Coronavirus's next victim: Big Meat
(Grist) Nathanael Johnson, April 30
“It's going to cause price spikes somewhere downstream,” said Rich Sexton, an agricultural economist at the University of California, Davis. But the average shopper might only notice empty shelves rather than higher prices, because “big grocery chains don't like to jack up prices, especially in times like this.”
…“There is going to be even more of a rush to automate farmwork and slaughterhouses,” Sexton said.
As meat plants idle, California has no shortage of fish, dairy
(NBC News) Dennis Romero, April 29
…California produces about 20 percent of the nation's milk and has a large poultry processor in Foster Farms, but is otherwise dependent on the Midwest for pork and much of its beef, according to Daniel Sumner, director of the University of California's Agricultural Issues Center.
The state slaughters dairy cows for hamburger and raises calves for beef. But the 1-year-old livestock is sent to the Midwest for corn and soy feeding before being processed for beef there, he said. "We've never produced any hogs to speak of," Sumner added.
California producers fill nearly half the state's chicken and egg demand, he said.
1-In-4 San Diegans Unemployed From Pandemic, North County Wants Businesses To Reopen, San Diego Sees Drop In Homelessness, And Online Learning Nightmare For Vets

An estimated 25% of San Diegans are out of work because of the pandemic, according to a new SANDAG report. Plus, a handful of North County mayors want businesses in their towns to reopen sooner rather than later. Also, homelessness in San Diego is seeing a decline, according to the latest homeless count. Also, it's not just young students who are having a hard time with distance learning, veteran students are also dealing with the challenges of virtual classrooms. ...

Virus-related food shortages will be temporary in U.S., experts say
(Farm Press) Tim Hearden, April 29
…“Every economist agrees that the massive hit to the world economy and trade will likely cause millions of very poor people to be out of work and with no income,” said agricultural economist Daniel Sumner, director of the University of California's Agricultural Issues Center. “This is a consequence of the disease, but also of the policy of shutting down the economy.
“In poor countries, when the economy is shut down, the poorest people get even more hungry and people die, especially the kids,” Sumner said in an email.
'We're in pretty good shape' | Northern California unlikely to see meat shortage
(ABC10) Lena Howland, April 29
… Despite the ad Tyson Foods released over the weekend, saying the food supply chain in America is breaking, UC Davis Professor Daniel Sumner said we could expect to see some higher prices, but he doesn't expect to see shelves being wiped out anytime soon.
"If you want to have some very specialized meat product, you may find that in short supply in your local market on the day you're shopping, if you went back the next day, it may be there, but I don't think anybody has to worry about the supply chain in America, we're in pretty good shape," Sumner said.
And he said the only way we will see a shortage is if people panic buy, just like they did with toilet paper.
"As we've learned in the past month or two, you could certainly create a shortage in the sense that consumers can altogether if we all ran out and decided to stock up every freezer space that we have with steaks and pork chops," Summer said.
Nature And The Coronavirus: As Humans Continue Lockdown, Wildlife Creeps Back In

