UC fire scientists provide invaluable expertise to media during fire tragedies

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.”
