphalt surfaces that otherwise could be 140, 150 degrees in L.A., or out in Coachella 170 degrees, to be cooled down, in Coachella, about 100 degrees, and in L.A. down to 80 degrees,” said Janet Hartin, an environmental horticulture advisor with the UC Cooperative Extension in Los Angeles, San Bernardino and Riverside counties.

Yet when trees are not being killed off by drought, disease and insects, many mature shade trees that offer more environmental benefits are being cut down. Less than half of the trees planted in urban settings live to be 20 or 30 years old because of poor tree selection and care, Hartin said.


Why historic storms are 'both a blessing and a curse' for California's fire season
(San Francisco Chronicle) Jack Lee, Feb. 12

If the state continues to see wet weather over the next few months, vegetation will stay damp, making it less likely for a blaze to rapidly spread. The moisture also means healthier forests and fewer dead trees.

“That’s going to reduce the chance for a real big forest mortality event like (what) happened (from) 2012 to 2015 in the southern Sierra Nevada,” said Scott Stephens, a fire science expert at UC Berkeley. “That drought — 2012 to 2015 — killed 150 million trees.”


Why are California's trees dying?
(New York Times) Erik Vance, Feb. 10

...Last year saw a shocking 16 times more dead Douglas-firs than the previous one. In other words, the trees that should be the most able to survive the drought are now dying in large numbers.

Doug fir is probably one of the most resilient species in the Sierra Nevada,” said Scott Stephens, a forestry professor at the University of California, Berkeley. “It is the last species that actually has not been really significantly impacted.”

In a dramatic spike, 36.3 million trees died in California last year. Drought, disease blamed
(Los Angeles Times) Nathan Solis, Feb. 7

…The statewide results are alarming but not surprising to Ryan Tompkins, a forester and natural resources advisor at the University of California Cooperative Extension. Starting in early 2022, CalFire was sounding the alarm on tree mortality in Northern California. 

“The real problem here is that our forests are far too dense. And when these forests are really dense, trees are competing for a finite amount of water, particularly in a dry year,” Tompkins said. “While we see these periodic droughts and these periodic tree mortality events, some of this is driven because we’ve normalized these very dense forests.”


The Census of Agriculture: what it's for, why it matters

California’s Lost Trees
(NY Magazine) Alissa Walker, Jan. 13

…Yet the storms’ destruction isn’t just about losing a beautifully leafy landscape. Urban forestry is a crucial front against an increasingly hotter climate, according to a forthcoming paper published by the University of California’s Agriculture and Natural Resources Cooperative Extension. “While all plants cool the surrounding environment through transpiration, trees play a particularly important role in mitigating climate change by shading urban heat islands,” Janet Hartin and Rob Bennaton write. This is in addition to removing the carbon dioxide from the atmosphere that contributes to greenhouse-gas emissions in the first place. So when the hyper-saturated soil combines with 70 mph winds, it sends the city’s best tools of resilience smashing into sedans parked on side streets. This is the challenge to come in the wake of the current crisis: After the storms quiet and rebuilding begins, how do cities replace critical urban infrastructure that took up to 100 years to grow?

California Chill Report: Storm Impacts on How Trees Experience Chill
(AgNetWest) Jan. 11

Most of California has been experiencing a substantial amount of rain since the end of 2022 and that can have an impact on how trees are experiencing chill. UC Cooperative Extension Orchard Systems Advisor for Yolo, Solano, and Sacramento counties, Kat Jarvis-Shean said that the weather can be measured as “anywhere from neutral to good” as it relates to chill accumulation. The impact on winter chill has less to do with overall temperatures and more to do with sun exposure.

“When we have these overcast days or these stormy, cloudy days during the daytime, the suns not getting through to the buds. So, they’re sort of shrouded from the sunshine and the energy and the heat that that sunshine gives,” Jarvis-Shean explained. “When we have low chill winters, it often coincides with dry, drought winters, because we have clear sunny days, and those flower buds and vegetative buds are just cooking out there in the sunshine.”

Ongoing egg scarcity has Long Beach restaurants considering price increases
(Long Beach Post) Alicia Robinson, Jan. 9

…The last major U.S avian flu outbreaks were in 2014 and 2015, and they also sent egg prices soaring, but there are some important differences, said Maurice Pitesky, an associate professor at the UC Davis School of Veterinary Medicine Cooperative Extension.

About seven times more counties around the country have been affected this time around, so “the scope of the outbreak that we’re dealing with right now is basically much larger geographically,” he said.

Also, five or six years ago, the number of infections died down during the warm summer months and didn’t flare back up the following winter, Pitesky said, but the current wave didn’t go away in the spring and summer.


South LA school teaches students to cultivate green thumbs
(LA Times Today/Spectrum News 1) Jan. 6

Getting children to eat vegetables is a challenge as old as time. Research has shown that one strategy to entice kids to eat more greens is by cultivating their green thumbs with a school garden.

Islah Academy is a small community school in South LA that’s taking their young learners out of the classroom and putting their hands into the soil.

"We provide gardening assistance to all of the schools and organizations throughout Los Angeles County," said UC Master Gardener Sum-Sum Chan. "We're here to beautify this school."


What this series of atmospheric rivers says about California’s drought and water future
(Capital Public Radio) Manola Secaira, Jan. 6

While large rivers like the Sacramento have not flooded over during this storm, other smaller rivers have seen some flooding, like the Cosumnes River near Elk Grove. This river, like many others in the state, has levees built around it to keep back flooding.

But as this storm has raged on, some of these levees have broken and failed to prevent overflow.

“Some of them have been built decades ago,” said Helen Dahlke, an associate professor in Integrated Hydrologic Sciences at UC Davis. “And we haven't really invested that much funding into upkeeping, just even checking the status of these levees, so there is definitely some aging infrastructure that could potentially become an issue.”


Elite Napa estates are releasing wines from a fire-ravaged year. Do they taste smoky?
(SF Chronicle) Esther Mobley, Jan. 1

… Smoke taint is a frustratingly opaque topic, still poorly understood by scientists. Basically, when smoke is in the air, certain compounds can make their way into grape skins. But what’s hard to grasp “is that it’s not a linear relationship,” said Anita Oberholster, a UC Davis scientist. “Just because somebody has smoke at their vineyard doesn’t mean they will have smoke taint.” Various factors like the land’s topography, the wind direction and the freshness of the smoke can determine the ultimate effect.

Confusingly, “proximity to fire is actually not a good indicator,” said Oberholster.

What if Indigenous women ran controlled burns?
(High Country News) B. ‘Toastie’ Oaster, Dec. 30

… The events spread the theory and practice of prescribed burning. But they are also a way to change mainstream fire culture, which has long been “very exclusive, very militaristic, very socially and culturally homogenous,” said Lenya Quinn-Davidson, fire advisor for the University of California Cooperative Extension and director of the Northern California Prescribed Fire Council. 

...Fire management is predominantly white and around 90% male, Quinn-Davidson said. So, to counterbalance the militaristic, hyper-masculine firefighting culture, she has hosted five women’s training exchanges since 2016. These aim to be 90% women, and participation demand is high.

‘The War on Drugs Part II’: California taxes, rules are killing small legal weed farms
(LA Times) Kevin Rector, Dec. 29

…In a book published this year titled, “Can Legal Weed Win? The Blunt Realities of Cannabis Economics,” UC Davis economists Robin Goldstein and Daniel Sumner outlined a number of headwinds faced by small legal cannabis farmers in places like Humboldt County.

Among the largest, they found, were the array of taxes and regulations that states like California have put in place for legal growers — despite knowing it would give their illegal competitors an advantage.

“Getting legally compliant means lots of fees; unknown, and almost always longer-than-expected, waiting periods; complex testing, tracking, packaging, and labeling requirements; and steep cannabis taxes,” Goldstein and Sumner wrote. “Illegal weed businesses do not face any of these costs or taxes, so they can run leaner, lower-cost operations and sell comparable products for lower prices than legal businesses can.”

California Chill Report: Researchers Look at Solutions to Dormancy Issues
(AgNetWest) Dec. 21

Mild winters in recent years have been creating some dormancy issues in orchards that become apparent later in the season. Researchers have been evaluating different options that might assist walnut growers to overcome some of those challenges. UC Cooperative Extension Orchard Systems Advisor for Yolo, Solano, and Sacramento counties, Kat Jarvis-Shean said they have been looking at a couple of different products in a multi-year study.

“With funding from the California Walnut Board for the first couple of years and now we just started getting funding from CDFA, we’ve been looking at dormancy breaking treatments that get applied in about a month before anticipated bud break,” said Jarvis-Shean. “To help wake the trees up so that we don’t see these weird behaviors that you usually get with low chill.”


Making a salad might be getting more expensive. Could climate change be to blame?
(LA Times) Alejandra Reyes-Velarde and Hayley Smith, Dec. 21

It was the two (INSV and Pythium wilt) in tandem that wiped out Salinas crops this fall, said Richard Smith, a researcher with the University of California’s Cooperative Extension program, which places agricultural advisers and researchers in local communities. While both have presented challenges to farmers in the past, something changed in the last few years to worsen the impact on lettuce crops.

“There had been these heat spells that we think have triggered the soil-borne disease,” Smith said. He wondered whether climate change may be a factor.

“That’s a question we have,” Smith said. “All you can do is kind of infer that possibly that’s part of the problem. But one thing is true. Those heat spells were unprecedented. Is that global warming? Who knows? Could be.”

$11 for a head of California lettuce? Here’s what’s behind the shortage causing ‘outrageous’ prices
(Mercury News) Ethan Varian, Dec. 16

Richard Smith, a vegetable researcher with the University of California Cooperative Extension in Monterey County, said INSV has been known since around 2006 and may have originated with flowering plants in greenhouses.

The reason it’s pummeling the Salinas Valley now, Smith said, is in large part because the region is already dealing with another crop disease called Pythium wilt, caused by fungi-like pathogens. The dual outbreaks came to a head this fall after spreading rapidly for most of the growing season, which just recently ended.

New study says California's farmland is shrinking due to years-long severe drought
(CBS Sacramento) Madisen Keavy, Nov. 28

…The last three years have been the driest in the instrumental record and the multi-year deficits in precipitation have been compounded by "increased crop evaporative demands" according to the report. Researchers on the report — which included authors from UC Merced, UC Davis, and the Public Policy Institute of California — found that the state's irrigated farmland shrunk by nearly 10% which totals 752,000 acres of farmland. 

… "Agriculture employs lots of people directly, and indirectly, I talk about the farm worker, but I could just as well talk about the people in the processing plant. There are tomato processing plants that just aren't going to employ people long into the year because it was a short crop," said Daniel Sumner, one of the report's authors and a professor of Agriculture Economics at UC Davis. 


The burn scars of the Sierra foothills tell a story – and offer lessons
(KQED) Danielle Venton, Nov. 28

Brandon Collins stands in front of what was recently a hillside of young trees, now burnt to blackened crisps by a wildfire. When these trees were alive, the trunks were barely the diameter of an arm or a calf. They now look like a crowd of knobby, emaciated skeletons. They are of no economic value and, unless replanted, risk becoming a field of brush rather than regrowing as a forest.

“I think about, if we go back in time, what could we have done differently to change the outcome?” asks Rob York, co-director of Berkeley Forests, which manages the study site. This area was clear-cut a few decades ago and left alone ever since. “It’s tricky, right? They’re vulnerable because they’re short trees. It doesn’t take a lot of fire intensity to cause a high-severity fire.”

'We got really lucky': Why California escaped another destructive fire season in 2022
(LA Times) Hayley Smith, Nov. 19

...Scott Stephens, a professor of fire science at UC Berkeley, said he gives Cal Fire and other state agencies credit for some of their programs.

“Some of the wildfires that started this year ran into some of their fuel treated areas, and they were able to make a stand in some of those areas more effectively,” he said. “That wasn’t the majority of fires by any means, but some ... actually reached these areas, and the proactive work I think is paying off in those regards.”

However, Stephens also noted that the state did not see any major dry lightning events this year, such as those that helped fuel hundreds of simultaneous fires in 2020 and 2021, and benefited from some rain. He said it’s important to stay vigilant, even in the face of improvements.

The plants themselves are still under pretty extreme water stress, and they’re still potentially quite flammable, even if it’s cold,” Moritz said. “If we see again no rain until really late in the season, we could have winter fires and have some real problems.”



Urban Farms Are Stepping Up Their Roles in Communities Nationwide
(Civil Eats) Rachel Surls, Nov. 10

“As I’ve chatted with farmers and walked through their fields, three themes have emerged. First, many, if not most, urban farms operate as nonprofit organizations, often on a shoestring budget, led by farmers who are powerfully committed to their communities. Second, urban farmers are deeply involved with provisioning food-insecure communities—and most have made significant pivots to offer free and low-cost food during the COVID-19 pandemic. And third, urban farms promote community building that goes far beyond feeding people. They have offered a place to gather and be in the company of others during what has often been a lonely, isolating time, as well as a spark of hope for the future. The farms below illustrate these themes in three very different cities.”

…Manning says wildfires are only the start, and that Kettle hopes to eventually model other environmental catastrophes worsened by climate change, like floods and wind from hurricanes.

That could be a challenge, says Max Moritz, an adjunct professor of wildfire dynamics at UC Santa Barbara. Natural disasters often act very differently from each other, and predicting them can depend a lot on the specific nature of local geographies.

Put simply, what works in California might not work anywhere else. “It’s not a given that the performance will be that great,” Moritz says.

The resolution focuses primarily on decline related to heightened bark beetle activity in several North Coast conifer species — but as detailed in a study from the UC Cooperative Extension (UCCE), larger outbreaks can occur because of combined factors including wildfire, drought, fire suppression, and poor forest management practices.

Supervisor John Haschak spearheaded work on this resolution, collaborating with UCCE, various stakeholders, and supervisors from Lake and Napa counties. Both those counties have also declared tree mortality emergencies....

...Haschak explained that here in Mendocino County, increased aridity and movement from wildfires has put inland ponderosa pines at more risk; on the coast, bishop pine forests have also seen significant decline from a multitude of possible factors including encroachment of pathogens and insects. UCCE Forest Supervisor Michael Jones said he has also seen stress on local redwood forests, Haschak relayed. 


Researchers share what they’ve learned in the aftermath of the Mosquito Fire
(Cap Radio News) Manola Secaira, Nov. 3

Spotted owls have nested in parts of Blodgett Forest for years, and there’s one in particular that researchers grew fond of. 

Rob York, co-director of Berkeley Forests, said he never called the owl by a particular name but researchers in the forest would generally refer to him as “the old, crusty guy” in the area. 

“I’ve been here at Blodgett for 20 years, and that owl has been at Blodgett for 20 years,” York said. “It’s like it became this friend of mine.”

The Mosquito Fire burned through a part of Blodgett that included the owl’s nest. Since then, no one has seen him. 


Commentary: How farmer-researcher ties help agriculture thrive
(AgAlert) Donald Bransford, Nov. 2

As California’s economy is poised to overtake Germany’s as the fourth largest in the world, I am reminded that research and innovation drive progress.

In California, we are fortunate to enjoy an abundance of healthy food and other agricultural products, even as new complications arise in the business of farming. It’s no coincidence that California is the nation’s top agricultural producer with more than 400 commodities. University of California Agriculture and Natural Resources researchers and the state’s farmers and ranchers have been working together for more than a century to innovate, and our research needs continue to grow to adapt to drought, wildfire, invasive pests and diseases, and other challenges.

He’s an Outspoken Defender of Meat. Industry Funds His Research, Files Show
(New York Times) Hiroko Tabuchi, Oct. 31

…According to internal University of California documents reviewed by The New York Times, Dr. [Frank] Mitloehner’s [the head of an agricultural research center at UC Davis] academic group, the Clear Center at UC Davis, receives almost all its funding from industry donations and coordinates with a major livestock lobby group on messaging campaigns.

…The Clear Center said in a statement that it discloses funding in line with University of California policy. The university deferred questions to the Clear Center.

…In written responses to detailed questions, Dr. Mitloehner said the livestock industry’s financial and other ties to his research center were instrumental to the center’s mission. “I cannot help the livestock sector reduce its environmental impact without working directly with its members,” he said.

Why Legal Weed Is Losing
(City Journal) Charles Fain Lehman, Oct. 31

…Can Legal Weed Win?, the new book by UC–Davis agricultural economists Robin Goldstein and Daniel Sumner, tries to answer that question. The pair have carefully watched the marijuana market since before legalization, and they provide an economic perspective accessible to the lay reader. While Can Legal Weed Win? is a useful corrective to optimism about the marijuana market, however, its commitment to certain tropes about the evils of drug enforcement blinds it to the basic problem of the pot market: nobody is stopping illegal businesses from operating.

One third of Sierra Nevada forest wiped out by drought and fires

(Earth.com) Andrei Ionescu, Oct. 30

…Fortunately, state and federal government agencies are currently starting to rethink old practices and invest in wildfire resilience and forest health, with over $1,000 million dedicated to safeguard these historical forests. However, according to J. Keith Gilless, the chair of the state board of forestry and fire protection, the task of reverting forests to what they used to be will need long-term planning and dedication.

“We need to be clear to the policymakers that this isn’t something you go into with a one-shot infusion of money and it’s solved. It’s something where you’ve committed to moving to a different kind of landscape level management, that lets us truly deal with the natural hazard of wildfires,” he concluded.


Greener grass with less water? New batch of water-saving grasses showing great promise

UC-Davis gets $6.2 million for strawberry breeding research
(Capital Press) Sierra Dawn McClain, Oct. 26

Against a backdrop of climate change and possible future restrictions on chemical use, UC-Davis leaders say this research is critically important.

"We need to have the technology so that we can deal with the challenges strawberries face around the world," said Steve Knapp, director of the Strawberry Breeding Center and professor in the Department of Plant Sciences. "Can we use genetic knowledge to change the DNA in a specific way to get the resistance we need?"

One priority within the research grant is to identify whether changing DNA molecules can improve disease resistance — and if so, what technologies would be needed to accomplish that.