Scientist at work: Trapping urban coyotes to see if they can be 'hazed' away from human neighborhoods
(Conversation) Niamh Quinn, April 29
After weeks of sleepless nights spent scrutinizing grainy images relayed from our remote cameras, mostly of waving grass and tumbling leaves, finally, there it is. A live coyote with a loop around its neck. On October 8, 2019, my colleagues and I caught the first member of the University of California Agriculture and Natural Resources pack, #19CU001.
Coronavirus: Should California brace for a meat shortage? Not exactly, say industry experts
(SF Chronicle) Esther Mobley, April 28
… There's not a shortage, exactly, say industry experts, though interruptions to the supply chain mean that it's taking a little longer than usual for meat to get from a farm to your grocery store shelf.
“We will have a short period where we have fewer packages of meat in the case,” said Daniel A. Sumner, director of the University of California Agricultural Issues Center. It will be an inconvenience, he said: “Let's say you like thin-cut pork chops, I like thick-cut pork chops. Well, one of us will be disappointed if we shop late in the day.”
Carbon Sequestration in Vineyards
(AgInfo) Tim Hammerich, April 27
...However, Extension Specialist Kaan Kurtural and his team at the Oakville Experiment Station are currently evaluating the impact cover crops can have on carbon sequestration in vineyards.
Kurtural…”Growers came to us. A couple of the questions they had was how can we sequester the carbon and how can we mitigate the amount of greenhouse gases we emit from the vineyards? So that was some background work done on it. Cover crops do sequester carbon and will store it in the soil. But as you till them, if you till the row middles, all this stuff is release back into the atmosphere. So we worked with a couple of private companies and we were able to get this new type of cover crop using a perennial system. Meaning that it doesn't have to be tilled or mowed, it just goes dormant. So we're comparing now till versus no-till systems using perennial and annual cover crops. So that's how that began.”
Covid-19 has forced large-scale farms that supply institutions to dump produce they can't sell. Why can't it just feed hungry people ? We've got answers.
(Counter) Lela Nargi, April 27
… To get a clearer understanding of where institutional food comes from, why kinks at the center of the supply chain make rerouting a challenge, and what's being done to change that, I talked to a variety of agriculture experts.
…Dr. Gail Feenstra, deputy director, Sustainable Agriculture Research and Education Program, University of California Davis: Our food system generally is built for global distribution. Now that's suddenly cracked, people are going back to more local food systems, where [important middle-tier components] like storage facilities [for meat and grain] aren't available.
…Feenstra: In California, some new food hubs are starting up to make the connection between small- and mid-scale famers with excess, and consumers who use CalFresh/SNAP. There's also work being done to figure out how to change CSAs to direct delivery or drop-off. Who is making these connections are co-op extension service agents, in every county in the U.S. They can share resources and research, and have access to grant monies. One agent told me she worked with county board supervisors to keep farmers' markets open, then with market managers to reorganize to keep the markets safe.
COVID-19 outbreak causing possible meat shortage across US
(KRON4) Dan Thorn, April 26
…“That doesn't seem to be on the horizon yet… but we have had some disruptions,” Daniel Summer said.
Those disruptions, says Daniel Sumner — a U.C. Davis agricultural economist — will not create a shortage of meat.
Even after the country's largest meat producers including Tyson, along Smithfield and JBS have recently shuttered processing plants.
“You and I may see our favorite supermarket low on something but there will be plenty of meat –beef, pork and chicken that we all like there will be plenty of meat in the supermarkets,” Summer said.
Marin farm sector struggles as virus cripples food services
(Marin IJ) Richard Halstead, April 26
… Randi Black, a University of California Cooperative Extension dairy adviser for Marin County, said, “We're kind of lucky where we are. We haven't been impacted quite as much as some of the eastern U.S. dairies have been. That's where we're seeing a lot of milk dumping.”
Black said that is because processors who buy Marin dairy farmers' milk sell most of their milk to grocery stores, while processors in the east rely more heavily on the food-services industry, which includes restaurants, hotels and airlines.
Want to save your citrus trees? Start a full-fledged insect war
(Los Angeles Times) Jeanette Marantos, April 25
…In citrus-loving California, some 60% of homes already have one or more citrus trees in their yard, said UC Riverside entomologist Elizabeth Grafton-Cardwell, director of the Lindcove Research and Extension Center in Exeter. (That's a statewide average, with fewer in Northern California and more in Southern California, she said.)
…But Mark Hoddle, a biological control specialist at UC Riverside, sees things differently. Hoddle and his entomologist wife, Christina Hoddle, also at UC Riverside, went to Pakistan in 2010 looking for natural enemies of the Asian citrus psyllid, and there they found Tamarixia radiata, tiny parasitoid wasps that lay their eggs on the backs of psyllid toddlers (a.k.a. nymphs).
Even as new technologies revolutionize farming, not everyone has access
(Sac Biz Journal) Emily Hamann, April 24
Technology could hold the key to solving growers' issues both around labor and water.
George Zhuang, a farm adviser with the UC Cooperative Extension, works with wine grape growers in the Fresno region, where machines have largely taken over the job of growing grapes.
“Most newly established vineyards go to 100% mechanization,” Zhuang said.
Amid rising costs and limited availability, farmers struggle to find enough workers
(Sac Biz Journal) Emily Hamann, April 24
…Wine grapes are known for being especially labor intensive. Grape harvesters have been commonplace in vineyards in the San Joaquin Valley for decades, but vines still needed maintenance, including pulling leaves and trimming shoots, by hand. Now that's changing as well, said Kaan Kurtural, viticulture specialist at the UC Davis.
…“We have a lot of consolidation in our business,” Kurtural said. “Vineyards are getting larger as farmers are getting old and their kids don't want to do this anymore, so they're selling their holdings.”
A Strained Food Chain
(Health in all Matters) Michael Joyce, April 24
COVID-19 has drastically disrupted the way food is produced, distributed, and available in the U.S. and around the world. The toll of the virus on those who plant, pick, buy, sell, and, at times, go hungry, is increasing. In this episode, we explore the vulnerabilities of a complex and interconnected food system and the inevitable bright spots along the way.

Farmers face new challenges in their ongoing quest for water
(Sac Biz Journal) Emily Hamann, April 24
…“Almond trees are actually pretty resilient,” said Katherine Jarvis-Shean, a Sacramento-area orchard farm advisor with the University of California Cooperative Extension.
While the trees themselves can live through a drought year, insufficient water will reduce yields for the present season and seasons into the future, Jarvis-Shean said.
But this year growers can also rely on groundwater pumped from wells drilled into a patchwork of underground aquifers.
“One year with low precipitation is not a problem with groundwater,” Jarvis-Shean said. “The problem is if we continue to have dry winters.”
Protecting The Valley's Vulnerable Populations From COVID-19

