How Do Wildfires Start?
(Live Science) Donavyn Coffey, Dec. 28
…In other words, "a source [of heat] hits receptive fuel that's dry enough to burn," said Lenya Quinn-Davidson, a fire analyst for the University of California Cooperative Extension forestry program in Northern California. In the right conditions, those three factors are all it takes to set a wildfire in motion.
…However, ignition is only the beginning. For a spark to grow into a sustained wildfire, there must be a perfect combination of factors, such as "dry conditions and really strong winds," Quinn-Davidson told Live Science. And because of climate change, dry conditions are lasting longer and, in turn, causing longer fire seasons.

Private woodlands lost to California wildfire — and may not be replaced
(SF Chronicle) Peter Fimrite Dec. 25,
…It costs about $400 per acre to reforest land, said Bill Stewart, a forestry specialist at UC Berkeley who has studied forest restoration programs after fires.
“A lot of (small property owners) ... don't have the cash or professionals to do the job,” he said. They “take a big financial hit when their forests are caught in a wildfire.”
…Max Moritz, a wildfire specialist at the University of California Cooperative Extension, said wholesale clearing is not always necessary. The rush to clear the land, he said, can result in healthy trees being cut down.
“Many trees can survive pretty bad crown scorch, so there's generally no urgency to get them out, or there shouldn't be, anyway,” said Moritz, an adjunct professor at UC Santa Barbara. “This is especially true of species that resprout, like several of the oaks and also redwoods.”
Get to know your wasps: University of California entomologist addresses misconceptions

Gene Editing Finds its Way to the Farm
(Dairy Herd Management) Clinton Griffiths, Dec. 21
…Alison Van Eenennaam, animal geneticist, University of California-Davis, says edits that create polled herds will soon be common.
“It's kind of like a pair of molecular scissors, if you will, that you can tell to go and cut the DNA at a very precise location in the genome,” Van Eenennaam explains. “What that enables you to do is go in and very precisely alter one particular gene of the thousands of genes that make up the genome, and you can introduce useful genetic variations.”
Farm Bill Set to Bring Several Benefits to California Growers
(AgNet West) Brian German, Dec. 19
...“There's some really good stuff in it for California, I mean first of all, getting a farm bill is fantastic,” said Vice President of UC Agriculture and Natural Resources Glenda Humiston. “Some really good things for beginning farmers and ranchers, and veterans' efforts in ag. One thing that's really potentially exciting for California in the rural development title is increasing the eligibility of communities up to 50,000 for some of the programs.”

Commentary: Is Atascadero prepared?
(Atascadero News) Ray Weymann, Dec. 14
…But often, even 10 feet from a house takes one into a neighbor's property. Whether this means mandating more aggressive tree and brush clearing, and reevaluation of building codes for new and existing structures, is something the new council should consider, availing themselves with input from our local fire department but also from people like Jack Cohen. Another wildfire expert, Max Moritz, suggests that governments must be more aggressive in not allowing development in areas especially vulnerable to wildfire.
Ceres Imaging unveils cumulative stress index
(Successful Farming) Laurie Bedord, Dec. 14
...“Findings over the last four years show that the average Ceres Imaging conductance measurement from its imagery over the season has provided the best correlation with applied water,” says Blake Sanden, a Kern County University of California Cooperative Extension farm adviser. “While there's no perfect predictor of final yield, Ceres Imaging aerial sensing of canopy plant stress has a significant relationship with final yield.”
New Farm Bill Provides Funds For Research In California ‘Ag,' But No Big Boons
(Capital Public Radio) Julia Mitric, Dec. 13
…"What's fascinating about the Farm Bill is, after all that hyper-partisan debate … it's really a lot of the same of what we already had," said Glenda Humiston, vice president of University of California Agriculture and Natural Resources.
Humiston is pleased that California will get an increase of $25 million a year for research of specialty crops, agricultural jargon for fruits, vegetables and nuts, as opposed to commodity crops like soybeans, corn and wheat. Those federal grants will cover many areas, from adapting farming to the effects of climate change to finding cures for California's many invasive pests, Humiston said.