Are Wildfires Offsetting Progress in Carbon Reduction?
(Governing) Carl Smith, Oct. 24

…This isn’t the first time equivalences between fire emissions and those caused by humans have been put forward, says Max Moritz, a wildfire specialist for the University of California’s Cooperative Extension based at U.C. Santa Barbara. In 2008, for example, California’s U.S. Rep. Kevin McCarthy claimed that fires produce more emissions than cars.

For those who study fire, this kind of talk lands as vilification of an essential natural process (if not timber industry messaging), Moritz says. He doesn’t deny the basic notion that more carbon in the atmosphere is not desirable but cautions that equating wildfires to fossil fuel emissions brushes over the nuances of forest ecosystems.

This one fact will completely change how you think about California wildfires
(San Francisco Chronicle) Claire Hao, Oct. 15

...Before the 1800s, when Europeans flooding into California outlawed fires set by Native Americans, at least 4.5 million acres — and sometimes up to 12 million acres — burned in California every year, according to UC Berkeley researchers.

That figure has only one modern equivalent: 2020. That year, California wildfires burned over 4.3 million acres — more than double the state’s previous record. One astonishing day in September, the sun never rose in the Bay Area’s skies, which instead glowed an eerie orange from smoke.

“2020 really shocked me because it was the first year ever that we actually approached 4 million acres; in fact, we reached it,” said UC Berkeley forest ecology expert Scott Stephens, the study’s author.

Logjam: The Supply Chain Problem That’s Keeping California From Preventing Catastrophic Wildfires on Private Land
(Bay Nature) Jane Braxton Little, Oct 11

After the federal Northwest Forest Plan was at last finalized in 1994 and as court-ordered policies took effect, federal timber harvest volumes began plummeting. By 2009 the total was 60 million board feet—3 percent of the peak of two billion board feet in 1988. Saws went silent across the West. “It was like turning off the spigot,” says Ryan Tompkins, a forester and natural resources adviser for UC Cooperative Extension in Plumas County.

…Federal policy not only had halted the use of the beneficial fires that cleanse forests of fuels; it was also contributing to their accumulation. Combined with a steadily warming climate, western forests were becoming a tinderbox. And with fewer mills to process these forest fuels, forest owners across the landscape were hamstrung. There was no room at the mill for their logs. Don’t blame the timber industry, says Tompkins: “Public land management policy created the framework that has resulted in our current conundrum.”

...It is recent catastrophic wildfires that have motivated many private forest owners to actively manage their forests, says Susie Kocher, a forester with UC’s Cooperative Extension in the central Sierra. She has spent years trying to convince people to do thinning. “I barely have to do that anymore. People get it,” she says. Still, without the infrastructure to process the trees they remove, it’s tough going. Few places are available for owners to take the woody materials they are removing. Most end up burning them in open piles, wasting potential end products and contributing to carbon emissions. “They’ve won the lottery if they can sell to a sawmill,” Kocher says.


California migration of millions of birds brings ‘unprecedented’ avian flu threat
(Guardian) Katharine Gammon, Oct. 10

…“The prediction is we’re going to be hammered in the next several months,” said Maurice Pitesky, who monitors and forecasts bird viruses at the University of California, Davis.

There are 144 known types of bird viruses, most of them mild. Just as human viruses do, they swirl around the world and pop up in different places.

This year’s flu, known as H5N1, came from Europe, scientists say. Since its first detection in the US in January, in a wild duck in North Carolina, the high-pathogenic virus has spread rapidly across the country. In California, the strain was first recognized in geese and pelicans in the Central Valley in July of this year. Since then, more than 10 counties in the state have documented cases.

“Geographically speaking, we’re dealing with something unprecedented,” Pitesky said. “It’s only going to speed up over the next couple of months.”


Deadly avian flu reaches California
(China Daily) Yinmeng Liu, Oct. 7

…The virus has been detected in 41 of 50 states in the United States. It has led to the depopulation or euthanasia of more than 47 million birds, said Maurice Pitesky, an associate professor in the poultry health and food safety epidemiology department at the University of California, Davis School of Veterinary Medicine.

"The current outbreak is about seven times the size geographically of that previous outbreak, and we're just about to enter fall migration when literally millions of birds will start moving into North America, into the United States, and a lot of them are likely to be carriers of that virus," he told China Daily.

California wells run dry as drought depletes groundwater
(Associated Press) Terry Chea, Oct. 5

California’s groundwater troubles come as local agencies seek to comply with the Sustainable Groundwater Management Act, which Gov. Jerry Brown signed in 2014 to prevent groundwater overpumping during the last drought. The law requires regional agencies to manage their aquifers sustainably by 2042.

Water experts believe the law will lead to more sustainable groundwater supplies over the next two decades, but the road will be bumpy. The Public Policy Institute of California estimates that about 500,000 acres (202,000 hectares) of agricultural land, about 10% of the current total, will have to come out of production over the next two decades.

“These communities are going to be impacted from drinking water supplies and loss of jobs,” said Isaya Kisekka, a groundwater expert at the University of California, Davis. “There’s a lot of migration of farmworkers as this land gets fallowed.”


Wildfires are getting worse. Can scientists save California’s forests from going up in smoke?
(LA Times) Alex Wigglesworth, Oct. 4

This patch of woodland in the northern Sierra Nevada looks idyllic. Dappled sunlight filters through the lush branches of towering pines. Spaces between their slender trunks are thick with saplings.

But forest ecologist Robert York sees danger lurking in this portion of the UC Berkeley research forest.

The control plot has grown unmolested since the 1930s, when a timber company turned the land over to the university. It is now teeming with young cedars and firs — conifer species that tolerate crowded and shady conditions, but are more vulnerable to fire and drought.

Pockets of dead pines are forming as trees compete for water, weakening their resistance to pathogens and bark beetles.

“We have different metrics for describing why the fire hazard is high here,” York said. “But basically the gist is: There’s a lot of fuel on the ground and there’s a lot of trees here.”

Most of California’s forests — especially the 57% managed by the federal government — look somewhat like this, said Berkeley Forests co-director Scott Stephens.


California drought pits farmers vs. cities. But neither is the biggest water victim
(LA Times) Hayley Smith, Oct. 3

The consumptive nature of agriculture is the same reason why outdoor watering is among the first cuts to be made in urban areas, where an estimated 44% of water goes toward irrigating lawns and other uses outside the home. In Southern California, for example, officials this summer limited millions of residents to one- or two-day-a-week outdoor watering and saw a significant reduction in demand as a result.

But the total volume of water is only one metric for considering agriculture’s share, according to Isaya Kisekka, a professor of agricultural water management at UC Davis. Instead, he said, the best way of looking at water use is to look at nutritional water productivity, or how much protein, nutrients and calories are produced by a unit of water.

Farmers also consider economic water productivity — or how much economic value is produced by that unit of water — which “has been increasing in the state for a few years now,” he said. “That’s when crops like almonds, pistachios, grapes come into play, and that’s why you’ve seen a lot of growers shift to these crops, because they have very high economic water productivity.”

Bird flu spreads to Southern California, infecting chickens, wild birds and other animals
(LA Times) Susanne Rust, Oct. 3

“Unfortunately, we’re really just at the beginning” of this highly pathogenic avian influenza outbreak, said Dr. Maurice Pitesky, an expert in poultry health and food safety epidemiology at UC Davis. He noted that millions of birds are just beginning their southward migration from summer feeding grounds in the Arctic — a place where they’ve been mingling and communing with species from across the globe.

“Some disease models show that we are going to get hammered this fall,” Pitesky said, noting it could add stresses to the food supply, which is already being clobbered by high corn and soy prices — the food required to keep the millions of chickens and turkeys in poultry farms alive.

Is Natural Wine Actually Better for You?

…“There’s a wide perception that when you’re drinking something cleaner, you’re drinking something healthier,” said Anita Oberholster, a grape and wine industry expert at the University of California, Davis. But, she said, “there’s no clear proof of that.”

…“There wouldn’t be any significant difference in microbial content whether it was so-called natural wine or not,” said Dr. [David] Mills [a molecular biologist and distinguished professor in the food science & technology and viticulture & enology departments at UC Davis], who was skeptical of significant gut health benefits from drinking any type of wine. “The alcohol is going to kill most beneficial bacteria anyway, so it’s not like wine is ever going to have anywhere near the level of kimchi or yogurt.”


Coyote Interactions Remain A Huge Problem For Southern California. Why And What Can We Do About It? 
(KPCC) Larry Mantle, Sept. 21

Coyote human interactions have long been an issue in Southern California and tensions over how to manage it only seem to be growing. Attacks on pet dogs, missing cats, and an attack of a 2-year-old near the Huntington Beach pier in May, are just some examples of why residents are saying enough is enough. Some cities, like Torrance and San Dimas, have turned to trapping and euthanizing coyotes as their management plan. Others encourage co-existing and hazing, which are behaviors to deter the animal away from the area. And some experts say we really don’t know the best way to manage urban coyotes. Joining to discuss why that is and how we should move forward is Niamh Quinn, human wildlife interactions advisor with the University of California’s division of Agriculture and Natural Resources.

Inside the war against Southern California’s urban coyotes. ‘Horrific’ or misunderstood?
(LA Times) Louis Sahagún, Sept. 20

“If you have green spaces in your city, you have coyotes,” said Niamh Quinn, one of a small number of researchers who track and study urban coyotes. “In fact, you could probably find coyotes making nighttime visits at almost every schoolyard in L.A. County.”

Despite their ubiquity, the size of the coyote population in L.A. County remains unknown. (The state Department of Fish and Wildlife estimates that there are 250,000 to 750,000 coyotes statewide.)

Quinn, UC Cooperative Extension’s human-wildlife interactions advisor, has learned a lot about urban coyotes by following the GPS pings of collared animals.

“Urban coyotes really are different than coyotes in wilderness areas,” she said. “I doubt an urban coyote would survive very long in the wilds.”

California Today: California’s Largest 2022 Wildfire Puts U.C. Research to the Test
(New York Times) Raymond Zhong, Sept. 16

…This spring, I traveled to Blodgett Forest Research Station, which is owned by University of California, Berkeley, to watch scientists conduct a prescribed burn. These controlled, low-intensity fires rob wildfires of the small trees, dead vegetation and other fuels that can turn them into catastrophic infernos. And as I wrote in The New York Times last week, researchers are using high-tech tools to figure out how we can burn more safely and effectively as climate change makes prescribed burning trickier.

So when the Mosquito fire entered Blodgett last Friday, Robert York, a Berkeley forest ecologist, saw it as a test of the methods for controlling fire behavior that he and other scientists have been studying for decades.

“I’ve worked for the last 20 years for this moment,” York told me by phone from Garden Valley in El Dorado County, where he is staying with friends after evacuating from his home in Georgetown, a short drive from Blodgett. “Here’s an actual real-life test. It’s not just computer models.”


Small farmers bear an extra burden as California agricultural policies respond to a changing climate

Dr. Ruth Dahlquist-Willard, the Small Farms and Specialty Crop Advisor with the University of California Small Farms Extension, works with many different immigrant farmers. 

She focuses on small communities of farmers, including Hmong, Lao, and Vietnamese refugees who fled conflict in their home countries in the decades after the Vietnam War and carved out a market selling culturally relevant foods, such as bok choy and lemongrass, to other immigrants living in the area. 

Dahlquist-Willard also works with Latino and African-American farmers. Many of the Latino farmers in particular are attempting to make the same transition that the Masumoto family made: from farmworker to farm owner.

Forest Service resumes prescribed fire program, but some fear new rules will delay projects
(LA Times) Alex Wigglesworth, Sept. 13

…Although it seems counterintuitive, the escape actually demonstrated the need for agencies and partners to put more fire on the landscape, said Lenya Quinn-Davidson, area fire advisor for the University of California Cooperative Extension.

“It’s not just about how that fire started but the condition of the landscape it was burning in, the fact it had no fire history in the last 100 years or so,” she said. “It was this very homogenous forest that didn’t have patchy patterns of recent fire like we would want to see.”

The Forest Service says its prescribed fire program has a 99.84% success rate. Of the 0.16% of burns that do escape control, even fewer cause damage, said Quinn-Davidson, who is also the director of the Northern California Prescribed Fire Council.

“Why are we spending so much time focused on the things that go wrong when almost 100% of the time it goes right?” she said.


Opportunities for Northstate women in the fire industry
(KRCR) Anna Montemor, Sept. 13

...Northern California Prescribed Fire Council Director Lenya Quinn-Davidson says firefighting is a lot like the military, where women hold a very small portion of the fire workforce.

She added, this can be discouraging for women and minorities who have thought about pursuing the career before. So much so, they don't try at all.


How climate change is tweaking the taste of wine
(BBC) Ula Chrobak and Katarina Zimmer, Sept. 11

Soon after the devastating Glass Fire sparked in California's Napa Valley in September 2020, wine chemist Anita Oberholster's inbox was brimming with hundreds of emails from panicked viticulturists. They wanted to know if they could harvest their grapes without a dreaded effect on their wine: the odious ashtray flavour known as smoke taint.?

The rice capital of California is ‘now just a wasteland.’ Satellite images show how bad it is
(SF Chronicle) Yoohyun Jung, Sept. 10

…The dramatic reduction in rice acreage will translate to lost revenue of an estimated $500 million, about 40% of which will be covered by federal crop insurance, according to UC Davis agricultural economist Aaron Smith.

… “The difference is the source of water,” said Luis Espino, a farm advisor at UC ANR’s cooperative extension in Butte. Eastside farmers depend on Lake Oroville, which was able to capture more water than Shasta Lake, where the current storage is less than half of the average storage for this time of year.

… “Rice will likely rebound again once this drought ends, but this year’s massive reduction feels like a harbinger of tough times ahead for California rice,” Smith, the UC Davis agricultural economist wrote in his August analysis.

Column: Has a UC Riverside researcher created the Holy Grail of drought-tolerant lawns?
(LA Times) Gustavo Arellano, Sept. 9

The cheerleader for Public Enemy No. 1 greeted me at the gates to UC Riverside’s Agricultural Experiment Station with a smile and some choice words.

“Every time there’s a serious droughtI’m in the L.A. Times,” Jim Baird said, only half-jokingly. “Why is it always a knee-jerk reaction? When it’s not a drought, I don’t hear from you guys. I don’t hear from the water agencies. Then we go through our wasteful ways. ‘Lawns, you’re the bad guys,’ everyone then says.”

The tall, skinny, loquacious Baird is the head of UC Riverside’s Turfgrass Research & Extension program, devoted to the study of growing and maintaining lawns. He’s the only such faculty member in the University of California system, which makes him the state’s Mark Twain of turf. Our LeBron of lawns. The Ira Glass … of grass.


Biopesticides to manage Pierce's disease trialed at UC Davis
(Wine Business) Ted Rieger, Sept. 8

A field day held September 6 at the University of California Davis (UCD) provided preliminary findings from the first year of a three-year research field trial funded by the California Department of Food & Agriculture Pierce's Disease/Glassy-winged Sharpshooter Board to evaluate four biopesticides to manage Pierce's Disease (PD) in grapevines.

Biopesticides, naturally occurring microbial organisms able to combat and control harmful pathogens in plants, are a focus of research by UC Cooperative Extension plant pathologist Akif Eskalen and his lab in the UCD Department of Plant Pathology. Eskalen has conducted field trials for several years to evaluate potential biopesticides for use as pruning wound protectants to prevent and manage grapevine trunk diseases.


California’s week of heat and wildfires foretell a punishing autumn
(The Guardian) Gabrielle Canon, Sept. 7

It was an explosive Labor Day across California, as an intense, days-long heatwave smashed temperature records, spurred the spread of deadly and destructive wildfires, and bathed cities in a stifling heat even long after the sun went down.

The events mark a grueling start of what traditionally make up the highest fire-risk months in the west, with experts bracing for a higher potential of a punishing autumn even after a milder-than-expected summer.

“Having this heatwave in California and the extreme temperatures we are facing across the west right now – the conditions are just so primed for fire activity,” said Lenya N Quinn-Davidson, an area fire advisor for the University of California Cooperative Extension.


Industry needs will guide UC Organic Agriculture Institute efforts
(AgNet West) Brian German, Sept. 7

Back in 2020, the University of California announced the establishment of a UC Organic Agriculture Institute. The purpose of the institute is to develop a resource specifically for the organic sector. Director of the Institute, Houston Wilson said that much of the work thus far has been garnering a better understanding of the current organic landscape in the state.

“One of the starting points was to develop a proposal for a needs assessment at the state level. This was something that we put to the USDA Organic Agriculture Research and Extension Initiative, and it was successfully funded,” Wilson explained.


Effects of drought, freeze on the minds of Colusa Co. farmers
(Appeal-Democrat, via Yahoo) Lynzie Lowe, Sept. 7

Franz Niederholzer, University of California Cooperative Extension farm advisor for Colusa, Sutter and Yuba counties and UCCE County director for Colusa County, said the record cold experienced in the region on Feb. 24 and surrounding days caused potentially widespread damage to area almond crops, also severely affecting crop production within Colusa County.

Colusa County officials said this freeze ultimately resulted in a 74% loss of local almond crops, with an estimated direct financial loss to growers of nearly $210 million.

…"We are forward thinkers the researchers and industry working together, and we're thinking of ways to control the environment as much as we can," said Dr. Anita Oberholster, an expert in Viticulture and Enology at UC Davis.

…Layers of leaves as well as artificial shades canopy the fruit in an attempt to keep clusters cooler. The canopies can drop the temperatures dramatically and provide relief to the fruit.

"What it also provides is that it lessens the amount being evaporated from the soil and from the vineyard," explained Dr. Kaan Kurtural, who also specializes in viticulture and enology at UC Davis.

Citrus risks unclear from virus ID'd in Tulare
(Bakersfield Californian) John Cox, Aug. 28

The hope is it's not as worrisome as citrus greening disease, or Huanglongbing, or HLB, a devastating bacterial infection for which no commercial treatment exists. Its winged vector, the Asian citrus psyllid, has been found in the Central Valley but the disease itself has not been detected north of the Grapevine.

"I don't think it's going to be as bad" as HLB, said Greg Douhan, a citrus adviser with the University of California Cooperative Extension program in Tulare County. He noted growers in the area use pesticides that seem to control the virus' vectors.


