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
(Ag Alert) Kathy Coatney, Aug. 15
"It's generally too difficult to get trucks out on such a short notice," said Glenn Nader, University of California Cooperative Extension livestock and natural resources advisor emeritus for Butte, Sutter and Yuba counties.
… Carissa Koopmann Rivers, UCCE livestock and natural resources advisor for Siskiyou County, said the Klamathon fire, first reported in early July, devastated the town of Hornbrook, which is situated in a cattle-producing area.
…Ricky Satomi, UCCE forestry advisor for Shasta, Trinity and Siskiyou counties, said if there's a wildfire and a person has advanced notice, there are several things that can be done to save buildings before evacuating.
Tariffs Could Cost California Growers Billions

A new study from the University of California Agriculture and Natural Resources' Agricultural Issues Center finds that tariffs on 10 fruit and tree nut exports alone are estimated to cost the U.S. $3.4 billion annually.
Interior Secretary: Environmental policies, poor forest management to blame for wildfires
(Circa) Leandra Bernstein, Aug. 14
…"Together, poor land management, poor land use planning and the onset of climate change, we have created the perfect environment for the perfect firestorm in California. It's completely expected and it's going to get worse," explained Dr. Kate Wilkin, a fire scientist at the University of California Cooperative Extension.
Looming Chlorpyrifos Ban Has ‘Natural' Pesticide Makers Buzzing

In California's new wildfire reality, facing the need for periodic fires to clear fuel
(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.”

UCCE Manure Nitrogen Study Update in Dairy Feed Crops
(California Dairy Magazine) Aug. 10
It takes time for the nitrogen found in dairy manure water to become available to feed crops out in the field, and as dairy producers don't want to under or over fertilize their feed crops, the UC Cooperative Extension is conducting a research trial to find out more regarding how manure water interacts in the soil with plant root systems. Watch this brief interview UC Agronomy Advisor Nicholas Clark as he summarizes a recent presentation he shared at the Golden State Dairy Management Conference.
Trees vital as heat waves ravage Southland, experts and L.A. officials say

…Researchers with the University of California Cooperative Extension are helping do just that. In partnership with the United States Forest Service, researchers there have launched a 20-year study to identify trees that can withstand higher temperatures and lower rainfall. Native trees such as the Catalina Cherry and Ironwood trees, along with imports like Ghost Gum and Acacia trees, could form the future of L.A.'s canopy.

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 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?

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.
About 50 ranchers gathered this week in Willows to learn how they can convert straw left over from the rice harvest into a palatable and nutritious feed for cattle, reported Tim Hearden in Capital Press.
By baling rice straw before it dries and tarping it to keep the straw moist until it is fed to cattle, the feed, called "strawlage," is comparable to low-quality alfalfa, UC Cooperative Extension scientists say.
“We haven't figured everything out, but with the drought conditions as serious as they are, we feel the time is right to share our research with growers,” said Glenn Nader, the UCCE advisor who organized the field day.
Because of the drought, "There's going to be a significant problem with feed coming into this winter and rice strawlage may be an answer," said Peter Robinson, a UCCE specialist in the Department of Animal Science at Davis.
The feed can turn black and become a little slimy, but the cows don't seem to mind.
“The cattle do eat this really well,” rancher Herb Holzaphel said during the workshop. “It didn't feed as good as silage, but it fed better than normal straw.”
For more information, see the UC Rice Project website.

