San Diego County officials want to approve construction of about 10,000 homes in areas largely labeled by CAL FIRE as posing a "very-high" fire hazard, reported Joshua Emerson Smith in the San Diego Union Tribune.
County supervisors said the subdivisions are badly needed and developers have laid out exhaustive fire-prevention blueprints. However, UC Cooperative Extension fire specialist Max Moritz said these building codes and other rules don't take into account whether a particular project should be built there at all.
“There are 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 said. “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.”
The recent outbreak in California of two devastating fires - the Woolsey Fire in Ventura and Los Angeles counties and the Camp Fire in Butte County - are being covered extensively by the news media. UC Agriculture and Natural Resources fire scientists provide a valuable service by making themselves available to share their expertise during these tragedies. Below are a sampling of recent fire stories with comments from UC ANR sources.
Why Wildfires Are Burning So Hot And Moving So Fast
(NPR) Kirk Siegler
…One recent study predicted several million homes built in the West are at immediate risk. Susie Kocher is a forester with the University of California's Cooperative Extension service here in the Sierra.
“We haven't caught up, and to retrofit our existing housing stock to fend off embers is a long-term, expensive proposition.”
These wind-driven fires often carry air and embers that land on a roof or get sucked into a vent long after the main wall of flames has passed through. In fact, that's when most homes actually burn in wildfires.
“Even areas like Paradise that have been inhabited for 140 years as more vulnerable than they used to be. And that's not because there's new development but because there's a new climate around the old community.”
And that brings us to one of the biggest factors: climate change. Droughts are longer and more severe. The snow is melting quicker. The fire seasons are longer if not year-round.
As wildfires grow deadlier, officials search for solutions
(Associated Press) Matthew Brown and Ellen Knickmeyer, Nov. 14
…"There are ... so many ways that can go wrong, in the warning, the modes of getting the message out, the confusion ... the traffic jams," said Max Moritz, a wildfire specialist with the University of California Cooperative Extension program.
As deadly urban wildfires become more common, officials should also consider establishing "local retreat zones, local safety zones" in communities where residents can ride out the deadly firestorms if escape seems impossible, Moritz said.
… In the mid-20th century, California ranchers burned hundreds of thousands of acres annually to manage their lands, said Lenya Quinn-Davidson, director of the Northern California Prescribed Fire Council.
That was phased out in the 1980s after California's fire management agency stepped in to take over the burns, and by the last decade, the amount of acreage being treated had dropped to less than 10,000 acres annually, Quinn-Davidson said.
Former agricultural land that rings many towns in the state became overgrown, even as housing developments pushed deeper into those rural areas. That was the situation in the Northern California town of Redding leading up to a fire that began in July and destroyed more than 1,000 homes. It was blamed for eight deaths.
"You get these growing cities pushing out - housing developments going right up into brush and wooded areas. One ignition on a bad day, and all that is threatened," Quinn-Davidson said. "These fires are tragic, and they're telling us this is urgent. We can't sit on our hands."
Trump and Brown stir up rhetoric on wildfires but overlook pressing problems
(LA Times) Bettina Boxall, Nov. 14
… Similarly, UC Berkeley fire scientist Scott Stephens said that although climate change is playing a role in wildfire growth, he worries that a focus on global warming can leave the public thinking that “there's really nothing to be done.”
In fact, he said, “Communities could still be better prepared.”
How Does California's Wildlife Cope With Massive Wildfires?
(Atlas Obscura) Anna Kusmer, Nov. 13
While many animals are indeed displaced by wildfires, it's important to note that fire is not wholly bad for landscapes in an ecological sense. In fact, many California ecosystems rely on fire to thrive. “Fire in the human sense can often be catastrophic, but it's not necessarily the same for animals,” says Greg Giusti, a retired University of California researcher and an expert on the relationship between wildfires and wildlife. He says California wildlife have evolved to respond to fires, and can even sometimes benefit from the disruption. “It's harsh out there, but you know these animals have evolved to survive in that hostile environment.”
There are a variety to survival tactics that California wildlife will use, says Giusti. For example, birds are easily able to fly away and are usually not impacted as long as fires don't occur during the spring when they are nesting and raising their offspring.

