Why Laguna Niguel fire was so destructive: Flying hot embers, huge homes, dry brush
(LA Times) Tony Briscoe, Alex Wigglesworth, Hannah Fry, Paul Duginski, May 13

"...once flames reached those homes, the fire began to spread from structure to structure....

“It actually creates a condition where the homes themselves become the fuel,” said Max Moritz, a UC Cooperative Extension specialist in wildfire at UC Santa Barbara’s Bren School. Similar patterns could be seen when the Tubbs fire swept through the Santa Rosa subdivision of Coffey Park in 2017 and when the Camp fire destroyed the town of Paradise in 2018, he said."


‘Chaos On The Horizon’: Concern Grows Over Potential Summer Power Outages In California

(CBS Sacramento) Laura Hefeli, May 6

…“Whenever there is a heat event, that’s when the grid is being taxed the most,” said Keith Taylor, a UC Davis professor of community economic development. Taylor said increased energy uses like blasting air conditioning or refrigeration could lead to issues.

“When you have 40 million people doing it at a time, that’s a lot of stress on the system,” he said. Taylor said the state’s lack of energy options like solar and wind, and the inability to borrow power from other states, make for a perfect storm.

“These other states are also going to be dealing with their own power shortage issue,” he said. “I think there’s going to be a limited amount of chaos on the horizon.”


A drought so bad it exposed a long-ago homicide. Getting the water back will be harder than ever
(LA Times) Corinne Purtill, May 6

…“When it starts to feel really bad is when all of those types of drought are essentially happening at the same time. And that’s kind of where we’re at right now,” said Faith Kearns, a scientist with the California Institute for Water Resources in Oakland.


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.”


As peak wildfire season looms, SB County Fire Safe Council looks to educate and prepare
(KCBX) Beth Thornton, May 4

Max Moritz is participating in the weekend activities. He is a state wildfire specialist and UCSB adjunct professor. He said educating the public is important since the Central Coast is prone to wildfires due to its chaparral landscape and sundowner winds.

“Often [fire] events are happening in what we call extreme weather conditions — so hot, dry, strong wind conditions,” he said.

Moritz said as we head into fire season, residents play a key role in reducing risks and making the community safer.

“Make sure you have defensible space around your home, so that firefighters have a place to work, and clean out the rain gutters so there’s not ignitable materials there,” he said.

California's new drought rules: will they be enough to halt the 'alarming challenges' ahead?
(The Guardian) Gabrielle Canon, May 3

Experts have called for stronger limits, as the climate crisis rapidly unfolds in the state and normal cycles of drought become longer and much more frequent.

“The water we have now is 40% lower than the worst-case scenario in the models ever predicted,” says Dr Kurt Schwabe, a professor of environmental economics and policy at the University of California Riverside. Schwabe added that he thinks the state is being too cautious about pushing agencies to do more. “We are in a new climate reality and we have to adjust more quickly than we had in the past.”

How to climate-proof your garden
(Sierra Magazine) Krystal Vasquez, April 25

Climate change “has had a huge impact on gardening,” said Missy Gable, director of the University of California Agriculture and Natural Resources program. “My own personal experience with gardening and climate change has seriously revolved around drought.” 

...Of course, this would all be easier if we could just control the weather. Sadly, gardeners don’t have that power … or do they? “We can control microclimates somewhat by where we place plants,” says Karrie Reid, an environmental horticulture adviser at the UC Cooperative Extension of San Joaquin County.

California Invests $3.75M to Fund Safer, More-Sustainable Pest Management
(Perishable News) April 22

  • …Assessing a biocontrol system for the management of tadpole shrimp in rice. Tadpole shrimp usefully eat some early season weeds but can cause damage to rice later in their lifecycle. To preserve their role in controlling weeds but diminish the shrimp’s later impact on the rice harvest, predator mosquito fish will be introduced mid-season to control the shrimp’s population when necessary. This research will be led by Dr. Ian Grettenberger at UC Davis.
  • Testing two emerging IPM technologies for agricultural use, the automatic release of biocontrol organisms using flying drones, and precision spray application technology, which uses much less pesticide than applying pesticide sprays using current techniques. This research will be led by Dr. Ian Grettenberger at UC Davis.
  • Developing an IPM software decision-making tool for pistachio growers that helps reduce pesticide use by guiding more precise pesticide applications when chemical use is necessary. This IPM tool leverages smart technology to help growers transition from routine preventative spraying to more limited threshold-based chemical use. This research will be led by Dr. Themis Michailides at UC Davis.

Research projects funded for urban and agriculture pest management:

  • Studying the use of a reduced-risk ”attract-and-kill” approach as an effective alternative to urban and agricultural pesticide spray programs for managing South American palm weevils, a pest that damages date palms in urban and agricultural environments. “Attract-and-kill” strategies use pheromones that attract the target pest to a small amount of pesticide that kills the insect, as opposed to spraying a large quantity of pesticide over an area to control pest populations. This research will be led by Dr. Mark Hoddle at UC Riverside.
  • Studying the impact and potential of using insect growth regulators that target Argentine ants for pest control in urban and agricultural environments. Insect growth regulators are new, safer pest management tools that pose a much lower risk of causing unintended damage to beneficial insects when compared to many traditional insecticides. This research will be led by Dr. Dong-Hwan Choe at UC Riverside.

Research projects funded for urban and nonagricultural pest management:

  • Testing non-chemical entrapment methods for trapping, monitoring and eliminating bedbugs, a significant public health pest that disproportionately affects low-income Californians. This research will be led by Dr.Catherine Loudon at UC Irvine.
  • Creating a new set of guidelines for effectively identifying and managing biting mites, a common, but poorly understood indoor pest that is often misidentified and incorrectly managed. This research will be led Dr. Andrew Sutherland at UC Agriculture and Natural Resources (UCANR).
  • Assessing a baiting system for detecting western drywood termites to reduce the number of unnecessary fumigation treatments in California homes, especially in Southern California where termites represent a significant pest problem. This system would indicate when active termite infestations have returned and if preventative treatment is needed, greatly decreasing the amount of high-risk pesticide use in homes. This research will be led by Dr. Dong-Hwan Choe at UC Riverside.