California’s extreme wildfires taking lethal toll on elderly who can’t escape flames
(LA Times) Alex Wigglesworth, Aug. 26

“Whenever there’s a thunderstorm around an existing fire, it’s very dangerous, because you get these updrafts and downdrafts from the thunderstorm itself, and you can generate really, really sporadic high-velocity winds,” said Scott Stephens, a professor of fire science at UC Berkeley. “And I think that’s one of the reasons why, unfortunately, four people got caught.”

And there were other factors, he said, including the combination of extreme drought conditions and overgrown vegetation that can make it easy for embers to ignite and spread. A history of logging and fire-suppression policies has also resulted in stands of unnaturally young, dense timber that is more susceptible to fast-moving crown fires, according to experts.

“The legacy of both removing Indigenous burning and also fire suppression have really set these forests up for catastrophic change,” Stephens said.


Most Californians view state’s water shortage as extremely serious, poll finds
(LA Times) Ian James, Aug. 25

…The results indicate that people in farming areas have been feeling the effects of shortages more than those in other parts of the state, said Faith Kearns, a scientist with the California Institute for Water Resources.

“My sense is probably that in urban areas, people are largely buffered, even though in some regions, people have been asked to reduce their landscaping water and things like that,” Kearns said. “But I think for most people, when they go to turn on the tap, the water still comes out. And so they aren’t as deeply affected by it, if you’re not in an area where you’re seeing the effects of water shortage every day.”

California’s timber industry is calling on the military to help control fires
(The Washington Post) Anna Phillips, Aug. 23

Lenya Quinn-Davidson, a fire adviser with the University of California Cooperative Extension, said she sympathizes with the industry, but she doesn’t think bringing in more people will save the state’s forests. Fast-moving wildfires like the recent McKinney Fire and last summer’s Dixie Fire can’t be fought, she said, but prescribed burns and thinning might make them less severe.

“There’s this notion that if we just had more people, we could get a handle on putting the fires out,” Quinn-Davidson said. “But the conditions out on the landscape are beyond our ability to control them. The answer is really in the proactive work in the offseason.”


Why grasshoppers are the newest problem plaguing California farmers
(KXTV) Brody Adams, Aug. 23

...Grasshoppers can consume up to 250% of their body weight daily and 30 pounds of the insects consume the same forage as a 600-pound steer, according to farm advisor Tom Getts of the University of California Cooperative Extension. 

..."Once they have wings, they've been shown to move, you know, 10 to 20 miles to search for food. And they really have had a devastating impact, where people have had the water to grow hay, because there hasn't been much on the range lands for them to eat," Getts said.


To fight wildfire, California gets a surprising solution: A new sawmill
(Bloomberg, via Yahoo) Laura Bliss, Aug. 22

The silencing of chainsaws was the sound of victory for environmental activists and forest ecologists, even a few years ago. And no one wants to see the type of clear-cutting that destroyed old-growth forests for much of the 20th century. But now scientific consensus is shifting towards acceptance — and even encouragement — of a certain amount of logging.

“There's just such abundant evidence that if we do nothing, we’re going to lose it all,” said John Battles, a professor of forest ecology at the University of California at Berkeley. “The forests will suffer such severe losses that we’re no longer protecting the species. We’re putting them at risk.”


California drought: Why more than 530,000 acres of farmlands are now left barren
(SF Chronicle) Yoohyun Jung, Aug. 22

The years-long drought and dwindling water supply are estimated to have left more than 531,000 acres of California farmlands unplanted without harvest this year — a 36% increase since August of last year.

The new estimates on acres farmed from the U.S. Department of Agriculture (USDA) reflect the struggles of some California farmers to procure water to irrigate their crops as major government water projects supplying their water remain thirsty as drought continues for a third year.

“It’s true that things are not great now,” Aaron Smith, professor of agricultural economics at UC Davis, said. The crops that are likely most affected by water shortages are water-intensive field crops, such as rice and cotton, which have been declining in the state.


Avian bird flu in Butte County called local health emergency after 1,500 birds exposed
(CBS Sacramento) Brady Halbleib, Aug. 19

Avian Flu usually stems from wild birds like ducks and geese. However, the disease can transmit quickly through shared environments. 

"Right now, which is unique, we have a pathogenic strain that seems to be circulating in waterfowl and other wild birds," professor of Poultry Health and Food Safety, Dr. Maurice Pitesky said. "It's really important to do the best you can to prevent that virus from moving into your flock, infecting your flock, and then potentially spreading to another flock."


Are indoor vertical farms really ‘future-proofing agriculture’?
(The Guardian) Victoria Namkung, Aug. 18

...Gail Taylor, the department chair of plant sciences at the University of California, Davis, said that while vertical farming is energy intensive in its current form, so is traditional outdoor farming.

“Sometimes we forget all the consequential effects like how many times you drive a tractor over a field or how many trucks you use to bring lettuce from the west coast to the east coast and fly food all around the world,” Taylor said.

...And while some farmers and scientists are critical about the influx of capital into the vertical and greenhouse farming space, saying indoor-grown food isn’t necessarily better for people or the environment, Taylor said it doesn’t need to be an either/or proposition.

“[Indoor farms] are never going to replace outdoor agriculture,” she said, “they’re only going to enhance it and make food supply systems better for the world.”


Customers mourn after Fresno County produce stand shuts down for good
(KFSN) Alyssa Flores, Aug. 15

The family that runs the stand tells Action News that not having the lease renewed for their farm and stand was only part of the reason they were forced to shut down.

Lilian Thaoxaochay is familiar with the challenges the Saeterns and other strawberry growers face. She's a small farms community educator through the UC Cooperative extension.

"Fresno strawberry growers don't grow for commercial production, it stays completely local and they pick daily," Thaoxaochay says.

..."When we only get our food at the grocery store, I think what we lose is the connection between the people who eat the food and the people who grow the food," says Ruth Dahlquist-Willard with the UC Cooperative Extension.


Turkestan cockroaches, invading California, already ‘all over the Bay Area’
(San Francisco Chronicle) Michael Cabanatuan, Aug. 13

...(Chris) Grinter and Lynn Kimsey, an entomology professor and director of the Bohart Museum of Entomology at UC Davis, agree that the spread of the Turkestan roach is no cause for alarm. They aren’t a danger to humans, plants or animals, and prefer to live outdoors.

“People need to not panic,” she said. “They’re absolutely harmless.”

...Turkestan cockroaches are flat, long insects with antennae and wings. Females are about an inch long and dark brown to black with cream-colored markings along the edges behind the head and wings, according to the University of California’s Integrated Pest Management Program. Males are slightly smaller with yellowish-tan wings and cream-colored stripes along the edges.


UC Davis plant research could save farmers billions of dollars while fighting climate change
(KCRA) Heather Waldman, Aug. 12

Despite the steep cost, fertilizer is a necessary expense for farmers in order to ensure that their crops produce enough food to feed growing demand. But nitrogen fertilizers also pose significant environmental threats.

"The problem is more than half of whatever we are putting on the soil leaches out and goes to our water sources," Eduardo Blumwald, a distinguished professor of plant science at UC Davis, said.

That can lead to contaminated drinking water, excessive plant and algae growth and even increased greenhouse gases.

LA Explained: How to swap out your thirsty lawn with drought-friendly plants
(LAist/KPCC) Caitlin Hernández, Aug. 2

Janet Hartin is an environmental horticulture advisor at the University of California’s Agriculture and Natural Resource. For comparison, she says some cool-season turf can need about 30% more water than Bermuda grass.

“I will say that our warm-season grasses — it’s not that they're not drought efficient,” Hartin says. “It’s the method of watering in which we have water running down our streets and sidewalks.”

That’s why many rebate programs that pay you to take out your turf require a more water-efficient system instead of sprinklers, like drip irrigation.

With two supervisors dissenting, the Mendocino County Board of Supervisors approved further work on developing a countywide water resource team in collaboration with the University of California Cooperative Extension on Tuesday morning. 

…First district Supervisor and Vice-Chair Glenn McGourty drafted a plan which the board approved in a “conceptual” capacity, with caveats. He proposed a collaborative effort between existing county staff across departments to “provide expertise, write grants and administer programs”; and a Water Resource Specialist to work from the UCCE offices, organize the in-house team across multiple county departments, liaise with an outlined list of UCCE experts, maintain a database of Mendocino County water needs, and find resources to address them. The county would hire for that position — and that person would also serve as the staff point person for the Drought Emergency Ad Hoc Committee and the contact person for State Water Resource Agencies, he outlined in his presentation.

Op-ed: Why forest managers need to team up with Indigenous fire practitioners
(LA Times) Don Hankins, Scott Stephens and Sara A. Clark, July 31

Indigenous practitioners have long known that these place-based fire and land stewardship practices encourage the growth of food and useful plants and offer community protection. More recently, scientists from across the West have realized the effectiveness and necessity of using these practices to build resiliency, even as the climate changes. Public agencies such as the Forest Service and Park Service now manage some wildfires similarly, but only when fires are away from infrastructure and private lands. Consensus is emerging that these practices (cultural burns, prescribed fire and managed wildfire) are critical tools to address wildfire risk and forest health across the West.

We have recently convened a partnership of scientists and Indigenous leaders from across the Western states to advocate for the kinds of policy solutions necessary to build beneficial relations between people and the land and to restore resilience to our ecosystems. We call for change by federal and state policymakers, land managers and fire agencies in four main areas.

Eco-tip: Comparing ways to cut landscape watering
(Ventura County Star) David Goldstein, July 31

Compost is better for adding nutrients and improving soil structure if mixed into the soil during planting. Shredded woody material is better if your garden is already in place and you want a top dressing. It conserves water by shading the ground, cutting soil temperatures, reducing evaporation and suppressing weeds.

Spreading compost on the surface can easily invite weeds that rob water from desired plantings, said Ben Faber, a University of California Cooperative Extension Farm Advisor in Ventura....

California’s strawberry fields may not be forever. Could robots help?
(LA Times) Sam Dean, July 26

Mark Bolda, the director of the University of California’s Santa Cruz County Cooperative Extension and a berry specialist, agrees that California strawberries face a number of challenges — but is skeptical that the economics for tabletop farms picked by robots add up, or that the state’s industry is going anywhere.

Tabletop adoption so far has been limited, Bolda said, though he has seen experimentation. With the new fumigant regime, he said, “it’s getting iffy and we’re starting to see a lot more disease, so larger companies are trying to grow their competence in tabletops, but not at scale.”


California wildfires are in better shape than this time last year, but that may not last
(KTVU) Tom Vacar, July 26

Wildfire seasons are 40 to 80 days longer today on average, than back in the early 1990s. "Thirty years, we've also seen forest conditions deteriorate," said internationally renowned Dr. Scott Stephens, Director of the UC Berkeley Wildfire Lab.

What’s happening? "Forest conditions have also gotten worse because of no fire, no respiration thinning and cumulative impacts," said Dr. Stephens. No doubt, jumping on all fires ASAP in the short-term abates wildfire. "I think Cal Fire, to their credit, is trying to do this as best they can," said Stephens.

Imagine this: it’s 2050. Fire regimes are intact and flourishing across the United States. Coastal prairies and mountain meadows are teeming with grasses and flowers, and forests are open and healthy, with scattered clusters of old and young trees. Stream flows have increased, even during extreme drought, because frequent fire has released so much water from the clutches of dense, fire suppressed vegetation. The rivers are full of fish, the oak woodlands humming with birds, butterflies, and other wildlife. 


Addressing California Red Scale in the San Joaquin Valley
(AgNet West) Brian German, July 19

Citrus producers are working to address California red scale populations, as second-generation crawlers have emerged in the San Joaquin Valley. Cooperative Extension Area Citrus IPM Advisor, Sandipa Gautam said their tool for tracking degree days in Kern, Tulare, Fresno, and Madera counties can be a helpful resource for growers. Gautam explained that the hot and dry conditions are exceptionally conducive for red scale populations and that it is everywhere at the Lindcove Research and Extension Center.

“In the last weeks, we have had enough degree days accumulated for the crawlers to complete development and hatch,” said Gautam. “We have crawlers and whitecaps right now and because they are at the most susceptible life stage to insecticide applications, this is the perfect timing to make a spray application if you have red scale in your block.”

How three California women are working to change the way the state responds to wildfires
(CapRadio) Megan Manata, Vicki Gonzales, July 16

… Susie Kocher, a forestry advisor with UC Cooperative Extension in South Lake Tahoe, instructs private landowners in her region on how to do controlled burns.

She said that over the past four years they offered training in the Sierra Nevada and had about 33 workshop days with a total of 1,000 people that have attended. Kocher said that previously there’s really been no place for people to learn these skills before her group started workshops.

“If you’re an individual, you can’t really go to an agency burning class,” Kocher said. “So really, these events need to be structured around landowners' needs and locations where they can take part.”

Lenya Quinn-Davidson, fire advisor with the University of California Cooperative Extension, explained that fire is a really important process in the natural habitat of the state.

“Most California exosystems are either fire adapted … or they’re fire dependent, meaning that they actually require fire in some way to persist on the landscape,” Quinn-Davidson said. “So when we look around anywhere you are in California, that landscape is going to have a fire story to tell, and it’s up to us to figure out what that is.”

Yosemite’s Washburn Fire won't be the last time wildfires threaten California’s giant sequoias
(CapRadio) Manolo Secaira, July 14

…Brandon Collins, lead scientist for UC Berkeley’s research forests, says that the century of fire suppression has allowed for growth in the park that would have been unlikely under natural conditions. He uses the California incense-cedar as one example of a tree that’s been allowed to grow larger than usual due to fire suppression. In some cases, he says these trees have grown up to 30 inches in diameter, making them difficult to cull during prescribed burning. 

“Yet that tree, under wildfire conditions, can be a vector to spread fire from the surface up into the crowns of the really large sequoias,” he says.

Collins says that he sees a future where the cutting of trees, like these large California incense-cedars, might be necessary.

Can we hack DNA in plants to help fight climate change?
(National Geographic) Madeleine Stone, July 13

To boost carbon sequestration in croplands...some of that extra carbon needs to get below ground. In parallel research led by crop geneticist Pamela Ronald at the University of California, Davis, researchers will screen a library of 3,200 mutant strains of rice housed at the IGI for varieties with beneficial root traits....Once Ronald and her colleagues have identified rice strains with interesting root traits, they hope to use CRISPR genome editing to further optimize those traits....

...On the biology side, UC Berkeley microbial ecologist Jill Banfield and her colleagues will use genomic sequencing tools to investigate the specific microbes and carbon cycling traits in the soil surrounding CRISPR-edited crops. Banfield says she’s particularly interested in looking for microbial species that, like plants, use carbon dioxide directly to create their own food, and ones that produce extracellular polysaccharides—sticky, sugary substances that act like glue, enhancing the formation of carbon-trapping soil aggregates. 


A case for retreat in the age of fire
(The Conversation) Emily Schlickman, Brett Milligan & Stephen Wheeler, July 13

...It has been nearly four years since the Camp Fire, but the population of Paradise is now less than 30% of what it once was. This makes Paradise one of the first documented cases of voluntary retreat in the face of wildfire risk. And while the notion of wildfire retreat is controversial, politically fraught and not yet endorsed by the general public, as experts in urban planning and environmental design, we believe the necessity for retreat will become increasingly unavoidable....


Mapping a State's Secret Water
(Sierra) Isobel Whitcomb, July 13

… This tale of extremes is California’s new normal, says Graham Fogg, a hydrogeologist at the University of California, Davis. To survive this climate-changed future, the state needs to capture those torrents—and the tools to do so are right beneath our feet. In California, hidden under the ground are aquifers that have the capacity to store an estimated 1.3 billion acre-feet of water—26 times all of the state’s reservoirs combined. All California needs to do is guide the floods caused by torrential rainfall into the ground, instead of out to sea. “If we just capture the upper 5 to 10 percent of flood flows, that is enough water to compensate for the loss of water due to climate change,” says Fogg.

…Thousands of trees are dying in Napa County, said Michael Jones, a forest adviser for the University of California Cooperative Extension. The numbers will reach the tens of thousands before the infestation runs its course.

… Jones had suggestions for the short term. He recommended removing declining trees to reduce the beetle population, removing and destroying beetle-infested materials and removing dead trees that could help fuel wildfires.


Women in fire restoration
(Capitol Radio Insight) Vicki Gonzalez, July 11

As wildfire season ramps up in California, there is a growing push to change the decades-long mindset of fire suppression which has led to dense areas of vegetation. That, coupled with climate change and drought, has contributed to extreme fire risk across the state. The conversation and funding are shifting to change the way we live with fire, which includes reintroducing a long-overdue relationship with prescribed burns to manage forests and reduce mega-record wildfires in recent years. Joining Insight are leading experts in forestry management from the Bay Area to the North Coast and central Sierra. All women in a field that historically has been overwhelmingly male and white. Dr. Sasha Berleman is the director of the Fire Forward Program at the non-profit Audubon Canyon Ranch based in the Bay Area and is the first graduate of the state’s “burn boss” program. Lenya Quinn-Davidson is a Fire Advisor with the “University of California Cooperative Extension” in Humboldt County. Susie Kocher is a Forestry Advisor also with the University of California Cooperative Extension based in South Lake Tahoe. 


Foothill farm advisor to retire after 22 years
(Placerville Mountain-Democrat) Mike Hsu, July 11

Serving Amador, Calaveras, El Dorado and Tuolumne counties, UC Cooperative Extension advisor Lynn Wunderlich was formally assigned to focus on viticulture and integrated pest management in the region. But her innate curiosity – as well as her dedication to meeting the wide-ranging needs of local communities – led her to develop expertise in a remarkable array of topics.

“That was both the challenge and the opportunity of being a foothill farm advisor – lots of small farms, lots of diverse agriculture, so I got to do some cool things,” said Wunderlich, who is set to retire on July 1. “To serve the needs of the clientele up here was very gratifying and interesting.”

Ecologists say federal wildfire plans are dangerously out of step with climate change
(NPR) Eric Westervelt, July 3

"We all know federal agency agencies turn at the speed of an aircraft carrier, they're just incredibly slow," fire expert Barbara Satink-Wolfson says. "Yes, we have to be patient. But at the same time, we're all impatient because we know that we really need to make this change quickly."