…Sheep owners, particularly those with small flocks, have had trouble finding shearers for years—and the smaller their flock, the harder it is to get someone to shear for them because shearers are paid by the number of animals they shear, said John Harper, a UC livestock and natural resources advisor who has run the annual shearing program for nearly 25 years.
Could legalizing cannabis help the environment?
(Physics World) Kate Ravilious, Dec. 11
Using high resolution satellite imagery for the years 2012 and 2016, Van Butsic from the University of California, Berkeley and his colleagues found a boom in cultivation of cannabis in Mendocino and Humboldt Counties. By zooming right in, the researchers could identify the distinctive shape of the cannabis plants, the regular pattern in which the crop is planted, and the greenhouses perched in unusual places.
...“The chances of environmental damage are much greater in these regions because of the high potential for erosion, which threatens water quality, high potential for using water directly from headwaters, and the need to build roads to access these farms,” says Butsic.
What Does It Take To Defend Your Home Against A Mega Wildfire Like The Camp Fire? Here's How One Couple Survived
(Capital Public Radio) Ezra David Romero, Dec. 11
...Earlier this year, University of California system forest advisor Yana Valachovic toured the Carr Fire burn area in Redding.
“What surprised me there was how many of the stucco homes were lost and they were surrounded by green lawn,” Valachovic recalled. “What the mechanism of entry was is that they had a ring of vegetation right around the outside of their house.”
Susie Kocher, a forest adviser for the Lake Tahoe region with the UC Cooperative Extension, often works with homeowners that live within the Angora Fire burn area. That blaze destroyed about 250 homes in Lake Tahoe in 2008. A decade later, Kocher said people still aren't properly preparing their homes.
“There's still a lot of flammable plants planted right under picture windows,” Kocher said, adding that people have almost set themselves up for failure, “perhaps in the mistaken belief that they are kind of safe now because there's no big trees.”

Check out this video with Frank Mitloehner, Air Quality Specialist from the Department of Animal Science at UC Davis, who shared the facts, and read more about it in California Dairy Magazine.
Why Californians Were Drawn Toward the Fire Zones
(Wall St Journal) Jeffrey Ball, Dec. 7
…Lax building codes are at the base of the problem. Even in California, which has some of the toughest such rules in the country, they often aren't adequate or adequately enforced. The codes often dictate the use of fire-retardant materials in house construction but typically say nothing about how a development must be situated on the landscape—and that can help determine whether that development will burn in a fire, says Max Moritz, a cooperative-extension wildfire specialist at the University of California, Santa Barbara. “So the developers are able to come in, propose something, and often, without too much oversight, walk away after having built something in a dangerous place,” he says. “And we pick up the tab.”

Camp Fire Impacted Local Prescribed Fire Training
(My Mother Lode) Tracey Petersen, Dec 5
...The 20 participants were to get hands-on fire experience to better understand the art and science of fire management and ecology. However, organizer and Natural Resources Advisor at the University of California Cooperative Extension – Central Sierra Susan Kocher relays that due to the explosion of the Camp Fire no flames could be ignited for the training because the required back up resources were called to battle the mega blaze. She adds it is an ongoing problem regarding using prescribed burns for fire prevention. “I really think it shows just our exact dilemma. It's hard to get ahead of disasters because you're busy responding to disasters,” advised Kocher. “So, we just need to do everything we can to try and burn at all times of year to try to get ahead of these tragic wildfires that are happening.”

San Diego County wants to build 10,000 new homes in fire-prone areas
(San Diego Union Tribune) Joshua Emerson Smith, Dec. 3
…What these building codes and other rules don't take into account is whether a particular project should be built at all, said Max Moritz, a cooperative extension specialist in wildfire at the Bren School at UC Santa Barbara.
“There's all these hazards that we use to guide our building and our zoning from floods to landslides, and fire is not one of them,” Moritz said.
“In the end, the taxpayer is left holding the bill for all this,” he added. “The developer may do a really good job at designing and convincing everybody that it's the right thing to do, but after they walk away, the public is left doing fuels maintenance for decades, and the public picks up the bill when there's a disaster.”