UCD Provides Sensory Tasting Guidelines for Evaluating Grape Smoke Exposure Effects
(Wine Business) Ted Rieger, April 18

The University of California, Davis (UCD) Viticulture & Enology Department presented an  extension seminar April 8th, "Evaluating Impact of Grape Smoke Exposure: Best Practices," with guidance to evaluate smoke sensory impacts on grapes and wines and how to train staff and tasting panels to recognize and rate smoke impacts. UC Cooperative Extension enology specialist Dr. Anita Oberholster moderated the meeting and provided basic science about smoke exposure based on current knowledge. "Grapes can have smoke exposure without having smoke taint," Oberholster said. She noted that smoke taint is not a single attribute, it can be described as smoky, burnt, tar, campfire, ashy, medicinal or earthy. For assessing smoke taint, the focus is on tasting for "ashy aftertaste" or a "lingering retro-nasal ashy character" on the palate.

In the valley, 'heat islands' of asphalt and fake lawn reach 170 degrees. What you can do
(Desert Sun) Janet Hartin, April 9

As a resident of the Coachella Valley for 32 years and a University of California Agriculture and Natural Resources academic specializing in horticulture, I’m asking for your help.

Please rethink the use of asphalt, black (dyed) mulch, and synthetic lawns in our desert communities. They are superheating what already are extreme urban heat islands. An abundance of living plants interspersed with light-colored organic and inorganic mulches that reduce soil evaporation between plants are better choices.  


Bay Area ranchers concerned as unseasonable heat impacts livestock, sales
(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.”


CA cannabis is in sticky situation despite high hopes of Prop 64
(KCRW) Mary Carreon, April 7

… “When you go back and look at what the advocates of Prop. 64 said would happen and you look at their policy proposals, they clearly over-promised, they clearly chose not to follow best business practices and fundamentals in these promises,” says Dr. Keith Taylor, a professor of extension at UC Davis who researches the efficacy of Prop. 64. 

He predicts that the next two years will be dire for small cannabis businesses unless the state reforms the legal framework ASAP. “The clock is ticking,” Taylor says. “I'm not saying that to over exaggerate. It absolutely is.”

Northern California could face dire wildfire danger in 2022. How high is the risk?
(Sacramento Bee) Michael McGough, April 3

Drought is one of the big concerns, but it’s not the only factor in the state’s extraordinary wildfire risk. “The vulnerability of our forests is really catastrophic,” said Scott Stephens, a wildfire science professor and head of the Stephens Lab at UC Berkeley....

...The Biden administration earlier this year unveiled a wildfire prevention plan that includes not only planned burns and thinning, but seeks to have some of the most at-risk communities build protective boundaries. It’s a vast, 10-year plan.

Lenya Quinn-Davidson, a fire advisor for the University of California Cooperative Extension whose input is included in the plan, said the acre targets in state and federal plans are “almost arbitrary.” “The acres will come if we put all the right pieces in place,” Quinn-Davidson said in an interview.

What are the PRLR-SLICK cattle? 
(Successful Farming) Madelyn Ostendorf, March 26

…PRLR-SLICK beef cattle have been gene-edited to have short hair, a trait associated with high heat tolerance and resistance. Alison Van Eenennaam, Extension specialist in animal biotechnology and genomics at the University of California, says developers can introduce a targeted double stranded break in the DNA helix to create a desired trait.

“Editing allows you to go to a targeted location in the genome, to a particular gene that you want to modify and introduce a double stranded break in the DNA,” says Van Eenennaam. “When the cell repairs, as cells do, and they see a double stranded break, you get a repair that’s not the same as what it was before. It was cut with genome editing reagents, and that can lead to an inactivation of the gene, basically knocking out that gene.”

…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

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.”


Fog, fruit and an unclear future
(Good Fruit Grower) Ross Courtney and T.J. Mullinax, Feb. 3

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.

K&J Orchard’s Cult-Favorite Asian Pears Are Getting Their Own Restaurant in Oakland
(SF Eater) Maria C. Hunt, Jan. 21

…The restaurant name finds its origins in the Latin word pometum, which means a fruit tree grove. Pomet (pronounced POM-et) is the Romanian word for orchard; it’s a tribute to her mother Kalayada Ammatya and father James Beutel who started K & J Orchards in 1982. Beutel, who died in 2016, was a noted fruit researcher, lecturer, and Cooperative Extension agent with University of California, Davis for 35 years. He was also the pioneering pomologist who introduced fragrant Asian pears and kiwifruit to California and worked on making the pear and peach tree varieties in California more hardy, according to the UC Davis website.

What is a healthy forest in California? These scientists are experimenting west of Lake Tahoe.
(CapRadio) Manola Secaira, Jan. 19

What does a healthy forest look like? 

There are dozens of ways you could find an answer, but Rob York [UC Cooperative Extension specialist] has his own simple litmus test. It starts with his own question: 

“Can you run through it?” 

…And now researchers say that managing California’s forests means a balancing act. 

“It’s really a societal question on what mix you’re able to have,” said John Battles, a professor of forest ecology at UC Berkeley who’s conducted studies in the forest. “And then that becomes, ‘How do you balance those?’”

Alfalfa suits a water-challenged future
(Hay and Forage Grower) Mike Rankin, Jan. 11

The current drought in the West has likely had no greater impact on other agricultural entities than on alfalfa, according to Dan Putnam, the longtime extension forage agronomist with the University of California in Davis.

“Drought is nothing new,” Putnam asserted while speaking at the Western Alfalfa & Forage Symposium in Reno, Nev., last November. “It’s something we’ve seen in the West for many years. But drought isn’t necessarily our biggest challenge; it’s more the variation in water supplies as we can go from drought to periods of flooding in a short period of time.” Regulatory curtailments of water supplies are also a major concern.


2021’s biggest climate and weather disasters cost the U.S. $145 billion – here’s what climate science says about them in 5 essential reads
(The Conversation) Stacy Morford, Jan. 10

… As rising global temperatures dry out vegetation, forest managers are dealing with increasing wildfire risks and costs. Fighting huge wildfires, like the Dixie and Caldor fires in California that destroyed much of Greenville and Grizzly Flats in 2021, depletes funds needed for fire prevention efforts, such as forest thinning and prescribed burns, University of California forest and fire experts Susan Kocher and Ryan Tompkins wrote.

