National forests in SoCal reopen on Thursday. Why climate change keeps closing them

“Safety is paramount, especially in these days of high summer,” artist and author Obi Kaufmann says about the recent forest closures. Art by Obi Kaufmann.

Four national forests in Southern California open back up on Thursday: Los Padres, Angeles, San Bernardino and Cleveland.

On August 30, citing high fire danger and limited resources, U.S. Forest Service officials shut down all the national forests in California, which cover approximately 20 million acres. 

Those forests were shut down last summer too, for the same reasons.

Should we expect massive, weeks-long shutdowns of forests each year?

“It's definitely a tool that we haven't used in the past,” says Zach Behrens, public affairs officer of the San Bernardino National Forest. “Is it something that's going to be continued to be used? I think that's something we're gonna be looking at.”

There’s a tug-of-war between maintaining safety and granting people access to their public lands. And due to climate change exacerbating fire danger, safety is winning. 

It comes down to available resources, says Behrens. When the Dixie and Caldor Fires were at their peak, firefighters and staff from Southern California rushed north to assist. That meant there were not enough personnel in Southern California.

“We don't want to put people in a position where they're in the forest, [and] they're trying to escape a fire that's maybe growing bigger than it normally would because we didn't have as many firefighters,” says Behrens.

Obi Kaufmann, naturalist and author of “The California Field Atlas” series, agrees that forest closures are becoming increasingly necessary.

“[In] August 2020, a third of all of the land area that burned in California in the past 90 years did so in 90 days. So this is going to become a policy element where safety is paramount, especially in these days of high summer,” he says.

Behrens and Kaufmann agree that a level of forest management, like forest thinning and prescribed burns, is necessary to prevent fires from getting so large. But Kaufmann notes that selective thinning can often come in the guise of commercial harvest, and an approach that works in the forests of Southern California may not work in the forests of Northern California.

“It's a totally different arboreal composition, and when you're talking about habitat, ecosystem, and aridity, it's all very complex and nuanced.”

Kaufmann will be hosting a virtual event with Wade Crowfoot, California's Secretary of Natural Resources, on September 30. On a camping trip in the Sierra Buttes, the pair will discuss wildfires, water shortage, climate change, and an action plan to be better stewards of California's biodiversity.