California is a place forged by fire, and its fierce fire-fighting policies are creating fuel-filled landscapes that will burn hotter and faster than ever, reported Lisa M. Krieger in the San Jose Mercury News.
"Unless we change course, we'll never work our way out of this dilemma," said UC fire scientist Scott Stephens. "Unless we can get ahead of it, it'll never get better."
Strategies to live with fire were modeled at the UC Hopland Research and Extension Center when the Mendocino Complex Fire spread on its rolling oak woodland and chaparral landscape in late July. About 3,000 of the center's 5,300 acres burned.
In pastures where sheep had grazed, the oaks still have green leaves. In other areas not grazed since the 1950s, undergrowth provided a ladder for flames to reach oak canopies.
In areas were vegetation was reduced by grazing, "the fire was less intense. It skipped around more. It wasn't as complete a burn," said Hopland director John Bailey. "Having animals on the land reduced the hazard."
(Read more about the fire at Hopland in a blog post by community educator Hannah Bird.)
Prescribed burning is another strategy to maintain a forest that is resilient to fire.
“Prescribed burns are a really powerful and underused tool,” said UC Davis ecologist Malcolm North. When a wildfire hits pre-burned areas, “it just putzes along.”
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.

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.

Trump wants to clear more trees to halt fires. The feds need to spend more, experts say.
(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.”
Trump says California's water policies are making the wildfires worse. Is he right?
(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 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.