“To manage fires in an era of climate change, where drier, hotter weather creates ideal conditions for burning, experts estimate that the area treated for fuels reduction needs to increase by at least an order of magnitude,” they said.

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.

Also participating at Symposium were university researchers and top-level members of the Brown Administration.


New study sheds light on how deer cope with wildfires
(Field & Stream) Ken Perrotte, Dec. 13

A study reported in the journal Ecology and Evolution in late October reveals insights into how blacktail deer responded following the catastrophic 2018 Mendocino Complex Fire in California. Somewhat surprisingly, the deer demonstrated a powerful loyalty to their small home ranges, returning soon after the fire and living on the scorched ground, even though high-quality, unburned habitat was available about a mile away.

The research, led by Samantha E.S. Kreling and Kaitlyn M. Gaynor, involved 18 radio-collared deer at the University of California’s 5,358-acre Hopland Research and Extension Center. The center is the principal field research facility for agriculture and natural resources in the state’s North Coast region.

California goes to war with food waste: Composting is its next climate crusade
(Los Angeles Times) James Rainey, Dec. 9

Scientists have found that this kind of reconditioning of biological matter produces far less Earth-warming methane and carbon dioxide than landfilling. The atmospheric benefit is compounded when farmers put the compost onto their fields, often to feed “cover crops” such as mustard that help sink carbon back into the Earth.

“It’s like a no-brainer,” said Kate M. Scow, a soil scientist at UC Davis, who has measured how compost helps remove greenhouse gases from the atmosphere. “You can’t build carbon in the soil unless you feed carbon in. ... It’s a way of closing the loop.”

Yana Valachovic, forest advisor for the University of California Cooperative Extension in Humboldt and Del Norte counties, agreed that “trends are going in the right direction” but warned that “current conditions aren’t necessarily a prediction of future conditions.”

“We really lucked out by getting that early season rain,” she said. “… We often get a prolonged dry period in December, January, and February, so things could reverse pretty quickly too. We’re hopeful that they go in the right direction, but just keep in mind that we can have fire activity or fire behavior during that winter dry period or if the season shortens up pretty quickly like it did last year when we didn’t get precipitation after March.”


New “climate stewards” course will begin at HREC in 2022 — registration open now
(Mendo Voice) Kate B. Maxwell, Nov. 15

Beginning in January, the University of California Hopland Research and Extension (HREC) will be launching a new “climate stewards” program, helping residents learn “how climate is changing natural and social systems, and what they can do to improve ecosystem and community resilience,” according to the announcement. The program is a combination of online and in-person classes and field trips, and will focus on “fire, water and stewardship,” with guest speakers and activities to identify methods of building community resilience. The University of California Climate Stewards course is similar to the naturalist program previously held at HREC and around the state.

…HREC’s director, John Bailey, who oversees the site and its many operations, explains that back in 1951 the site was purchased as a sheep center when there were about 10 times as many sheep as there are now in California.

“Over time, the center has evolved, along with the needs in the area, and today we do more work in wildlife ecology, diverse aspects of climate change, whether it’s soils or plants or wildlife interactions, fire ecology and fire science,” he says.


Prescribed burns are key to reducing wildfire risk, but federal agencies are lagging
(Los Angeles Times) Alex Wigglesworth, Nov. 8

...Another 5,000 acres were treated with broadcast burning, which in combination with thinning has shown to be most effective.

“That’s just depressing,” said Lenya Quinn-Davidson, fire advisor for the University of California Cooperative Extension. “That’s so little, given how much land the Forest Service manages in California. It is just a drop in the bucket.

“I think it speaks to the need for such drastic change around prescribed fire.”


Family farms struggling as California drought worsens: 'We haven't faced anything like this'
(Central Valley News Collaborative) Nadia Lopez, Nov. 5

...Water scarcity, combined with these other challenges, could lead to thousands of families losing their businesses and no longer supplying specialty fruits and vegetables to markets and businesses across the state, resulting in the “increase towards more consolidation into larger farms that are going to be less diverse,” according to Ruth Dahlquist-Willard, a small farms advisor for the University of California Cooperative Extension.

“There’s a lot at stake,” said Dahlquist-Willard, who helps connect diverse and socially-disadvantaged farmers to resources. “The viability of smaller farms might be affected and our landscape will continue to change to maybe a few more high value crops versus a bigger diversity of a lot of different kinds of crops.”

Why fire experts are hopeful
(High Country News) Kylie Mohr, Nov. 1

So, if we know what works, why isn’t it happening? “That’s the million-dollar question,” said Lenya Quinn-Davidson, a fire advisor with the University of California Cooperative Extension in Humboldt County and the director of the Northern California Prescribed Fire Council. “The holdup is so multifaceted.” Hurdles include getting vast numbers of private landowners to work together and understand what they need to do, dealing with federal and state regulatory barriers, permitting red tape, an insufficient federal workforce, a lack of funding, the risks stemming from liability and insurance policies, and a deeply ingrained fire suppression mentality.

"It is great that we received this much rain early in the season, which helped with wildfires and air quality,” wrote Helen Dahlke, associate professor in Integrated Hydrologic Sciences at the University of California at Davis, in an email. “The more these precipitation events are spread out over the rainy season the more chance the rain has to infiltrate and replenish soil moisture storage.”


Storm took a big toll on Bay Area trees. Did the drought make them more vulnerable?
(San Francisco Chronicle) Kellie Hwang, Oct. 26

Of course, big storms always claim trees as casualties.

“A powerful storm will inevitably result in some damage to trees, whether from falling branches or even uprooted trees,” Igor Lacan, urban forestry adviser for the UC Cooperative Extension, wrote in an email.

However, California’s historic drought is “certainly not helping,” he said. “A drought will have weakened some trees and even killed some,” priming them to topple in a storm.


Current approaches to wildfires risks lives and wastes money, say experts
(The Guardian) Sarah Johnson, Oct. 24

As Cop26 approaches and is expected to shine a light on the importance of protecting ecosystems and building defences to avoid loss of homes and lives, experts say a lack of foresight and funding worldwide means harmful wildfires will continue to rage, putting communities and firefighters in danger.

Lenya Quinn-Davidson, a fire adviser at the University of California, said: “We’re seeing our historical approach to fighting fires is no longer working. We saw this summer in California that going out, attacking fires and putting them out was totally ineffective.”