COVID-19 is disproportionately hurting vulnerable communities like seniors, ag workers and the homeless. To learn about efforts to protect these at-risk populations, FM89's Kathleen Schock spoke with Lisa Blecker, pesticide safety education program coordinator for the UC Division of Agriculture and Natural Resources, Laura Moreno, chair of the Fresno Madera Continuum of Care, and Kristen Beall Watson, CEO of the Kern Community Foundation.
Too celebratory for a pandemic, California's farmed oysters and caviar lose their markets
(San Francisco Chronicle) Janelle Bitker, April 24
…California's aquaculture industry, which includes farmed trout, clams and mussels in addition to higher-end abalone and oysters, represents about $200 million in annual sales, according to Jackson Gross, an aquaculture specialist at UC Davis.
…“Are people willing to pay for a premium local product?,” Gross said. “They're doing that at restaurants, but they're getting the frozen stuff from the big chain stores.”
Stop stable flies from biting into profits
(Progressive Dairy) Julia Hollister, April 23
It only takes five stable flies biting on the front legs of a cow to reduce weight gains and milk yields, according to Alec Gerry, a University of California – Davis veterinary entomology specialist.
Gerry, who spoke at the 2020 Golden State Management Conference in Modesto, California, has been researching flies for over 25 years. His most recent studies are in collaboration with researchers at the Veterinary Medicine Teaching and Research Center in Tulare, California.
In The Quiet Of Sheltering In Place, Have You Encountered Wildlife Differently?
(KPCC ) Larry Mantle, April 23
As the quarantine continues, residents surrounding Griffith Park have shared that they're noticing more wildlife activity - hawk nests, deer in the hills, opossums on the roads.
According to the Los Angeles Times, some wildlife biologists are saying what's changed isn't animal behavior but our own. We finally have the time and the patience to notice the wildlife around us.
Oakland Schools Use Gardening to Help Families
(KCBS radio) Matt Biglar, April 23
Canned food... diapers... tomato plants?
As KCBS Radio's Matt Bigler reports, Oakland schools are helping families get food and supplies and also get into gardening.
The plant giveaway came out of the Contra Costa Master Gardeners spring fundraiser, which unfortunately withered and died this season.
“But with the shelter in place order, we were unable to hold our plant sale.” Dawn Kooyumjian said, they decided to donate their seedlings to nearly 50 organizations, including Oakland Unified.
“People are able to come, pick up their necessities that the school district is providing, and also take home a vegetable plant that will allow them to have a little bit of food security in their home.
The Great Potato Giveaway
(NPR) Stacey Vanek Smith, April 23
…Daniel Sumner is an agricultural economist at the University of California, Davis. He says the problem boils down to two things.
DANIEL SUMNER: How streamlined and specialized things are.
...SUMNER: The farmer will be linked directly to the restaurant customers and grow for that restaurant in San Francisco or New York City or somebody growing exactly the kind of lettuce that McDonald's needs for their hamburgers. That's been a great system.
Lockdown silver linings: For a Sacramento family, baby chickens bring meaning, solace
(Sac Bee) Diana Williams, April 22
…Imagine my delight in stumbling across a backyard chicken census online. It's overseen by Maurice Pitesky, a veterinarian and epidemiologist at the UC Davis School of Veterinary Medicine-Cooperative Extension.
Pitesky's best guess is there are about 100,000 backyard flocks in California. Sacramento probably has about 11 percent of them, making ours the third-highest backyard chicken region in the state, behind Los Angeles and San Francisco.
Volunteer program donates over 30,000 plants to community gardens in Contra Costa
(KRON4) Omar Perez, April 21
A volunteer program donates thousands of vegetable plants to local undeserved communities in the Bay Area free of charge. Over the last few weeks volunteers for The Contra Costa Master Gardeners Program donated more than 30,000 plants to local school and community gardens.
…“Because of COVID-19 they were not able to have the sale so they quickly decided they would distribute the plants for free to local communities, elderly and schools,” Bay Area Program Director Frank McPherson said.
Coyotes, falcons, deer and other wildlife are reclaiming L.A. territory as humans stay at home
(LA Times) Louis Sahagun, April 21
Similarly, research scientist Niamh Quinn, who serves as human-wildlife interactions advisor for UC Cooperative Extension, said none of the five collared coyotes she is studying in the cities of Hacienda Heights, Roland Heights, La Verne and Chino Hills “have changed their behavior yet.”
“I do believe, however, that human behavior has been altered significantly by the lockdown in ways that are closing the gap between us and what's wild around our own homes — and that's great, up to a point,” she said.
She worries that animals may be pushed into closer conflicts with humans. “We have to interact with wildlife from a distance. That is because we still do not know all the diseases that, say, coyotes and rats carry with them.”
A century later, victory gardens connect Americans again
(AP) Kristin M, Hall, April 21
… Creating a victory garden now can be, as it was during World Wars I and II, a shared experience during hardship and uncertainty.
“World War I, to me, is a pretty stark parallel,” said Rose Hayden-Smith, a historian and author of “Sowing the Seeds of Victory: American Gardening Programs of World War I.” “Not only was there a war, but there was an influenza pandemic.”
… “So these gardening posters and food preservation posters would appear in literally dozens of languages,” said Hayden-Smith....“We don't have poster art, but we have Instagram,” she said.
Empty Grocery Shelves and Rotting, Wasted Vegetables: Two Sides of a Supply Chain Problem
(Inside Climate News) Georgina Gustin, April 19
"In terms of resilience and nimbleness, they seem to be able to pivot and figure out new supply chains quickly," said Gail Feenstra, deputy director of the University of California-Davis Sustainable Agriculture Research and Education Program (SAREP). "They're always struggling because of the competition that comes from the global food system. It puts many of them at a disadvantage. But now that system is in complete disarray. It allows these regional food systems to emerge. They're the ones that are bringing relief to communities."
… "This is more than a dress rehearsal. This is it," said Feenstra, of UC-Davis, referring to the disruptions caused by the pandemic. "This is going to be here for a while and it isn't the last time this will happen. This is an opportunity for our policy makers to invest in small and mid-scale businesses."
Is your tree on death's door? Here's how to tell
(LA Times) Jeanette Marantos, April 19
Climate change, invasive species and even international trade are taking a serious toll on California trees. An estimated 150 million trees died during the drought that started in December 2011, according to Smithsonian Magazine, and the stressed trees that survived became more vulnerable to attack by a host of newcomer pests, said Philippe Rolshausen, subtropical tree specialist for the Cooperative Extension office at UC Riverside.
"There are lots of invasive pests everywhere because of global warming and the movement of plant materials in general," he said.
Fresh Produce and Milk Go to Waste Even as People Need Food Amid Coronavirus Pandemic
(KQED Forum) Michael Krasny, April 16
Even as food banks are seeing more demand than ever, some California farmers are dumping milk and letting produce rot. The coronavirus pandemic has disrupted how we eat and in turn, how food is distributed. The closure of many restaurants, venues, and schools is leaving many food suppliers with excess perishables. Meanwhile, retailers and food banks are scrambling to keep food in stock. We talk with experts about how California's food supply chain has been disrupted, how it's adapting, and what to expect in the months to come.
Guests: Dan Sumner, professor of agricultural and resource economics, UC Davis
National Public Radio highlighted a growing concern for San Joaquin Valley tree fruit and nut farmers - diminishing winter chill in an age of climate change. "Warm winters mess with nut trees' sex lives," reported Lauren Summer on Morning Edition.
For example, adequate winter chill allows female and male pistachio trees to wake up simultaneously, which is ideal for pollen to be available for wind to carry it to blooms on female trees.
Fresno State agriculture professor Gurreet Brar, a former UC Cooperative Extension advisor, is testing whether horticultural spray application at different chill-hour intervals will trick trees into thinking they've been colder. Normally, the spray is used on fruit and nut trees to control insects, but it's also known to alter the tree's dormancy period.
"It's supposed to help the tree and buds wake up normally and have a normal bloom," Brar said.
Summer also spoke to Katherine Jarvis-Shean, UC Cooperative Extension orchard systems advisor in Yolo County.
"We're on this (climate change) march and it's really just a matter of how bad it's going to be, not whether it's happening or not," Jarvis-Shean said. "Threatening those crops is really threatening the livelihoods of a lot of Californians."
Fruit and nut trees that require the most winter chill will run into trouble by mid-century, when experts predict consistently warmer weather, Summer reported.
"Bing cherries, which is really the marquee variety in California, won't get enough chill," Jarvis-Shean said. "We'll need to be breeding new varieties that still have that rich ruby flesh and that juicy flavor that can do well under those low chill conditions."
Better-adapted trees may be the only strategy in the long-run, she said. Efforts are already underway to breed new varieties of pistachios that can handle warmer winters.
In the California agriculture industry, the climate change discussion is less about whether disruption is coming than it is about how farmers will adapt, reported John Cox in the Bakersfield Californian.
Cox spoke to a Delano farmer who doesn't like debating climate change, but he has thought a lot about how to deal with it.
"As a grower, you just take it as it comes," he said.
"Everybody I know in agriculture says, 'Yes, the climate's changing and adaptation to that climate change is crucial.' So that's not controversial," said Dan Sumner, director of the Agricultural Issues Center, a UC Agriculture and Natural Resources statewide program. "At the same time, that doesn't mean they buy into every public policy proposal for mitigating the climate change."
Climate change is likely to prompt farmers to grow different varieties or different crops.
But even as California agriculture may struggle to adjust to climate change, so will its competitors overseas, Sumner said. The real question is whether the state's farming climate will remain superior in relation to that of other countries producing the same crops, he said.
In the Washington Post, Adrian Higgins reported on the impact of climate change to agriculture across the nation. From Appalachia to North Carolina to California, milder winters are inducing earlier flowering of temperate tree fruits, exposing the blooms to increasingly erratic frost, hail and other adverse weather.
Breeders are working to develop new varieties, said Katherine Jarvis-Shean, a UC Cooperative Extension orchard systems advisor in Yolo County. But new trees typically take two decades of methodical breeding to create, exposing existing varieties to the vagaries of shifting winters and springs.
“The consumer will begin to know it's happening in the coming 10 to 20 years,” Jarvis-Shean said.
UC: Tariffs could cost fruit, nut industries over $3 billion
(Farm Press) Aug. 15
A new report released by the University of California Agriculture and Natural Resources' Agricultural Issues Center estimates the higher tariffs could cost major U.S. fruit and nut industries $2.64 billion per year in exports to countries imposing the higher tariffs, and as much as $3.34 billion by reducing prices in alternative markets.
Evacuation priorities: Save people first, then livestock