(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
(Ag Alert) Padma Nagappan, Aug. 1
Jairo Diaz-Ramirez and five other scientists have recently completed year two of an irrigation trial for onions, testing furrow and drip irrigation, and found that their methods produced good results, without water distress or soil tension. They tested the Taipan variety of onions.
Farmer Vang Thao has been managing a successful farm south of Fresno for nearly 30 years, producing a spectacular array of vegetables – heirloom tomatoes, purple bell peppers, water spinach, bitter melon, Thai eggplant and dozens of others.
Every weekend the family traverses the Grape Vine to set up a visual feast at farmers markets in Santa Monica, Hollywood, Palos Verdes, Torrance and Hollywood. Acclaimed Los Angeles chefs rave about his produce, according to a Los Angeles Times feature story on the Thao family.
Produce like sweet potato leaves, amaranth and black nightshade are essential for families hailing from Vietnam, Laos, Thailand, the Philippines and India who seek ingredients for their traditional cuisine, but the market is limited. Now, small-scale farmers like the Thaos are on the cusp of something with much wider appeal.
One of their crops is moringa, a tropical tree that produces an abundance of fresh shoots to sell at the farmers market booth for $1 a bundle. Moringa is a delicate green that can be added to salads, soups and nearly any other dish. It has a pleasant nutty, earthy and slightly pungent green flavor. While it tastes good, it's the plant's nutrient profile that is commanding attention.
On the internet, moringas are called miracle trees. All parts of the plant are edible – the tender leaves can be cooked or eaten fresh, moringa flowers are considered a delicacy, the tree's young pods can be used like green beans, roasted seeds are said to have antibiotic and antifungal properties. The roots and bark have medicinal potential, but need more study to determine the right dose. A 100 gram serving of moringa greens has more protein than a cup of milk, more iron than a cup of spinach, and is high in calcium, potassium, vitamin C and vitamin A.
Moringa is the Superfood of 2018, according to the trend watchers at SPINS.com. UC Davis nutrition researcher Carrie Waterman is studying moringa's use, production and processing worldwide. She is pursuing moringa for therapeutic applications in treating cancer, HIV and inflammatory bowel disease.
Ruth Dahlquist-Willard, the UC Cooperative Extension advisor to small-scale farmers in Fresno and Tulare counties, recognized moringa's potential to supplement income for Southeast Asian farming families who are marketing specialty Asian vegetables and herbs to immigrant communities.
“Moringa is a drought tolerant tree known for its excellent nutritional content,” Dahlquist-Willard said. “We believe it could improve the economic viability of small-scale farms in our community. We are helping small-scale farmers with moringa product development and marketing.”
Supporting farmers growing moringa in marketing the product to new buyers is an objective of the UCCE moringa project, a partnership with the UC Sustainable Agriculture Research and Education Program, which was funded by a California Department of Food and Agriculture specialty crop block grant. Lorena Ramos, the project lead, is working on developing marketing materials, outreach opportunities, and value-added options.
While using moringa is second nature for many immigrant groups, expanding the market includes demonstrating how easily the green can be used in the kitchen. Dahlquist-Willard and Ramos called on another sector of UC Cooperative Extension – the UC CalFresh Nutrition Education Program – for assistance. UCCE offers nutrition education in schools and community settings to children and families eligible for the USDA's nutrition assistance programs. Each year, Fresno State dietetic students serve two-week internships at UCCE. In 2018, one of their tasks was developing creative, healthful recipes incorporating moringa. Among the recipes were overnight oatmeal, pesto, smoothies, guacamole and energy bites – all with moringa.
“We are publishing the best recipes to share with the public to help them add this nutritional green into their diets,” Ramos said.
Recipe cards and moringa samples will be available July 26 at the Fresno Food Expo, where UCCE is hosting a booth to raise awareness about moringa by introducing farmers to Fresno area chefs, buyers and consumers and sharing information about the vegetable's health benefits, culinary versatility and its ability support small-scale farmers in Fresno and Tulare counties.
Following is a USDA recipe ideal for incorporating moringa:
Grilled quesadilla with vegetables
Nonstick cooking spray
1 medium zucchini, diced
½ broccoli head, diced
1 green pepper, diced
1 medium onion, minced
1 carrot, peeled and grated
16 (6 inch) flour tortillas
12 ounces cheese, shredded
½ cup moringa leaves
- Wash all vegetables.
- Collect, dice, shred and measure all ingredients before starting to prepare the recipe.
- Spray a large skillet with cooking spray. Add zucchini, broccoli, green pepper, onion and carrot. Cook vegetables on medium heat for 4 to 5 minutes, stirring frequently. Remove vegetables from skillet, and put on a clean plate.
- Spray skillet with cooking spray again and place 1 tortilla in the skillet. Top with ½ cup vegetables and 1/3 cup cheese. Sprinkle on fresh moringa leaves.
- Place a second tortilla on top. Cook on medium low heat for 2 to 3 minutes or until the cheese starts to melt and the bottom tortilla starts to brown.
- Flip over the quesadilla. Cook for another 2 to 3 minutes until tortilla brons.
- Repeat steps 4 through 6 to make additional quesadillas
- Cut each quesadilla in half or quarters, serve hot with your favorite salsa or other toppings.
- Refrigerate leftovers within 2 hours. Eat within 3 to 5 days.
Agricultural advances draw opposition that blunts innovation
(Science) Anne Q. Hoy, June 29
Scientists are using technology to expand global food production and ease its environmental impact, but advances are being challenged by claims that lack scientific evidence and raise public distrust and concern, a leading agricultural scientist told an American Association for the Advancement of Science audience.
Alison Van Eenennaam traced the advent of campaigns against agricultural innovations related to areas from cattle and chicken production systems to plant biotechnology. The impact such efforts are having on agricultural advances was the focus of the ninth annual AAAS Charles Valentine Riley Memorial Lecture on 5 June at the AAAS headquarters in Washington, D.C.
UC Davis Experts Help Farmers, Ranchers Profit in Growing Trend
(Cal Ag Today) Patrick Cavanaugh, June 29
Many farmers could benefit from agritourism and the added value it brings, but developing successful agritourism operations can be tricky. Experts at the Agricultural Sustainability Institute (ASI) at UC Davis are helping farmers and others in the agricultural community understand the regulations, permits, insurance, marketing and other considerations needed to succeed.
“Agritourism operations are more successful when they're part of a supportive community of tourism professionals, county regulators, agriculture regulations and others,” says Gail Feenstra, ASI's food, and society coordinator.
Feenstra and her team recently received a $73,000 grant from Western Sustainable Agriculture Research and Education, a U.S. Department of Agriculture program, to develop training, resources and peer support for farmers and ranchers considering agritourism. Feenstra is working with Penny Leff, ASI's statewide agritourism coordinator and team project manager.