Thirty years after the Tunnel Fire: In many ways, Oakland Hills are more vulnerable today
(SFbay.ca) Nik Wojcik, Ian Sumner, Oct. 21

…Matteo Garbelotto, University of California, Berkeley professor and one of the state’s leading tree pathologists, was contacted this year by the U.S Forest Service and the San Francisco Public Utility Commission and asked to conduct an investigation. He was basically told: 

“You got to stop everything you’re doing and you’ve got to work on this.” 

The agencies were urgently concerned with a surge of tree death in the Bay Area. While eucalyptus trees were being impacted, Garbelotto found a “much greater mortality” in acacias. 

What he observed across the state were two already identified native, or naturalized, fungi that grew rampant as a result of the abnormally wet 2017 winter. The “opportunistic organisms” have infected non-native, invasive acacias, which are already stressed by drought and high propagation rates..He believes the infection may be spreading to eucalyptus as well. 

But Garbelotto discovered a third fungus unique to the Leona Heights neighborhood in the Oakland Hills, which compounds morality in that area. 


New Farm Advisor shares plans with BOS

What does California’s drought mean for the rest of the country
(Marketplace) Samantha Fields, Oct. 20

… So far, Munch said, American consumers haven’t really been feeling the effects of the drought in California. The longer the drought goes on, the more likely that is to change, according to Tapan Pathak, an agricultural climate scientist at the University of California, Merced.

“We could potentially see reduction in the availability of the fruits and vegetables that’s consumed by people every day,” Pathak said — things like lettuce, lemons, avocados and all sorts of nuts.

“At the same time, we could potentially see higher food prices,” Pathak added.


UC Berkeley students clean eucalyptus debris to prepare for fire season
(Daily Cal) Lance Roberts, Oct. 20

…Eucalyptus trees are quite a problem for California — according to campus professor of environmental science, policy and management Matteo Garbelotto, eucalyptus oils are easily ignited. When they are set ablaze, Garbelotto says that the gases formed from the oil cause something similar to an “explosive combustion.”

What’s worse, a pathogen is making eucalyptus trees even more flammable. The pathogen, called Pseudosydowia eucalypti, is a major reason why so many eucalyptus trees are drying out and posing a threat, Garbelotto said.

“In some of these strands (of eucalyptus trees), a hundred percent of the trees are infected by this fungus,” Garbelotto said. “Basically it’s like firewood ready to be burned.”

…“If you’re a new grower you kind of want to know what it’s going to cost to grow the oranges and it really does do a pretty good job of that. We really look into the cost in some detail. It’s not only to produce oranges, but also to plant them. It covers a whole range,” said co-author Craig Kallsen, UC Cooperative Extension farm advisor in Kern County. “For new growers, it gives them an idea of what they need to do. It’s almost like a production manual because it tells them when to do it as well because the costs are associated with doing various things at various times during the year.”

Wildfire Torched the Sierra All Summer, Evading Containment. Here’s How Tahoe Protected Itself
(KQED) Ezra David Romero, Danielle Venton, Emily Zentner, and Raquel Maria Dillon, Oct. 5

Susie Kocher watched with increasing dread as the Caldor Fire roared across the western slope of the Sierra Nevada, churning toward her home near the base of Echo Summit.

From high along the granite ridge nearby, the view of Lake Tahoe is normally pristine — a cerulean ocean in the sky, dotted with boats and casinos lining the pine forest along the South Shore. But for two weeks at the end of August, smoke as brown as car exhaust clouded the basin’s air.

As Kocher well knows, having worked tirelessly for more than a decade to prepare this community for a wildfire as a UC Cooperative Extension forestry adviser, under almost every tree near South Lake Tahoe is a house.


Water is scarce in California. But farmers have found ways to store it underground
(NPR) Dan Charles, Oct. 5

…Flooding more land probably will flush those agricultural pollutants into aquifers, says Helen Dahlke, a hydrologist at the University of California, Davis. "We often see a spike in nitrate, for example, at the groundwater table below a recharge site," she says.

In the long run, though, she thinks it will be good for water quality. "Most of the water that we use for recharge is very clean, because it comes from rainfall or snowmelt from the Sierra Nevada Mountains," she says. "Eventually there will be a pulse of clean water also coming into the aquifer, which can dilute many of the pollutants that have moved into the groundwater over the last couple of decades."

Facing Drought, Wildfires, Scorching Heat, Bay Area Wineries Are Changing How They Grow Grapes
(KQED) Ezra David Romero, Sept. 30

…A study released this summer by Kaan Kurtural, a UC Davis viticulture specialist, found that California's wine industry is "not at a tipping point" because of climate change or its effects — although heat waves and fires can have an immediate impact on winemaking.

"I tell the growers your grapevines are not going to die," he said. "They might not be economical to grow for one or two years, but they always come back. There are very resilient plants. So we're able to adapt."

He also found that the climate has warmed steadily in California since the 1980s. But he says this has not been bad for the wine industry in the Golden State  — a warmer climate helped establish the state as a premier wine growing region globally.

"As it became warmer we started harvesting sweeter grapes, and with sweeter grapes, the wine ratings have steadily increased," he said.


How to protect your home from wildfires
(Washington Post) Aaron Steckelberg and Tik Root, Sept. 30

…Embers can also find their way into your home through vents, such as those in the attic or in the roof’s overhang. Yana Valachovic, a forest adviser affiliated with the University of California, notes there have been technological developments in this area. For instance, there are vents designed to swell when exposed to heat as a way of sealing off a house.

…Outside your home, the goal is to remove as much potential fuel for the wildfire as possible. The first five feet are particularly crucial, experts say. “By doing that first five feet, you basically interrupt the pathway of the flames to the house,” said Valachovic.

Scientists Are Racing To Save Sequoias
(NPR Short Wave) Maddie Sofia, Sept 28

… Without fires, the Forest got a lot denser. The trees are closer together. The undergrowth has built up, and that's what's helping fuel these really extreme fires, the kind that sequoias, it turns out, just can't survive. That's what was striking to Scott Stephens. He's a UC Berkeley fire scientist who was out with the field crew that day. They were there to catalog the mortality but also to study the forest density around the sequoias.