(SF Chronicle) Kurtis Alexander, Aug. 13
While misguided forest- management policies are just one reason that fire has become more devastating, a warming climate and more development in California's wildlands also contribute, making planned burning vital, said wildfire specialist Max Moritz with UC's Division of Agriculture and Natural Resources.
“We need to become more comfortable with fire as a tool,” he said. “Prescribed fire could do a lot of good, restoring these forests to healthy conditions and reducing the fire hazard.”

Drought may be increasing camel cricket numbers
(Farm Press) Tim Hearden, Aug. 8
A few years ago, University of California viticulture and pest management advisors noticed unusual leaf symptoms in certain Napa County hillside vineyards that were right next to oak woodlands.
As described by the UC Cooperative Extension's Monica Cooper and Lucia Varela, the feeding activity they noted in April 2015 resulted in a “lace-like” appearance to damaged leaves. Then last year, in March, they observed feeding damage to expanding buds.
… Where vineyards have come into play is when they were situated on hillsides next to oak woodlands and mixed species of white alders, madrone, California bay, and Douglas fir, according to Varela, a north coast integrated pest management advisor, and Rhonda Smith, a UCCE viticulture advisor.
Yes, humans have made wildfires like the Carr fire worse. Here's how.
(Washington Post) Sarah Kaplan, Aug. 8
…Many forests in the western United States are “fire adapted” said Scott Stephens, a fire ecologist at the University of California at Berkeley. Natural wildfires every 5, 10 or 20 years help clear debris from the forest floor and make room for stronger, healthier trees.
…Wildfires are as unstoppable as hurricanes, Stephens said — and much like hurricanes, increasingly inevitable as the climate changes. “But you could do a lot more when you're getting ready for fire to inevitably occur,” he said. By building with fire-safe materials, establishing buffer zones between ecosystems and communities, and better caring for forests before fire season starts, some of the destructiveness of fires could be mitigated, Stephens said.
The staggering scale of California's wildfires
(New York Times) Lisa Friedman, Jose A. Del Real, Aug. 8
…Lisa: Mr. Trump in his tweet referred to the longstanding dispute between California farmers and environmentalists over the allocation of the state's precious water resources. Both sides want more and Mr. Trump has embraced the arguments of the agriculture community.
But William Stewart, a forestry specialist at the University of California, Berkeley said leaving less water for fish would have no impact on amount available for fighting fires. That water comes from local streams and rivers, where water-dropping helicopters drop their buckets. Neither he nor other scientists could point to a scenario in which California's environmental laws have prevented or curbed the use of water to fight wildfires.
California giving out $170 million in cap-and-trade revenue to help prevent wildfires
(San Francisco Chronicle) Kimberly Veklerov, Aug. 8
…Groups in six Bay Area counties will get a combined $7.4 million. The biggest portion of that, $3.6 million, will go to UC Berkeley. The Federal Emergency Management Agency in 2016 withdrew what would have been an award of roughly the same amount to thin and remove eucalyptus trees in the East Bay hills after a lawsuit by conservation activists.
…Keith Gilless, chairman of Cal Fire, said the state needs to do much more vegetation management — activities like reducing hazardous plant fuels — to address wildfire risk.
“One of the things we need in California moving forward is striking a better balance between carbon sequestration in forests and the risk associated with that densely stocked carbon sequestration,” said Gilless, also a UC Berkeley professor of forest economics. “We need to figure out ways to do vegetation management that are socially acceptable with the smallest public subsidy possible.”
These California counties have the highest concentration of homes vulnerable to wildfire
(Sac Bee) Michael Finch II, Aug. 7
In the case of the northern counties, the risk will be higher because homes there often dispersed at the edge of a wildland area, said Lenya Quinn-Davidson, a Eureka-based fire advisor for the University of California Division of Agriculture and Natural Resources.
“Those areas that you mentioned are areas that have a lot of homes mixed into the wildland-urban interface — areas where there are a lot of homes that are edgy and in the forest and have a lot of fuel.”
Can More Logging Help Prevent California Wildfires?
(KQED) Forum, Aug. 7
Cal Fire officials announced yesterday that the Mendocino Complex fire grew to over 283,000 acres, making it the largest in state history. As wildfires across the state rage on, Governor Brown and some lawmakers are calling for increased forest thinning to lessen the threat posed by fires. Those in favor of logging say that removing trees and vegetation can help reduce a fire's intensity and make forests more resilient. Opponents say thinning does nothing to protect communities from fires and imperils species that depend on dense forests. We'll take up the debate.

