Science Says: Climate change, people stoke California fires

Seth Borenstein, AP NEWS

If you want to build a fire, you need three things: Ignition, fuel and oxygen. But wildfire in California is a much more complex people-stoked witch’s brew.

The state burns regularly because of fierce autumn winds, invasive grasses that act as kindling, fire-happy native shrubs and trees, frequent drought punctuated by spurts of downpours, a century of fire suppression, people moving closer to the wild, homes that burn easily, people starting fires accidentally or on purpose — and most of all climate change.

“California has a really flammable ecosystem,” said University of Colorado fire scientist Jennifer Balch. “People are living in flammable places, providing ignition, starting the wildfires against a backdrop of a warming climate that is making wildfires worse.”

Trying to manage California’s wildfires is like trying to hold back a tidal wave, said Columbia University fire scientist A. Park Williams: “Big fires are kind of inevitable in California.”

And it’s getting worse, fast. Area burned by wildfire in California increased more than fivefold since 1972, from a five-year average of 236 square miles (611 square kilometers) a year to 1,394 square miles (3,610 square kilometers) a year according to a 2019 study by Williams, Balch and others.

Dozens of studies in recent years have linked bigger wildfires in America to global warming from the burning of coal, oil and gas, especially because it dries plants and makes them more flammable.

“ Fuel moisture drives the fire business,” said University of Alberta fire scientist Mike Flannigan. “Fuel moisture is being influenced by climate change.”

In California, a Mediterranean climate sets up ideal conditions for fire then is worsened by climate change, said University of California, Merced, fire scientist LeRoy Westerling, who has had his home threatened twice in the last few years.

The benefits of headwater forest management

Lori Pottinger, PUBLIC POLICY INSTITUTE OF CALIFORNIA

The health of California’s headwater forests is in decline, leaving them increasingly vulnerable to major wildfires and droughts that threaten the many benefits they provide. Even in the midst of the current COVID-19 pandemic, California must plan for the upcoming fire season, and continue work to reduce its risks. At a virtual event last week, PPIC researcher Henry McCann described how improved management can make Sierra forests more resilient and avoid major wildfire-related disasters, and summarized the findings of a new report that identifies the benefits and beneficiaries of such management practices.

“Expanding on the pace and scale of long-term forest stewardship is going to be a heavy lift for private and public entities,” said McCann. “Developing a clear sense of the benefits and beneficiaries of improving forest health is key to motivating long-term stewardship and identifying the partners to support it.”

An expert panel moderated by study coauthor and UC cooperative extension specialist Van Butsic discussed how this translates into practice.

What does the science tell us about managing California’s wildfire- and drought-prone forests? “It tells us there are opportunities for win-win scenarios, where a forest treatment designed to reduce fire risk will likely also have other benefits—for carbon storage, biodiversity, wildlife habitat, water output,” said panelist Carmen Tubbesing, a PhD candidate in forest ecosystems and fire sciences at UC Berkeley.

Group gets $1 million for Sonoma Valley fire prevention efforts

Kevin Fixler, THE PRESS DEMOCRAT

Protected Wildlands Map

Cal Fire has awarded more than $1.7 million for wildfire prevention in Sonoma County, with the bulk of the money going toward a coalition working to reduce fire risk on public lands in Sonoma Valley.

The Sonoma Valley Wildlands Collaborative received more than $1 million, allowing it to conduct controlled burns, clear brush and thin forests. The newly formed group of private and public agencies oversees 18,000 acres of fire-prone areas along Highway 12 that include Hood Mountain Regional Park and Sugarloaf Ridge and Trione-Annadel state parks, which were burned in the Tubbs and Nuns fires.

“The areas that we’re talking about have a long history of fire,” said Tony Nelson, longtime Sonoma Valley program manager for the Sonoma Land Trust, which is part of the collaborative. “It has burned in the past and we know it will burn again. The vegetation is not going to stop growing, so we need to not stop managing our natural systems with fire, as well as (need to) maintain safety.”

The collaborative also includes state and regional parks, the Sonoma County Agricultural Preservation and Open Space District, Audubon Canyon Ranch and the Sonoma Mountain Ranch Preservation Foundation. The group is a product of discussions predating the 2017 wildfires that raced over the Mayacamas Mountains and left behind scorched ridgelines, charred trees and ashen soil. The firestorm renewed conversations on how to prevent large-scale blazes.

Judge: PG&E put profits over wildfire safety

A U.S. judge berated Pacific Gas & Electric Corp. on Wednesday, accusing the nation’s largest utility of enriching shareholders instead of clearing trees that can fall on its power lines and start fires and making “excuses” to avoid turning off electricity when fire risk is high.

Judge William Alsup in San Francisco did not immediately order PG&E to take any of the dramatic measures he has proposed to try to stop more wildfires.

But he warned that he was not ruling out at least some new requirements on the company if it did not come up with a plan to “solve” the problem of catastrophic wildfires in California.