A story in the Los Angeles Times this week opened with the concerns of cattle ranchers. Without winter rain rangeland grass doesn't grow. Ranchers must decide whether to buy expensive feed or cull their herds to weather the drought.
"Their struggle is a bellwether for California's $45 billion agriculture sector," wrote reporter David Pierson. The repercussions will be felt beyond the state's borders. "The Golden State produces nearly half of all U.S.-grown fruits, nuts and vegetables and is the nation's leading dairy and wine producer."
Pierson quoted Doug Parker, director of the UC California Institute for Water Resources, in his article.
"The agriculture industry is definitely hit the hardest by drought," Parker said. "In California, agriculture uses 80 percent of water in the state. It's a major input for their business and hits their finances and employment directly."
The San Luis Obispo Tribune reported on drought hardships for SLO County fruit and vegetable farmers. Growers are facing increasing irrigation costs and taking steps to reduce salt buildup in the soil.
"The drought forces growers to prioritize crop cycles,” said Mary Bianchi, UC Cooperative Extension adviser. “What do you plant, and what do you leave fallow?”
In Stanislaus County, ranchers are expressing concerns about a trend among farmers toward planting almonds, reported the The Modesto Bee. Ranchers are worried the spread of almonds, walnuts an other high-value crops could strain their limited groundwater, drive up land prices and intrude on their way of life.
“It's not hard to understand why (farmers are planting more almonds),” said Roger Duncan, UCCE advisor. “It's very profitable.”
It was Duncan who provided the rough figures on almond profitability during the first day of the ninth annual summit of the California rangeland Conservation Coalition recently, wrote Bee reporter John Holland. Duncan said the net is even better for walnuts, which are not as extensive but still have had major growth in acreage. He also said the nut boom could be limited by a shortage of water and land.
The Drovers Cattle Network reported that cattle ranchers are seeking strategies for surviving the drought.
According to the article, rancher Billy McDonald's wife, Aileen, said she learned from UC Cooperative Extension farm advisor Glenn Nader that "you need to set a date, like if it doesn't rain by a certain date, to start culling. That's really important."
Also as part of the story, Roger Ingram, UCCE advisor in Placer and Nevada counties, advised ranchers to develop a drought plan.
Ingram warned against overgrazing and emphasized the importance of leaving enough residual dry matter in the ground to enhance seed germination and minimize soil erosion. With more bare ground, water would run off instead of soaking in, he said, and there would be less organic matter to feed soil microbes, resulting in fields being overrun by undesirable plants such as medusahead and yellow starthistle.
"Your grazing strategy should be take half, leave half," he said.
For those who are on irrigated pasture with limited water supply, UCCE advisor Larry Forero said fields are the driest in the summer but can get by with less water in the fall, so irrigate as close to evapotranspiration as possible and then stop irrigating. He also advised leaving four to five inches of stubble to facilitate pasture growth in the fall, should it rain or irrigation water become available.
When spring 2013 passed without a healthy rainy season, ranchers pinned their hopes on good growth in the fall. However rain came late, leaving pastures to wait for warm weather to get grasses growing again, reported Ching Lee in the Sierra Sun Times.
"Things may germinate, but they'll just sit there," said Glenn Nader, UC Cooperative Extension advisor for Yuba, Sutter and Butte counties. "There's not going to be any rapid growth until March — unless we get an unusually warm December."
The state needs successive rain storms this winter to fill the ground with enough moisture to support decent growth next year, Nader said.
In the meantime, ranchers will have to purchase feed, but prices are higher because the drought also pushed down production.
"People can quickly feed themselves into a negative cash flow with today's hay prices," Nader said. "That's why a lot of people are looking at alternative dry matter sources such as corn stover, rice straw and other things, to try and cheapen up those costs."
The story recounts how plant geneticist Mikeal Roose used irradiation on W. Murcott budwood to induce mutations that improve the fruit.
“Farmers have long selected citrus varieties that are low-seed, that have the same kinds of chromosomal rearrangements stimulated by the same thing—there’s natural radiation around all the time and it can affect the trees at any time.”
The advantage of inducing mutations, Roose explained, rather than waiting for the sun to trigger genetic variation, is that it can be targeted toward manipulating one particular feature—a kind of rapid prototyping for agriculture. The radiation accelerates the output of new genetic compositions. Each is then cultivated, screened and tested with the hope that at least one offspring will be reliably superior to its antecedent.
