UC ANR NEWS
The California fires situation is concerning, but not hopeless
The news that Americans are getting about California's devasting fires is not being hyped up by the media, said UC Cooperative Extension area fire advisor Lenya Quinn-Davidson on the nationally broadcast NPR program On Point.
Host Eric Westervelt of WBUR in Boston got a Northern California perspective from Quinn-Davidson, who works with communities in Siskiyou, Trinity and Mendocino counties on managing the threat of wildfires and is the Northern California coordinator of the California Fire Science Consortium.
"I definitely don't think the situation is being hyped up," Quinn-Davidson said. "I'm in Ukiah and there's a thick blanket of smoke. Everyone can feel the tension of the Mendocino Complex Fire."
Quinn-Davidson said she grew up in the vicinity and, back then, major fires like those burning today only happened every few years. Lately, such super fire seasons are happening every year. She said it's time for Californians to take a different approach when thinking about fire.
"Fire is the only natural disaster that we fight against," Quinn-Davidson said. "With hurricanes and earthquakes, we adapt and try to identify vulnerabilities and change our behavior. We haven't treated fire like that. We need to learn how to adapt and make changes that make us more resilient to fire."
On Point is NPR's only call-in program. One caller asked whether climate change has reached an irreversible tipping point at which little can be done to reverse the damage that is causing extreme flooding, heat, hurricanes and wildfires.
Quinn-Davidson said she offers hope to the people in communities she serves.
"They're not powerless," she said. "I don't want people to feel that we are beyond some tipping point and they should just throw in the towel. I think we need to feel empowered to make the changes we can make - whether on a personal scale, at at the mid-grade community scale, or if it is taking political action to make larger change ... We still have some place to make a difference. I really believe that."
Michael Mann, professor of atmospheric science and director of the Earth System Science Center at Pennsylvania State University, was also a guest on the On Point program. He said that, as a nation, we may have breached a different tipping point - a tipping point in public consciousness. Recent news reports have informed the public about extreme flooding in Japan, record-breaking heat in Europe and catastrophic wildfires in California.
"This summer has made a difference in the public perception of how profound the threat of climate change already is," Mann said. "And I like to think that when they go to the voting booths in less than 100 days, they're going to be thinking about climate change and the need to act on this problem. I think we will see progress."
Farmers concerned about crops tainted by wildfire smoke
When wildfires send smoke into farmland, orchards and vineyards, growers are concerned about the impact of the tainted air on their crops, reported Giuseppe Ricapitio in the Union Democrat.
"It's grapes we worry about the most," said Susie Kocher, UC Cooperative Extension forestry and natural resources advisor. "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."
The article said grapes are unlike other agricultural products, in that the skins are permeable. Free volatile phenols created by burning wood become part of the grape itself.
"It isn't something you can wash off," said Ron Harms of Yosemite Cellars winery.
After the 2013 Rim Fire, the winery produced a "Rim Fire Blend," which was successful. However, wine drinkers' palettes differ in terms of their smoke sensitivity. "Some people just can't tolerate (smoke flavor) at all," Harms said.
Other agricultural crops may not be impacted by a blanket of smoke, and some may even benefit. Before Europeans settled in California, Native Americans living in the wilderness would set fires to burn understory brush that built up in the forests.
"It's part of the ecological knowledge of native tribes that smoke is good for trees," Kocher said. "That's not a scientifically proven thing. We don't know."
More sensible land use planning can help prevent wildfire losses
Climate change is only partly fueling the catastrophic fires in California. Fire scientists also lay blame on the tendency of land use planners to allow the construction of houses and businesses in areas where wildfires are a natural part of the ecosystem.
Last week Gov. Brown forecast a rise in the number, intensity, and cost of fires, warning of “the new normal that we will have to face," reported Martin Kuz in the Christian Science Monitor.
Wildfire experts say its not a new normal but has become normal because lawmakers have avoided prodding local officials, developers, and residents toward an approach to land use planning that restricts housing growth in fire-prone areas.
Tomorrow's tinderboxes can be seen all over the Bay Area — from the new multi-million dollar dream homes packed along the edges of San Jose's Almaden Quicksilver County Park and Mount Diablo State Park to older residences, both modest and opulent, on peaks of the Santa Cruz Mountains and Oakland and Berkeley hills, reported Lisa Krieger of the Bay Area News Group. Similar growth is taking place in natural areas in other parts of the state, including the Sierra Nevada and Southern California.
An analysis by geographer Stephen Strader of Villanova University, published this spring in the journal Natural Hazards, found a 1,000 percent increase in the number of western U.S. homes at risk from wildfire over the past 70 years — from about 607,000 in 1940 to 6.7 million in 2010.
Housing near wildlands makes it harder to do controlled burns — one of the most effective fire suppression techniques — because of smoke concerns. Until the 1970s, fire suppression tended to minimize fire spread.
“If homes are sprinkled through the landscape, you take that key tool off the table,” Moritz said.
And as people develop rural areas, they're also more likely to ignite fires. In early California history, lightning was the major cause of wildfires. Now humans are the dominant cause of fires, from downed power lines, smoking, sparks from equipment and more.
“Now is the time to do smarter, stronger land use planning,” Moritz said, “so our future communities are not as vulnerable.”.