(Sac Bee) Emily Cadei and Kate Irby, Aug. 7
“I think for a number of years the feds were more ahead of this dilemma, at least in discussions,” said Scott Stephens, a professor of fire science at the University of California, Berkeley. But “I have to say right now, I think the state is moving ahead. It's certainly being more innovative, it's doing more policy work.”

(Sac Bee) Dale Kasler, Aug. 6
William Stewart, a forestry management expert at UC Cooperative Extension, agreed. “The entity that's doing the worst job are the people working for him,” Stewart said, referring to Trump.
Stewart said the Carr Fire, which killed seven people and forced mass evacuations in and around Redding, started in shrub and grasslands west of the city, not in the forests. Only lately, after the threat to Redding abated, has the fire moved north onto Forest Service land and forested property owned by Sierra Pacific Industries, he said.

Cal Fire responds to President Trump's tweet about state wildfires
(ABC7) Rob McMillan, Aug. 6
Cal Fire and a researcher from UC Riverside responded to Donald Trump's tweet related to the state's wildfires on Monday.
"Thinning would be a good idea, but the question is how you thin properly," UC Riverside's Dr. Richard Minnich said.
"There are too many trees in the ground sucking the ground dry. That's one of the reasons you had so many trees die in the Sierras."
But Minnich says that there is plenty of water in California. Shasta is the biggest reservoir in the state and it's currently more than two-thirds full.
California Wildfires: It's a people problem
(East Bay Times) Lisa Krieger, Aug. 5
Even as fires rage across California, thousands of new homes are being built deeper into our flammable foothills and forests, as lethal as they are lovely.
A big reason why: It's harder to do controlled burns — one of the most effective fire suppression techniques — near residential areas, due to smoke concerns. Until the 1970's, fire suppression tended to minimize fire spread.
“If homes are sprinkled through the landscape, you take that key tool off the table,” said Max Moritz, a wildfire specialist with UC's Division of Agriculture & Natural Resources.
Report: Future climate could affect street trees
(Turlock Journal) Kristina Hacker, Aug. 3
Eighty-one years from now, Turlock's climate could resemble more of southeast California's high desert areas, according to a new report that says inland California municipalities should consider increasing temperatures due to climate change when planting street trees.
…"Urban foresters in inland cities of California should begin reconsidering their palettes of common street trees to prepare for warmer conditions expected in 2099 due to climate change," said the study's co-author, Igor Lacan, UC Cooperative Extension environmental horticulture advisor in the Bay Area.
Wildfires force California to reckon with a not-so-new normal
(Christian Science Monitor) Martin Kuz, Aug. 3
…The committee's focus on improving utility grid safety and examining the liability of power companies reflects the causes of several blazes in 2017. The absence of land use planning from its agenda suggests what Max Moritz, a wildfire specialist at the University of California, Santa Barbara, describes as a “political will problem.”
“If you want to keep communities safe, then you have to think about living differently, about where and how we build our communities,” he says. “But there's no bill in the legislature about that.”
Will smoke taint summer harvests in the Mother Lode?
(The Union Democrat) Giuseppe Ricapito, Aug. 3
Drift smoke from the Ferguson Fire has some Tuolumne County vintners and agriculturalists concerned about the commercial viability of the early fall grape harvest, but one forestry official with the University of California noted that the native wilderness of the Mother Lode has a developed adaptability to smoky conditions.
Susie Kocher, forestry and natural resources advisor with the University of California Department of Agriculture and Natural Resources Central Sierra Cooperative Extension, said that “smoke taint” of commercial agriculture was always a concern during fire season.
“It's grapes we worry about the most,” she said. “In the past there have been bad years when there was a lot of smoke where grapes were on the vine and wineries had to produce the smoky wine because of that effect.”
Coyote encounters expected to rise during heat and drought
(ABC 10) Jared Aarons, Allison Horn, Aug. 2
The record-breaking heat and drought are forcing animals, including coyotes, out of their natural habitats and closer to humans…
The University of California Coyote Catcher website tracks sightings and attacks. Their figures for 2018 show coyote incidents are down compared to last year. In 2017, there were 142 coyote attacks. More than halfway through 2018, San Diego is on track to stay below that number, with 64 attacks.
According to the website, there have been six reported pet deaths this year.
Backyard chickens are dying in droves in SoCal. Will disease spread to Valley?
(Fresno Bee) Robert Rodriguez, Aug. 2
Maurice Pitesky, a veterinarian and University of California extension specialist in the School of Veterinary Medicine at UC Davis, said backyard chicken owners should closely watch their flocks.
Symptoms include, sneezing, coughing, green watery diarrhea, neck twisting, paralysis, decreased egg production and swelling around the eyes and neck.
Growers prepare for smaller prune harvest
(Farm Press) Tim Hearden, Aug 2
…With guidance from University of California Cooperative Extension advisors, growers have been paying close attention to tree water stress and sugar levels in the weeks leading up to the harvest, which was expected to begin in about the third week of August.
… “It's probably going to vary a little bit because the cropping is really variable,” UCCE advisor emeritus Rick Buchner says of the prune crop. “Some of it is good and some is really light. We had a heck of a time pollinating them.”
…“Harvest can be a nerve-wracking time in the prune business,” UCCE advisors Franz Niederholzer and Wilbur Reil note in a California Dried Plum Board blog post. “The finish line – when the entire crop is in the bins – may be in sight, but here are still tough decisions to be made that influence your bottom line.”
…In general, harvest can be expected roughly 30 days after the first healthy fruit in an orchard starts changing color, UCCE orchard advisor Katherine Jarvis-Shean explains in a separate blog post. She urged growers to time their irrigation cut-off to improve dry-away ratios, reduce premature fruit drop and decrease shaker bark damage at harvest.
Researchers look at ways to improve onion yields

