According to this excellent article from The Revelator.
“Earlier this month a series of lightning strikes touched off dozens of fires across California, burning 1.5 million acres, choking cities with smoke and claiming at least six lives. Outside California, large wildfires are burning in Colorado and Oregon, too.
“For people who live near the path of flames or the drifting smoke, wildfire season can be dangerous. And this year’s sudden eruption of multiple blazes is stretching resources thin, as firefighters — already facing restrictions due to the pandemic — work hard to protect lives and property.
“Amidst the barrage of media images of charred homes and sweeping flames, it can be easy to forget that for some native species that live in western forests, wildfires are actually beneficial and necessary, creating valuable habitat and some of the most biodiverse forest ecosystems.
“Burned forests may seem “gone” or “dead” following a severe fire, but if you look closely “there’s an absolute treasure trove of life thriving in there,” says wildlife biologist Monica Bond, principal scientist at the Wild Nature Institute.
“Longhorn beetles and other wood borers are usually the first to arrive after a fire, when they follow the smell of smoke to feast on recently burned trees, still rich in sapwood but lacking the ability to secrete the sticky, toxic resins that would normally fend off the insects. Black-backed woodpeckers often arrive next, feeding on beetle larvae and carving out nest cavities in the trees that will provide habitat for other birds after the woodpeckers move on.
“As flowers and shrubs begin to grow back, that draws more insects and birds. Certain wildflowers, like fire poppies, emerge only from the ashes, and wildfires can create bumper crops of morels, a group of beautiful, delicious mushrooms.
“Mammals, meanwhile, arrive in waves, looking for different types of food. “You have seeds that have been exposed by the fire that small mammals are eating,” says Bond. That entices larger predators. Studies have also shown that burned forests are beneficial for numerous bat species.
“Then, as long as you don’t cut down the standing dead trees, you can have species like spotted owls returning, too,” she says. The snags, as the dead trees are called, also provide shelter for a range of forest life, including bluebirds, flying squirrels and Pacific fishers.
“Even the fallen dead trees become an important component, cycling their nutrients back into the soil.
“It’s a process that’s been repeated across western forests for millennia, including the Pacific Northwest, Canada’s boreal forests, the Rocky Mountains and the Sierra Nevada. All have historically burned with a mix of fire types, including severe wildfires, says Bond.”