Answer to how urban coyotes thrive is not for weak-stomached
(Texarkana Gazette) From the LA Times, June 29
This scientific study is a coyote postmortem on an unprecedented scale—it has so far documented the contents of 104 stomachs and intends to examine 300 by the end of the year. The team, led by Niamh Quinn, UC Cooperative Extension's human-wildlife interactions advisor, is already generating a wealth of data to better understand how these omnivorous canids sample everything from pocket gophers to hiking boots while managing to survive in a land of 20 million people.
Mechanized vineyard saves labor, boosts quality
(Western Farm Press) Tim Hearden, June 27
Kaan Kurtural started working on a fully mechanized vineyard to help growers save on labor costs, but then he noticed it also produced grapes with superior quality.
“We made wine from these last year and compared it to our traditionally-farmed vineyards,” says Kurtural, a specialist in the University of California-Davis Department of Viticulture and Enology. “Until we tell people what it is, they can't distinguish the quality of the fruit or the wine.”
He demonstrated the 40-acre experimental vineyard during a recent field day at the UC-Davis Oakville Station north of Napa. About 200 winegrape growers, vineyard consultants, and other industry representatives attended.
Several methods available to control vineyard weeds
(Western Farm Press) Tim Hearden, June 27
As most fumigants in California are being phased out, growers are having to find other ways to control weeds in young vineyards.
And while weeding by hand has been done, increased costs and a shrinking labor force have made this task impractical, says John Roncoroni, University of California Cooperative Extension Weed Science Farm Advisor in Napa County.
New podcast offers advice to California farmers
(Capital Press) Padma Naggapan, June 26
Two enterprising farm advisors with the University of California's cooperative extension have begun a podcast that will focus on tree crops and other produce grown in the Central Valley.
Called “Growing the Valley,” the podcast will have a new episode every two weeks, with each episode focused on news growers can use, such as managing specific pests, irrigation techniques, alerts about what to watch out for, and what tasks to take care of at particular times of the year.
Proactive Pawnee Fire response in Lake County seeks to avoid another catastrophe
(SF Chronicle) Lizzie Johnson, June 25
“I've never seen so much focused attention in Sacramento on the issue,” said Keith Gilless, a professor of forest economics and dean of the College of Natural Resources at UC Berkeley.
“Last year, 2017, got everybody's attention,” said Gilless, chair of the California State Board of Forestry and Fire Protection. “Last year was just terrible. Everybody involved is doing their best to be as prepared as we can. Any area might burn now, including those with much higher structure densities than they did 20 or 50 years ago.
“You are going to need a lot of resources that you might not have needed before,” he said. “The state is being very aggressive in its suppression efforts.”
UC's Humiston welcomes visiting Chinese ag scientists

