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.

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.”

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.

… 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.”

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.

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.

Poor maintenance of a fruit tree could result in less fruit.

“You could see a decline in yield of anywhere from 30% to 75%,” Day said. “And your fruit will be small with a low sugar concentration.”

Growers reported the beetles in September to Jhalendra Rijal and his team at the University of California Agriculture and Natural Resources....

"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.

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.

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.

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.”

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.

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 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.

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?’”

‘Love for gardening’: UC Master Gardeners Winter Series Workshop begins
(The Appeal-Democrat) Jeff Larson, Jan. 22

Despite the rainy conditions on Saturday, the University of California Master Gardeners opened their local Winter Series UC Master Gardener Learning Garden three-part workshop to provide knowledge on the winter crop growing season and offer gardening advice for anyone looking to hit their backyards this spring. 

Part one covered three topics, according to UC Master Gardener Assistant Terri Hutton. It started with building raised gardens and how to correctly conduct hot, cold and worm composting, Hutton said.

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.”

Dr. Wendi Gosliner - Food Policy & Health Disparities Researcher
(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.”

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.”

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.

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.

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.”

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.

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.”

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.”

Why some people think California’s cow manure methane plan stinks
(LA Times) Tony Briscoe, Dec. 5

…The state Air Resources Board allows for digester operators to be paid for the amount of dairy methane they capture and burn. In 2022, that state program doled out more than $568 million to dairy- and swine-biogas operations in California and elsewhere, according to Aaron Smith, a professor of agricultural economics at UC Davis.

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.

… 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?

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.”

“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.

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.

Learning on the vine: Family-friendly pumpkin patch is sown from the seeds of education
(TimesOC) Sarah Mosqueda, Oct. 12

Families combed the rows of a naturally grown, mature pumpkin patch in Irvine for the perfect gourd last weekend at South Coast Research and Extension Center’s annual Pumpkin U-Pick event.

“Typically we do a pumpkin patch every year, but this year we did things a little differently in that we invited all of the programs that are headquartered here,” said Jason Suppes, a community educator specialist at South Coast REC.

… “Our whole goal is to conduct research, but then to also extend that information,” said Darren Haver, director at South Coast REC. “These are our community outreach programs that make sure we engage with the public.”

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.

…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.

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

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. Valliere, professor of plant sciences at UC Davis.

Commentary: Supporting agriculture and our rural communities
(Ag Alert) Alexis Zaragoza, Keith Taylor, Aug. 9

Agriculture is the lifeblood of California’s rural communities, and a thriving rural California is essential for the success of 21st century agriculture. These days, strengthening the economic future of farming and supporting the well-being of communities increasingly rely on access to technology. That calls for making new agricultural technologies available and expanding broadband in rural areas to help the farm workforce and farm families.

…That’s where the University of California Agriculture and Natural Resources’ new community economic development programming comes in.

Wild, weird and iconic, California’s Joshua tree faces a new threat: fire
(Washington Post) Reis Thebalt, Aug. 6

…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.”

…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 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.

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."

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.”

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.”

'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.”

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.”

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.”

(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.

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.

Genetically edited pork Has entered the food supply
(Ambrook Research) Jesse Hirsch, May 18

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.”

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.

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.

...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.

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.

… 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.”

Tuolumne County Volunteer Fair: Why volunteering is beneficial
(Union Democrat) JoLynn Miller, March 30

… Volunteering is part of the fabric of our nation. From the very beginning, community members banded together to help each other out. 

… Volunteering could serve as a path to employment, not only for teens and young adults, but for others trying to re-enter the workforce after time off. The Corporation for National and Community Service (CNCS) states that volunteers have a 27% higher chance of finding a job after being out of work compared to those not volunteering.

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?

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.

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.”

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.

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

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.”

…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.”

California Lurches From One Climate Extreme to Another 
(Voice of America) Steve Baragona, Jan. 25

Helen Dahlke, UC Davis hydrology professor: "Dry air that is warmer will try to suck out more moisture from the ground, and that means you know our precipitation we get in California may not reach as far as it used to. So it takes more precipitation to wet up the soils again, to wet up the vegetation."