Poultry owners asked to monitor their birds for virulent Newcastle disease
Commercial and backyard poultry owners are asked to be attentive to their animals' health to help prevent the spread of the lethal and contagious virulent Newcastle disease now raging in Southern California, reported Bob Rodriguez in the Fresno Bee.
Symptoms of the disease include sneezing, coughing, green watery diarrhea, neck twisting, paralysis, decreased egg production and swelling around the eyes and neck, according to Maurice Pitesky, UC Cooperative Extension poultry specialist.
He said the popularity of backyard chickens is one of the challenges to controlling the disease. He estimates there are about 100,000 homes with poultry, with each home averaging five chickens.
"That is a lot more than in 2002, when we had the last outbreak (of virulent Newcastle disease)," Pitesky said. In 2002, the disease started in a backyard flock and eventually spread to 22 commercial poultry farms, killing 3.2 million birds.
"While people have the best of intentions, unfortunately a lack of biosecurity practices in people's backyards is one of the contributing factors of the disease spreading," Pitesky said.
Birds can become infected by coming into contact with other birds that are carrying the disease or by humans that carry the disease in their clothes or shoes. Pitesky said the disease also spreads when people purchase birds from a private party who may not be able to verify the bird is disease free.
He recommends buying from a hatchery or feed store that is affiliated with the National Poultry Improvement Plan, an organization that focuses on disease control.
“The goal is to be preventative,” Pitesky said.
If backyard chickens appear ill, owners should call the California Department of Food and Agriculture's State Bird Hotline at (866) 922-2473.
For more information on the disease, see the Virulent Newcastle Disease Outbreak Information and Resources page Pitesky has posted to his website, UC Cooperative Extension Poultry.

California's Wildfires Are Spreading Faster and Burning More This Year. Experts Say It 'Can Only Get Worse'
(TIME) Jennifer Calfas, July 31
…Rising temperatures aren't the only reason fires have grown in size and aggression, though scientists are quick not to place blame entirely on climate change. Urban development in vulnerable areas can make fires more devastating, and many of the state's most destructive fires were started by humans including the Carr Fire. Max Moritz, a specialist in cooperative extension at the University of California's Division of Agriculture and Natural Resource, says hotter temperatures have made fire seasons longer, too. Scientists see a direct link between rising temperatures and the amount of dry brush and ample fuel, which makes the fires fast-moving and often more explosive.
“There's good, solid research linking temperature increases to trends in fire activity,” says Moritz. “But it's really long-term trends.”

Firefighters Are Focused on Flames, Not Climate Change
(Scientific American) Kelsey Brugger, July 30
Climate change has exacerbated wildfires throughout America, and it's testing the people who fight them.
…Scientists are careful not to attribute any one wildfire to global warming, “but it sure looks like climate change,” said Max Moritz, a wildfire specialist in the Environmental Science, Policy, & Management Department at the University of California, Berkeley.

How California copes with Asian citrus psyllids
(Capital Press) Padma Nagappan, July 27
Huanglongbing, also known as citrus greening disease, has devastated the Florida citrus industry, and researchers and growers are working to prevent its spread to California's commercial groves.
…The disease is still confined to residential trees, but is spreading throughout Southern California — in Orange, Los Angeles and Riverside counties.
“That picture could easily change this fall, there's a lag time from when trees are infected and when we can tell that they're infected,” said Elizabeth Grafton Cardwell, an entomologist at the University of California-Riverside and the director of the San Joaquin Valley research center.