...In an open letter to Chief Moore, dozens of forest experts with the Association for Fire Ecology recently urged him to reverse course and not make intentional burn pause nationwide. Doing so, they argued, will only make fire conditions worse in places that are not too dry to burn.

"There's basically a small window in which they can conduct the prescribed burn," says Satink-Wolfson, one of the letter signers and a fire adviser with the University of California Cooperative Extension on the Central Coast. "I think other places in the country could have continued. And we definitely missed opportunities."


Eco-tip: Not all lawns will survive under local watering limits
(Ventura County Star) David Goldstein, July 3

Consequently, one local drought response measure will likely be widespread browning or replacement of lawns.

Indeed, some lawns in Ventura County will not just go dormant; they will die, according to Jim Downer, a UC Cooperative Extension farm advisor in Ventura who specializes in turf grass.

Downer, like most scientists, provided several caveats. As detailed in his blog, The Garden Professors, some types of turf grass can endure water deprivation better than others. Warm-season grasses, including bermudagrass, St. Augustinegrass and kikuyu grass can survive conditions that would kill cool-season grasses, such as Kentucky bluegrass, ryegrass and tall fescue.

Cal Fire fumbles key responsibilities to prevent catastrophic wildfires despite historic budget
(KQED/The California Newsroom) Scott Rodd and Danielle Venton, June 21

...currently, Cal Fire does not have a way to track work completed by many private landowners.

"It highlights something pretty basic, which is we need an accounting system that works," said Max Moritz, a wildfire specialist with University of California Cooperative Extension.

He notes that tabulating total fire mitigation acres is a limited method of measuring risk reduction. He and other experts advocate for a system that takes into consideration factors like proximity to vulnerable communities and topography. But quantifying total acres of completed work is a basic step toward a more sophisticated assessment system, according to Moritz.

...In a legislative oversight hearing last December, Lenya Quinn-Davidson — a fire adviser with the University of California who helped write the legislation and the curriculum and who hosted the first course — told lawmakers:

"We've missed a ton of opportunities for project implementation. There is a huge need for qualified burn bosses to plan and implement projects and to partner with the state and to partner with landowners. But without the state certification and the protections that it can provide, many of those folks are not willing to go out and do that work."

Quinn-Davidson wrote a blog post in mid-January about the delays in the certification process. Soon after it published, Cal Fire issued task books to almost all participants, according to a blog update. Will Harling confirmed receiving his.

"We need to see this work happen more quickly," Quinn-Davidson told The California Newsroom.


California has a drought and 4 million acres of lawns. Should state ban grass to save water?
(Sac Bee) Ryan Sabalow and Dale Kasler, June 19

Jim Baird, a University of California Cooperative Extension specialist in turfgrass management, listed a litany of reasons to keep lawns. He cited their benefits to “property values, mental health, erosion control, groundwater recharge and surface water quality, organic chemical decomposition, carbon sequestration, and environmental cooling.”

“Irrigating lawns is not rocket science,” Baird said in an email. “We need to educate Californians on the proper (grass) species to use, as well as irrigation technology and practices. Turfgrasses don’t waste water. People and faulty irrigation systems waste water.”


Project diverting exhaust into orchard looks to improve farming efficiencies

…Mites, small arachnids or 8-legged arthropods, are found in thousands of different species, according to acarologists — scientists who study them — and David Haviland, Farm Advisor at UC Davis is one of those scientists.

…“Some felt there were too many mites compared to the numbers of beneficials who preyed on them, so they sprayed and things are great,” Haviland says. “We’re in that period when mites have gone away and growers may wait to spray again until hull split or a little after that when mites start showing up again to make their late season appearance.”

Will electric trucks work on the farm?
(Farm Press) Tim Hearden, June 9

Sarah Light, a University of California Cooperative Extension agronomy field advisor, says she has talked to growers about electric tractors but not trucks. She says she’s “pro-EV,” but understands it can be hard to charge the vehicles in rural areas. Charging can be fast – about 45 minutes – but you must find a charging station, and many are on main highways, she said in an email.

“Are growers and PCA’s (pest control advisors) driving on the highway or doing long miles on rural roads from field to field? Are there EV stations in those rural communities or only ones on (Interstate) 5? In the busy season, is a grower going to drive 30 minutes out of their way to get to a station, charge for 45 minutes, and drive 30 minutes to get back to their day? That’s a lot of time,” she said.


California’s sheepherders at the center of an overtime battle
(Civil Eats) Caroline Tracey, June 8

Recently, California sheep producers have found a new market: ecosystem services. Supported by landowners and grants from agencies like the California Department of Forestry and Fire, targeted grazing helps achieve environmental goals such as invasive weed control, wildfire mitigation, and soil health.

“It isn’t the classic model of livestock production, where you have the same herd and feed resources year over year and change is bad,” says Lee Hazeltine, whose business, Integrazing, brings sheep and goats to graze subdivisions and open space preserves. According to Dan Macon of University of California Cooperative Extension, the number of sheep in the state has remained about the same in recent years, but there has been an uptick in operations.

Will water restrictions bring more destructive SoCal brush fires? Some demand more water

(LA Times) Brittny Mejia, Alex Wigglesworth, June 3

…While defensible space recommendations typically call for a lean, clean and green landscape — which generally requires some amount of irrigation, depending on the type of vegetation — it's just as important for homeowners to make wise choices of what to plant and where, said Susie Kocher, forestry and natural resources advisor with UC Cooperative Extension in the Central Sierra Nevada.

"I don't care if you do irrigate, I always recommend you don’t put vegetation within five feet of your house or under windows, where if a shrub catches on fire, the heat can break a window,” she said.


Climate change is coming for your pizza sauce
(National Geographic) Alejandra Borunda, June 2

…“California is pretty unique in terms of its climate,” explains Tapan Pathak, an agriculture and climate expert at University of California, Davis. Long, sun-drenched summers with little or no rain is a “pretty perfect environment for tomatoes to grow,” he says. (Tomatoes don’t like getting their leaves wet).

…But that, says Cassandra Swett, a tomato-focused researcher at UC Davis, is often how climate change makes itself felt—not just through catastrophic fires or hurricanes, but in slower ways. The effects of a single heat wave, or an ongoing drought, ripple outward from farm to processor, processor to commercial sellers, commercial sellers to your local pizza makers—and then to the consumer.

“But the overall implication is, tomato health is being affected not just by direct impact of climate change like heat, but also by indirect effects like drought and disease,” she says.

…It’s getting harder and harder to find solutions. UC Davis’s Swett and Tom Turini are working constantly to help growers stay ahead of climate- and disease-related problems.

One promising idea was “deficit irrigation.” Turini tested how much water growers could save by shorting the plants a bit on their ideal water amounts during their last few months of growth, when they’re strong and well-established. His initial tests, run about a decade ago, looked promising: It seemed like growers could give them as little as half of what they wanted and keep the overall yield almost the same.


Drip irrigation shows promise in desert sweet corn study
(Imperial Valley Press) Joyce Lobeck, June 2

Drip irrigation can be considered as an effective and promising on-farm water conservation tool in desert sweet corn, according to a recent study conducted in several fields in Imperial County.

The findings of the study demonstrated that drip irrigation clearly has the potential to enhance the efficiency of water, Ali Montazar, irrigation and water management advisor for the University of California Cooperative Extension in Imperial, Riverside and San Diego Counties, concluded. The study also demonstrated more efficient use of fertilizer, reduced labor costs and increased yields.


Legal and illegal cannabis: A cause for growing environmental concern
(Mongabay) Sean Mowbray, June 2

…In the Western United States, for example, cannabis production has come in for much criticism as the latest threat to this precious commodity, perhaps unfairly. In California, agriculture accounts for as much as 80% of freshwater use, but “the demand represented by [legal] cannabis is a fraction of 1%,” says Ted Grantham, co-director of the Cannabis Research Center at the University of California, Berkeley. “The reason for that is that the actual footprint, the area that cannabis occupies, is [currently] very small.”

Santa Cruz County weekend fires underscore dry season dangers
(Santa Cruz Sentinel) Jessica A. York, May 31

…The holiday weekend fires came just ahead of the Sempervirens Fund’s public webinar series Tuesday afternoon, with its latest episode exploring the at-times controversial idea of prescribed fire. The land trust agency touted prescribed fire as “one of the best tools to promote ecological and community resilience in California,” noting the presence of ongoing legislative barriers to the practice’s widespread use statewide. Featured guest speaker Lenya Quinn-Davidson, director of the Northern California Prescribed Fire Council, took a wider perspective on the benefits of controlled burns and said the practice will require a grassroots push by property owners.

“When we work on prescribed fire issues, we’re not just working to prevent future wildfire, we’re really working to restore fire as a process, as a cultural tradition and to preserve a lot of the biodiversity that we have on our landscape which is a direct result of the fires,” Quinn-Davidson said.

According to a study that examined previous water restrictions in Los Angeles from 2000 to 2010, there was not a major effect on vegetation even as outdoor water use decreased, said Beatriz Nobua-Behrmann, an urban forestry advisor with the University of California Cooperative Extension.

The study examined aerial imagery to estimate vegetation “greenness” and found it remained relatively stable over the 10-year period. Though there was tree mortality in some areas, there was not a huge change overall.

“The trees are maybe going to be OK,” Nobua-Behrmann said.

"...once flames reached those homes, the fire began to spread from structure to structure....

“It actually creates a condition where the homes themselves become the fuel,” said Max Moritz, a UC Cooperative Extension specialist in wildfire at UC Santa Barbara’s Bren School. Similar patterns could be seen when the Tubbs fire swept through the Santa Rosa subdivision of Coffey Park in 2017 and when the Camp fire destroyed the town of Paradise in 2018, he said."


‘Chaos On The Horizon’: Concern Grows Over Potential Summer Power Outages In California

(CBS Sacramento) Laura Hefeli, May 6

…“Whenever there is a heat event, that’s when the grid is being taxed the most,” said Keith Taylor, a UC Davis professor of community economic development. Taylor said increased energy uses like blasting air conditioning or refrigeration could lead to issues.

“When you have 40 million people doing it at a time, that’s a lot of stress on the system,” he said. Taylor said the state’s lack of energy options like solar and wind, and the inability to borrow power from other states, make for a perfect storm.

“These other states are also going to be dealing with their own power shortage issue,” he said. “I think there’s going to be a limited amount of chaos on the horizon.”

Why climate change makes it harder to fight fire with fire
(New York Times) Raymond Zhong, May 5

In California, the winter rainy season is getting shorter but more intense, scientists say. This gives grass and brush more time to dry out and turn flammable in the fall, while still providing them ample water to grow the following spring — a double whammy for wildfire risk.

“I don’t think people realize that we’re actually at a point where, some of these fires, we cannot put them out,” said Lenya N. Quinn-Davidson, a fire adviser with the University of California Cooperative Extension and director of the Northern California Prescribed Fire Council. “We really need to be thinking in different ways about how we do things.”


Polluters are using forests as ‘carbon offsets.’ Climate change has other plans.
(NatGeo) Craig Welch, May 5

…The CarbonPlan research was published as a pre-print; it has not yet been peer-reviewed. But several experts reviewed the work for National Geographic. Daniel Sanchez, who runs the carbon removal laboratory at the University of California, Berkeley, calls it “a robust analysis that answers an important question.”

Whereas the study’s assessment of fire risk was based on a tally of actual events, the projection of disease risk is a projection, says Matteo Garbelotto, director of the University of California, Berkeley’s forest pathology lab. “But the take-home message from the research is for-sure correct,” he says. “Within 100 years, it is more likely than not that most of those areas will see the arrival of sudden oak death. And in five, or at maximum 10 years, 80 percent of the tanoak will be dead.”

Max Moritz, a wildfire specialist with the University of California Division of Agriculture & Natural Resources, says it’s not clear how representative the last few intense fire seasons will be of the future. But “even if the authors have very large uncertainties around their estimates,” Moritz says, “the lack of what is needed for 100 years of ‘permanence’ appears to be a serious challenge.”


Master Gardeners go digital, cultivate community online
(Imperial Valley Press) Madison Sankovitz, May 5

… The perfect group to aid in this mission was the UC Master Gardeners, a program that has focused on sharing research-based information about gardening and pest management with the public since 1980.

This public service and outreach program under the University of California Agriculture and Natural Resources (UC ANR) is usually administered in person by participating UC Cooperative Extension county offices, but COVID forced Master Gardeners to rethink their strategy for disseminating critical horticulture resources. Volunteers across the state showed continued to extend information by using new digital platforms and technology, efforts that have helped the program stay connected to California communities.


Dallas toddler hospitalized after being mauled by coyote in 'exceedingly rare' attack
(AP) Terry Wallace, May 4

The lack of fear of humans can be disastrous for the coyote, said Robert M. Timm, a retired wildlife biologist with the University of California's Hopland Research & Extension Center who has long studied the history of human contact with coyotes.

A report Timm co-authored for the Fall 2017 edition of the journal Human-Wildlife Interactions cited a 2009 study that tabulated 142 reported coyote attacks on humans in the United States and Canada over almost a half-century from 1960 to 2006. A 2011 study recorded 26 coyote attacks on humans in Canada between 1995-2010.

“This is a difficult problem to manage, given the diversity of public attitudes toward coyotes, especially in suburban areas,” he said in an email to The Associated Press. “It quickly becomes a political nightmare for cities, counties, and public agencies, as many people oppose any lethal control of wildlife, which at times is the only solution when some individual coyotes become habituated to living in suburbia to the extent that they attack pets and humans.”


As peak wildfire season looms, SB County Fire Safe Council looks to educate and prepare
(KCBX) Beth Thornton, May 4

Max Moritz is participating in the weekend activities. He is a state wildfire specialist and UCSB adjunct professor. He said educating the public is important since the Central Coast is prone to wildfires due to its chaparral landscape and sundowner winds.

“Often [fire] events are happening in what we call extreme weather conditions — so hot, dry, strong wind conditions,” he said.

Moritz said as we head into fire season, residents play a key role in reducing risks and making the community safer.

“Make sure you have defensible space around your home, so that firefighters have a place to work, and clean out the rain gutters so there’s not ignitable materials there,” he said.

California's new drought rules: will they be enough to halt the 'alarming challenges' ahead?
(The Guardian) Gabrielle Canon, May 3

Experts have called for stronger limits, as the climate crisis rapidly unfolds in the state and normal cycles of drought become longer and much more frequent.

“The water we have now is 40% lower than the worst-case scenario in the models ever predicted,” says Dr Kurt Schwabe, a professor of environmental economics and policy at the University of California Riverside. Schwabe added that he thinks the state is being too cautious about pushing agencies to do more. “We are in a new climate reality and we have to adjust more quickly than we had in the past.”

How to climate-proof your garden
(Sierra Magazine) Krystal Vasquez, April 25

Climate change “has had a huge impact on gardening,” said Missy Gable, director of the University of California Agriculture and Natural Resources program. “My own personal experience with gardening and climate change has seriously revolved around drought.” 

...Of course, this would all be easier if we could just control the weather. Sadly, gardeners don’t have that power … or do they? “We can control microclimates somewhat by where we place plants,” says Karrie Reid, an environmental horticulture adviser at the UC Cooperative Extension of San Joaquin County.

California Invests $3.75M to Fund Safer, More-Sustainable Pest Management
(Perishable News) April 22

  • …Assessing a biocontrol system for the management of tadpole shrimp in rice. Tadpole shrimp usefully eat some early season weeds but can cause damage to rice later in their lifecycle. To preserve their role in controlling weeds but diminish the shrimp’s later impact on the rice harvest, predator mosquito fish will be introduced mid-season to control the shrimp’s population when necessary. This research will be led by Dr. Ian Grettenberger at UC Davis.
  • Testing two emerging IPM technologies for agricultural use, the automatic release of biocontrol organisms using flying drones, and precision spray application technology, which uses much less pesticide than applying pesticide sprays using current techniques. This research will be led by Dr. Ian Grettenberger at UC Davis.
  • Developing an IPM software decision-making tool for pistachio growers that helps reduce pesticide use by guiding more precise pesticide applications when chemical use is necessary. This IPM tool leverages smart technology to help growers transition from routine preventative spraying to more limited threshold-based chemical use. This research will be led by Dr. Themis Michailides at UC Davis.

Research projects funded for urban and agriculture pest management:

  • Studying the use of a reduced-risk ”attract-and-kill” approach as an effective alternative to urban and agricultural pesticide spray programs for managing South American palm weevils, a pest that damages date palms in urban and agricultural environments. “Attract-and-kill” strategies use pheromones that attract the target pest to a small amount of pesticide that kills the insect, as opposed to spraying a large quantity of pesticide over an area to control pest populations. This research will be led by Dr. Mark Hoddle at UC Riverside.
  • Studying the impact and potential of using insect growth regulators that target Argentine ants for pest control in urban and agricultural environments. Insect growth regulators are new, safer pest management tools that pose a much lower risk of causing unintended damage to beneficial insects when compared to many traditional insecticides. This research will be led by Dr. Dong-Hwan Choe at UC Riverside.

Research projects funded for urban and nonagricultural pest management:

  • Testing non-chemical entrapment methods for trapping, monitoring and eliminating bedbugs, a significant public health pest that disproportionately affects low-income Californians. This research will be led by Dr.Catherine Loudon at UC Irvine.
  • Creating a new set of guidelines for effectively identifying and managing biting mites, a common, but poorly understood indoor pest that is often misidentified and incorrectly managed. This research will be led Dr. Andrew Sutherland at UC Agriculture and Natural Resources (UCANR).
  • Assessing a baiting system for detecting western drywood termites to reduce the number of unnecessary fumigation treatments in California homes, especially in Southern California where termites represent a significant pest problem. This system would indicate when active termite infestations have returned and if preventative treatment is needed, greatly decreasing the amount of high-risk pesticide use in homes. This research will be led by Dr. Dong-Hwan Choe at UC Riverside.