SCOTT STEPHENS: You know, they've been here 1,500 years. You know, and each tree maybe survived 60, 70, 80 fires. You know, that's incredible. And then one fire comes in 2020. And all of a sudden, they're gone. That is a travesty.

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.”

Now an industry standard with different versions available to growers, the so-called pressure bomb device essentially monitors the moisture levels in a tree’s miniature plumbing system, said Ken Shackel, a professor of plant sciences at the university.

…Pat J. Brown, a UC Davis associate professor who is a nut crop breeder, selects varieties for low-water requirements and indifference to saline soils. At the Torture Orchard, Brown and his colleagues fed pistachio trees increasing amounts of salty water. Scientists were delighted that their work did not kill a single tree, suggesting that growers someday may be able to use briny water, not just scarce fresh water, to irrigate  orchards.

…The gnarled trees produce a small, blonde nut, the favorite of Tom Gradziel, a Davis professor of plant science and an almond breeder. Gradziel walks through the orchards the way farmers do, reaching out to pluck fruits and nuts, checking them and absently snacking as he goes.



Sacramento’s wine scene touches Lodi, Clarksburg & Amador CA
(Sacramento Bee) Benjy Egel, Sept 12

… But as with grapes grown around Clarksburg, Plymouth and the Capay Valley, some stick around and end up producing exceptional small-batch wines right in Sacramento’s backyard. Area micro-producers keep their region’s grapes local and turn out world-class wine, UC Davis viticulture and enology department chair David Block said.

“Some of these places are making wine that rivals Napa and Sonoma and places in Northern California that are maybe more known for their wine,” Block said. “Are they the same as wines in Napa? They aren’t the same because they’re made in a different place. Are they as good? I think some of them are probably as good, if not better.”

CA’s Dixie Fire puts Ag Pass program to test
(Western Livestock Journal) Charles Wallace, Sept. 3

…According to the California Department of Forestry and Fire Protection (CAL FIRE), as of Aug. 4, the Dixie Fire was 274,139 acres and 35 percent contained. Tracy Kay Schohr, University of California (UC) Cooperative Extension (UCCE) livestock and natural resources adviser for Butte, Plymouth and Sierra counties, told WLJ some livestock producers are in the mandatory evacuation area, particularly in the burn area of Greenville/Indian Valley of Plumas County.

“The concept of it is completely working,” Schohr said. “Before the fire became a major incident and was being managed by just the Butte County CAL FIRE, I got a phone call from a CAL FIRE captain who asked me, ‘Hey, I know there are cattle in this area, can you figure out whose cattle they were in Plumas County? The fire is headed that way. They probably have two days to get their cattle out.’ And so the relationships that we had built, working with CAL FIRE to develop the Ag Pass program really facilitated that communication back to me.”

… Dan Macon, UCCE Livestock and natural resources adviser, told WLJ the livestock access program for Placer/Nevada/Yuba counties was developed based on examples from other counties in the state.

…“I do think the Dixie and the way that it’s burned and its magnitude did impact the early response to the Caldor,” said Scott Stephens, a professor of wildland fire science at the University of California, Berkeley. “It really drew resources down so much that the Caldor got very few for the first couple days.”

…“They’re trying to predict winds at a mountain pass. That is the most complex topography we have,” [John] Battles [a UC Berkeley professor of forest ecology] said. “That’s why you have this feeling like they didn’t know what they’re doing.”

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."

Those soil test results are key inputs for one of his newest tools: CropManage, which is operated by the University of California Cooperative Extension and uses data from NASA and other sources to create customized irrigation and fertilizer recommendations. In addition to satellite measurements of crop development, it gauges local weather, soil characteristics, and irrigation system efficiency.


No Prop 12 delay as state's pork prices set to rise
(Farm Press) Tim Hearden, Aug. 30

…The hearing came as University of California, Davis economists estimated on Aug. 27 that California pork consumers will lose $320 million per year (roughly $8 per person) from the market impacts of Prop. 12. California consumers will pay about 8% more for pork regulated under Prop. 12 and will consume around 6% less of that pork per year, according to the study.

“The roughly 9% of North American sows affected will each get about 20% more housing space," noted coauthor Richard Sexton, a UC Davis professor of agricultural and resource economics. "But, the additional space will be for those sows that already have more space, not those confined in small individual stalls.”

Landscaping with wildfires in mind can help homes
(Western Farm Press) Pamela Kan-Rice, Aug. 26

What can Californians do to improve the chances that their homes will survive a wildfire? Simple actions taken around the home can substantially improve the odds that a home will survive wildfire, according to UC Cooperative Extension advisors. 

During wildfire, structures are threatened not only by the flaming front of the fire, but also by flaming embers that are lofted ahead of the fire front and land on fuels such as vegetation or mulch next to the house, igniting new fires. Traditional defensible space tactics are designed to mitigate threats from the flaming front of the fire but do little to address vulnerabilities to embers on or beside a structure.

The auction grossed about $519,000—and led to more support for a Dixie Fire relief fund. Neer said Five Marys Farms out of Fort Jones in Siskiyou County came to the auction with the intention of supporting Indian Valley students who lost homes and animals to the fire. Five Marys resold its auction purchases and donated the funds to Dixie Fire relief efforts.

Other donations were made to the Clayton Floyd Neer 4-H Steer, Swine, Sheep and Goat Loan fund, Neer said.

By nearly every metric, the wildfires in the Western United States are worsening. They are growing larger, spreading faster and reaching higher, scaling mountain elevations that previously were too wet and cool to have supported fires this fierce.

They are also getting more intense, killing a greater number of trees and eliminating entire patches of forest.

“Ten years ago, we weren’t really seeing fires move like that,” said Lenya Quinn-Davidson, a fire adviser for the University of California Cooperative Extension, referring to 2021’s Bootleg Fire, which began July 6 and at one point consumed more than fifty thousand acres in a single day.

Exploding California Wildfires Rekindle Debate Over Whether to Snuff Out Blazes in Wilderness Areas or Let Them Burn – Inside Climate News
(US News Mail) Aug. 11

Before Euro-American settlement, an estimated 4.5 million acres or more would burn in California every year. Last year’s historic fire season charred a little more than 4 million California acres, and nearly 10 million acres throughout the West, the second most acreage burned since 1960. 