Abnormal Weather Takes a Toll on California Olive Crop
(Ag Net West) Brian German, May 30
The late winter freeze caused significant issues for several different commodities throughout the state and has been especially problematic for the California olive crop. The fluctuating temperatures have created substantial concern among the industry as bloom looks to be far below normal levels.
“Overall we're a little on the pessimistic side. The bloom, on the whole, has been pretty poor, many orchards actually have a very light, to next to no bloom at all,” said Dani Lightle, Cooperative Extension Orchard Systems Advisor for Glenn County. “There's an orchard here or there that looks pretty good, but on the whole, it is a little bit dismal.”
(LA Taco) Gab Chabran, May 29
…Eric Focht who is a staff research associate in the lab of Mary Lu Arpaia at UC Riverside through UC Agriculture and Natural Resources and the Department of Botany and Plant Sciences tells L.A. Taco that the recent avocado economy boom is “similar to what we see today with something like bitcoin.” He helps run a breeding program at UCR studying different avocados varieties, focusing mostly on Hass avocados but also looking at other less known versions of the popular fruit.
In short, he is working on breeding the perfect avocado that tastes great and is easier, faster, and less water-dependent to grow. This year is shaping out to be a good one for avocados, but this issue is always one to keep in mind.
Focht states that in the future, there will likely be more variety available in the mainstream marketplace. One varietal that Focht gets excited about is the Reed avocado which has now been popping up in places such as Whole Foods. It's known for its round, dinosaur egg shape and is about the size of a softball. It has a relatively large seed but the edible flesh is sometimes double or even triple that of a Haas that can make a lot more people happier per individual fruit.
(Chico News & Review) Ashiah Scharaga, May 24
When drifting clouds dapple the sky and vibrant wildflowers—tickled pink buds, honey-hued petals and virent stems—awaken in the verdant fields of Table Mountain, explorers quicken their pace. They spot trickling streams and grazing cattle. Occasionally, they look straight down, turning anxious eyes to their mud-slicked heels—did they step in one of the fertile cow-pie mines littered across the landscape?
That may seem a nuisance, but it's a necessity. Tracy Schohr, a livestock and natural resources adviser for University of California Cooperative Extension, said the natural magic of the popular Butte County recreational spot is made possible because of a long-standing grazing program. “If cattle were not actually on Table Mountain Ecological Reserve,” she said, “essentially those invasive species would choke out those native plants, and they wouldn't be there.”
… In the past, grazing was misunderstood and primarily viewed as destructive, said Dave Daley, a fifth-generation Butte County cattleman and associate dean of Chico State's College of Agriculture. He credits changing perspectives to the development of grazing science, fueled by people such as Schohr and Kate Wilkin, a UC Cooperative Extension forestry, fire science and natural resource adviser for Butte, Yuba, Sutter and Nevada counties.