California Must Better Prepare For The Inevitability Of Future Fires (reprint of The Conversation originally published in August)
(Pacific Standard) Max Moritz, Naomi Tague & Sarah Anderson, Nov 13
Wildfire has been an integral part of California ecosystems for centuries. Now, however, nearly a third of homes in California are in wildland urban interface areas where houses intermingling with wildlands and fire is a natural phenomenon. Just as Californians must live with earthquake risk, they must live with wildfires.
Forest management debate
(KTVU) Heather Holmes, Nov. 12
In a live interview, Bill Stewart, UC Cooperative Extension specialist at UC Berkeley, said,
“It was actually on the private land that we saw better performance in terms of being able to put out the fire quicker and a lot less smoke being produced. There is a package of vegetation management and fire suppression on private lands that have proved to be more effective than what's being used on federal land.
“What we found is about half the difference comes from the private land managers do more aggressive timber harvesting and some of that profit they spend to reduce the shrubs and fuels that are on the ground because they have that cashflow. They're protecting their long-term assets. The other half is CALFIRE is much more aggressive when it comes to fire suppression in forests or shrublands.
Trump's Misleading Claims About California's Fire ‘Mismanagement'
(New York Times) Kendra Pierre-Louis, Nov. 12
…Mr. Trump is suggesting that forest management played a role, but California's current wildfires aren't forest fires.
“These fires aren't even in forests,” said Max Moritz, a wildfire specialist at the University of California, Santa Barbara.
…“We have vulnerable housing stock already out there on the landscape. These are structures that were often built to building codes from earlier decades and they're not as fire resistant as they could be,” Dr. Moritz said. “This issue of where and how we built our homes has left us very exposed to home losses and fatalities like these.”
California's year-round wildfire threat: Why aren't communities doing more?
(SF Chronicle) Peter Fimrite and Kurtis Alexander Nov. 10,
…“To have a president come out and say it's all because of forest management is ridiculous. It completely ignores the dynamic of what's going on around us.” said LeRoy Westerling, a climate and fire scientist at UC Merced, who blamed the increasing number of fires on rising temperatures and more variable precipitation, leading to longer spells of dry weather.
…“It's like a tragic replay of last year, with strong winds in both Northern California and Southern California blowing fire,” said Max Moritz, a wildfire specialist at the Bren School at UC Santa Barbara, recalling the 2017 Wine Country fires and the Thomas Fire, which burned through Ventura and Santa Barbara counties in December.
…“We had a lot of discussion after the fires last year about the liability issue with utilities, but it's interesting to see what didn't happen,” Moritz said. “Nobody has talked about mapping neighborhoods and homes in fire-prone areas like they do in flood plain hazard zones, engineering resilience into communities, or building a little smarter.”
…Everybody agrees the situation is dire. Fire officials blame shorter winters, hotter temperatures and drier vegetation, but very little is being done to improve the situation, said Scott Stevens, a professor of fire science at UC Berkeley.
“There is an under-appreciation of fire risk in a lot of communities,” Stevens said. “It feels like we can do better at allowing local communities to access information, reduce their vulnerability and understand their vulnerability a little bit more.”
Stevens urged the creation of cooperative programs at his and other universities that would allow local government officials to collaborate with fire experts on safety planning.
California's most destructive wildfire should not have come as a surprise
(LA Times) Bettina Boxall and Paige St. John
…“We have these Santa Ana-like events happening in places that are appearing to catch people by surprise,” said Max Moritz, a cooperative extension wildfire specialist at UC Santa Barbara's Bren School. “But they shouldn't be catching people by surprise.”
“These are areas that have burned before,” he said. “And if we were to go back and do the wind mapping, we would find that at some intervals, these areas are prone to these north and northeasterly Santa Ana-like events.”
… “We have all kinds of tools to help us do this smarter, to build in a more sustainable way and to co-exist with fire,” he said. “But everybody throws up their hands and says, ‘Oh, all land-use planning is local. You can't tell people that they can't build there.' And the conversation stops right there.”
Enormous wildfires spark scramble to improve fire models
(Nature) Jeff Tollefson, Aug. 31
…“Something is definitely different, and it raises questions about how much we really know,” says Max Moritz, a fire scientist at the University of California, Santa Barbara.
… The problem, Moritz says, is that most of the fire models in use today are based on data from the past two or three decades. But it seems that fire behaviour might be shifting in response to climate faster than anybody expected, and that makes it increasingly problematic to extrapolate from past trends, he adds.