With vineyard labor scarce, Napa growers warm up to machines
(Napa Valley Register) Henry Lutz, June 24
On a recent morning at the UC Davis Oakville Experimental Station, extension specialist Dr. Kaan Kurtural walked along the edge of an especially tall block of Cabernet Sauvignon.
Planted in 2016, the block hosts 1,340 vines and produces roughly 15 to 18 pounds of fruit per vine. “So it'll be yielding quite nice,” Kurtural said as he walked down the 62-inch tall rows.
Far more notable than the vineyard's fruit, however, is how it gets farmed.
“There are no hand practices out here,” said Kurtural. “Everything is done by machine.”
Early Detection Key to Managing Ceratocystis Canker in Almonds
(Growing Produce) Dianne Munson, June 22
...Based on a statewide survey out of the Department of Pathology at University of California, Davis, canker diseases are the primary cause of tree death in almond orchards, and Ceratocystis canker is one of the most prevailing canker diseases found in California. This canker disease is aggressive, but it doesn't have to mean disaster.
“If you know what to look for, the disease is manageable,” says Florent Trouillas, UC Cooperative Extension Specialist, Department of Plant Pathology, University of California, Davis.
California has 27M more dead trees than in 2016, but numbers may be easing in some areas
(Ventura County Star) Cheri Carlson, June 22
“Trees aren't getting moisture that they need to be healthy and they're stressed,” said Susan Kocher, a natural resources adviser for UC Cooperative Extension. “We had a huge insect outbreak because of the drought.”
Kocher, based in South Lake Tahoe, focuses on the Central Sierra, where stands of ponderosa pines were hit hard by beetle attacks.
…The highest risk of fire is when trees still have their needles – the so-called “red and dead” phase, Kocher said. Green needles turn red, and those dried-out needles are a particularly flashy fuel, like tinder in a campfire. Once the needles fall off, the risk drops a bit.
Chinese scientists visit Tulelake
(Siskiyou Daily News) Danielle Jester, June 20
The University of California Agriculture and Natural Resources Intermountain Research and Extension Center in Tulelake hosted a group of scientists from Chinese universities on Sunday; the scientists are on a tour of agriculture in northern California through June 22.
University of California Vice President of Agriculture and Natural Resources Glenda Humiston explained the purpose of the tour, noting, “The Chinese face many of the same issues that we do here in the U.S. The Chinese universities want to improve rural economic development to lift up the quality of life for people in rural communities.
“They are also responding to global climate change, drought and pests while trying to improve food security and water use efficiency. They see UC Cooperative Extension as an effective research model; we hope that scientific collaborations will accelerate solutions and help maintain relations for California agriculture with China.”

With wildfire season at hand, California on slightly safer footing this year
(SF Chronicle) Kurtis Alexander, June 17
… But as significant, and plentiful, as the new fire-protection measures are, they merely nip at the edge of an underlying issue: that fire is a constant in California, and as long as people choose to live in and around the state's wildlands, experts say, the threat remains.
"I would not be surprised if we have another big fire," said Bill Stewart, forestry specialist at the University of California, Berkeley. "I just don't think we're where we need to be."
… “We really haven't put together the pieces of a resilient fire strategy in local areas,” Stewart said.
Reducing food waste to combat world hunger
(Morning Ag Clips) June 17
One-third of the world's food is spoiled or tossed rather than eaten, a fact that is tragic when nearly one billion people go hungry. The injustice of food waste is worsened by the fact that food decomposing in landfills emits greenhouse gases that contribute to climate change.
UC Cooperative Extension is working closely with the cities and county of Santa Clara in a far-reaching program to divert organic matter – food and green waste – from landfills by composting and using the product to enrich soil in the home garden.
From dendrometers to drones, devices drive ag-tech boom
(Farm Press) Tim Hearden, June 16
Agriculture across the country is going high-tech, and California is leading the way as the tree nut and other industries are looking for ways to save water.
Agriculture across the country is going high-tech, as the ag and food sectors invested $10.1 billion in digital technologies in 2017, according to a University of California study. That's up from $3.2 billion in 2016, reports the UC's Giannini Foundation for Agricultural Economics.
In California, which was the leading state last year with $2.2 billion spent to adopt new technologies in ag and food production, UC Cooperative Extension researchers are researching or developing lots of new, innovative ideas. And growers are putting them to work in their fields and orchards.