UCD Provides Sensory Tasting Guidelines for Evaluating Grape Smoke Exposure Effects
(Wine Business) Ted Rieger, April 18

The University of California, Davis (UCD) Viticulture & Enology Department presented an  extension seminar April 8th, "Evaluating Impact of Grape Smoke Exposure: Best Practices," with guidance to evaluate smoke sensory impacts on grapes and wines and how to train staff and tasting panels to recognize and rate smoke impacts. UC Cooperative Extension enology specialist Dr. Anita Oberholster moderated the meeting and provided basic science about smoke exposure based on current knowledge. "Grapes can have smoke exposure without having smoke taint," Oberholster said. She noted that smoke taint is not a single attribute, it can be described as smoky, burnt, tar, campfire, ashy, medicinal or earthy. For assessing smoke taint, the focus is on tasting for "ashy aftertaste" or a "lingering retro-nasal ashy character" on the palate.

In the valley, 'heat islands' of asphalt and fake lawn reach 170 degrees. What you can do
(Desert Sun) Janet Hartin, April 9

As a resident of the Coachella Valley for 32 years and a University of California Agriculture and Natural Resources academic specializing in horticulture, I’m asking for your help.

Please rethink the use of asphalt, black (dyed) mulch, and synthetic lawns in our desert communities. They are superheating what already are extreme urban heat islands. An abundance of living plants interspersed with light-colored organic and inorganic mulches that reduce soil evaporation between plants are better choices.  


Bay Area ranchers concerned as unseasonable heat impacts livestock, sales

Adding it all up, that means consumers will need to pay more and expect to get less at the grocery store.

“There’s a lag for short in what’s happening here in the market and then what the prices are in the market,” said Sheila Barry, a livestock and natural resources advisor for the University of California’s Cooperative Extension. “As input prices go up, that includes the cost of fuel, the cost of hay, which is now also difficult to grow when you have a lack of water. So, all those costs go up, which raises the cost of production.”

Northern California could face dire wildfire danger in 2022. How high is the risk?
(Sacramento Bee) Michael McGough, April 3

Drought is one of the big concerns, but it’s not the only factor in the state’s extraordinary wildfire risk. “The vulnerability of our forests is really catastrophic,” said Scott Stephens, a wildfire science professor and head of the Stephens Lab at UC Berkeley....

...The Biden administration earlier this year unveiled a wildfire prevention plan that includes not only planned burns and thinning, but seeks to have some of the most at-risk communities build protective boundaries. It’s a vast, 10-year plan.

Lenya Quinn-Davidson, a fire advisor for the University of California Cooperative Extension whose input is included in the plan, said the acre targets in state and federal plans are “almost arbitrary.” “The acres will come if we put all the right pieces in place,” Quinn-Davidson said in an interview.

What are the PRLR-SLICK cattle? 
(Successful Farming) Madelyn Ostendorf, March 26

…PRLR-SLICK beef cattle have been gene-edited to have short hair, a trait associated with high heat tolerance and resistance. Alison Van Eenennaam, Extension specialist in animal biotechnology and genomics at the University of California, says developers can introduce a targeted double stranded break in the DNA helix to create a desired trait.

“Editing allows you to go to a targeted location in the genome, to a particular gene that you want to modify and introduce a double stranded break in the DNA,” says Van Eenennaam. “When the cell repairs, as cells do, and they see a double stranded break, you get a repair that’s not the same as what it was before. It was cut with genome editing reagents, and that can lead to an inactivation of the gene, basically knocking out that gene.”

How dairy farmers are cashing in on California's push for cleaner fuel

(NPR) Dan Charles, Feb. 10

…Aaron Smith, an economist at the University of California, Davis, decided to examine the impact of emission credits on such dairy farms. "I had heard people saying this was kind of a big deal, and I sort of put off looking into it for a while, because I was thinking, 'How big of a deal could it really be?'" he says.

…The value of these pollution-cutting credits could amount to a 50% boost in revenue over just selling the cows' milk. Smith published the result as a blog post titled "What's more valuable: A cow's milk or its poop?" It quickly became the second-most read article on his website, only trailing a taste-test of fast-food chicken sandwiches that Smith and his daughter carried out.

Now, for the cost and inconvenience of flooding their fields, rice farmers are earning goodwill and betting that a healthy salmon population will avoid new regulations to protect wildlife and keep adequate water flowing.

In recent years, biologists discovered that as rice straw decomposes in flooded fields it creates a broth rich in fish food. They call it "zoop soup."

"The zooplankton are so big and they're so juicy, it's like filet mignon," said Andrew Rypel, a professor of fish ecology at the University of California Davis and lead investigator on the project.

To save Western U.S. forests, cut them way back, study suggests
(Bloomberg) Laura Bliss, Feb. 3

The lack of competition in the sparser forests of the past allowed for individual trees to survive and grow, the scientists believe. Those bigger, healthier trees were then able to persist through recurring fires, acute dry spells, insects and disease. Modern-day forest managers should take note, the study suggests.

“There’s a lot of disturbance that one individual has to tolerate before they make it to that size,” said co-author Ryan E. Tompkins, a UC Cooperative Extension forest and natural resources advisor. “We need to start managing for a competition-free environment if we want to maintain these large trees.”

(KVPR NPR of Central California) Kerry Klein, Jan. 28

The U.S. Department of Agriculture has announced a new round of grants to support climate-smart agricultural practices, and $1.5 million is headed for Merced.

The team, led by Tapan Pathak, a research specialist at the University of California Cooperative Extension and UC Merced, is one of six public entities to split $9 million in awards from the Agriculture and Food Research Initiative within the USDA’s National institute of Food and Agriculture (NIFA). The goal of the investment is to bolster climate research and build connections with the agricultural community.

…“This kind of grant is super critical in expanding our reach and addressing issues faced by farmers and ranchers across the state,” said Pathak. “Our hope is to develop tools that can help growers make strategic decisions to minimize some of the risks."

K&J Orchard’s Cult-Favorite Asian Pears Are Getting Their Own Restaurant in Oakland
(SF Eater) Maria C. Hunt, Jan. 21

…The restaurant name finds its origins in the Latin word pometum, which means a fruit tree grove. Pomet (pronounced POM-et) is the Romanian word for orchard; it’s a tribute to her mother Kalayada Ammatya and father James Beutel who started K & J Orchards in 1982. Beutel, who died in 2016, was a noted fruit researcher, lecturer, and Cooperative Extension agent with University of California, Davis for 35 years. He was also the pioneering pomologist who introduced fragrant Asian pears and kiwifruit to California and worked on making the pear and peach tree varieties in California more hardy, according to the UC Davis website.

Experts Weigh In On Biden Administration’s $50B Wildfire Crisis Plan
(CBS13) Madison Keavy, Jan. 20

…“It’s just reality that it is expensive to do this work,” said Robert York, Assistant Cooperative Extension Specialist and Adjunct Associate Professor of Forestry at UC Berkeley.

…“It could’ve cost $2,000 an acre to do that initial treatment, now, to do a prescribed fire because we’ve managed it in the past, it’s much more affordable,” said York.

He uses the Blodgett Forest Research Station as an example of what it takes to get land “back on track” when it comes to management. Now, he said, it costs around $200 to do the same work, with regular maintenance.

Closing Broadband Gaps Remains Critical, WIth Or Without A Pandemic
(CA FWD) John Guenther, Jan. 19

Glenda Humiston: COVID has been a real game-changer in so many ways. We had to turn on a dime. People had to work remotely, work from home, have their kids at home, telemedicine. We discovered just how critically important access to the internet is. And good access to the internet, which is broadband. It’s not just rural California, we’ve got big chunks of urban area that have very poor coverage.


What is a healthy forest in California? These scientists are experimenting west of Lake Tahoe.
(CapRadio) Manola Secaira, Jan. 19

What does a healthy forest look like? 

There are dozens of ways you could find an answer, but Rob York [UC Cooperative Extension specialist] has his own simple litmus test. It starts with his own question: 

“Can you run through it?” 

…And now researchers say that managing California’s forests means a balancing act. 

“It’s really a societal question on what mix you’re able to have,” said John Battles, a professor of forest ecology at UC Berkeley who’s conducted studies in the forest. “And then that becomes, ‘How do you balance those?’”

(California Ag Today) Mike Hsu, Jan. 17

Heat waves were a major driver of the INSV disaster of 2020. Although researchers have established a link between warmer temperatures and population increases of thrips, science still has a lot to learn about those disease vectors.

“Thrips are something we’re trying to understand as much as we can, but it’s pretty tough because they’re a little mysterious in the way they get around and where they overwinter,” said Richard Smith, a University of California Cooperative Extension vegetable crops and weed science farm advisor for the Central Coast region.

Del Norte Board of Supervisors Still Question New Fire Safe Regs' Impacts on Development, Sends Second Letter to California Board of Forestry
(Wild Rivers/Lost Coast Outpost) Jessica Cejnar Andrews, Jan. 13

…The letter hasn’t been drafted yet, Community Development Director Heidi Kunstal told supervisors. She said she’s working with representatives at Rural County Representatives of California as well as Yana Valachovic, the U.C. Cooperative Extension’s Humboldt-Del Norte County director.

According to Valachovic, who worked with county supervisors to draft a comment letter on the same regulations in April 2021, the state’s fire safe regulations focus on access to a parcel of land. This includes mandating road widths, length of driveways, weights that bridges can carry, water availability for fire suppression and if there’s an alternate way to get through an electronic gate should the power fail.

Alfalfa suits a water-challenged future
(Hay and Forage Grower) Mike Rankin, Jan. 11

The current drought in the West has likely had no greater impact on other agricultural entities than on alfalfa, according to Dan Putnam, the longtime extension forage agronomist with the University of California in Davis.

“Drought is nothing new,” Putnam asserted while speaking at the Western Alfalfa & Forage Symposium in Reno, Nev., last November. “It’s something we’ve seen in the West for many years. But drought isn’t necessarily our biggest challenge; it’s more the variation in water supplies as we can go from drought to periods of flooding in a short period of time.” Regulatory curtailments of water supplies are also a major concern.


2021’s biggest climate and weather disasters cost the U.S. $145 billion – here’s what climate science says about them in 5 essential reads
(The Conversation) Stacy Morford, Jan. 10

… As rising global temperatures dry out vegetation, forest managers are dealing with increasing wildfire risks and costs. Fighting huge wildfires, like the Dixie and Caldor fires in California that destroyed much of Greenville and Grizzly Flats in 2021, depletes funds needed for fire prevention efforts, such as forest thinning and prescribed burns, University of California forest and fire experts Susan Kocher and Ryan Tompkins wrote.

“To manage fires in an era of climate change, where drier, hotter weather creates ideal conditions for burning, experts estimate that the area treated for fuels reduction needs to increase by at least an order of magnitude,” they said.

Is a State Program to Foster Sustainable Farming Leaving Out Small-Scale Growers and Farmers of Color?
(Inside Climate News) Anne Marshall-Chalmers, Jan. 4

… “It’s the law,” said Ruth Dahlquist-Willard, a small farms advisor with the University of California Cooperative Extension in Fresno.

… Dahlquist-Willard recently analyzed where small, diversified farms owned by Southeast Asian immigrants were located in Fresno County. She found that nearly 63 percent were outside the boundaries of disadvantaged communities. In areas near the central California coast, up to 94 percent of small scale Asian and Latino operated farms were outside of those designated priority areas.

(NBC News) Tim Stelloh, Jan. 4

Matteo Garbelotto, a forest pathologist at the University of California, Berkeley, told [NBC Bay Area] that such rot is becoming increasingly common in the state’s overgrown forests as a drought worsened by climate change pushes dense trees to compete with one another for water.

The added stress makes trees less resistant to rot, Garbelotto said.


Capturing the Flood in California’s Ancient Underground Waterways
(Bay Nature) Erica Gies, Jan. 4

…These events repeated themselves over the last million or so years, as glaciers crept down from the north, then retreated. Four of these events have left imprints of their icy ebb and flow below the valley floor. Called paleo valleys, these buried historic riverbeds are still the paths water wants to travel underground, like slow-motion rivers. Their extreme permeability means they can absorb about 60 times more water than the surrounding clay. Aquifers, which are better known, also hold water in coarse soils. But the paleo valleys born of the most recent glaciations are truly special, according to UC Davis professor emeritus of hydrogeology Graham Fogg—the most significant feature underlying the Central Valley. They have super powers for moving water underground because they are exceptionally large, have unusually coarse gravel, and are relatively shallow—perhaps just a meter or two below the surface. Fogg says that every significant stream coming out of the Sierra today should have paleo valleys buried in the plateau. But only three have been discovered so far in California.


Arizona wants to use more inmates as wildland firefighters — but at what cost to the prisoners?
(Arizona Republic/KJZZ) Ron Dungan, Jan. 2

California has used inmate fire crews for decades. Fire adviser Lenya Quinn-Davidson says the program does not always translate to jobs for inmates.

“But one of the roadblocks historically had been that you can’t get a job in fire if you have this criminal background,” Quinn-Davidson said.

Inmates make up a large percentage of California’s fire crews, “and they really have become a critical piece of the puzzle,” she said.

…Grace Woodmansee, UCCE livestock and natural resources adviser in Siskiyou County, told WLJ the 2011 survey was a starting point to see what ranchers experienced and how they adapted during the 2012-16 drought. 

“We were interested in seeing if the (2012-16 drought) changed the way ranchers thought about drought management planning and if there were any opportunities, from a support agency perspective, to adapt the way we do our extension work or influence the way policy is developed and meet people after managing through such a severe event,” said Woodmansee. 


Conservationists create a vast home on the eco-range for wildfire north of L.A.
(Los Angeles Times) Louis Sahagún, Dec. 24

Moderate levels of cattle grazing around ephemeral ponds that form seasonally, under certain conditions, lead to a greater number and greater variety of native plants, according to a recent study led by researchers at UC Davis and UC Agricultural and Natural Resources.

“Livestock grazing can be used as a conservation tool, provided you have a plan,” said Ken Tate, co-author of the study. “It’s on the shoulders of the land managers to set goals and objectives and then meet them.”

'Fuel for the next fire': Why California can't unload the trees that worsen its wildfires
(Sacramento Bee) Dale Kasler, Dec. 19

There’s no obvious quick fix for “this deficit of capacity,” as Robards called it. The facilities have been in decline for decades — lumber mills have been disappearing since the early 1990s, largely because of environmental restrictions, and the biomass industry has been battered by competition from cheaper energy sources.

“We had this robust infrastructure,” said Mike De Lasaux, a retired forester with UC Cooperative Extension. “Now we see these humongous piles of treetops and small trees that have no place to go.”

California Economic Summit Forges A Path To Water Resiliency
(California Forward) Judy Corbett, Dec. 14

The health of California’s economy depends on an adequate supply of clean water. Fortunately, the ideas of innovative water leaders across the state are making their way into state action plans.

In recognition of the threat to water supplies from increasing droughts and floods, UC Agriculture and Natural Resources Vice President Glenda Humiston – a California Economic Summit work group leader and a member of the California Stewardship Network – invited 25 of the State’s most innovative local elected officials and land use planners and 25 progressive leaders from local water districts to a symposium on land use and groundwater recharge. The year was 2016. Most of the participants were already locally implementing cutting edge policies connecting land use and the recharge of groundwater aquifers. Also participating at Symposium were university researchers and top-level members of the Brown Administration.


New study sheds light on how deer cope with wildfires
(Field & Stream) Ken Perrotte, Dec. 13

A study reported in the journal Ecology and Evolution in late October reveals insights into how blacktail deer responded following the catastrophic 2018 Mendocino Complex Fire in California. Somewhat surprisingly, the deer demonstrated a powerful loyalty to their small home ranges, returning soon after the fire and living on the scorched ground, even though high-quality, unburned habitat was available about a mile away.

The research, led by Samantha E.S. Kreling and Kaitlyn M. Gaynor, involved 18 radio-collared deer at the University of California’s 5,358-acre Hopland Research and Extension Center. The center is the principal field research facility for agriculture and natural resources in the state’s North Coast region.

California goes to war with food waste: Composting is its next climate crusade
(Los Angeles Times) James Rainey, Dec. 9

Scientists have found that this kind of reconditioning of biological matter produces far less Earth-warming methane and carbon dioxide than landfilling. The atmospheric benefit is compounded when farmers put the compost onto their fields, often to feed “cover crops” such as mustard that help sink carbon back into the Earth.

“It’s like a no-brainer,” said Kate M. Scow, a soil scientist at UC Davis, who has measured how compost helps remove greenhouse gases from the atmosphere. “You can’t build carbon in the soil unless you feed carbon in. ... It’s a way of closing the loop.”

Drought curbs spread of sudden oak death in California
(Press Democrat) Guy Kovner, Nov. 29

Below average rainfall was the primary reason for the overall low infection rate this year, [UC Cooperative Extension specialist Matteo] Garbelotto said.

The pathogen that causes sudden oak death — a fungus-like water mold — rides on droplets blown during warm spring rain from the leaves of bay laurel trees, a host species, to susceptible oak and tanoak trees.

"The disease comes in waves every time it rains a lot," he said.

Yana Valachovic, forest advisor for the University of California Cooperative Extension in Humboldt and Del Norte counties, agreed that “trends are going in the right direction” but warned that “current conditions aren’t necessarily a prediction of future conditions.”

“We really lucked out by getting that early season rain,” she said. “… We often get a prolonged dry period in December, January, and February, so things could reverse pretty quickly too. We’re hopeful that they go in the right direction, but just keep in mind that we can have fire activity or fire behavior during that winter dry period or if the season shortens up pretty quickly like it did last year when we didn’t get precipitation after March.”

...Another 5,000 acres were treated with broadcast burning, which in combination with thinning has shown to be most effective.

“That’s just depressing,” said Lenya Quinn-Davidson, fire advisor for the University of California Cooperative Extension. “That’s so little, given how much land the Forest Service manages in California. It is just a drop in the bucket.

“I think it speaks to the need for such drastic change around prescribed fire.”


Family farms struggling as California drought worsens: 'We haven't faced anything like this'
(Central Valley News Collaborative) Nadia Lopez, Nov. 5

...Water scarcity, combined with these other challenges, could lead to thousands of families losing their businesses and no longer supplying specialty fruits and vegetables to markets and businesses across the state, resulting in the “increase towards more consolidation into larger farms that are going to be less diverse,” according to Ruth Dahlquist-Willard, a small farms advisor for the University of California Cooperative Extension.

