In 2020, 9,000 fires scorched more than 4 million acres of California, a record-breaking year, reported Alejandra Borunda in National Geographic. Fires burned through homes and oak forests, grasslands and pines — and also through patches of giant sequoias and coast redwoods, respectively the most massive and the tallest trees on earth.
Giant sequoias are not the oldest living trees, but some have been growing in Sierra Nevada forests for more than 3,200 years. They are found in 68 groves on the Sierra's western flank. The state's redwood forests grow in a narrow strip along the coast of Northern California and Southern Oregon.
The 2020 fires burned through about 16,000 acres of sequoia groves, about a third of their total area. In redwood forests of the Santa Cruz Mountains, 40,000 acres burned.
But because redwoods are well-adapted to fire, they'll likely recover pretty quickly, said Scott Stephens, a UC Berkeley fire scientist. “In some ways, this fire could make redwoods more dominant in the landscape," he said, because other trees — like the hardwoods or Douglas firs that crowded the local forests — died outright in the burns.
However, scientists are concerned one cause of the fires, climate change, could have additional impacts on these natural treasures.
Since the mid-1800s, temperatures in the western U.S. have increased by 1.6 degrees Fahrenheit. Fog banks are fading in coast redwood territory, and snows are less consistent in the Sierras. The changes leave redwoods and sequoias without their preferred climate conditions.
The most responsible thing to do now, Stephens said, is to “take the opportunity that has been handed to us,” and make a plan to go back in and burn again—soon, within the next few years.
UC Cooperative Extension forestry advisor Lenya Quinn-Davidson agrees that California must manage fire to help the trees survive. Tree-ring records show that humans have influenced the fire regime for better and worse as long as they've been in these forests.
“The empowering message there is, human management can actually override the effects of climate in a fire contest,” Quinn-Davidson said. “It's not just a climate story. We can't just throw in the towel, feel overwhelmed, and tell ourselves these trees are done for. That's not true!”

On a crisp and clear morning late last year, around 20 volunteer firefighters, landowners and community members gathered on a plot of land outside of the small rural community of Kneeland in Humboldt County. They listened intently to detailed instructions on how to safely burn 20 acres of private property that gradually rises on a hill before them. The volunteers gathered to learn how to successfully undertake a prescribed burn. It was all part of the ongoing education and training being conducted by Humboldt County's Prescribed Burn Association – the first of its kind west of the Rockies.
Lenya Quinn-Davidson and Jeffery Stackhouse, who both work for the UC Cooperative Extension in Humboldt County, developed the program in 2017 and have seen it steadily grow ever since. The association is comprised of landowners, nonprofits, volunteer firefighters and other community members who work together to carry out prescribed burns on private land. Until the association was created, most landowners and community members had lacked access to prescribed burn information and training.
“Fire is a natural part of California's landscape. Prescribed fire is a way for us to bring fire back to the landscape as a natural process under controlled conditions. We can choose the weather, we can choose how it's going to burn,” says Quinn-Davidson. “Private landowners have largely been left out of the fire picture and we realize that is a big part of the problem.”
The goal of the prescribed burn on that October day was to eliminate an invasive type of tree that was overtaking the grassy hill and restore the land to a state where native oaks can thrive once again. The property owners are receiving the same training as the volunteer firefighters on hand. Beyond eliminating invasive species, the association is utilizing prescribed burns to reduce fuels to prevent future wildfires, as well as restore wildlife habitat. But most importantly, the training and education empowers landowners and others to reconnect with fire as a management tool.
Since the Association was created, it has burned more than 1,000 acres in Humboldt County. The association has also been able to build a strong working relationship with CalFIRE, which also conducts prescribed burns on private lands in Humboldt.
Will Emerson is an assistant fire chief for the volunteer Bell Springs Fire Department in northern Mendocino County. He and his three colleagues made the 2.5-hour trip to participate in the prescribed burn training session in Humboldt County. He sees the trainings as a “really great experience” for volunteer fire departments, some of which have new trainees who have never worked a fire before.
“It's excellent training for them — just to get comfortable working with fire,” Emerson says.
The concept of a prescribed burn association is catching on. Quinn-Davidson and Stackhouse have presented the Humboldt County model to numerous counties around the state, and new associations are cropping up around California.
“We use our program to train people, to inspire people, to empower people,” Quinn-Davidson says.
The value of Humboldt County's Prescribed Burn Association goes beyond the training it provides. Quinn-Davidson and Stackhouse view the association as a “community cooperative,” bringing together groups that have traditionally been at odds. At any training session you may find volunteers from the ranching or timber industry, environmentalists or cannabis growers.
“Instead of being on opposite sides of an issue, people are gaining understanding for the other side,” Stackhouse says. “It has opened the door for real, honest communication between different groups that otherwise would not be happening. Having people work together who have been on different sides of the community really is amazing.”
Quinn-Davidson agrees. “We are building community and we are using fire as this positive, synergistic thing,” she concludes. “And I feel so positive about it.”
The CSAC Challenge Awards were created in the early 1990s to recognize county innovation and best practices. Humboldt County's Prescribed Burn Association is a recipient of a 2019 CSAC Challenge Award – one of only 18 Challenge Awards presented statewide out of 284 entries.