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.”

…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.

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.

‘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?

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.”

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.

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.”

This California startup says it can predict where wildfires might start—it’s using that power in a surprising way
(CNBC) Annika Kim Constantino, Nov. 7

…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.

Supervisors approve emergency resolution on tree mortality across Mendocino County
(The Mendocino Voice) Kate Fishman, Nov. 4

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

…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.

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.”

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

“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?
(New York Times) Jesse Hirsch, Sept. 23

…“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
(& The West, Stanford University) Zack Boyd, Sept. 15

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.

The low numbers of women in the firefighting industry is a result of many things—one being a toxic work environment. Quinn-Davidson says a lot of sexual harassment and discrimination has taken place within the fire industry.

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.? 

Oberholster, of the University of California, Davis, could only tell them: "Maybe."

… One sunny and warm day in November 2021, UC Davis viticulture researcher Kaan Kurtural leads us to a plot of vines at the Oakville Experimental Vineyard in Napa Valley, nestled between the forest-coated hills near other, commercial vineyards. Since 2016, Kurtural and colleagues have been monitoring 16 unique combinations of rootstocks and Cabernet Sauvignon clones to learn which combinations are most resilient under stressful conditions like heat waves and drought while still producing high-quality Cabernet Sauvignon grapes.?

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.

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.

Citrus risks unclear from virus ID'd in Tulare

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.

“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.”

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.”

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.

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.”

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.

Benefield: Bird lovers instituting safety measures in face of avian flu
(Santa Rosa Press Democrat) Kerry Benefield, Aug. 3

“Everything is pointing to another huge outbreak,” said Maurice Pitesky, UC Cooperative Extension poultry specialist in the School of Veterinary Medicine at UC Davis.

The last major outbreak was in 2014 when more than 40 million birds were lost.

...Pitesky recommends backyard chicken coops be covered with impermeable materials, bird baths emptied and feeders put away.

The idea is to make property less attractive for migrating birds to stop. Or poop.

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.

Supervisors approve proposed countywide water resource team, with caveats
(Mendocino Voice) Kate Fishman, Aug. 2

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....

Turf: Zoysia plugs or Miniclover?

Retailers of these grass varieties tout their ability to stay greener longer while using less water and requiring less mowing than other lawns. In these ways, both grasses beat tall fescue, which the Cooperative Extension's Jim Downer says has long been standard for Ventura County lawns.

But Miniclover wins over Zoysia, partly because planting Zoysia is a lifetime commitment....

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.

Rob York, a professor and cooperative extension specialist at forests operated by the University of California, Berkeley, said the forest service’s plan could be helpful but would require extensive followup.

“To me it represents a triage approach to deal with the urgent threat to giant sequoias,” York said in an email. “The treatments will need to be followed up with frequent prescribed fires in order to truly restore and protect the groves long-term.”

PRESCRIBED FIRE–Imagining a balanced future
(International Association of Wildland Fire) Lenya Quinn-Davidson, July 20

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.”

…Last summer, in a series of articles in the journal Ecological Applications, fire scientists Crystal Kolden of UC Merced and Scott Stephens of UC Berkeley, along with other co-authors, blasted Hanson’s scientific methods and conclusions.

… The lawsuit over the Yosemite forestry work, like others filed by Hanson and his allies, is counterproductive to what is needed to get the woods back into ecological balance, said Brandon Collins, an adjunct professor at UC Berkeley and U.S. Forest Service scientist who’s published research on wildfire issues in academic journals. “We need to really scale up how we’re dealing with these forests,” Collins said.

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. 

“I'm afraid that if it's just … through prescribed fire alone, we're not going to get that type of reduction of density that we need as quickly as we need,” he says.

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.

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.

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.

