Coyote sightings are on the rise in San Francisco, even taking naps in patches of green spaces in the city, reported Uma Chrobak in Popular Science. However, it is unlikely they indicate a change in wildlife behavior, said UC Cooperative Extension human-wildlife interactions advisor Niamh Quinn.
Officials believe the increased sightings may have more to do with a change in human behavior. Many people are at home and bored, so they may staring out the window and going on more walks in their neighborhoods.
Quinn follows five radio-collared coyotes in Los Angeles for a research project. She says her coyotes haven't changed their routines since the shelter-in-place order went into effect, staying in their respective territories, which include areas near a shopping mall and golf course.
The number of coyotes reported in San Francisco on Quinn's Coyote Cacher website isn't unusual, she said.
“People are just at home noticing more things,” she said, "especially in California, we're not all spending five hours a day on the freeway [now], you know?”
If you see coyotes or other wildlife, give them space, Quinn said. “It's very important to keep wildlife wild,” she said. “You should never feed wildlife.”
Are Blackouts Here to Stay? A Look into the Future
(E&E News) Anne C. Mulkern, Nov. 15
…Throughout the United States, between roughly 2000 and 2010, about 75% of homes that burned in wildfires were located in the WUI, said Van Butsic, a land use specialist at the University of California, Berkeley. The rest was mostly in rural areas, with about 2% in cities.
People go back after they lose homes, Butsic said. He surveyed the 28 largest fires in California from about 1975 to 2005, and through aerial photos tracked what was rebuilt. About 90% of destroyed homes were rebuilt within a decade, he found. New homes also filled in large tracts of undeveloped land in formerly burned areas.
Climate Considerations for Processing Tomatoes
(AgNet West) Nov. 15
Research models show that increases in overall temperatures in California will have a direct effect on how some crops are going to be produced in the future. In one study looking at processing tomato production in the Central Valley, researchers found that changing temperatures will likely have a noticeable impact on the timing of the growing season.
“We looked at the data all the way starting from 1950, into the future by 2030-2040 and see how the time of maturity is changing,” said Tapan Pathak, UC Specialist in Climate Adaptation in Agriculture. “What we saw is, in general the time from emergence to maturity, the timeframe for processing tomatoes in that region, is going to shrink down almost by two to three weeks.”
What's Growing On: American rose trials test sustainability
(Stockton Record) Marcy Sousa, Nov. 15
Did you know San Joaquin County Master Gardeners have been part of a National Rose Trial since 2018? The trial is part of the American Rose Trials for Sustainability (A.R.T.S.) program that has trial sites across the United States. It was initiated in 2012 by individuals representing multiple rose stakeholder groups, including: industry, the scientific community and public gardens. There are only two Mediterranean climate trial locations and both are in California. The trials at the Fullerton Arboretum started in 2019 and the UC Cooperative Extension office in San Joaquin County began in 2018.
…Our Environmental Horticulture Advisor, Karrie Reid, has been managing and overseeing the trial since 2018. Our roses were planted in unused turf areas that were converted to the trial grounds. One of the selling features of converting the turf sections was the calculated water savings: 3,656 square feet of turf used 103,000 gallons of water, while 60 roses in the same area on drip use 6,175 gallons, a 94 percent savings. Trial sites are covered with a 3-inch layer of wood mulch.
Report: California ag is a major economic driver for the state
(Agri-Pulse West) Brad Hooker, Nov. 13
A new report by the University of California Division of Agriculture and Natural Resources (ANR) adds new dimensions to the “massive economic juggernaut” of the California agricultural industry. The findings reveal that agriculture contributed more than $263 billion to the economy in 2018 through direct sales and employed more than 1.2 million people, while benefiting urban and rural regions alike.
The report examines the entire “working landscape,” which also includes fishing, forestry, mining, outdoor recreation and renewable energy, in addition to agricultural distribution, production, processing and support. Together, the sectors represent $333 billion in sales, 1.5 million jobs and 6.4% of the total California economy, outranking the healthcare, real estate, construction and retail sectors. Agriculture accounted for 85% of the working landscape businesses and 79% of the sales income. According to ANR Vice President Glenda Humiston, the working landscape likely surpasses the finance sector as well.
UCCE Addressing Watergrass Issues in California Rice Fields
(AgNet West) Brian German, Nov. 13
Researchers from UC Cooperative Extension (UCCE) are looking closely at the watergrass issues in California rice fields to get a better understanding of the problem. Watergrass has historically been a fairly common weed species that growers face, however in recent years the issue has been compounded by a number of factors. Several watergrass species have demonstrated resistance to the materials available and it appears that one or two new species may have emerged.
“In the past few years watergrass is becoming more and more of a problem, whether it's the ones that we know that we have or these possible new species,” said Whitney Brim-DeForest, UC Rice Farm Advisor serving Sutter, Yuba, Placer, and Sacramento Counties. “It's just becoming more difficult to control with the herbicides that we have.”
Experts Warn Of Surge In Sudden Oak Death Infections In North Bay