As California grappled with a record-breaking heatwave last week and 236 wildfires, officials are bracing for the worst, reported Maanvi Singh in the Guardian.
The fires have been mostly fueled by grass and brush that came up during the state's especially wet winter and mild spring, according to a CAL FIRE official. UC Cooperative Extension fire advisor Lenya Quinn-Davidson said California's annual wildfire season is growing longer – beginning earlier in the spring and stretching later in the fall.
“It's not unusual for us to see this many small fires in June,” she said. “But 50 years ago, so many fires this early on – plus these extreme, high temperatures in June – would have been abnormal.”
It is difficult to predict how bad the rest of this fire season will be based on the number of fires so far, said UCLA climate scientist Daniel Swain.
"Our worst fire years aren't necessarily the years that we've had the highest number of fires,” he noted. “All it takes is one – one huge, destructive fire to ruin the whole year."

Historically, fire fighting was a male-dominated field. With broader diversity needed, women are seizing the opportunity, reported The Nature Conservancy.
TNC ran a feature on its website about a prescribed fire on its Disney Wildness Preserve in Florida staffed and managed by an all-women crew.
"Everybody was here to work, and communication went well," said Jana Mott, the day's burn boss and TNC's northern Florida stewardship project coordinator. "It was like a well-oiled machine. There was a high level of professionalism all around. It felt like just another day of doing business on the fireline."
The article also quoted UC Cooperative Extension fire scienctist Lenya Quinn-Davidson. She is director of the Northern California Prescribed Fire Council. Quinn-Davidson helped plan and lead the Women-in-Fire Prescribed Fire Training Exchange (WTREX) in Tallahassee, as well as two previous WTREX.
The field of wildland fire has for too long been “so conventional, so static—not only operationally, but also culturally,” Quinn Davidson said. “We see now that it's time for that to change. We need more perspectives, more ideas, more innovation—more creative discomfort. And we need to create space for women and men of different backgrounds to have a voice and contribute to this evolution.”

The humble rake has been in the spotlight in recent weeks, and its role as a forest management tool ridiculed and scorned. However, most fire professionals believe rakes are a necessary part of saving California's forests.
Those who are familiar with fire are undoubtedly familiar with the McLeod, which is a standard firefighting tool and … it is essentially a rake (one side is a rake with coarse tines and the other side has a flat sharpened hoe). The McLeod was created in 1905 by a U.S. Forest Service ranger who wanted a single tool that could rake fire lines (with the teeth) and cut branches and roots (with the sharpened hoe edge). The McCleod is used to scrape fuels off of a fire line, preventing fire spread. The use of hand tools like the McLeod continues to be one of the standard ways that wildfires are stopped (although often aided by the rake's bigger and more powerful cousin: the bulldozer).
While the McLeod is a fire-fighting tool, it is also an essential fire-managing tool. When conducting controlled burns (i.e., purposeful fire), the fire is contained within desired areas by diligent raking with McLeods and other hand tools. These tools are necessary for conducting controlled burns.
While it isn't feasible to reduce fire risk by raking the forest with hand tools, if you hold a drip torch in the other hand, you could get the work done.
A drip torch consists of a canister for holding fuel that comes out of a spout (with a loop to prevent fire from entering the fuel canister) and a wick from which flaming fuel is dropped to the ground when the wick is ignited. The drip torch is the most common tool for lighting prescribed burns, which can be used to remove excess fuel buildup in the forest.
In a forest setting, these two tools — the rake and the torch — must be used together. Without a rake, the fire is not easily contained. And without a drip torch, the fuel that was raked cannot burn. Of course, prescribed burns rely on a number of other pre-specified factors (the prescription), including wind, temperature and humidity.
Using fire in a controlled manner drastically reduces the impacts of wildfire in a forest. Typically flames are kept low and most or all of the trees survive the fire, while much of the dead material on the forest floor (the “fuel”) is consumed. This reduces the risk of the forest burning at high severity in the future, thereby protecting nearby homes and towns. It also reintroduces fire as an important ecosystem process, which improves the health and biodiversity of forests and maintains the ecosystem services they provide, including wildlife habitat, water filtration and carbon sequestration.
Use of a rake and a drip torch together could make a great difference for reducing the impacts of wildfire in California and the West. The National Interagency Fire Center reported that during 2017, only half a million acres were treated with prescribed fire in the West, while 7.4 million acres (almost 15 times more) burned in wildfires. In the Southeastern U.S., where there is a long-standing tradition of prescribed burning, only 2 million acres burned in wildfires while over 5.5 million were burned using prescribed fire.
This was not always the case. Use of prescribed fire, or ‘light burning,' was once common in California until it was outlawed by federal and state policy in 1924. Although the merits of expanding its use are widely known and appreciated, it has been very difficult to do because of concerns about air quality, liability and lack of skilled burners. One of the biggest constraints is that we have very few people who have experience with ‘good fire' and very few qualified people who know how to safely burn.
As foresters and educators for the University of California Cooperative Extension, we are working to expand the use of prescribed fire on private forest and grasslands in California. Central to our efforts are educational events that give people an opportunity to experience prescribed fire first-hand. In the last two years, we have hosted workshops throughout northern California, and many of our workshops have included a live-fire component where landowners and other community members can try their hand at prescribed burning, under the direction and guidance of more experienced burners.
Our efforts in California are inspired by approaches in other parts of the country, including “Learn and Burn” events in the Southeast, prescribed burn associations in the Great Plains, and prescribed fire training exchanges (TREXs), an innovative training model developed by The Nature Conservancy's Fire Learning Network. All of these efforts have a focus on reconnecting people with fire, and they give participants the skills and experience needed to put fire back in the management toolbox.
We hope that by empowering people to pick up the drip torch (and the rake) on their own properties, we can help them educe the risk of wildfire and improve the health of their forest and range lands. There is no time to waste.