Deadly poultry ailment, Newcastle disease, reaches Ventura County
(Ventura County Star), Aug. 29
Maurice Pitesky, a veterinarian and University of California extension specialist in the School of Veterinary Medicine at UC Davis, said one of the challenges in keeping a lid on the disease is the continued popularity of raising backyard chickens.
“While people have the best intentions, unfortunately a lack of biosecurity practices in people's backyards is one of the contributing factors of the disease spreading,” Pitesky said.
The longtime head of the UFW is stepping down. His replacement will be the first woman to lead the union

Expert Views: Managing Wildfires to Protect Water Resources
(Water Deeply) Lindsay Abrams, Aug. 28
Van Butsic, cooperative extension specialist at the University of California, Berkeley:
"Managing forest and wildfires to benefit water resources is difficult because there are trade-offs between short-term costs and long-term benefits. In the short term, wildfires can lead to increased erosion and sedimentation in streams and reservoirs. This contributes to lost revenue for downstream power generators and at times even requires water to be treated before it is potable."
Can Angelenos and Coyotes Coexist?
(LA Magazine) Henry Cherry, Aug. 27
…Intrigued by the animals, I stumbled across Coyote Cacher, an interactive website operated by University of California's Dr. Niamh Quinn. A native of Ireland, Quinn has been studying coyotes for about four years. “There are no coyotes in Ireland, but when I came here there was the need for coyote research in Southern California,” Quinn says. “There is a need for professional extension to the cities and the police departments, the people that never managed coyotes before but all of a sudden find themselves needing to do so.”
Why homes are lost to wildfire — is yours as safe as it could be?

Limiting suburban sprawl can ease the devastation of wildfires
(Mother Nature Network) Matt Hickman, Aug. 27
…But there's a bigger issue at hand. Max Moritz, a wildfire specialist with the University of California's Division of Agriculture & Natural Resources, relays to Martin Kuz of the Christian Science Monitor that inaction from state lawmakers who are reluctant to lead the charge in restricting development in vulnerable areas is only worsening the situation. Presently, local officials, developers and homeowners face few limitations when building in fire-prone wild land urban interfaces. Moritz refers to this as a “political will problem.”

The Social Costs of Living in Wildfire-Prone Areas
(East Bay Express) Alastair Bland, Aug. 21
…"But that's so politically contentious — it's a line politicians walk up to but turn away from," said William Stewart, a UC Berkeley forestry and wildfire specialist.
… “People seem to have short memories," said Sabrina Drill, a natural resources advisor for the UC Cooperative Extension, a statewide off-campus division of the university system that focuses on agriculture and natural resources. "I think people might think twice about building a home where there had just been a fire, but people seem to forget after about three years."
… Van Butsic, a UC Berkeley researcher who studies forestry and land use, has closely studied this. In a paper now under review for publication, he and scientist Anu Kramer, from the University of Wisconsin, describe an alarming trend of building homes in known fire-risk areas.
"We studied 30 of the largest fires since 1970," he said. On average, they found that 20 years after an inhabited area burns, not only were most of the destroyed homes rebuilt but many new homes were added — about twice as many homes in total as there were at the time of the burn.
… In 2016, researcher Susan Kocher spent nine months on sabbatical in Provence, the arid region of southern France that resembles much of inland California. Here, Kocher — the Central Sierra Natural Resources Advisor for the UC Cooperative Extension — compared building patterns in high-fire risk parts of California and France.
"In California we often say, 'We should be able to tell people they can't build here,'" said Kocher, whose research, coauthored with Butsic, was published in March of 2017 in the journal Land. "In France, they just tell people they can't build somewhere."

‘Batnadoes' Can Protect California's Crops
(Atlas Obscura) Anne Ewbank, Aug. 16
… He's likely right, according to Rachael Long, a farm advisor with the UC Cooperative Extension in the Sacramento Valley. She's researched for decades how bats can help farmers control pests. “Armyworms are always a big problem in rice production,” she says. “Bats are predators, of armyworms, cutworms, and other pests.” Bats' nocturnal feasts prevent adult moths from laying eggs that will hatch into hungry, rice-eating caterpillars, and, Long says, their impact cannot be overstated. When pest populations get out of control, “it can be really devastating.”

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

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.

…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.
California Groundwater Law Means Big Changes Above Ground, Too

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