“And then, of course, these limbs that have just fallen off,” said Kerry Wininger of UC Cooperative Extension as he stood beneath a dying tree in Sonoma County's Fairfield Osborn Preserve. “And big patches will come out at once.”
Wininger is with the UC team working to measure the problem, and the numbers are up dramatically. She oversees a yearly survey conducted by volunteer citizen scientists.
…“For Sonoma County in general, Sudden Oak Death numbers look about double where they were last year,” said Wininger. “So it's actually increasing at a rate a little bit faster than we would expect.”

California's Wildfire Policy Totally Backfired. Native Communities Know How to Fix It.
(Mother Jones) Delilah Friedler, Nov. 11
…“We aren't anywhere near bringing fire back at the scale we need to,” says Lenya Quinn-Davidson, a fire advisor with the University of California Cooperative Extension who helped lead that burn. “It's important to push forward with a grassroots model that empowers people to do the work, instead of having bottlenecks with the agency that's in charge.”
The Humboldt County Prescribed Burn Association, which Quinn-Davidson leads, was the first organization of its kind in the West when it started in 2018, and has already inspired similar groups to start up in northern California's Plumas, Nevada, Sonoma, and Mendocino counties. These groups bring landowners and neighbors together to provide the manpower that controlled burns require. Quinn-Davidson says she's hosted 25 lecture and field-based workshops in the past year to increase people's comfort with prescribed fire, and in the past two years, she's led 20 burns on private lands.

Insect entrepreneurs use almond hulls as feed source for bugs
(Daily Democrat) Ching Lee, Nov. 8
…Maurice Pitesky, a UC Cooperative Extension veterinarian and specialist in poultry health and food-safety epidemiology, conducted an experiment two years ago on pastured layers, feeding up to 20% of the birds' diet with soldier fly larvae “with no change in welfare, egg quality, mortality.” The larvae feed provides methionine, an essential amino acid for poultry, and has “significant potential” to increase poultry production while freeing “more corn and soy calories for humans,” he said, though he warned of two caveats: economics and consistency of manufacturing the feed.
Paradise rebuilds, but fire safety sometimes takes a back seat to economic realities
(LA Times) Laura Newberry, Nov. 8
…“Having this zone right next to a building is pretty important,” said Steve Quarles, a senior scientist with the Institute for Business & Home Safety who studied homes in Paradise after the fire. “No matter what the homeowner does in terms of vegetation management on the property, embers can blow over and ignite that woodpile next to the house.”

Sudden oak death spreading fast, California's coastal forests facing devastation
(San Francisco Chronicle) Peter Fimrite, Nov. 7
…The rate of trees infected almost doubled in 2019 — from 3.5% to 5.9% — and was 10 times higher in some places compared with the 2018 survey, said Matteo Garbelotto, the director of the UC Berkeley Forest Pathology and Mycology Laboratory, which tested leaf samples taken by 422 volunteers.
...“There was a significant increase in infection rates over last year, but that's not totally surprising because we had a lot more rainfall,” Garbelotto said. “But it was a surprise to see them all at once. It's telling us we are entering a different phase of the disease, where the organism isn't really establishing itself in new areas, but is showing itself more when weather conditions are favorable.”
We mapped every wine country fire. They're larger and more destructive than ever
(Los Angeles Times) Priya Krishnakumar, Nov. 7
…Why is this happening? Scientists point to rising temperatures and the effects of Santa Ana and Diablo winds on increasingly dry terrain.
“In a way, climate change is priming the landscape to ignitions,” said Max Moritz, a wildfire specialist at UC Santa Barbara.
…Experts say many of the losses are due to increased development, as more and more homes have been built in areas prone to fire.
“The homes are the fuels,” Moritz said. “We see these burned neighborhoods where there are still shrubs and trees, and it's clear the homes propogated the fire.”