“To my mind, there’s a very clear-cut pattern here: that PG&E is starting these fires,” Alsup said. “What do we do? Does the judge just turn a blind eye and say, ‘PG&E continue your business as usual. Kill more people by starting more fires.'”

Alsup is overseeing a criminal conviction against PG&E on pipeline safety charges stemming from a 2010 gas line explosion in the San Francisco Bay Area that killed eight people and destroyed 38 homes.

He proposed earlier this month as part of PG&E’s probation that it remove or trim all trees that could fall onto its power lines in high-wind conditions and shut off power when fire is a risk regardless of the inconvenience to customers or loss of profit.

Wildfires: Managing the risk

Dan Farber, LEGAL PLANET

How can we limit the spread of wildfires and save people and property?

Wildfires are already a serious problem, and climate change will only make the problem worse, as I’ve discussed in my two prior posts. Reducing carbon emissions can help keep the problem from growing, but we need to deal with the risks we’re already facing. That is going to require a portfolio of risk management strategies. We need to ramp up all of them.
Land Use Controls.

There are increasing numbers of people moving into the wild-land urban interface (WUI).The USDA’s report on the WUI says that 3.8 million people live in that zone in California alone. Nationally, a million homes were added to the WUI just in the decade from 1990-2000. That simply isn’t sustainable.

Human activities increase the risk of fire from sparks or burns, and homes are typically highly flammable and help fires spread more quickly. Better land use controls could limit development in high risk areas. Easier said than done, however, given development pressures. According to a 2013 study, ” land use planning for wildfire has yet to gain traction in practice, particularly in the United States. However, fire history has been used to help define land zoning for fire planning in Italy, and bushfire hazard maps are integrated into planning policy in Victoria, Australia.” By 2016, however, Headwaters Economics was reporting on five Western US cities that were taking advantage of at least some land use tools to reduce fire risks, though none seem to have imposed outright bans on development in high-risk areas.

Buyouts may be a fallback in extreme situations. Building codes can also help — for instance, by requiring fire-resistant roofs on new houses. Liability rules for fires have to be carefully considered. Making utilities liable for fires can cause them to take greater precautions, but the prospect of compensation could also encourage people to live in unsafe areas. On the other hand, fire insurance costs can send an important price signal about the risks of WUI property ownership, as some Californians are already beginning to experience.
Land Management.

Gov. Brown’s wildfire plan will only make things worse

Chad Hanson and Char Miller, THE LOS ANGELES TIMES

Responding to the tragic losses of homes and lives in wildland fires in California over the past year, Gov. Jerry Brown announced a “major offensive” against fire, in the form of a “Forest Carbon Plan.” The governor proposes to use $254 million of taxpayer money to double logging levels in California’s forests — to “at least” 500,000 acres a year — and to achieve it, he wants to reduce environmental protections.

Although the governor’s May 10 proposal is ostensibly designed to protect human communities from forest fires and to mitigate climate change, it ignores and misrepresents current science. The Forest Carbon Plan will exacerbate climate change while doing little to protect communities from fire.

Most of the devastating impacts to communities from recent California wildland fires have occurred in grasslands, chaparral and oak woodlands — not in forests. This includes the October 2017 fires in northern California, and the December 2017 Thomas fire and Creek fire in southern California. Claiming to protect towns from fire by increasing logging in remote forests is a bit like proposing the construction of a sea wall in the Mojave Desert to protect coastal populations from rising oceans.

Moreover, reducing environmental protections in forests, and increasing logging, as Brown proposes, does not tend to curb fire behavior — in fact, it typically does the opposite. This is because logging reduces the cooling shade of the forest canopy, creating hotter and drier conditions, and removes tree trunks, which don’t burn readily, while leaving behind “slash debris” — kindling-like branches and treetops

Op-Ed: A stark reminder of the importance of controlled burning

Jim Doerksen,  THE PRESS DEMOCRAT

My wife and I live on a beautiful LandPaths property on St. Helena Road in northeast Sonoma County. For more than 50 years, we have managed the property for timber production of about 50 percent Douglas firs and 50 percent redwoods and includes many native heritage specimens of hardwood trees. We have managed this forest to be as fire resistant as possible by pruning lower branches, thinning the trees, and burning brush piles.

One very important issue that seems to have been overlooked is the part played by the Bay Area Air Quality Management District. This is the agency that notifies the public when it is a “spare the air day.” The rules and regulations are daunting and virtually impossible to adhere to, especially in forest management.

This is an excerpt from an e-mail I sent to the air quality district in June 2016 in which we expressed our concern that air quality district standards were having an adverse effect on forestry cleanup “and will probably result in a mass uncontrollable fire” in Sonoma County.

“Not enough is being done about cleaning up all the brush and dying and fallen trees. To make matters worse, we have had a huge outbreak of bark beetle and sudden oak death. To add insult to injury, PG&E, in its great wisdom, has cut thousands of trees under the transmission lines and has left them to decay or burn.”

The analysis post-fire from CalFire agrees with our opinion as being correct. The fires have done a thorough job of cleaning up the forest floor, but frequent fires are necessary to prevent build-up of tree debris, weeds and brush.