“There’s a lot at stake,” said Dahlquist-Willard, who helps connect diverse and socially-disadvantaged farmers to resources. “The viability of smaller farms might be affected and our landscape will continue to change to maybe a few more high value crops versus a bigger diversity of a lot of different kinds of crops.”

So, if we know what works, why isn’t it happening? “That’s the million-dollar question,” said Lenya Quinn-Davidson, a fire advisor with the University of California Cooperative Extension in Humboldt County and the director of the Northern California Prescribed Fire Council. “The holdup is so multifaceted.” Hurdles include getting vast numbers of private landowners to work together and understand what they need to do, dealing with federal and state regulatory barriers, permitting red tape, an insufficient federal workforce, a lack of funding, the risks stemming from liability and insurance policies, and a deeply ingrained fire suppression mentality.


California drought persists, even with recent rain. Conserve water now with these tips

…Drought pushes farmers to shift their scarce water resources to crops with higher payoffs, such as nuts and vegetables, said Daniel Sumner, an agricultural economics professor at the UC Agricultural Issues Center — a trend particularly noticeable this year with its uniquely severe drought.


Historic rain and snow begin to refresh California lakes and mountains
(Washington Post) Kasha Patel and Zach Levitt, Oct. 27

"It is great that we received this much rain early in the season, which helped with wildfires and air quality,” wrote Helen Dahlke, associate professor in Integrated Hydrologic Sciences at the University of California at Davis, in an email. “The more these precipitation events are spread out over the rainy season the more chance the rain has to infiltrate and replenish soil moisture storage.”


Storm took a big toll on Bay Area trees. Did the drought make them more vulnerable?
(San Francisco Chronicle) Kellie Hwang, Oct. 26

Of course, big storms always claim trees as casualties.

“A powerful storm will inevitably result in some damage to trees, whether from falling branches or even uprooted trees,” Igor Lacan, urban forestry adviser for the UC Cooperative Extension, wrote in an email.

However, California’s historic drought is “certainly not helping,” he said. “A drought will have weakened some trees and even killed some,” priming them to topple in a storm.


Current approaches to wildfires risks lives and wastes money, say experts
(The Guardian) Sarah Johnson, Oct. 24

As Cop26 approaches and is expected to shine a light on the importance of protecting ecosystems and building defences to avoid loss of homes and lives, experts say a lack of foresight and funding worldwide means harmful wildfires will continue to rage, putting communities and firefighters in danger.

Lenya Quinn-Davidson, a fire adviser at the University of California, said: “We’re seeing our historical approach to fighting fires is no longer working. We saw this summer in California that going out, attacking fires and putting them out was totally ineffective.”


Thirty years after the Tunnel Fire: In many ways, Oakland Hills are more vulnerable today
(SFbay.ca) Nik Wojcik, Ian Sumner, Oct. 21

…Matteo Garbelotto, University of California, Berkeley professor and one of the state’s leading tree pathologists, was contacted this year by the U.S Forest Service and the San Francisco Public Utility Commission and asked to conduct an investigation. He was basically told: 

“You got to stop everything you’re doing and you’ve got to work on this.” 

The agencies were urgently concerned with a surge of tree death in the Bay Area. While eucalyptus trees were being impacted, Garbelotto found a “much greater mortality” in acacias. 

What he observed across the state were two already identified native, or naturalized, fungi that grew rampant as a result of the abnormally wet 2017 winter. The “opportunistic organisms” have infected non-native, invasive acacias, which are already stressed by drought and high propagation rates..He believes the infection may be spreading to eucalyptus as well. 

But Garbelotto discovered a third fungus unique to the Leona Heights neighborhood in the Oakland Hills, which compounds morality in that area. 


New Farm Advisor shares plans with BOS
(Lake County Record-Bee) Bernadette Hefflefinger, Oct. 21

The new County Director for Mendocino and Lake Counties’ UC Cooperative Extension (UCCE) program  made a meet-and-greet Zoom appearance to share information with the Lake County Board of Supervisors at Tuesday’s meeting. Livestock and Natural Resources Advisor John Harper told the BOS he’s no stranger to the ‘county director’ role tasked with administering and supervising the fiscal, policy and personnel responsibilities of the UCCE’s program in the two counties. He held a similar position some 15 years ago and has stepped into the role again following the subsequent retirements of Rachel Elkins and Glenn McGourty from their respective roles as Pomology Advisor and Viticulture and Enology Advisor, and the departure of Car Mun Kok as the 4-H Youth Advisor.


A biblical plague or a winged love story? The truth about California's annual termite swarms

"Absolutely," said Andrew Sutherland, the urban integrated pest management adviser for the Bay Area at the University of California Agriculture and Resources. "Most likely what's being observed are swarms of western subterranean termites."


What does California’s drought mean for the rest of the country
(Marketplace) Samantha Fields, Oct. 20

… So far, Munch said, American consumers haven’t really been feeling the effects of the drought in California. The longer the drought goes on, the more likely that is to change, according to Tapan Pathak, an agricultural climate scientist at the University of California, Merced.

“We could potentially see reduction in the availability of the fruits and vegetables that’s consumed by people every day,” Pathak said — things like lettuce, lemons, avocados and all sorts of nuts.

“At the same time, we could potentially see higher food prices,” Pathak added.


UC Berkeley students clean eucalyptus debris to prepare for fire season
(Daily Cal) Lance Roberts, Oct. 20

…Eucalyptus trees are quite a problem for California — according to campus professor of environmental science, policy and management Matteo Garbelotto, eucalyptus oils are easily ignited. When they are set ablaze, Garbelotto says that the gases formed from the oil cause something similar to an “explosive combustion.”

What’s worse, a pathogen is making eucalyptus trees even more flammable. The pathogen, called Pseudosydowia eucalypti, is a major reason why so many eucalyptus trees are drying out and posing a threat, Garbelotto said.

“In some of these strands (of eucalyptus trees), a hundred percent of the trees are infected by this fungus,” Garbelotto said. “Basically it’s like firewood ready to be burned.”

Citrus Cost Study Outlines Production in the San Joaquin Valley
(AgNet West) Brian German, Oct. 18

…“If you’re a new grower you kind of want to know what it’s going to cost to grow the oranges and it really does do a pretty good job of that. We really look into the cost in some detail. It’s not only to produce oranges, but also to plant them. It covers a whole range,” said co-author Craig Kallsen, UC Cooperative Extension farm advisor in Kern County. “For new growers, it gives them an idea of what they need to do. It’s almost like a production manual because it tells them when to do it as well because the costs are associated with doing various things at various times during the year.”


Pork is already super expensive. This new animal-welfare law could push prices higher
(CNN) Alicia Wallace, Oct. 17

…A trio of economists at the University of California Davis College of Agricultural and Environmental Sciences estimate the annual costs to consumers in California will be about $320 million annually, or about $8 more per person. They also project consumers in the state will buy about 6.3% less pork.

…"There may be a brief period of disruption [when the regulations start Jan. 1], but nothing like the apocalyptic predictions of significant long-term shortages or drastically higher prices," Richard J. Sexton, report co-author and distinguished professor of agricultural and resource economics at UC Davis, told CNN Business.

Wildfire Torched the Sierra All Summer, Evading Containment. Here’s How Tahoe Protected Itself
(KQED) Ezra David Romero, Danielle Venton, Emily Zentner, and Raquel Maria Dillon, Oct. 5

Susie Kocher watched with increasing dread as the Caldor Fire roared across the western slope of the Sierra Nevada, churning toward her home near the base of Echo Summit.

From high along the granite ridge nearby, the view of Lake Tahoe is normally pristine — a cerulean ocean in the sky, dotted with boats and casinos lining the pine forest along the South Shore. But for two weeks at the end of August, smoke as brown as car exhaust clouded the basin’s air.

As Kocher well knows, having worked tirelessly for more than a decade to prepare this community for a wildfire as a UC Cooperative Extension forestry adviser, under almost every tree near South Lake Tahoe is a house.


Water is scarce in California. But farmers have found ways to store it underground
(NPR) Dan Charles, Oct. 5

…Flooding more land probably will flush those agricultural pollutants into aquifers, says Helen Dahlke, a hydrologist at the University of California, Davis. "We often see a spike in nitrate, for example, at the groundwater table below a recharge site," she says.

In the long run, though, she thinks it will be good for water quality. "Most of the water that we use for recharge is very clean, because it comes from rainfall or snowmelt from the Sierra Nevada Mountains," she says. "Eventually there will be a pulse of clean water also coming into the aquifer, which can dilute many of the pollutants that have moved into the groundwater over the last couple of decades."

Facing Drought, Wildfires, Scorching Heat, Bay Area Wineries Are Changing How They Grow Grapes
(KQED) Ezra David Romero, Sept. 30

…A study released this summer by Kaan Kurtural, a UC Davis viticulture specialist, found that California's wine industry is "not at a tipping point" because of climate change or its effects — although heat waves and fires can have an immediate impact on winemaking.

"I tell the growers your grapevines are not going to die," he said. "They might not be economical to grow for one or two years, but they always come back. There are very resilient plants. So we're able to adapt."

He also found that the climate has warmed steadily in California since the 1980s. But he says this has not been bad for the wine industry in the Golden State  — a warmer climate helped establish the state as a premier wine growing region globally.

"As it became warmer we started harvesting sweeter grapes, and with sweeter grapes, the wine ratings have steadily increased," he said.


How to protect your home from wildfires
(Washington Post) Aaron Steckelberg and Tik Root, Sept. 30

…Embers can also find their way into your home through vents, such as those in the attic or in the roof’s overhang. Yana Valachovic, a forest adviser affiliated with the University of California, notes there have been technological developments in this area. For instance, there are vents designed to swell when exposed to heat as a way of sealing off a house.

…Outside your home, the goal is to remove as much potential fuel for the wildfire as possible. The first five feet are particularly crucial, experts say. “By doing that first five feet, you basically interrupt the pathway of the flames to the house,” said Valachovic.

Scientists Are Racing To Save Sequoias
(NPR Short Wave) Maddie Sofia, Sept 28

… Without fires, the Forest got a lot denser. The trees are closer together. The undergrowth has built up, and that's what's helping fuel these really extreme fires, the kind that sequoias, it turns out, just can't survive. That's what was striking to Scott Stephens. He's a UC Berkeley fire scientist who was out with the field crew that day. They were there to catalog the mortality but also to study the forest density around the sequoias.

SCOTT STEPHENS: You know, they've been here 1,500 years. You know, and each tree maybe survived 60, 70, 80 fires. You know, that's incredible. And then one fire comes in 2020. And all of a sudden, they're gone. That is a travesty.

Raging Debate Over Burned Trees Could Leave Residents Vulnerable to Disastrous Fires
(NBC Bay Area) Bigad Shaban and Robert Campos, Sept 20

…“That is entirely bogus,” said Dr. Brandon Collins, a forest research scientist.  "There's nothing in the scientific literature to support that." Collins works with the U.S. Forest Service, but only spoke to the Investigative Unit in his capacity as a Fire Science professor at U.C. Berkeley. He calls Hanson’s study “flawed” and maintains leaving burned logs in the forest will not slow down future fires.

“In fact, it's actually quite the opposite. The Creek Fire, actually, was a great example of that,” said Collins. “We believe that most of what fueled that growth was the dead trees that were killed during the drought that preceded that fire by four or five years.”

Torture orchard: Can science transform California crops to cope with drought?
(East Bay Times) Julie Cart, Sept 13

…“This is different from the last drought. What’s changed is how fast things are happening,” said Sam Sandoval Solis, an associate professor at UC Davis and a cooperative extension specialist who advises farmers on efficient water management.

…One test for tree crops, developed at UC Davis, works something like a blood-pressure cuff. Now an industry standard with different versions available to growers, the so-called pressure bomb device essentially monitors the moisture levels in a tree’s miniature plumbing system, said Ken Shackel, a professor of plant sciences at the university.

…Pat J. Brown, a UC Davis associate professor who is a nut crop breeder, selects varieties for low-water requirements and indifference to saline soils. At the Torture Orchard, Brown and his colleagues fed pistachio trees increasing amounts of salty water. Scientists were delighted that their work did not kill a single tree, suggesting that growers someday may be able to use briny water, not just scarce fresh water, to irrigate  orchards.

…The gnarled trees produce a small, blonde nut, the favorite of Tom Gradziel, a Davis professor of plant science and an almond breeder. Gradziel walks through the orchards the way farmers do, reaching out to pluck fruits and nuts, checking them and absently snacking as he goes.



Sacramento’s wine scene touches Lodi, Clarksburg & Amador CA

… But as with grapes grown around Clarksburg, Plymouth and the Capay Valley, some stick around and end up producing exceptional small-batch wines right in Sacramento’s backyard. Area micro-producers keep their region’s grapes local and turn out world-class wine, UC Davis viticulture and enology department chair David Block said.

“Some of these places are making wine that rivals Napa and Sonoma and places in Northern California that are maybe more known for their wine,” Block said. “Are they the same as wines in Napa? They aren’t the same because they’re made in a different place. Are they as good? I think some of them are probably as good, if not better.”

CA’s Dixie Fire puts Ag Pass program to test
(Western Livestock Journal) Charles Wallace, Sept. 3

…According to the California Department of Forestry and Fire Protection (CAL FIRE), as of Aug. 4, the Dixie Fire was 274,139 acres and 35 percent contained. Tracy Kay Schohr, University of California (UC) Cooperative Extension (UCCE) livestock and natural resources adviser for Butte, Plymouth and Sierra counties, told WLJ some livestock producers are in the mandatory evacuation area, particularly in the burn area of Greenville/Indian Valley of Plumas County.

“The concept of it is completely working,” Schohr said. “Before the fire became a major incident and was being managed by just the Butte County CAL FIRE, I got a phone call from a CAL FIRE captain who asked me, ‘Hey, I know there are cattle in this area, can you figure out whose cattle they were in Plumas County? The fire is headed that way. They probably have two days to get their cattle out.’ And so the relationships that we had built, working with CAL FIRE to develop the Ag Pass program really facilitated that communication back to me.”

… Dan Macon, UCCE Livestock and natural resources adviser, told WLJ the livestock access program for Placer/Nevada/Yuba counties was developed based on examples from other counties in the state.


Wildfires in the West are inevitable, but this strategy can help control them

…“I do think the Dixie and the way that it’s burned and its magnitude did impact the early response to the Caldor,” said Scott Stephens, a professor of wildland fire science at the University of California, Berkeley. “It really drew resources down so much that the Caldor got very few for the first couple days.”

…“They’re trying to predict winds at a mountain pass. That is the most complex topography we have,” [John] Battles [a UC Berkeley professor of forest ecology] said. “That’s why you have this feeling like they didn’t know what they’re doing.”

To Stop Extreme Wildfires, California Is Learning From ... Florida?
(WKMS) Lauren Sommer, Aug. 31

Now, several Western states are moving to adopt the fire policies pioneered by Florida and other Southern states as a hedge against the future. They include training problems for burn leaders and providing liability protection for them. The bigger challenge is changing the culture around fire, so that residents know that tolerating a little smoke from good fires can help stop the destructive blazes that cloud the air for weeks.

"We have this generational gap in fire knowledge in the Western U.S. that we're trying to rebuild now," says Lenya Quinn-Davison, a fire advisor for the University of California Cooperative Extension. "But Florida and the Southeast still have it."

Those soil test results are key inputs for one of his newest tools: CropManage, which is operated by the University of California Cooperative Extension and uses data from NASA and other sources to create customized irrigation and fertilizer recommendations. In addition to satellite measurements of crop development, it gauges local weather, soil characteristics, and irrigation system efficiency.


No Prop 12 delay as state's pork prices set to rise
(Farm Press) Tim Hearden, Aug. 30

…The hearing came as University of California, Davis economists estimated on Aug. 27 that California pork consumers will lose $320 million per year (roughly $8 per person) from the market impacts of Prop. 12. California consumers will pay about 8% more for pork regulated under Prop. 12 and will consume around 6% less of that pork per year, according to the study.

“The roughly 9% of North American sows affected will each get about 20% more housing space," noted coauthor Richard Sexton, a UC Davis professor of agricultural and resource economics. "But, the additional space will be for those sows that already have more space, not those confined in small individual stalls.”

Landscaping with wildfires in mind can help homes
(Western Farm Press) Pamela Kan-Rice, Aug. 26

What can Californians do to improve the chances that their homes will survive a wildfire? Simple actions taken around the home can substantially improve the odds that a home will survive wildfire, according to UC Cooperative Extension advisors. 

During wildfire, structures are threatened not only by the flaming front of the fire, but also by flaming embers that are lofted ahead of the fire front and land on fuels such as vegetation or mulch next to the house, igniting new fires. Traditional defensible space tactics are designed to mitigate threats from the flaming front of the fire but do little to address vulnerabilities to embers on or beside a structure.

The auction grossed about $519,000—and led to more support for a Dixie Fire relief fund. Neer said Five Marys Farms out of Fort Jones in Siskiyou County came to the auction with the intention of supporting Indian Valley students who lost homes and animals to the fire. Five Marys resold its auction purchases and donated the funds to Dixie Fire relief efforts.

Other donations were made to the Clayton Floyd Neer 4-H Steer, Swine, Sheep and Goat Loan fund, Neer said.

I am interested in understanding the emergence of novel plant diseases and their effect on plant survival and on biodiversity. Humans depend on plants for survival and the globe needs plants to maintain functional ecological processes. Emergent diseases can wipe out entire plant communities with cascading effects on human well being and our planet resiliency. Until recently our main target was represented by the study of exotic plant diseases mostly introduced by trade, but we also focusing now on diseases that are becoming increasingly emergent because of climate change. These diseases represent an even more formidable foe.

By nearly every metric, the wildfires in the Western United States are worsening. They are growing larger, spreading faster and reaching higher, scaling mountain elevations that previously were too wet and cool to have supported fires this fierce.

They are also getting more intense, killing a greater number of trees and eliminating entire patches of forest.

“Ten years ago, we weren’t really seeing fires move like that,” said Lenya Quinn-Davidson, a fire adviser for the University of California Cooperative Extension, referring to 2021’s Bootleg Fire, which began July 6 and at one point consumed more than fifty thousand acres in a single day.