Portugal, the government is relying on an ancient firefighting technology: goats.
Last year deaths from wildfires in Portugal reached a record high of 106. This summer, however, hundreds of goats are being deployed to eat underbrush and dry vegetation that can serve as kindling. Working with goats “allows you to treat areas that are difficult to reach otherwise,” Dan Macon, a University of California Cooperative Extension livestock and natural resources adviser, told accuweather.com.
Phylloxera can also appear on own-rooted vines
(Western Farm Press) Tim Hearden, July 25
A University of California Cooperative Extension farm advisor cautions that even own-rooted vines can be susceptible to grape phylloxera, a tiny aphid-like insect that feeds on roots.
Lynn Wunderlich, a UCCE advisor based at Placerville, says some growers in her area are taken aback by the discovery of phylloxera in their own-rooted vines that are declining. The insect is thought to feed on certain rootstocks, stunting growth of vines or killing them, but it also can affect vines that are not grafted onto rootstock.

Minimize dust in vineyards for effective weed control
(Western Farm Press) Tim Hearden, July 25
In the hot summer months, activities in vineyards — as well as orchards and other farm fields — can kick up a lot of dust. And aside from causing soil erosion, tissue damage, reduced photosynthesis, and other troubles, wind-blown dust can complicate weed control, a University of California Cooperative Extension advisor says.
That's because dust can reduce the efficacy of glyphosate, which is an important tool for the management of weeds in vines and elsewhere, according to Lynn Sosnoskie, agronomy and weed science advisor based at Merced.

Could Coffee Be California's Next Cash Crop?
(San Francisco Magazine) Luke Tsai, July 24
The story of California's coffee experiment begins with Jay Ruskey...
In the many online videos you can find of Ruskey, who is 45 years old, he's charismatic and good-looking, with floppy hair, a toothy grin, and a distant resemblance to the actor John Krasinski. He isn't the first person to try to grow coffee in California, but he is the first to preach the gospel convincingly and to make a serious attempt on a commercial scale. It's an effort that stretches back more than 15 years, to when Mark Gaskell, a small-farm adviser with the UC Cooperative Extension program, handed Ruskey nearly 40 Central American coffee plants and helped him figure out how to get them to grow.

High-speed Wi-Fi at ag research center may be blueprint for rural communities
(RCR Wireless News) Susan Rambo, July 20
Outside the small San Joaquin Valley town of Parlier, 20 miles south of Fresno, California, the University of California's Kearney Agricultural Research and Education Center looms over farmland. Much more impressive in person than on Google street view, the center looks like a mini university campus — which is how KARE describes itself. Researchers have studied agriculture in this location since 1965, when local farmers pitched in to buy the land and donate it to the University of California Agriculture and Natural Resources (UC ANR). KARE is one of nine research and extension centers (RECs) under the umbrella of UC ANR around the state, one of which is nearby Lindcove (LREC).
… “I've been in Africa recently and the mobile coverage there was better,” said Dr. Jeffery A. Dahlberg, director of KARE, referring to some rural areas around the center. “It's embarrassing,” he said, given the relative wealth of United States.

You may not readily see it, but healthy spurs on this year's almond trees set the table for optimizing yields next year. And it could be a mistake to weigh in with a heavy hand when it comes to pruning trees.
Elizabeth Fichtner, University of California Cooperative Extension farm adviser in Tulare County, and Bruce Lampinen, UC walnut specialist with UC Davis, addressed those topics at a Central California Almond Day event in Fresno.
“All buds in the current year were formed the prior summer,” Fichtner said.

What is meat, anyway? Lab-grown food sets off a debate
(Wired) Matt Simon, July 16
…There could also be a middle ground here: marketing the new product as meat, but qualifying that designation. So “cultured meat,” or “lab-grown meat”—people have even thrown around “cell-based meat” (though technically speaking, all meat is cell-based). You can't, after all, just call your soy milk plain old milk. “Almond milk is obviously not the lactate of a mammary gland,” says animal geneticist Alison Van Eenennaam of UC Davis. “So I think probably there's going to have to be some other distinguisher so it's not mislabeled, because the FDA rules on labeling is it can't be false or misleading.And if it's labeled ‘meat,' you could make an argument that that's misleading.”