“This was a fire adapted ecosystem. The higher up you went in the mountains, the more there was an influence from lightning,” said Susie Kocher, forestry and natural resources advisor for the University of California Cooperative Extension. “But lower down and on the coast, it was mostly Native burning.”

‘Where do I go?’: Thousands flee as Dixie Fire morphs into third-largest blaze in California’s history
(Washington Post) Aaron Williams, Marisa Lati, and Maria Luisa Paul, Aug. 8

The Dixie Fire covers more than 432,000 acres in Butte and Plumas counties, rapidly expanding from about 362,000 acres Thursday evening and fueled by hot, arid and windy conditions. The wildfire was 35 percent contained by Friday, pushing toward firefighters’ control lines. Fire officials expressed hope Friday that higher humidity would help them counter the blaze.

“It’s kind of the perfect storm,” Yana Valachovic, forest adviser and county director at the University of California Cooperative Extension, said of the Dixie Fire. “We saw all this. The potential was high this year for these kinds of conditions, and once you get an ignition, especially in areas that are a little bit difficult to access and with new communities all around there, it stresses the system.”


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.


Dixie Fire explodes to largest blaze in U.S., third largest in California history
(NBC News) Wilson Wong, Aug. 6

…Scott Stephens, a professor of wildfire science at the University of California-Berkeley, said the explosion of wildfires in the past decade has been fueled by the culmination of drought conditions, hotter temperatures and flammable forest debris, like downed trees. These conditions, he said, are exacerbated by climate change.


CalFresh Can Be Used at California Farmers Markets, But Many Recipients Unaware, UC ANR Reports

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.

…The Crop Report Plus is not just a valuable tool for Imperial County government officials, it’s also necessary information for the local ag researchers, according to Dr. Oli Bachie, agronomy adviser and county director of the University of California Agriculture and Natural Resources’ Imperial County Cooperative Extension.

“The Crop Report and the Crop Report Plus is very, very important. It is one of the main resources that we at the Imperial County Cooperative Extension use for looking at production,” Bachie said after the afternoon presentation. “We can’t work without it. It’s very valuable and heavily used at the cooperative.”


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.”

Marin Master Gardeners’ drought-tolerant demonstration gardens offer inspiration
(Giving Marin Community Partnership) Jane Scurich, July 30 

As the reality of our water crisis settles in, and we begin to think seriously about saving every precious drop, it’s time to plan for some drought-tolerant replacements for our lawns as well as thirsty annuals and perennials. Garden books and visits to local nurseries provide lots of ideas, but there is nothing like observing a drought-tolerant specimen thriving in an actual garden. There may be no place better to begin your search than the UC Marin Master Gardeners’ demonstration gardens.


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

Broad data patterns on climate change, frequency of fires or dry vegetation do not tell the whole story on California’s wildfire problems, according to Max Moritz, statewide wildfire specialist at the UC Cooperative Extension. People and the changes they’ve made to the landscape matter, too.

“That’s because we have done a lot of things to our landscape at finer scales,” Moritz said. “Look at the power line infrastructure. We’ve got road networks, we’ve got housing developments at different densities across the landscape.”


More ‘good fires’ could help California control future catastrophes
(US News Mail) July 28

In order to get the state back on track with its historical fire patterns, researchers suggest that about one million acres should be burned every year. The reality has been more than an order of magnitude away, despite persuasive evidence that prescribed burns are effective.

“We are just so out of touch with fire now,” says Lenya Quinn-Davidson, a fire expert at the University of California’s Humboldt extension. “So much of our forests have this huge backlog, and we’re going to need to use prescribed fire to protect resources we care about—communities, places we love—and set larger landscapes up to thrive again.”

(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.”

‘Liquidation of cows.’ How the drought creates chaos on California ranches, dairy farms
(The Fresno Bee) Dale Kasler, July 29

So far the drought isn’t raising consumer prices, but that’s likely to change. In the meantime, ranchers and dairy producers are getting squeezed financially by higher costs — and are left with dwindling options.

“You’re going to have to cull your cattle,” said Tracy Schohr, a rancher and livestock advisor for UC Cooperative Extension in Quincy. “You’re going to have to make decisions about which cattle to sell.” Her ranch sold 15 animals earlier this year.

Humans are the cause of most wildfires. Climate change will make that worse
(The Hill) Zack Budryk, July 24

…“While it hasn’t gotten as much study, it would also appear that there’s an increase in the number of red-flag days, or the number of days affected by high-wind incidents,” according to Sabrina Drill, the natural resources adviser for University of California Cooperative Extension in Los Angeles and Ventura counties.

These conditions can be particularly dangerous in Southern California, where the majority of fires are driven by drifting embers, she added. In addition to spreading individual fires, she noted, high winds can increase the rate at which moisture in vegetation evaporates. The couple whose gender reveal ignited the San Bernardino County fire were unable to extinguish it with water bottles due to the high winds present at the site.

“That’s also why during big wind events we have a lot of these power companies actually shutting power off,” said Max Moritz, a cooperative extension wildfire specialist at the Bren School, UC Santa Barbara.

Forest fires intensify. Here’s why and what can be done
(Newsbeezer) July 21

“We have good science that shows homes retrofitted or built this way are more likely to survive forest fires,” said Susie Kocher, forest consultant at the University of California Cooperative Extension.

Landscape changes can also make a difference. Fire experts think in terms of the 0-5 zone, which refers to the five feet of circumference around a house. This zone should be kept free of debris, firewood, plants, or mulch. “It looks nice to put a bush under our window, and that’s exactly the wrong thing to do,” says Ms. Kocher.

The number of controlled burns is rising in California. Is it enough?
(SF Chronicle) Yoohyun Jung, July 17

…The public’s perception of prescribed fires has shifted in the past five to 10 years, said Lenya Quinn-Davidson, fire adviser with the University of California’s Cooperative Extension and director of the Northern California Prescribed Fire Council. There’s an increased acceptance of their value as a tool to reduce fire risk.

“People in general are tired of scary fire season after scary fire season,” she said. The public is desperate for a solution and rethinking what’s working versus not, and community members — not just fire agencies — are increasingly getting involved in prescribed fire efforts by joining and forming associations, of which there are 13 now in California, she said.