Sheep Shearing 101: Why Aspiring Shavers Flock to This California School
(KQED) Tiffany Camhi, May 23
…“We try to get the students shearing the first day because they make a lot of mistakes,” says John Harper, head of the UC Cooperative Extension Sheep Shearing School in Hopland.
Harper says if you can make the right moves with your feet, everything else falls into place.
“We're dancing instructors,” says Harper. “It's like 'Dancing With The Stars' on steroids, but with sheep.”
Around this time of year, hundreds of thousands of sheep in California need to have their wool shaved off. But Harper says there's a shortage of sheep shearers worldwide.
That's why he started the school in Hopland about 25 years ago.
Dan Macon of the California Wool Growers Association says the growing popularity of backyard flocks in California (usually just a handful of sheep) is adding to the demand for shearers, too.
“Infrastructure of the sheep industry is a key component,” says Macon. “Having people with that kind of skill and willingness to work hard is desperately needed.”
AUDIO: Hey, Salad Lovers: It's OK To Eat Romaine Lettuce Again
(NPR Morning Edition) Allison Aubrey, May 23
…After a big foodborne illness outbreak linked to baby spinach back in 2006, the leafy greens industry put in place a number of procedures to prevent contamination. "Prevention became the major focus after that outbreak," says Michele Jay-Russell, a food safety researcher at the University of California, Davis.
"They set up intensive testing protocols to monitor water quality," Jay-Russell says. The industry also agreed on standardized setbacks — or buffers — to separate growing fields from livestock operations, which can be a source of E.coli contamination. "You want a safe distance from where you're growing fresh produce and where you have concentrations of animals, like on a feedlot or dairy," she says.
Are avocados toast?
(Grist) Nathanael Johnson, May 22
…When Katherine Jarvis-Shean was a doctoral candidate researching the decline of cold winters a few years back, she thought more farmers should be freaking out. “I used to think, ‘Why aren't you guys more worried about this? It's going to be the end of the world.'”
After all, many fruit and nut trees require a good winter chill to bear fruit. But after spending a few years as an extension agent for the University of California — working directly with farmers and translating science into techniques they can apply on the land — she understands better. It comes down to this: Farmers have a ton of concerns, and the climate is just one of them.
“If you decide what to plant based on climate, but then can't make the lease payment, that's not sustainable,” Jarvis-Shean said.
Lanternflies Eat Everything in Sight. The U.S. Is Looking Delicious.
(New York Times) Zach Montague, May 21
…Native to Asia, lanternflies first appeared in Pennsylvania in 2014. Despite a quarantine effort, they have also been discovered in small numbers in New York, Delaware and Virginia.
… “Most pests deposit their eggs on their host plant, or very close, so they already have food available,” said Surendra Dara, an adviser at the University of California Cooperative Extension.
“Those that have the advantage of being able to lay eggs on non-plant material obviously have a better chance of surviving and spreading,” he added.
Garbanzos are catching on in Yolo County
(Woodland Daily Democrat, Ag Alert) Bob Johnson, May 19
…“The largest part of our crop goes to canning, maybe 90 percent,” said Paul Gepts, UC Davis plant sciences professor and legume breeder. “California can only compete with high quality products. We have other varieties with higher yields, but the seeds are too small. The growers get a premium for larger, high quality seeds.”
Gepts developed the two newest UC garbanzo varieties, Vega and Pegasus. Both have large, attractive seeds well suited for the canning market, and both have resistance to Ascochyta blight, a fungal disease that can devastate the crop.
… “I think growers are more interested in garbanzos because it's a winter crop, and wheat prices are low,” said Rachael Long, UC Cooperative Extension farm adviser in Sacramento, Solano and Yolo counties. Long is finishing up UC's first Garbanzo Production Manual, which should be available before the end of the year.

Kale, Not Jail: Urban Farming Nonprofit Helps Ex-Cons Re-enter Society
(New York Times) Patricia Leigh Brown, May 17
Even by the standards of the Bay Area, where sourcing local, organic chicken feed is seen as something of a political act, the spectacle of 30,000 fruit and nut trees being tended by formerly incarcerated orchardists is novel.
…Jennifer Sowerwine, an urban agriculture specialist for the University of California Cooperative Extension at Berkeley, said that Ms. Haleh and Mr. Raders have “shifted the conversation around food justice.”
“It's not just about food security, but the security of providing living wages,” she said. That's no mean feat in a foodie monoculture.
Tough winter weather devastates local cherry, blueberry crops

Machines take over for people at Napa vineyard
(Capital Press) Tim Hearden, May 14
In the heart of the Napa Valley, a vineyard produces fine Cabernet Sauvignon with virtually no help from laborers.
The 40-acre “touchless vineyard” was established by Kaan Kurtural, a University of California Cooperative Extension specialist who has devoted much of his career to improving production efficiency in vineyards as labor shortages have worsened.
…When Kurtural started experimenting with vineyard automation 10 years ago, his primary goal was to save growers money in labor costs, he said. But since then, research has shown that grape quality is superior, largely because the tall canopy protects grapes from sun damage, he said. The system also uses less water than others, he said.
Dozens of strawberry growers gather in Santa Maria to learn latest industry advancements
(KSBY Staff) May 9
More than 100 farmers and growers took park in a meeting teaching them on the best way to grow a healthy strawberry.
The University of California put on the annual event which was free to the public.
Growers discussed improvements handling weeds, disease, and insects.
The Santa Maria Valley is the second largest strawberry growing area in California after the Salinas Valley.
The crop means a lot to people in Santa Maria.
"We've got a number of challenges to the California strawberry industry and we're doing are best to work together," said Steven Fennimore of University of California Cooperative Extension Agriculture and Natural Resources. "I'm optimistic that we'll find some satisfactory solutions."
Growers talked about all kinds of different ways to boost their crop including ways of using images from aircraft to detect stress in plants.
Pesticide Use on California Farms at Near-Record Levels
(Fair Warning) Paul Feldman, May 9
…Some experts say long-term changes in the mix of items farmers produce in California, including increases in almonds and other high value crops, give the agriculture industry the incentive to use more pesticides. Such crops present “a larger economic risk if pests are not controlled,”said Brad Hanson, a weed specialist at the University of California, Davis, plant science department.
Jim Farrar, director of the University of California's statewide integrated pest management program, added that more pesticides are needed when “you move from something like alfalfa and sorghum for dairies, where cosmetic injury isn't a problem … to something like oranges where if there's a blemish on the rind you get downgraded even if the orange is perfectly healthy.”
Cherry growers expect lighter crop yields
(Ag Alert) Ching Lee, May 9,
…Kari Arnold, a University of California Cooperative Extension farm advisor in Stanislaus County, said she's careful not to paint the 2018 cherry season as a disaster year "because it's really not." The crop may not be as robust, she said, but this was somewhat expected, because last year's crop was so big.
What wasn't expected, she said, was the freeze in the spring, which "did cause some damage to flowers." But the damage varied depending on the location of the orchard and whether growers were able to apply frost protection, she added.
"It's still going to be a good crop," she said. "It may not be the same as last year, but they're going to be good cherries. They're probably going to sell at a higher price because there'll be less of them."
She said she's concerned that word of it being a light crop may scare away field help, adding that "it's hard enough to get field labor in the first place anymore, because labor is becoming more and more difficult to come by and more difficult to keep."
Peak Avocado Is Yet to Come
(The Atlantic) Cynthia Graber, Nicola Twilley, May 9
…Its partners in evolution—the giant, elephant-like gomphotheres and three-ton ground sloths that dined on its fruit in return for transporting and then pooping out its giant seed—went extinct soon after the first bipedal apes arrived in the region. Rodents, jaguars, and eventually humans stepped in as dispersal mechanisms, albeit significantly less effective ones. The flourishing avocado forests that carpeted much of Mesoamerica dwindled and died out. And, as Mary Lu Arpaia, who runs the avocado breeding program at the University of California at Riverside, explained, the avocado became a backyard fruit, enjoyed by first the indigenous peoples and later the conquistadors, but rarely cultivated intensively—until recent decades.
Climate change ruining California's environment, report warns
(SF Chronicle) Peter Fimrite, May 8, 2018
“If I were going to look across North America, ground zero for climate change is the Arctic.