Power shutoffs leave some farmers feeling ‘helpless'
(Ag Alert) Ching Lee, Nov. 6
… "If they've lost cooler capacity or the ability to wash product, not only are they taking a hit on the expense side, but they have less to sell," Placer County sheep rancher Dan Macon said. "That's kind of a double whammy for a number of folks."
… Wineries also are running into this problem, said Anita Oberholster, an enology specialist for University of California Cooperative Extension. Those operating on generators are running low on fuel and can't get it to their wineries, which need power not only to process fruit but to control temperature during the fermentation process. Because yeast can generate a significant amount of heat during fermentation, an inability to control temperature could affect the quality of the wine, she said.
… "People are making the investments they need to make, but it's stuff that's outside the normal course of business, and I think there'll be some financial impacts from that in terms of this season's profitability," he said.
As a UCCE livestock and natural resources advisor, Macon said the outage has prompted him to start sending a survey to farmers in an effort "to catalog resources that are out there and available for sharing in situations like this," whether it's generators, water-hauling capacity or, in the case of fire, the ability to load livestock quickly and safely.

Berkeley — With a body the size of a fist and wings that span more than a foot, the big brown bat must gorge on 6,000 to 8,000 bugs a night to maintain its stature. This mighty appetite can be a boon to farmers battling crop-eating pests.
But few types of bats live on American farms. That's because the current practice of monoculture – dedicating large swathes of land to a single crop – doesn't give the bats many places to land or to nest.
Diversifying working lands – including farmland, rangeland and forests – may be key to preserving biodiversity in the face of climate change, says a new review paper published this week in Science by conservation biologists at the University of California, Berkeley.
Diversification could be as simple as adding trees or hedgerows along the edges of fields, giving animals like birds, bats and insects places to live, or as complex as incorporating a patchwork of fields, orchards, pasture and flowers into a single working farm.
These changes could extend the habitat of critters like bats, but also much larger creatures like bears, elk and other wildlife, outside the boundaries of parks and other protected areas, while creating more sustainable, and potentially more productive, working lands.
“Protected areas are extremely important, but we can't rely on those on their own to prevent the pending sixth mass extinction,” said study co-author Adina Merenlender, a UC Cooperative Extension Specialist in the Department of Environmental Science, Policy and Management at UC Berkeley. “This is even more true in the face of climate change, because species will need to move around to adapt to shifts in temperature and climate.”
A win-win for wildlife and for farms
Maintaining even small pieces of the original landscape – even a single tree– can help conserve the original diversity of species, Merenlender said. Clearing oak woodlands and shrublands to establish large vineyards hits many native species hard. Animals that are well adapted to urban and agricultural areas, such as mockingbirds, house finches and free-tail bats, continue to flourish, while animals that are more sensitive to disturbance, like acorn woodpeckers, orange-crowned warblers and big brown bats, begin to drop away. “If you can leave shrubs, trees and flowering plants, the habitat suitability -- not just for sensitive birds but also for other vertebrates – goes way up,” Merenlender said. This is true not only in California's vineyards, but on working lands around the world.
Incorporating natural vegetation makes the farm more hospitable to more creatures, while reducing the use of environmentally degrading chemicals like herbicides, pesticides and man-made fertilizer.
The ideal farming landscape includes woodland pastures and vegetable plots bumping up against orchards and small fields, said Claire Kremen, a professor in the Department of Environmental Science, Policy and Management. Integrating livestock produces manure which can fertilize the crops, while those same crops produce feed for livestock. Birds and bats provide pest control, and bees boost crop production by pollinating plants.
“It is possible for these working landscapes to support biodiversity but also be productive and profitable,” Kremen said. “And ultimately, this is where we have to go. We just can't keep mining our soils for their fertility and polluting our streams – in the end, this will diminish our capacity to continue producing the food that we need. Instead, we must pay attention to the species, from microbes to mammals, that supply us with critical services, like pollination, pest control and nutrient cycling”
“We have some amazing diversified farms, sustainably managed forests and species-rich rangelands here in California that exemplify working lands for conservation around the world,” Merenlender said. “We are calling for a scaling up of this approach around the world, and to do that we champion community-based action and more supportive polices” Kremen concludes.