Exploding California Wildfires Rekindle Debate Over Whether to Snuff Out Blazes in Wilderness Areas or Let Them Burn – Inside Climate News
(US News Mail) Aug. 11

Before Euro-American settlement, an estimated 4.5 million acres or more would burn in California every year. Last year’s historic fire season charred a little more than 4 million California acres, and nearly 10 million acres throughout the West, the second most acreage burned since 1960. 

“This was a fire adapted ecosystem. The higher up you went in the mountains, the more there was an influence from lightning,” said Susie Kocher, forestry and natural resources advisor for the University of California Cooperative Extension. “But lower down and on the coast, it was mostly Native burning.”

‘Where do I go?’: Thousands flee as Dixie Fire morphs into third-largest blaze in California’s history
(Washington Post) Aaron Williams, Marisa Lati, and Maria Luisa Paul, Aug. 8

The Dixie Fire covers more than 432,000 acres in Butte and Plumas counties, rapidly expanding from about 362,000 acres Thursday evening and fueled by hot, arid and windy conditions. The wildfire was 35 percent contained by Friday, pushing toward firefighters’ control lines. Fire officials expressed hope Friday that higher humidity would help them counter the blaze.

“It’s kind of the perfect storm,” Yana Valachovic, forest adviser and county director at the University of California Cooperative Extension, said of the Dixie Fire. “We saw all this. The potential was high this year for these kinds of conditions, and once you get an ignition, especially in areas that are a little bit difficult to access and with new communities all around there, it stresses the system.”

(AgFax) Evie Smith, Franz Niederholzer, Katherine Jarvis-Shean, and Luke Milliron, University of California Cooperative Extension Specialists, Aug. 5, 2021

Please note that the following are general recommendations intended to help you keep track of regular practices in a busy time; the optimal timing for management practices may vary based on specific location and conditions.

NOW Management in pollinizers: After Nonpareil harvest you may want to spray pollinizer varieties for NOW management. The decision of whether to spray or not should be based on the amount of NOW damage observed in your Nonpareil almonds, progression of the third NOW generation, and when the fourth generation egg laying will start. If you do choose to spray, plan your application timing based on when you expect to harvest your pollinizers, remembering that pre-harvest intervals are based on the date that you shake, not the date that you pick up the almonds from the orchard floor.

(Western Farm Press) Lee Allen, Aug 4

One of the major flies in the optimistic ointment comes from the California Farm Bureau Food and Farm News showing that wild temperature swings last fall are believed to have caused widespread freeze damage in some walnut groves. Temperatures dropped from 80 degrees to below freezing in several areas, with the most pronounced swing happening in Butte, Glenn and Tehama counties, according to the Farm Bureau.

University of California Cooperative Extension farm advisors, including Luke Milliron, reported the ‘winter kill’ was severe enough to affect both young and old walnut trees, some of which “were wiped out with minimal spring leaf-out,” he said.

As drought worsens, regulators impose unprecedented water restrictions on California farms
(LA Times) Julia Wick, Aug. 3

…“It’s kind of the topic of conversation everywhere, whether you’re in the feed store or the grocery store or when I’m at work as a [UC Cooperative Extension] livestock advisor,” said Josh Davy, a small-scale cattle producer in Shasta County.

The perceived comfort of his local irrigation district’s pre-1914 water rights was a key component of Davy’s decision to purchase his ranch two years ago. He’s currently planning to sell his calves early at a loss and fears having to subdivide his property to pay his mortgage. Davy said that without water to irrigate his ranch, the pastures his cows graze on will quickly dry up and the current price of alfalfa negates buying hay as a sustainable option.

“Most of us that went this route, investing in property with these water rights within these districts all did it for very similar reasons in that there was security in that,” Davy said. “And now seeing that security gone, we’re really scared.”

Marin Master Gardeners’ drought-tolerant demonstration gardens offer inspiration
(Giving Marin Community Partnership) Jane Scurich, July 30 

As the reality of our water crisis settles in, and we begin to think seriously about saving every precious drop, it’s time to plan for some drought-tolerant replacements for our lawns as well as thirsty annuals and perennials. Garden books and visits to local nurseries provide lots of ideas, but there is nothing like observing a drought-tolerant specimen thriving in an actual garden. There may be no place better to begin your search than the UC Marin Master Gardeners’ demonstration gardens.


Experts, UC scientists discuss wildfires in the state’s riskiest regions
(San Francisco Examiner) July 30

Broad data patterns on climate change, frequency of fires or dry vegetation do not tell the whole story on California’s wildfire problems, according to Max Moritz, statewide wildfire specialist at the UC Cooperative Extension. People and the changes they’ve made to the landscape matter, too.

“That’s because we have done a lot of things to our landscape at finer scales,” Moritz said. “Look at the power line infrastructure. We’ve got road networks, we’ve got housing developments at different densities across the landscape.”


More ‘good fires’ could help California control future catastrophes
(US News Mail) July 28

In order to get the state back on track with its historical fire patterns, researchers suggest that about one million acres should be burned every year. The reality has been more than an order of magnitude away, despite persuasive evidence that prescribed burns are effective.

“We are just so out of touch with fire now,” says Lenya Quinn-Davidson, a fire expert at the University of California’s Humboldt extension. “So much of our forests have this huge backlog, and we’re going to need to use prescribed fire to protect resources we care about—communities, places we love—and set larger landscapes up to thrive again.”

…Prescribed fires have already played a role in protecting WUI areas in places like Florida, which sometimes burns more than 2 million acres annually, according to Lenya Quinn-Davidson from UC Agriculture & Natural Resources.

“If any of you have traveled in Florida, or maybe some of you have even burned in Florida, you’re often right near homes, you’re seeing smoke right behind the grocery store, in the back 40 on private property,” Quinn-Davidson said. “Prescribed fire is part of the culture there, and it’s really integrated in and amongst human habitation, so it’s a great example and somewhere we should really be looking to understand the role of prescribed fire.”

So far the drought isn’t raising consumer prices, but that’s likely to change. In the meantime, ranchers and dairy producers are getting squeezed financially by higher costs — and are left with dwindling options.

“You’re going to have to cull your cattle,” said Tracy Schohr, a rancher and livestock advisor for UC Cooperative Extension in Quincy. “You’re going to have to make decisions about which cattle to sell.” Her ranch sold 15 animals earlier this year.

Humans are the cause of most wildfires. Climate change will make that worse
(The Hill) Zack Budryk, July 24

…“While it hasn’t gotten as much study, it would also appear that there’s an increase in the number of red-flag days, or the number of days affected by high-wind incidents,” according to Sabrina Drill, the natural resources adviser for University of California Cooperative Extension in Los Angeles and Ventura counties.

These conditions can be particularly dangerous in Southern California, where the majority of fires are driven by drifting embers, she added. In addition to spreading individual fires, she noted, high winds can increase the rate at which moisture in vegetation evaporates. The couple whose gender reveal ignited the San Bernardino County fire were unable to extinguish it with water bottles due to the high winds present at the site.

“That’s also why during big wind events we have a lot of these power companies actually shutting power off,” said Max Moritz, a cooperative extension wildfire specialist at the Bren School, UC Santa Barbara.

“We have good science that shows homes retrofitted or built this way are more likely to survive forest fires,” said Susie Kocher, forest consultant at the University of California Cooperative Extension.

Landscape changes can also make a difference. Fire experts think in terms of the 0-5 zone, which refers to the five feet of circumference around a house. This zone should be kept free of debris, firewood, plants, or mulch. “It looks nice to put a bush under our window, and that’s exactly the wrong thing to do,” says Ms. Kocher.

The number of controlled burns is rising in California. Is it enough?
(SF Chronicle) Yoohyun Jung, July 17

…The public’s perception of prescribed fires has shifted in the past five to 10 years, said Lenya Quinn-Davidson, fire adviser with the University of California’s Cooperative Extension and director of the Northern California Prescribed Fire Council. There’s an increased acceptance of their value as a tool to reduce fire risk.

“People in general are tired of scary fire season after scary fire season,” she said. The public is desperate for a solution and rethinking what’s working versus not, and community members — not just fire agencies — are increasingly getting involved in prescribed fire efforts by joining and forming associations, of which there are 13 now in California, she said.


Wildfires Are Intensifying. Here’s Why, and What Can Be Done
(New York Times) Winston Choi-Schagrin, July 16

By nearly every metric, the wildfires in the Western United States are worsening. They are growing larger, spreading faster and reaching higher, scaling mountain elevations that previously were too wet and cool to have supported fires this fierce.

“We have good science that shows that homes that have been retrofitted or built in this way are more likely to survive wildfires,” said Susie Kocher, a forestry adviser with the University of California Cooperative Extension.

… One of the directions in which AI innovations are aimed is the speeding up of genetic crop selection. However, the vice president for UC Agriculture and Natural Resources, Glenda Humiston, claims that the implementation of AI in agriculture faces many difficulties due to the high variability of environmental conditions across a single field. The detection and analysis of all those conditions require the use of sensors, complex algorithms, and advanced data processing all together to enable smart decision-making in farm management.


UC Berkeley study finds marijuana farms require less water than previously assumed
(The Daily Californian) Kavya Gupta, July 14

Researchers looked into farms in Northern California, including those in Humboldt, Trinity, Mendocino and Sonoma counties. Their findings found that earlier assumptions about marijuana production and water use had been misinformed by incomplete data. Earlier studies did not take into account differences in growing conditions, temporal variation and water storage.

According to Van Butsic, campus assistant cooperative extension specialist and one of the study’s researchers, legal marijuana production is generally sustainable, given that stored water is used.

More catastrophic fires in California - can Australia's prescribed burning help?
(Australia Broadcasting) Linda Mottram, July 12

Another catastrophic fire season has begun in the western United States. Multiple, massive blazes are raging in several states, some defying fire fighting efforts, as temperatures soar above 50 celcius in places, in tinder dry, prolonged drought conditions. Lenya Quinn-Davidson, Northern California Area Fire Advisor with the University of California Cooperative Extension, says climate change is driving fire seasons that some estimate are about 70 days longer than in the past. But she says is 100 years of keeping fire out of fire-adapted and fire-dependent ecosystems, allowing fuel buildup, which feeds worsening seasons. She says active management of the system, including prescribed burning on the Australian model, and better building and planning are vital tools to ameliorate the impact of wildfires.

Connecting Ranchers with Land Stewards Could Be Key to Less Disastrous Wildfires
(Civil Eats) Anna Guth, July 8

…“I finally said, ‘Enough!’ [We’ve had] four catastrophic fires and we’re not doing enough with the livestock owners in the areas where vegetation has grown back to continually manage it,” said Stephanie Larson, who directs the University of California Cooperative Extension in Sonoma County and served as a consultant to the Fitch Mountain project.

… Sheila Barry, a U.C. Extension livestock and natural resource advisor and a contributor to the cattle study, highlighted that as long as land managers use practices, such as rotational or “managed” grazing—which involves regularly rotating the animals between separate pastures or “paddocks”—there can be myriad additional ecological benefits besides addressing wildfire. Barry’s research has shown positive impacts for special status species, such as the California Condor. She also found evidence that the managed grazing can help control non-native plants, providing habitat for pollinators, and sequestering carbon.

…Scott Stephens, a forestry professor at UC Berkeley is seeing evidence of that firsthand in the Plumas County town of Quincy, where he’s teaching a summer field course for undergraduates.

He said after several weeks of temperatures above 90 degrees, plants there are “already showing signs that look like August: leaves starting to shrivel, shutting shut down because moisture is being depleted by the heat.”

“The hot temperatures plus the combination of two years of below average precipitation this year is really worrisome because that lower moisture is going to make fire behavior more extreme, spread rates more extreme,” he said.


Study Shows Growing Cannabis Uses Less Water than Previously Thought
(High Times) AJ Herrington, July 8

A study from the University of California Berkeley Cannabis Research Center has determined that licensed cannabis cultivation operations use less water than previously thought.

Fear as the East Bay hills fill up with dead and dying trees
(SF Gate) Katie Dowd, June 21

… Drought and parasites may be intersecting to exacerbate the crisis. by UC Berkeley Department of Environmental Science, Policy and Management adjunct professor Matteo Garbelotto attempted to determine what is causing the "highly unusual" spate of deaths among acacia trees. Garbelotto found the presence of two fungi, Diaporthe foeniculina and Dothiorella viticola, at all the Bay Area sites he studied. 

"They both start as endophytes, living inside trees without any obvious effect on tree health," the study found, "then often become pathogens — some relatively aggressive — in conjunction with the onset of predisposing stress factors (drought, heat stress, fewer foggy days, competition due to high stand density) and then survive as saprobes on the wood of the dead trees."

(Sacramento Bee) Zaeem Shaikh, June 17

According to the University of California Cooperative Extension, it’s important to dig down a few inches to see if the soil is drying, and check out signs of too little water — such as when your lawn retains a footprint for several minutes. Make sure to water deep, write Janet Hartin and Ben Faber from the Cooperative Extension.


What is causing meat prices to rise?
(KRON4) Noelle Bellow, June 16

…“Beef prices have bene relatively cheap for a while, and now they’re not at all.”

Professor of Agricultural Economics at UC Davis Daniel Sumner says the seasonal increases will always come and go, but this year most of the increase you’re paying for has to do with the cost and demand for corn and soybeans.

“Its supply and demand fundamentals in a worldwide basis.”

“Underlying is the price of corn and soybeans. What does a steer eat? Corn and soybeans. What does a pig eat? Corn and soybeans. And those crops have gotten more expensive in part because of demand from China. They don’t produce a lot of that in China, they’re willing to pay for it so there they go. So that demand you and I see is when we go to the Costco or other super market.”

Professor Sumner also points to slower production lines at meatpacking plants following the pandemic, but he’s confident prices will moderate soon.

“Within a month or two, we’ll see some moderation “I’m thinking.”


Oregon governor signs bill to explore liability changes for prescribed fire
(Capital Press) Sierra Dawn McClain, June 14

Prescribed fire, also known as “planned,” “Rx” or “controlled” fire, is a fire set intentionally to limit hazardous fuels on the landscape — for example, by burning brush under trees in the spring to prevent a larger wildfire in the summer or fall.


There’s a danger in over-simplifying Calif. water conservation
(Western Farm Press) Jeannette Warnert, June 11

Wintertime flooding in permeable areas is one way groundwater can be recharged as it is used during the dry season. Getting access to water, developing infrastructure and flooding large farms will allow water to seep back into aquifers. Small-scale farmers can also be involved, said Ruth Dahlquist-Willard, the UC Cooperative Extension advisor to small-scale farmers in Fresno and Tulare counties.


Extension services are the best free cooking resource
(Washington Post) Becky Krystal, June 10 

Julie Garden-Robinson, vice president for awards and recognition at the National Extension Association of Family & Consumer Sciences, says people in her line of work call themselves “the best-kept secret.”

“We don’t want to be a secret,” she says. “We want people to access our resources.”

Formally established by an act of Congress in 1914, extension programs are based at land-grant colleges and universities and tasked with providing informal, research-based education to agricultural producers, business owners and the general public on a wide variety of topics, from parenting and gardening to cooking and food safety.


Groups: Align Calif. workplace regs with CDC guidelines
(Western Farm Press) Time Hearden, June 9 

Western Growers has teamed with a handful of business and restaurant industry groups in California to ask Gov. Gavin Newsom to align coronavirus-related workplace regulations with current guidelines from the U.S. Centers for Disease Control and Prevention.

The groups urge Newsom to issue an executive order which aligns physical distancing guidelines with a planned June 15 "reopening," provides safe harbor from fines and penalties for employers who act in good faith, and removes a requirement for stockpiling N-95 respirators.

Western Drought Forces Farmers to Make Tough Decisions
(Modern Farmer) Shelby Vittek, June 7

… Conditions are especially dire in California, where 41 of 58 counties are under a drought state of emergency. This year’s drought is similar to years past, with one caveat, says Dan Sumner, UC Davis professor of agricultural and resource economics and director of the UC Agricultural Issues Center. “Sonoma County has been hit more this time,” he says, “and that is less common.”

…UC Davis’ Sumner says it’s not time to worry just yet. “It could become more severe, but that is a few years away,” he says. “Droughts in California have been part of agriculture for a very long time…California is a wonderful place for many crops and that has not changed at all.”


Legislature rejects mill fee increase, restores UC ANR funding
(Agri-Pulse) Brad Hooker, June 4 

Budget committees for both houses this week rejected a proposal by the governor to replace the pesticide mill assessment with a tiered system that penalizes toxicity. The Legislature would instead provide two years of bridge funding for new pesticide monitoring and outreach programs.

The committees also rejected the governor’s proposal to remove a budget line-item for UC Agriculture and Natural Resources. Instead, they offered to boost the division’s budget by $32 million. This would fill 120 positions for academic advisors and specialists and support extension programs.


5 Ways to Save and Cool the Planet
(Marin Independent Journal) Marie Narlock, June 4 

When it comes to water consumption, plants come in low, medium and high. At the highest end is lawn, which gulps water precipitously. If there’s one plant to replace or reduce, make it your lawn. (Marin Water and North Marin Water District are paying customers to remove their lawns.) Grow California native plants or other species that are low on water and high on ecological value. Go to the UC Marin Master Gardener website to learn about plants that need little or no water once established, plus instructions for replacing your lawn.

"Given that this is the first grant program of this nature administered by the County, we were not sure how many applications we would receive," said Caryl Hart, former interim General Manager of Ag + Open Space and county lead for the vegetation management program. "The sheer amount and quality of the applications we received is a clear indicator of the need and desire of the community to reduce fire risk across the county; and we look forward to working with those applicants that were not awarded funds during this cycle to address vegetation management concerns through other funding and technical assistance channels, and to encourage them to apply for the next round of County funding."


Livestock owners face tough choices amid water shortages
(AgAlert) Ching Lee, June 2

…Lack of rain has shorted not just forage for grazing but the silage dairy farmers grow, with some estimating about a 50% loss on their crop, said Randi Black, a University of California Cooperative Extension dairy advisor for Sonoma, Marin and Mendocino counties. Because silage remains "such a good feed source" for milking cows, she said loss of the crop could reduce milk production and, therefore, dairy farmers' milk checks.