"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
(The Bakersfield Californian) John Cox, June 18

Another scientist consulting with (Brian) Kolodji on the work, Brian Marsh, a local farm adviser and Kern County director of the University of California Cooperative Extension office, expressed hope the work will point to a cost-effective alternative to what is otherwise the expensive process of capturing carbon dioxide and burying it deep underground, as has been proposed by several local oil producers.

Marsh acknowledged challenges ahead, from negotiating with industry emitters of CO2 for a steady supply of the gas from their smokestacks, to establishing a cost-efficient way of distributing it throughout sprawling orchards.

Mites were ‘right on schedule’ this spring
(Farm Press) Lee Allen, June 16

…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.

With less water allocated to farmers along the Sacramento and Feather rivers, many fields will be left bare, according to Luis Espino, rice farming systems adviser and director at the University of California Butte County Cooperative Extension.

Espino said he expects the acres of rice planted in Butte County should be about 60% to 80% of normal. But in Glenn and Colusa counties, Espino estimates only about 10% of normal will be planted.

“We expect lower acreage in 2022. We already had lower acreage in 2021,” Espino said.

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.

Three years ago, he sold his home in Cottonwood, on the Shasta-Tehama county line, for a fixer-upper nearby with holes in the floor, a shoddy electrical system and windows that wouldn’t close. This fixer-upper had two inarguable selling points: a view of Mount Shasta and water from the Anderson-Cottonwood Irrigation District, a settlement contractor.

This year, without rain, the grass where his cows forage through the winter crunches underfoot.

‘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. At the start of the pandemic, Master Gardeners were suddenly bombarded with a higher volume of calls and emails seeking gardening advice. 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.”

“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 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
(NBC Bay Area) Stephanie Magallon, April 7

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.”

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.”

…According to Faith Kearns, a scientist at the California Institute of Water Resources, the current period is driving home the fact that climate change must be integrated into water planning efforts, work that many water agencies have yet to take on.

“Water infrastructure in California and much of the western U.S. was developed during a wetter time that was assumed by many to be largely stable,” she wrote in an email. “I worry about this from an equity perspective and feel that we need to be supporting water operations in integrating climate change into all planning efforts across all water systems, in the western U.S. in particular.”

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.

UC Davis to lead $15M research into climate-change resistant wheat
(Morning Ag Clips) Emily C. Dooley, Feb. 10

The University of California, Davis, is leading a five-year, $15 million research project to accelerate wheat breeding to meet those new climate realities, as well as to train a new generation of plant breeders.

“Everything is less stable,” said Jorge Dubcovsky, a plant sciences distinguished professor who is leading the grant research. “Everything is changing so you need to be fast. You need to be able to adapt fast.”

California conservationists and farmers unite to protect salmon
(Reuters) Daniel Trotta and Nathan Frandino, Feb. 8

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.”

California pear growers have a track record of innovation, said Rachel Elkins, a semiretired pomology farm advisor for University of California Cooperative Extension in Lake County. They have developed areawide, voluntary integrated pest management programs, hosted high-density rootstock trials on trellis systems that could make orchards platform-friendly and tinkered for decades with new varieties, she said. Meanwhile, the extension office is in the process of hiring a regional diversified agricultural area advisor. That person won’t be a direct replacement for Elkins, though pomology will be among the duties.

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?’”

(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.

… 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.

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.

'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.

“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.”

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 Bay Is Rising. Newark Residents Wonder Why The City Plans to Develop Its Shoreline
(KQED) Ezra David Romero, Dec. 13

Sanctuary West could help fill in the gap for much-needed housing in the Bay Area, but scientists like Mark Lubell, who studies sea level rise and governance at UC Davis, say the proposed site “is a terrible place to put a development.”

“I think we should definitely be looking at alternative locations for regional economic development that are not in hazard areas, wetland areas or watersheds,” he said.

Controlling Psyllids in Organic Citrus Production
(Citrus Industry) Len Wilcox, Dec. 13

At the recent California Citrus Conference held in Visalia, Monique Rivera, assistant cooperative Extension specialist at University of California Riverside, presented information about management of Asian citrus psyllid (ACP) in organic citrus grown in the San Joaquin Valley.