Overburdened growers fuel an ag-tech investment boom
(Western Farm Press) Tim Hearden, June 14
…While ag was slower than some other industries at adopting digital technologies, farm and food sector investments in these technologies zoomed to $10.1 billion nationwide last year, up from $3.2 billion in 2016, according to a new University of California report.
California was the leading state for ag-tech investments with $2.2 billion in 2017, or 22 percent of the total, and ag and food producers in the Golden State spent $5.1 billion on new technologies between 2012 and 2017, reports the UC Giannini Foundation for Agricultural Economics.
UCD Oakville Field Day Highlights: Trellis Trials, Red Blotch Vector Update, Mechanization Tools
(Wine Business) Ted Rieger, June 12
The University of California, Davis (UCD) hosted its annual Grape Day at the Oakville Station experimental vineyard in Napa Valley June 6 with talks and presentations by UC Cooperative Extension specialists, and presentations and equipment demos from vineyard industry suppliers.
UCD viticulture extension specialist Dr. Kaan Kurtural showed a trial planted in 2016 with six different trellis systems designed for mechanical harvest in a 1-acre block at the experimental vineyard using Cabernet Sauvignon 08 on 3309 rootstock. The six trellis types include: a traditional vertical-shoot- positioned (VSP) trellis as a control; a single high-wire system designed for mechanized management; a high-quad system; a cane-pruned system with 12-inch cross arms for a sprawl-type canopy; and two versions of a relaxed VSP, one with a T-top post for a wider canopy.

Why a Decline in Insects Should Bug You
(Wall Street Journal) Jo Craven McGinty, June 8
Entomologists want to put a bug in your ear: Insects are necessary for the survival of mankind.
“It's the classic third-grade food chain,” said Richard Redak, an entomologist at the University of California, Riverside, and co-author of the book “Bugs Rule!” “If you pull insects out, you've got a problem.”
…“Any organic product in a human's life probably has a beneficial insect and a pesty insect,” Dr. Redak said. “The pesty ones are an incredibly small fraction of the total. Those that are not a problem are critical to the ecosystem.”
Brown Marmorated Stink Bug Officially Deemed Pest of California Almonds
(Growing Produce) David Eddy, June 7
Brown marmorated stink bug (BMSB) is certainly not new to California growers, but in the wake of some more troubling finds, it is now officially a pest of almonds.
Almonds are now listed as a preferred host on the Stop BMSB website, which was created by a team of researchers from all over the country dedicated to finding a way to stop the pest from damaging a wide range of crops.
One of those researchers is Jhalendra Rijal, University of California Cooperative Extension Area IPM Advisor for San Joaquin, Stanislaus, and Merced counties, who said the first such damage was just two years ago, when they were found in peaches. The actual first finding in the state was three years before that, in Sacramento, but despite being a very large find, they never appeared to spread, adding to the mystery of BMSB movement.

… Van Eenennaam, whose program at UC-Davis focuses on research and education around the use of animal genomics and biotechnology in livestock production systems, explained the value of gene editing. For example, research is underway to utilize gene editing to prevent such diseases as African swine fever in hogs and tuberculosis in cattle.
“What better way to approach dealing with disease than through genetic improvement?” she noted.
Use of gene editing to introduce the polled trait into elite germplasm
(Progressive Dairyman) Alison L. Van Eenennaam and Maci L. Mueller, June 4
Physical dehorning of dairy cattle is a standard practice to protect both human dairy workers and other animals from injury. However, it is not only costly for producers, but also painful and stressful for the animals. As a result, dehorning is currently facing increased public scrutiny as an animal welfare issue. Despite these factors, 94 percent of U.S. dairy cattle producers report routine dehorning.
Early Ripening Grapes Could Revolutionize Raisin Production
(Growing Produce) Matthew Fidelibus, June 2, 2018
The USDA-ARS raisin grape breeding program has long focused on the development of early ripening varieties. Early ripening allows drying to begin sooner, thus helping to avoid inclement weather and enable production of dry-on-vine (DOV) raisins. ‘Fiesta' and ‘Selma Pete' are examples of early ripening raisin grapes from the USDA that have helped change the way California raisins are made.
