Bigcone Douglas-fir is an evergreen conifer native to the mountains of Southern California. Repeated wildfires and drought are threatening the species' existence in its native range, reported Bettina Boxall in the Los Angeles Times.
The reporter visited a Santa Barbara County site peppered with tall, dead trees where UC Cooperative Extension fire specialist Max Moritz is studying the species' fate.
"You don't see anything," he said. "It has a fairly depressing quality to it, given the mortality and no regeneration."
The area was burned by the Zaca Fire 11 years ago, something the fire-resistant conifer can generally withstand. Moritz and research assistant Ryan Salladay found evidence that the trees survived the fire, but then died sometime later. They are trying to determine what did them in by recording the aspect of the slope, collecting tree core samples, measuring the water stress in living trees, looking for wildfire impacts, and checking for seedlings.
“The drought-following-fire issue is a total reshuffling of what might come back or survive,” Moritz said.
U.S President Donald Trump criticized forest management in California and threatened to cut off federal emergency funding this week, eliciting confusion and condemnation, reported Ryan Bort in Rolling Stone.
The International Association of Fire Fighters released a statement calling Trump's move "disgraceful." "While our president is tweeting on the sidelines in DC, our fellow Americans 3,000 miles to the west are mourning loved ones, entire communities have been wiped off the map and thousands of people are still trying to figure out where they are going to call home."
The reporter wrote that the president is fixated on the state's role in causing forest fires, but the federal government owns the majority of forested land in California. Moreover, the devastating Camp and Woolsey fires of 2018 were not forest fires; they were wildland-urban interface fires, according to UC Cooperative Extension wildfire specialist Max Moritz.
"In these environments, as we've seen, it can be the homes themselves that are burning and spreading fire to other nearby homes. Managing vegetation can thus have relatively little effect on fire spread," Moritz said.
The federal government shutdown itself is having a major impact on wildfire prevention, reported Ezra David Romero on Capital Public Radio.
Typically, forest managers analyze their budgets and plan for the next fire season during the winter. But the government shutdown has suspended these efforts because the U.S. Forest Service - which has been furloughed since Dec. 22 - plays a big role.
Crews in Redwood National Park are “just sitting on their hands,” according to UC Cooperative Extension fire advisor Lenya Quinn-Davidson in Humboldt County, because they can't work on federal land during the shutdown. She said that workers were “excited to do more” on the heels of the state's worst fire season in history. “This is just taking the wind out of their sails."
The shutdown is also causing challenges for UCCE forestry specialist Bill Stewart. He's working on collaboration between the UC system and the Forest Service to streamline the cost of preventing wildfires. But the shutdown is making the five-year project, which has end-of-January deadlines, difficult to accomplish.
“Everything has come to a total stop,” Stewart said. “They are not even allowed to answer their emails. If this continues it may be hard to restart for this next season.”

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.”

…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

…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

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.
Can California Improve Forest Management And Prevent Wildfires Without Going Broke?
(Capital Public Radio) Ezra Romero, Dec. 13

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.”

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.”

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."

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.”