“There is consumer demand that needs to be met for organic citrus,” Rivera said. “So there is a quick transition in the valley to organic management systems.”

UC Berkeley Research Forest Tests Strategies for Wildfire Prevention 
(NBC San Francisco Bay Area) Joe Rosato Jr. Dec. 10

…For decades, researchers [at the Blodgett Forest Research Station] have worked in relative obscurity on the land, staging scientific experiments to gauge the effectiveness of different land management strategies. But as massive fires chip away at the state's forests, the work at Blodgett is now getting far more attention.  

"I have been on this forest for 20 years, and 15, 20 years ago I couldn’t get a reporter to come here and talk about my research," said Blodgett researcher Rob York. "But now it’s very much front and center."

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.

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.”

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.

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.”

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."

The Controversial Quest to Make Cow Burps Less Noxious
(Wired) Matt Simon, Oct. 1

Animal scientist Frank Mitloehner leads me to another kind of feeder, one that could easily be mistaken for a miniature wood chipper. He grabs a handful of the alfalfa pellets that the machine dispenses when it detects that a cow has poked its head in. “This is like candy to them,” Mitloehner says. I stick my head into the machine as Mitloehner points out a small metal tube within: “This probe measures the methane they exhale, and that happens every three hours for all the animals in this study.”

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

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.

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.

…“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.”

Coastal grape growers can use less water during drought
(Sonoma County Gazette) Emily Dooley, Sept. 2

… It sheds new light on how vineyards can mitigate drought effects at a time when California is experiencing a severe water shortage and facing more extreme weather brought on by climate change, according to lead author Kaan Kurtural, professor of viticulture and enology and an extension specialist at UC Davis.

“It is a significant finding,” Kurtural said. “We don’t necessarily have to increase the amount of water supplied to grape vines.”

“They tend to gain weight at an accelerated rate, then during the school year their body mass index goes down, but not as much, so over time kids are getting more and more overweight and obese,” Ritchie said.

I’m fine. The cat in the carrier is the one complaining.”

Kocher said local agencies had done an admirable job in recent years of managing the forests in the immediate vicinity of South Lake Tahoe, eliminating some of the vegetation. But she was worried about the prospect of spot fires “that could go block to block” and burn up people’s homes.

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."

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.

Matteo Garbelotto, UC Cooperative Extension specialist:

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.

Caldor Fire's 'Explosive Growth' Following Dixie Fire's Playbook
(CapRadio) Kris Hooks, Manola Secaira, Aug 19

Rob York, an extension specialist with UC Berkeley focusing on forest ecology and management, said this excess is the result of a history of fire suppression in the area. Before suppression tactics were used, fires burned more frequently, leaving less debris on the forest floor. 

“The trees growing in the forest are in this type of environment that they haven't experienced before,” York said. “The ultimate challenge is to try to figure out how to reduce it.”

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.

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.”

Let it burn? Forest Service's new all-out fire suppression policy a dangerous move, critics say
(SF Chronicle) Kurtis Alexander, Aug. 7

…“I wish there was an easy way we could get out of this dilemma we’ve gotten into,” said Scott Stephens, professor of fire science at UC Berkeley.

Like other experts, Stephens says achieving the right balance between safety today and safety tomorrow comes only by continuing to burn proactively, when appropriate. Even before the ban, he noted that the Forest Service was very cautious about proceeding with controlled fire, making sure the burns were safe and didn’t take resources away from fighting fires.

California Walnuts: Aug. Orchard Management Considerations
(AgFax) Evie Smith, Franz Niederholzer, Katherine Jarvis-Shean, and Luke Milliron, University of California Cooperative Extension Specialists, Aug. 5, 2021

Navel Orangeworm: Begin monitoring for NOW in your orchard. Healthy walnuts are only susceptible to NOW at and after hull split. Consider preharvest intervals and duration of residual activity when considering treatment options. See the above article on IPM on a Budget for NOW control considerations in a lean price year.