Wildfires Are Intensifying. Here’s Why, and What Can Be Done
(New York Times) Winston Choi-Schagrin, July 16

By nearly every metric, the wildfires in the Western United States are worsening. They are growing larger, spreading faster and reaching higher, scaling mountain elevations that previously were too wet and cool to have supported fires this fierce.

“We have good science that shows that homes that have been retrofitted or built in this way are more likely to survive wildfires,” said Susie Kocher, a forestry adviser with the University of California Cooperative Extension.

UC Berkeley study finds marijuana farms require less water than previously assumed
(The Daily Californian) Kavya Gupta, July 14

Researchers looked into farms in Northern California, including those in Humboldt, Trinity, Mendocino and Sonoma counties. Their findings found that earlier assumptions about marijuana production and water use had been misinformed by incomplete data. Earlier studies did not take into account differences in growing conditions, temporal variation and water storage.

According to Van Butsic, campus assistant cooperative extension specialist and one of the study’s researchers, legal marijuana production is generally sustainable, given that stored water is used.

More catastrophic fires in California - can Australia's prescribed burning help?
(Australia Broadcasting) Linda Mottram, July 12

Another catastrophic fire season has begun in the western United States. Multiple, massive blazes are raging in several states, some defying fire fighting efforts, as temperatures soar above 50 celcius in places, in tinder dry, prolonged drought conditions. Lenya Quinn-Davidson, Northern California Area Fire Advisor with the University of California Cooperative Extension, says climate change is driving fire seasons that some estimate are about 70 days longer than in the past. But she says is 100 years of keeping fire out of fire-adapted and fire-dependent ecosystems, allowing fuel buildup, which feeds worsening seasons. She says active management of the system, including prescribed burning on the Australian model, and better building and planning are vital tools to ameliorate the impact of wildfires.

Connecting Ranchers with Land Stewards Could Be Key to Less Disastrous Wildfires
(Civil Eats) Anna Guth, July 8

…“I finally said, ‘Enough!’ [We’ve had] four catastrophic fires and we’re not doing enough with the livestock owners in the areas where vegetation has grown back to continually manage it,” said Stephanie Larson, who directs the University of California Cooperative Extension in Sonoma County and served as a consultant to the Fitch Mountain project.

… Sheila Barry, a U.C. Extension livestock and natural resource advisor and a contributor to the cattle study, highlighted that as long as land managers use practices, such as rotational or “managed” grazing—which involves regularly rotating the animals between separate pastures or “paddocks”—there can be myriad additional ecological benefits besides addressing wildfire. Barry’s research has shown positive impacts for special status species, such as the California Condor. She also found evidence that the managed grazing can help control non-native plants, providing habitat for pollinators, and sequestering carbon.

…Scott Stephens, a forestry professor at UC Berkeley is seeing evidence of that firsthand in the Plumas County town of Quincy, where he’s teaching a summer field course for undergraduates.

He said after several weeks of temperatures above 90 degrees, plants there are “already showing signs that look like August: leaves starting to shrivel, shutting shut down because moisture is being depleted by the heat.”

“The hot temperatures plus the combination of two years of below average precipitation this year is really worrisome because that lower moisture is going to make fire behavior more extreme, spread rates more extreme,” he said.


Study Shows Growing Cannabis Uses Less Water than Previously Thought

… 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."


In Russian River’s fabled vineyards, the harvest of a drought
(Mercury News) Lisa Krieger, June 21

“Whatever water we have on the ground is all we’re going to get,” said Mendocino County supervisor and [UC ANR emeritus] plant scientist Glenn McGourty, whose district spans the rural upper reaches of the river’s watershed, where the dance of cool nights and hot days, combined with alluvial soil, produces unique growing conditions.

“We hope and pray that we can make it to harvest without our fruit becoming raisins and the leaves falling off the vines,” he said.

Due to the exclusive geographic region of almond crops, Rijal has the opportunity to study unique agricultural systems and the pests associated with them. Navel orangeworm (Amyelois transitella) is recognized as the most economically important insect pest of all major nut crops in California (which include almonds pistachios, and walnuts), but until now, little has been published about the 60 other species of insect pests that infest almond orchards.


Industry Survey Looks at The Impact of Wildfire on Grazing Livestock
(Ag Net West) Brian German, June 17

…“What we wanted to do with this survey is find out from producers what they observed,” said Gabriele Maier, Cooperative Extension Assistant Specialist at UC Davis. “Did they see an increase in respiratory disease? Was there any impact possibly on reproduction or on other production parameters? On weight gain? On milk production for dairy animals? So, we just want to see if people noticed any impact on the health or production of their livestock.”

What is causing meat prices to rise?
(KRON4) Noelle Bellow, June 16

…“Beef prices have bene relatively cheap for a while, and now they’re not at all.”

Professor of Agricultural Economics at UC Davis Daniel Sumner says the seasonal increases will always come and go, but this year most of the increase you’re paying for has to do with the cost and demand for corn and soybeans.

“Its supply and demand fundamentals in a worldwide basis.”

“Underlying is the price of corn and soybeans. What does a steer eat? Corn and soybeans. What does a pig eat? Corn and soybeans. And those crops have gotten more expensive in part because of demand from China. They don’t produce a lot of that in China, they’re willing to pay for it so there they go. So that demand you and I see is when we go to the Costco or other super market.”

Professor Sumner also points to slower production lines at meatpacking plants following the pandemic, but he’s confident prices will moderate soon.

“Within a month or two, we’ll see some moderation “I’m thinking.”


Oregon governor signs bill to explore liability changes for prescribed fire
(Capital Press) Sierra Dawn McClain, June 14

Prescribed fire, also known as “planned,” “Rx” or “controlled” fire, is a fire set intentionally to limit hazardous fuels on the landscape — for example, by burning brush under trees in the spring to prevent a larger wildfire in the summer or fall.


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

Wintertime flooding in permeable areas is one way groundwater can be recharged as it is used during the dry season. Getting access to water, developing infrastructure and flooding large farms will allow water to seep back into aquifers. Small-scale farmers can also be involved, said Ruth Dahlquist-Willard, the UC Cooperative Extension advisor to small-scale farmers in Fresno and Tulare counties.


Extension services are the best free cooking resource

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.

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

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.”