More illnesses with later onset dates linked to romaine outbreak
(The Packer) Ashley Nickle, May 8, 2018
Richard Smith, a University of California Cooperative Extension advisor based in Salinas, also said the outbreak is hurting sales.
“It's having an effect,” Smith said May 7. “This is the problem — lettuce is pretty expensive to grow, and you've got to cover your costs. You can lose money, at this point the bigger growers can afford to lose for a period of time, but then they've got to make it up, and it just makes it hard. We're not sure how the year's going to go.
“I guess the good news is that the consumers are being sophisticated enough to be focusing on the romaine (versus all lettuce) ... The reality is I guess the FDA doesn't want to clear romaine yet because they think that the lettuce from Yuma might have a 21-day shelf life, so until the FDA clears it and then that news gets clearly articulated, I think it's going to be a damper.
AEI economists say farmers have ‘beef' with Trump
(Hagstrom Report) May 7, 2018
…Daniel Sumner of the University of California at Davis also told The Hagstrom Report that farmers hurt by the administration's trade policies have "a beef" with Trump.
Sumner said that even though the tariffs on Chinese steel and aluminum have not yet gone into effect, California farmers including wine and almond producers are already worried. "Even if the tariffs don't happen, the rhetoric has effects," he said.
Sumner also said that Mexican buyers of U.S. dairy products — "reasonable business people in Mexico" — began months ago to contact New Zealand dairy producers about becoming a supplier because the Mexicans are worried about the impact of the North American Free Trade Agreement renegotiation.

Egg prices plunge as supplies rebound
(Capital Press) Tim Hearden, May 4
Commercial egg prices in California are plummeting, and a slow global economy combined with a rebounding chicken flock after last year's devastating avian flu outbreak are among the contributing factors.
…At first, Midwestern egg producers that didn't want to retrofit their barns simply avoided California. Those that did want to market to California found confusion in what actually constituted a Proposition 2-compliant cage, said Joy Mench, a University of California-Davis animal science professor.
“(T)he wording of Prop. 2 does not allow it to be regulated, so there is no official definition of what it means,” Mench said in an email. “That will have to be decided in the courts, either because there is a lawsuit or because someone is prosecuted.”
In enforcing the initiative, the CDFA uses the federal Shell Egg Food Safety rule, whose space requirement is larger than the United Egg Producer guidelines that most of the other states use, noted Maurice Pitesky, a poultry specialist at the UC-Davis School of Veterinary Medicine.
Farming takes center stage at Yolo County Fairgrounds
Woodland Daily Democrat) Cutter Hicks, May 4
Field trips to the fairgrounds led to a farming experience for students as the Yolo County 4-H and Farm Bureau hosted its 10th annual Farm Connection Day to kick off the Spring Show this weekend.
The four-hour event Friday featured more than 100 agricultural displays and hands-on activities for kids of all ages as nearly 2,500 visitors walked through the gates.
Farm Connection Day was open to the public and more than 200 4-H students teamed up to host the event — with a little help from adult volunteers. Their focus was to teach students of Yolo County the aspects of the organization before judging shows later that day.
DeAnn Tenhunfeld, a Farm Connection Day organizer, said that the attendance was the largest seen since she founded it in 2008.
Frost damage varied for California nut trees
(Farm Press) Robyn Rominger, May 2, 2018
Some almond growers experienced frost damage from recent freezing conditions, say University of California experts.
“There's really a lot of damage,” says Katherine Jarvis-Shean, UC Cooperative Extension orchard systems advisor for Sacramento, Solano, and Yolo counties. “The earlier varieties really took a hit. Some trees even dropped their nuts due to frost damage. It's pretty bad in some orchards.”
… Bruce Lampinen, UCCE almond and walnut specialist, measured temperatures in an almond trial at Davis, and notes that “Feb. 20 and 24 were the coldest days. It was very problematic because that's when the trees were in full bloom.” At full bloom, temperatures below 28 degrees F. can cause crop loss.
…Phoebe Gordon, UCCE orchard systems advisor for Madera and Merced counties, says, “From what I've seen and heard, the damage has been variable. Some orchards weren't hit that hard, and others were hit very hard. I think it depended a lot on micro-climate and what stage the trees were in. They become more susceptible to frost damage as they transition from dormant to full bloom, and to nut set. I don't think we'll really know until ‘June drop' is finished what the final load is.”
Dani Lightle, UCCE orchard systems advisor in Glenn and Butte counties, says, “Almonds were right in the middle of full bloom when the frost happened. Most of the orchards in my area seem to have escaped. We didn't seem to cross the threshold to where there was heavy damage. Of course, there are exceptions, but by and large we came out better in the end than we thought we would.”
New weapon in fight against walnut blight
(Farm Press) Robyn Rominger, May 2, 2018
Walnut growers have a new tool to help manage blight disease in their orchards — Kasumin 2L, manufactured by Arysta LifeScience, is the trade name for kasugamycin, and is available as part of a strategy to control the disease.
The new bactericide was discussed at a recent University of California Cooperative Extension breakfast meeting at Yuba City. “It's great to have another chemistry in the rotational loop for blight management in walnuts,” says Emily Symmes, UCCE integrated pest management advisor.