California Almonds: Aug. Orchard Management Considerations
(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.

Report: U.S. walnut production could remain in check 
(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.”

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.”

Experts, UC scientists discuss wildfires in the state’s riskiest regions
(SF Examiner) July 30

…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.”

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 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.

… 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.

Reservoirs are drying up as consequences of the Western drought worsen
(WaPo) Diana Leonard, July 9

…Faith Kearns, a scientist at the California Institute of Water Resources, said many communities face chronic water supply issues that are exacerbated by drought and groundwater withdrawal.

“My biggest concern is always with ensuring that people have affordable clean water at the household level, and that ecosystems and the life they support can manage,” she wrote in an email. “It's already a struggle that will continue to worsen throughout the dry season.”

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.

Another California Heat Wave Will Bake Forests Already Primed to Burn
(KQED) Raquel Maria Dillon, July 8

…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. Researchers from the center began studying water use by cannabis growers in 2017, following the legalization of recreational marijuana in California the previous year.

… Van Butsic and Ted Grantham, co-directors of the Cannabis Research Center and adjunct fellows at the Public Policy Institute of California’s Water Policy Center, told local media that the study “hasn’t found cannabis to be particularly thirsty relative to other crops.”

“Legal, outdoor production uses about the same amount of water as a crop like tomatoes,” Bustic said.

Commentary: Legislature recognizes UCANR’s value with funding
(Ag Alert) Taylor Roschen, July 7

… But in a clear spot within the opaqueness, the Legislature has agreed to use its overwhelming resources this year and in future years to fully fund the University of California Agriculture and Natural Resources.

Ag Alert® readers, UCANR supporters and staff, and the farm community surely recognize the critical role farm advisors, specialists and community education specialists serve to help farms identify pests and diseases; implement water use efficiency; improve soil health, biodiversity and crop efficiency; adapt to climate change; and promote agricultural education. But due to significant funding reductions over the last two decades, UCANR has lost almost 40% of its program staff, leaving them reliant on fees, inconsistent grant funding and perpetuating service area deficits.

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."

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.”

There’s a danger in over-simplifying Calif. water conservation
(Western Farm Press) Jeannette Warnert, June 11

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.

UCANR Scientist Publishes Guide to Science Communication
(AgInfo Net) Tim Hammerich, May 25

When it comes down to it, many of the problems we face in our work and even personal life are often problems in communication. This is certainly true in agriculture when it comes to trying to clearly communicate the science behind how food is produced. In a new book called “Getting to the Heart of Science Communication”, UC Ag and Natural Resources Scientist Faith Kearns provides guidance on how to communicate science in a way that not just informs, but connects.

Winter Flooding of Farm Lands Could Ease Drought Impacts
(Western Farm Press) Jeannette Warnert, May 19

Helen Dahlke, professor in integrated hydrologic sciences at UC Davis, has been evaluating scenarios for flooding agricultural land when excess water is available during the winter in order to recharge groundwater.

If relatively clean mountain runoff is used, the water filtering down to the aquifer will address another major groundwater concern: nitrogen and pesticide contamination.

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.

Which rose first: the price of chicken or corn?
(Marketplace) Justin Ho, May 11

…“So China has turned to U.S. corn, and that drives prices in the United States,” said agriculture professor Daniel Sumner at University of California, Davis.

He said American farmers have been growing more corn to meet demand, so they have less room for other crops.

“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.”

Commodity Upswing Helps Alfalfa Growers but The Timing Could Be Better
(Bakersfield.com) John Cox, May 2

Only one of the county's top-10 crops — alfalfa — has benefited noticeably from recent bad weather in Brazil and strong Chinese demand for grains that feed livestock. And unfortunately for local alfalfa growers, the timing's all wrong.

Problem is, California finds itself in another drought, and because alfalfa is a relatively water-intensive crop, growers often must pay top dollar to supplement meager supplies for irrigation.

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.

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.”

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.

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.”