Parasite-borne illness spurs McDonald's to pull salads from 3,000 restaurants
(Los Angeles Times) Geoffrey Mohan, July 13
…“We are seeing more of these outbreaks popping up,” said Erin DiCaprio, a cooperative extension assistant specialist at the UC Davis' Department of Food Science and Technology.
The parasites are specific to humans and tend to spread through poorly processed sewage that may find its way into irrigation sources, DiCaprio said. “It's usually associated with produce that's from outside the United States,” she said.
There is no routine testing for presence of the parasite in the U.S. produce industry, in part because it has been difficult to develop a test in the laboratory, DiCaprio said. Many physicians also overlook testing ill patients for the parasite, according to the CDC.

Is It Safe to Eat Local Produce After a Wildfire?
(Pacific Standard) Sophie Yeo, July 13
…But the story could be different for another popular product of small-scale farming: eggs. Another study being undertaken by scientists at the University of California–Davis is examining how the ash distributed by the fires could have affected poultry and the eggs they produce. This group, too, has just received its first batch of data.
"Chickens are unique in that they spend 25 percent of their waking time eating off the ground. It's a worst-case scenario, where they really are products of the environment because they spend so much time ingesting it. Eggs are particularly worrisome because yolks are very fatty, and a lot of these chemicals are very fat soluble," says Maurice Pitesky, a veterinarian and epidemiologist working on the study. "It's a bit of a different risk factor from some produce. I would be very surprised if we didn't find something."

Firewise: Wildfire Preparedness Goes Beyond Horse Evacuation
(Paulick Report) Denise Steffanus, July 11
Dr. Kate Wilkin, forest and fire adviser for the University of California Cooperative Extension, said farm owners can take advantage of equine grazing habits — eating grass down to the nub — to protect the safety zone.
“Having heavy grazing around your structures and then feathering it out as you go farther away from the structures is one way to protect the property,” she said. “Of course, you want to be careful not to destroy that forage by overgrazing that will cause erosion.”
SAD story: Sugar disorder causes mid-season grape shrivel
(Western Farm Press) Tim Hearden, July 11
Among the most common headaches that grape growers encounter as their crop is developing is sugar accumulation disorder, or SAD, say University of California advisors.
Field studies involving E & J Gallo Winery and UC researchers have been under way near Clarksburg, Calif., to find solutions for SAD, which causes poor berry coloration and low sugar accumulation. It is triggered after veraison, according to Chuck Ingels of the UC Cooperative Extension in Sacramento County.

Amid trade turmoil, olive industry eyes U.S. market
(Western Farm Press) Tim Hearden, July 11
…As the state's tree nut sectors are advocating vociferously for a resolution to the budding trade war with China, the European Union and other countries, one crop that is largely unscathed by all the turmoil is olives.
That's because unlike most Golden State commodities, olive exports are minimal while import competition is robust, University of California-Davis agricultural economist Daniel Sumner notes.
“Olives are in a different situation,” Sumner said during a recent grower meeting in Orland, Calif. “The big difference for olives is they're not an export crop for the United States.”

Beginning at the 50:00 mark, Daniel Sumner discusses the effects of China's tariffs on California agriculture.
It doesn't need to escalate to take a hit. You have the direct hits of what's happening now, you also have the threat of future things happening. As you know, business including agriculture operates on expectations. I would say the biggest thing listeners should keep in mind is that as much as we focus on the announcement of the day, the announcement of tariffs on Chinese goods and the Chinese long-planned retaliation, those lists were put together months ago. Businesses were hoping it wouldn't happen, but planning for that.

But farm employment effects overall will be moderate at most.”

Five things you probably never knew about California's wildfires
(Mercury News) Patrick May, July 3
…Travis Bean writes in UC Weed Science blog that despite all the news coverage of last year's wildfires, “almost no source has identified the actual fuels involved for this most recent fire season or any other. As a weed scientist, this is a particularly alarming omission, especially when it's highly likely that invasive plants may have been partially responsible for exacerbating the intensity and spatial scale of many, if not most, of 2017's fires.”