Guardian dogs bond with livestock, deter predators
(AgAlert) Bob Johnson, April 28

… "They mostly work as a deterrent," said Carolyn Whitesell, University of California Cooperative Extension human-wildlife interactions advisor. "They will mark the pasture, to let the predators know."

… Sheep rancher Dan Macon, who also works as the UC Cooperative Extension livestock advisor in Placer, Nevada, Sutter and Yuba counties, put his Pyrenees-mix guardians Elko and Dillon with his sheep when they were 12 weeks old.

… "You can spend from $250 to $1,500 for a collar, but I use build-yourself collars to track the dogs' activity that cost me from $60 to $100 to make," Macon said.


Local rice fields being prepared, planted for season
(Appeal Democrat) Lynzie Lowe, April 28

…Whitney Brim-DeForest, University of California Cooperative Extension rice and wild rice advisor and county director, said growers have been able to get into the fields a little earlier than usual to conduct tillage operations and apply fertilizers due to the record dry winter the region has experienced this year.

“Average rice planting date is usually May 15, with most fields planted in the month of May,” said Brim-DeForest. “Some fields this year have already been planted, so I would guess that the average planting date for 2021 will be a little earlier than normal.”

But promising solutions exist.


California ‘burn bosses’ set controlled forest fires. Should they be safe from lawsuits?
(Sac Bee) Ryan Sabalow and Dale Kasler, April 22

…Generally, burn bosses working for Cal Fire and the U.S. Forest Service are protected if something goes awry. But private bosses, working primarily on private land, face the prospect of litigation if a fire gets out of control, said Lenya Quinn-Davidson, who heads the Northern California Prescribed Fire Council.

…Quinn-Davidson said the problem isn’t just liability, “it’s also perceived liability — people are scared to get involved in prescribed fire. Escape rates are very limited but for the private practitioner who wants to get involved in this work, it’s a barrier.”

(Farm Press) Todd Fitchette, April 22

California farmers aren't the only ones suffering with zero water allocations this season. The research efforts they rely upon from Extension programs will also be hurt as two University of California research stations have been told not to expect surface water deliveries and others may suffer similar water woes this year.

… "We can't do anything with zero water," said Rob Wilson, director of the Intermountain REC.


California's droughts sometimes make better wine - but they're bad for the industry overall. Here's why
(San Francisco Chronicle) Esther Mobley, April 21

…“Our water footprint is awfully low compared to other crops, and grapes are more drought resistant,” says [Kaan] Kurtural [an associate specialist in cooperative extension in viticulture with UC Davis]. Whereas almonds need about 4 acre feet of water to grow in California, he says, grapes demand only about 1 to 1.5 acre feet.

We Need to Talk About the Enviornmental Impact of Marijuana
(InHabitat) Grae Gleason, April 20 

To further illustrate the importance of decriminalization, JSTOR Daily enlisted Van Butsic, co-director of the Cannabis Research Center at the University of California Berkeley. As Butsic explains, “There are lots of technologies that capture VOCs before they enter the atmosphere that are required in other industries like gas stations.” But, “before [emissions] standards can be set for cannabis, we need recognition of the issue and long-term data to develop regulatory statutes—and we’re a long way from that because federal prohibition has hindered research and we don’t have the science yet.”


The Los Angeles River’s overlooked anglers
(High Country News) Miles Griffis, April 20

…“Most tend to think the quality of the water in the Los Angeles River is poor, but it’s fairly clean water,” says Sabrina Drill, natural resources advisor for the University of California Cooperative Extension. While toxicity varies by species and location on the river, a 2019 LA River report found that a person can safely consume 8 ounces of common carp, bluegill, and green sunfish, up to three times per week. Still, Drill did not recommend this, since most of the studies contained small samples.


'Dry fallowing' ground may aid in weedy rice control
(Farm Press) Todd Fitchette, April 20

…Managed fallowing can help with some varieties of weedy rice, according to Whitney Brim-DeForest, Extension rice advisor with the University of California. This is a practice that still uses irrigation water but does so on a more limited basis than if fields were planted to common rice varieties. During the last multi-year drought period a few years ago she said some growers left fields unplanted for more than one season to get a handle on weedy rice populations. That seemed to work for them.


Is California suffering a decades-long megadrought?
(LA Times) Alex Wigglesworth, April 18

… Annual droughts are also nothing new. “You will have these dry years and then in between you will get these really, really wet years,” said Safeeq Khan, assistant cooperative extension specialist of water and watershed sciences at the University of California Division of Agriculture and Natural Resources. “They can be what we describe as drought busters.”

… “From a water supply aspect, that ended the drought,” said Doug Parker, director of the California Institute for Water Resources at UC Agriculture and Natural Resources. “From an ecosystem aspect, I don’t think our forests and our natural lands that rely on rainfall ever fully recovered from that drought, and now we’re into the next one.”

…Groundwater supplies also take years to rebound, said Hoori Ajami, assistant professor of groundwater hydrology at UC Riverside, who is part of a team of researchers that analyzed data from wells impacted by climate for a paper currently in peer review.

“Once your precipitation has recovered, that doesn’t mean your stream flow is recovered or your groundwater is recovered,” she said. “Our estimate is it could take for groundwater between three to 10 years on average to recover.”


Drought adds pressure on Central Valley farmers as other factors cause food prices to rise
(ABC 10) Luke Cleary, April 16

…Snowpack statewide is only at 59% of its April 1 average, based on electronic measurements according to the California Department of Water Resources. Farmers in the Central Valley producing water-intensive crops such as almonds and tomatoes are already facing some difficult choices. 

"It's really serious, particularly in the Central Valley," said UC-Davis Agricultural Economist Daniel Sumner. 

"The cost of water, the scarcity of water adds into all the costs of food throughout the system," Sumner said. 


Why Wall Street investors’ trading California water futures is nothing to fear – and unlikely to work anyway
(The Conversation Ellen Bruno) Heidi Schweizer, April 15

… As the economics of water resources, we believe there are many benefits of a well-functioning water futures market, especially as climate change&nbsp makes the amount available for use increasingly hard to predict. The market’s main purpose, after all, is to provide protection for California water users – such as farmers and cities – against fluctuations in prices.

While there are real risks, we think they’re misunderstood and overblown. And anyway, very few are actually trading water futures.

…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.”
