UCCE experts provide scientific fire information to media
The raging fires sparked during August have raised the visibility of UC fire scientists, who provide critical information to state and national media. Below are a sampling of stories and comments offered by UC Cooperative Extension experts:
Forest management needed
“When we started suppressing fires 100 years ago all the time, we actually allowed a huge buildup of fuels and debris,” said UC Cooperative Extension forest advisor Susie Kocher, who is based in the Lake Tahoe region.
She is an advocate for requiring residents to clean up the extra fuel — grasses, trees, shrubs and clutter — around their homes, making them fire ready, and for more prescribed burns.
“There's a need for more frequent, low-severity fire across the landscape, so that we wouldn't have quite so much explosion in the burning in the fields that we have currently,” Kocher said.
In August, the state and federal government agreed to clean up 1 million acres by 2025, with practices such as prescribed burns. Part of that agreement also included a commitment to create a 20-year plan by next year to prioritize areas for forest-thinning. But even this plan is sliver of what's needed to protect California from devastating future wildfires.
“I think it's a good indication they're paying attention now and that we're moving in the right direction,” said Michael Jones a UC Cooperative Extension forestry advisor in Mendocino, Lake and Sonoma counties. “My hope is that once we start with a million, then it's really easy to scale up to multiple millions.”

“There are things that we can and should be doing to address the fire problem and fire risk in California, and to get ahead of it, and to make ourselves more resilient,” said Lenya Quinn-Davidson, a fire advisor with the University of California Cooperative Extension and director of the Northern California Prescribed Fire Council.
Quinn-Davidson said she was encouraged when California Gov. Gavin Newsom and U.S. Forest Service officials announced an agreement this month on a joint strategy to reduce wildfire risks.
“We need more coordination and more collaboration among all of the different groups who work on these issues,” Quinn-Davidson said. “The number one thing we need is more coordinated vision around what fire is going to look like in California, how people can live with fire.”

What's at stake
“Every part of California is receptive to wildfire,” said Yana Valachovic, a UC Cooperative Extension forestry advisor on the North Coast. “Especially in a year like this, when we had a pretty dry winter and spring, so a lot of the state is in drought conditions.”

Fires are getting worse
"They are certainly getting worse over time," said Susan Kocher, a forestry advisor at the University of California-Cooperative Extension Central Sierra. "We burned fewer acres in wildfires in 2019 than 2018, but overall, yes, the trend is progressing to burning more and more acres at high severity over time and affecting more people through evacuations and damages to homes and communities."
Yana Valachovic, a forest advisor and county director at University of California Cooperative Extension–Humboldt and Del Norte counties, said that 100 years of fire suppression is catching up to the state as well. Valachovic said before California was settled by white pioneers around the gold rush in the 1850s, Native Americans frequently used fire as a tool —for example, to clean out an infestation of bugs in acorns.
"Fire can be really important for stimulating biodiversity and creating more food sources," Valachovic said. "After years of suppressing those fires, now we get an ignition, whether human-caused or lightning-caused or power lines down, and you have an accumulation of materials that have accumulated over various time periods, but the quantity of fuel is substantially greater than it was historically."

Firefighting priorities
“At the statewide level, we do get into this mode where we start wondering where the biggest loss is going to be, what's the highest priority, and that is where the resources are going to go,” said Lenya Quinn-Davidson, a fire specialist with the UC Cooperative Extension.

Take action
Q: Beyond widely accepted reasons for wildfires growing in size, severity, and frequency, why hasn't California made more progress in slowing the trend?
Lenya Quinn-Davidson: Our fire management and our land management haven't kept pace with the scientific understanding we have of fire in California. There's this fear of active land management – prescribed burning, thinning – that sometimes gets in the way of us making good choices. If we're not protecting the resources we care about and we're not taking action, then we will continue to lose them to big fires.
Bill Stewart: Many of the fires around the greater Bay Area are in areas that didn't burn 30 years ago because they were cattle ranches. They had cattle on them, and that helped reduce fuels. Now those areas have turned into parks or 5- and 10-acre residential lots. So much development has been about what's aesthetically pleasing, so we've ended up with a landscape that, during hot and dry seasons, there's a lot more fuel and it becomes a much riskier situation.
Q: The era of megafires in California has been decades in the making. How can public agencies begin to counter that over the next few years?
Quinn-Davidson: We need to create a more robust and sustainable fire workforce. Right now, they're so beat down at the end of fire season – especially as fire season is getting longer in California – that there's basically no capacity the rest of the year to do any of the proactive stuff we need to be doing. So we need to create more jobs, and those jobs need to be dedicated to fire management and land management.

Historical fire suppression
“We have put out fires for 100 years. Now we are paying the price,” said Scott Stephens, a professor of fire science at UC Berkeley. “It will take a while to make these forests healthy again. But it's absolutely possible.”
Stephens, the UC fire scientist, estimates that before the Gold Rush, roughly 4.5 million acres a year in California burned. By the 1950s and 1960s, that was down to about 250,000 acres a year. In recent years, it has approached 2 million acres a year.

Limited firefighting resources
At the statewide level, we do get into this mode where we start wondering where the biggest loss is going to be, what's the highest priority, and that is where the resources are going to go,” said Lenya Quinn-Davidson, a fire expert with the University of California Cooperative Extension.

Smoke impact on fresh produce
According to a 2018 preliminary UC Cooperative Extension Sonoma study, smoke from 2017 fires had little impact on local Sonoma County produce.
Based on preliminary findings, "...produce safety was not significantly affected by the fires and may be mitigated by washing produce."