With more livestock owners needing to buy hay, the market has become "incredibly competitive," Black said. Some dairy farmers have reported paying about $100 more per ton compared to last year for quality lactating-cow hay. Plus, many farmers have incurred new costs of hauling water, with estimates of around $15,000 per month to pay for water and for labor and diesel to haul it, she added.


A Tiny Pest, a Big Crossroads for California Citrus
(Civil Eats) Anne Marshall-Chalmers, June 2

… “It’s a pretty nasty vector,” says Matt Daugherty, a cooperative extension specialist at the University of California, Riverside. “Their populations can get roaring pretty quick.” A female psyllid can lay 500 to 800 eggs. In a sinister twist, psyllids that do not carry HLB are attracted to infected trees, Daugherty says, conversely those that are infected tend to prefer healthy, uninfected trees. And in California, citrus is everywhere, with trees lining farmland and dotting residential yards. “That’s bad luck on our part,” he says.

… Neil McRoberts, a professor of plant pathology at UC Davis, says that California’s climate may impede the psyllids’ ability to spread the disease. “Winters are colder than they like. Summers are hotter and drier than they’re used to,” he explains. But that climate is changing. Temperatures are trending hotter in California, and that could mean increased pest populations, and an increased reliance on pesticides.

Landowners team up to fight wildfires — with fire
(E&E News) Kylie Mohr, June 2

After watching Nebraskan farmers and ranchers team up to do prescribed burns on their fields, Lenya Quinn-Davidson was hooked on the idea of pooling resources as a way to get fire back on the landscape out West.

She and other advocates for prescribed fire in Northern California formed a group to conduct burns on private land. As word spread, interest skyrocketed.

"Our phones were ringing off the hook," said Quinn-Davidson, an area fire adviser with the University of California Cooperative Extension (UCCE) and director of the Northern California Prescribed Fire Council. "We were evangelizing this prescribed burn association model."

Amend The Soil, Or Not To Amend?
(My Motherlode) Rebecca Miller-Cripps, May 16

We all “know” that to help our plants grow we need to amend poor soil, right? Well, maybe not… In a recent article from the University of California Agriculture and Natural Resources (UCANR) Green Blog, author Jeannette Warnert quotes UC advisors who recommend against it. So, do we amend soil when planting or do we not? As we were taught during Master Gardener training classes, the process of gardening is rarely straightforward and the answer is often “it depends.” That is the case with soil amendments.

“Corn takes land away from wheat. Well, that reduces wheat supply, and you increase the price of wheat as a consequence,” Sumner said.


Kern Farmers Make Do Under Drought Conditions
(The Bakersfield Californian) John Cox, May 9

Kern County ag producers are making changes big and small — from redeveloping entire orchards to fine-tuning their irrigation systems — as they try to adjust to worsening drought conditions across the Central Valley.

Strategies vary depending on access to water and ability to shift irrigation to different fields. Some landowners are trying to hold onto as much water as they can in case prices rise later in the year.

Is growing weed sustainable? The answer is complicated.
(Pop Sci) Shaena Montanari, May 6 

… Studying cannabis is important because it isn’t lumped in with traditional agriculture as far as regulations go, says Van Butsic, study author and Cannabis Research Center co-director. “One of the reasons why we do research on cannabis is because it has a sort of unique and separate social and cultural history than other agricultural crops,” he says. 

… Quantifying the overall environmental impact of cannabis cultivation is difficult because of illegal or trespass farming done without state permits. It is difficult to quantify how many illegal farms there are in any state. Still, in northern California, Butsic says, it is a lot. “In northern California, where we’ve done the finest grain research and the most research, over two-thirds of the farms are not permitted,” he says.

Bridging Intention and Outcomes
(JD Supra) May 5

On March 24, 2021, the Groundwater Resources Association of California and California Groundwater Coalition hosted the virtual 2021 Groundwater Law & Legislation Forum, featuring a keynote address from California’s Natural Resources Secretary Wade Crowfoot and updates on pending groundwater legislation, DWR’s SGMA implementation, and ACWA’s position on potential bond measures.

…As Ruth [Dahlquist-Willard, a small farms advisor for the UC Cooperative Extension who works primarily with immigrant, refugee and other farmers with limited resources] eloquently put it during the discussion, “when using a macroeconomic lens, many of the small-scale stories and impacts get lost, and it typically hurts the communities that are most vulnerable to these impacts.” Not all outcomes and impacts are easily comparable nor quantifiable. A proportionally equivalent impact of say net water allocation or reduction for two stakeholders could very likely have drastically different implications for those entities. While a larger entity may be able to absorb a change with efficiencies and scale, a smaller entity may have no further wiggle room or funding to make the required adjustments.


Why the hate?
(High Plains Journal) Kylene Scott, May 5

… I just can’t get past the fact some people believe they can thwart climate change. You can’t eat your way out of changes in the environment. Alison Van Eenennaam probably said it best in the April 28 pre-conference event for the Animal Agriculture Alliance’s Obstacles to Opportunities virtual summit.

“I think that it's—do you want intensive production systems with low land use and greenhouse gas emissions per unit of product or extensive systems? Which maybe have the opportunity to also capture carbon. And here again, my friend (Hanna Tuomisto) is making the argument that livestock production especially extensive cattle grazing maintains habitats and species and is therefore really important for biodiversity and so, eliminating all livestock is really not reasonable from the perspective of biodiversity conservation, and perhaps most importantly, is that livestock are a hugely important role in sustainable ag systems as nutrient recyclers, and up cyclers, and their ability to utilize plants and other food that humans cannot consume.”


New Podcast Targeting California Cattle Producers
(CalAg Today) Tim Hammerich, May 5

Attention cattle producers and enthusiasts. The University of California Cooperative Extension has launched a new podcast just for you: CattleCal. That’s “Cal” with only one “L”, is targeting both beef and dairy producers and will be hosted by assistant feedlot management extension specialist, Pedro Carvalho.

Carvalho… “The focus of my job is the feedlot producer, but the podcast is not only focused on the feedlot producer. There are a couple of series that are going to be focused on people who work in agriculture in general. So we have two episodes that we bring a guest to our podcast and we do two episodes with that person. One is that person just to talk about their career, where they're from, what they have done, how they started working with cattle. What they are doing in their current job. Things that they learned during that undergrad and grad school process and things that they are learning still today. So that's something for maybe for undergrads, people who are deciding to go into an ag career or something like that. It's also good for producers because we always learn listening to people's stories.”

Several Factors Contributing to Wider Adoption of Agtech Innovation
(AgNet West) Brian German, May 4

Agtech innovation is continually evolving, making more advanced tools available for farmers and ranchers. Although a slow process, farmers and ranchers have been more receptive to adopting automation and mechanization in their operations. Cooperative Extension Specialist and Weed Scientist with UC Davis, Steve Fennimore said that several factors come into play as to why agtech adoption has grown.

“There are a number of trends that are contributing to this,” Fennimore explained. “I think age and demographics of the decision-makers in ag, and I think people are getting more comfortable with this, that’s probably driving a lot of it. There are reasons to cut costs, increase your reliability and resilience and as well people don’t want to be left out.”

The COVID-19 pandemic has wrought disaster upon small businesses and the people and communities dependent upon them, with Fortune estimating over 100,000 businesses closing. Even before 2020, the forces of high finance, competition from corporations and smartphone apps were pressing on small businesses, according to Keith Taylor, UC Cooperative Extension specialist. But promising solutions exist.


California ‘burn bosses’ set controlled forest fires. Should they be safe from lawsuits?
(Sac Bee) Ryan Sabalow and Dale Kasler, April 22

…Generally, burn bosses working for Cal Fire and the U.S. Forest Service are protected if something goes awry. But private bosses, working primarily on private land, face the prospect of litigation if a fire gets out of control, said Lenya Quinn-Davidson, who heads the Northern California Prescribed Fire Council.

…Quinn-Davidson said the problem isn’t just liability, “it’s also perceived liability — people are scared to get involved in prescribed fire. Escape rates are very limited but for the private practitioner who wants to get involved in this work, it’s a barrier.”


California Extension stations face irrigation curtailments
(Farm Press) Todd Fitchette, April 22

California farmers aren't the only ones suffering with zero water allocations this season. The research efforts they rely upon from Extension programs will also be hurt as two University of California research stations have been told not to expect surface water deliveries and others may suffer similar water woes this year.

… "We can't do anything with zero water," said Rob Wilson, director of the Intermountain REC.


California's droughts sometimes make better wine - but they're bad for the industry overall. Here's why
(San Francisco Chronicle) Esther Mobley, April 21

…“Our water footprint is awfully low compared to other crops, and grapes are more drought resistant,” says [Kaan] Kurtural [an associate specialist in cooperative extension in viticulture with UC Davis]. Whereas almonds need about 4 acre feet of water to grow in California, he says, grapes demand only about 1 to 1.5 acre feet.

We Need to Talk About the Enviornmental Impact of Marijuana
(InHabitat) Grae Gleason, April 20 

To further illustrate the importance of decriminalization, JSTOR Daily enlisted Van Butsic, co-director of the Cannabis Research Center at the University of California Berkeley. As Butsic explains, “There are lots of technologies that capture VOCs before they enter the atmosphere that are required in other industries like gas stations.” But, “before [emissions] standards can be set for cannabis, we need recognition of the issue and long-term data to develop regulatory statutes—and we’re a long way from that because federal prohibition has hindered research and we don’t have the science yet.”


The Los Angeles River’s overlooked anglers
(High Country News) Miles Griffis, April 20

…“Most tend to think the quality of the water in the Los Angeles River is poor, but it’s fairly clean water,” says Sabrina Drill, natural resources advisor for the University of California Cooperative Extension. While toxicity varies by species and location on the river, a 2019 LA River report found that a person can safely consume 8 ounces of common carp, bluegill, and green sunfish, up to three times per week. Still, Drill did not recommend this, since most of the studies contained small samples.


'Dry fallowing' ground may aid in weedy rice control
(Farm Press) Todd Fitchette, April 20

…Managed fallowing can help with some varieties of weedy rice, according to Whitney Brim-DeForest, Extension rice advisor with the University of California. This is a practice that still uses irrigation water but does so on a more limited basis than if fields were planted to common rice varieties. During the last multi-year drought period a few years ago she said some growers left fields unplanted for more than one season to get a handle on weedy rice populations. That seemed to work for them.


Is California suffering a decades-long megadrought?
(LA Times) Alex Wigglesworth, April 18

… Annual droughts are also nothing new. “You will have these dry years and then in between you will get these really, really wet years,” said Safeeq Khan, assistant cooperative extension specialist of water and watershed sciences at the University of California Division of Agriculture and Natural Resources. “They can be what we describe as drought busters.”

… “From a water supply aspect, that ended the drought,” said Doug Parker, director of the California Institute for Water Resources at UC Agriculture and Natural Resources. “From an ecosystem aspect, I don’t think our forests and our natural lands that rely on rainfall ever fully recovered from that drought, and now we’re into the next one.”

…Groundwater supplies also take years to rebound, said Hoori Ajami, assistant professor of groundwater hydrology at UC Riverside, who is part of a team of researchers that analyzed data from wells impacted by climate for a paper currently in peer review.

“Once your precipitation has recovered, that doesn’t mean your stream flow is recovered or your groundwater is recovered,” she said. “Our estimate is it could take for groundwater between three to 10 years on average to recover.”


Drought adds pressure on Central Valley farmers as other factors cause food prices to rise
(ABC 10) Luke Cleary, April 16

…Snowpack statewide is only at 59% of its April 1 average, based on electronic measurements according to the California Department of Water Resources. Farmers in the Central Valley producing water-intensive crops such as almonds and tomatoes are already facing some difficult choices. 

"It's really serious, particularly in the Central Valley," said UC-Davis Agricultural Economist Daniel Sumner. 

"The cost of water, the scarcity of water adds into all the costs of food throughout the system," Sumner said. 


Why Wall Street investors’ trading California water futures is nothing to fear – and unlikely to work anyway
(The Conversation Ellen Bruno) Heidi Schweizer, April 15

… As the economics of water resources, we believe there are many benefits of a well-functioning water futures market, especially as climate change&nbsp makes the amount available for use increasingly hard to predict. The market’s main purpose, after all, is to provide protection for California water users – such as farmers and cities – against fluctuations in prices.

While there are real risks, we think they’re misunderstood and overblown. And anyway, very few are actually trading water futures.


California Dreaming: Artificial intelligence and robots are helping farmers prepare for climate change crisis
(ABC 7 Los Angeles) Juan Carlos Guerreo, April 14

…"Suddenly we can control the environment in ways we never thought possible," said [Gail] Taylor [chair of the Plant Sciences Department at UC Davis]. "Part of the bigger mission of the University of California is to breed resilient crops for the future, crops that can tolerate higher temperatures and crops that don't need so many chilling days in the winter."


Ventura County Compost Cup Competition April 16-19
(VC Reporter) David Goldstein, April 14

… Dr. Ben Faber, Ventura County Farm Advisor with the University of California Cooperative Extension, evaluates compost through analysis of nutrient values. As. Faber noted, however, people familiar with compost can often detect good compost through smell, “There is nothing better than good smelling compost!” 


With Wildfire Season Looming, Early Budget Action Is A Welcome Start
(California Forward) Deb Kollars, April 13

…“Investing in forest management is a win-win-win-win,” said Glenda Humiston, vice president of UC Agriculture and Natural Resources and co-lead of the California Economic Summit’s Empowering Resilient and Productive Landscapes work group. “Not only do we help reduce fire risk, but we can also protect air and water quality, manage gas emissions, and infuse our economy with innovative wood products, while also training a workforce that will be vital in helping us manage our forests well into the future.”


Unwelcome and tough to evict: California’s costly, uphill battle against invasive species 
CalMatters) Julie Cart, April 12

…Funded by about $500,000 in federal grants, Ted Grosholz, a professor and ecologist at the UC Davis Department of Environmental Science and Policy, has spent more than a decade trying to evict green crabs from the lagoon. 

…Grosholz is almost admiring when he describes the characteristics of European green crabs that allow them to thrive wherever they wash up. “It has a suite of traits that make it a good invader,” he said. “They are physiologically tougher than a lot of other crabs. They are more tolerant of variable salinity. They are very tolerant of terrible conditions.” 


UC ANR Strategic Plan Serves as Roadmap for Future Success
(AgNet West) Brian German, April 9 

The 2020-2025 Strategic Plan from UC Agriculture and Natural Resources (UC ANR) helps to serve as a roadmap for accomplishing ambitious goals moving forward. UC ANR Vice President Glenda Humiston said the plan helps the department carry out its overall mission. A multi-year framework is established through the plan, enabling UC ANR to prioritize programs and resources to better serve the state.

“The strategic plan really gets into criteria, milestones, budgets, people, who’s responsible for what, and how we’re actually going to get it done,” Humiston explained. “I think that’s critical because having that kind of specificity helps to ensure that we are getting the job done.”


Weather, Wildfire and Wine: Challenges Facing California Wineries

Join us on ARE Discussions where Aaron Smith (Deloach Professor of Agricultural and Resource Economics, UC Davis) will provide an overview of the challenges facing the wine industry and Walt Brooks (Brooks Family Vineyards and Napa Valley Grapegrowers Association) will provide industry insights and on-the-ground perspectives from Napa County.


Lush Urban Forests Can Help Communities Fight Climate Change
(Enviornmental News Bits) Laura B., April 7

Urban trees are much more than lovely greenery and stately landscape features. Scientists believe trees are a key tool for combating climate change and living with warming temperatures in California.

UC Cooperative Extension is bringing together municipal and nonprofit organizations, homeowners associations, contractors, the green industry and educators to increase the tree canopy in urban areas by planting recommended species. Nearly 200 people gathered online in March 2021 to share research results, accomplishments and tree canopy growth strategies at the “Trees for Tomorrow Start Today” workshop.

If you see western subterranean termites swarming in the spring, from now through June, save the specimens for University of California Urban Integrated Pest Management (IPM) advisor and urban entomologist Andrew Sutherland.

…“A major taxonomic question surrounding western subterranean termites remains unsolved,” said Sutherland, the Urban IPM Advisor for the San Francisco Bay Area. 


7 foods you should be storing in the freezer, including yeast, nuts and peppers
(WaPo) Becky Krystal, April 5

…Nuts: If you’ve ever grabbed nuts out of the pantry and they didn’t taste right, it’s probably because they’ve gone rancid. Ditto nut flours. Nuts are packed with fatty oils, which are prone to going off, especially in warmer temperatures. According to this handy guide from the University of California Agriculture and Natural Resources folks, rancid nuts are not unsafe, but they aren’t particularly pleasant to eat. The guide recommends that if you know you won’t be using nuts within a few months, cold storage is best. Refrigeration extends the storage life to a year, the freezer, on average, to two. Frozen, shelled pistachios will last the longest (at least three), followed by walnuts and pecans (at least two), then almonds and chestnuts (at least a year). Shelled nuts are susceptible to picking up flavors and moisture, so store in something clean and airtight.

North Redlands residents can get free trees
(Redlands News) Dina Colunga, April 1

… The project was conceptualized a few years ago when Janet Hartin, an environmental horticulturist with the University of California Division of Agricultural and Natural Resources, researched multiple natural resource areas, including climate readiness of landscaping and street trees installed by cities. Part of Hartin’s research revealed significant gaps in urban forest in cities across California. She responded by creating a step-by-step process to engage residents in collaborating with agencies to select and install species that both add to canopy cover and are resilient to rising temperatures and increasing pest presence. Hartin said the North Redlands project is about getting trees into the ground in a place where the urban tree canopy is lacking.


Almond Update: Spider Mites the Focus of Next Training Tuesday
(AgNet West) Taylor Hillman, April 1

Mites can be a frustrating issue for almond growers. Research over the last several years has identified a shift in what producers need to do in order to manage the pest. “It used to be that predatory mites were the main beneficial arthropod out there helping to control mites but that has changed,” UC Cooperative Extension Advisor David Haviland said. “Almond growers have gotten a lot greener. They’ve gotten away from the organophosphates, particularly in the dormant season. As that’s gone, pyrethroid has gone down. We’ve seen a big shift in the natural enemies for spider mites.”
