Thinning dense stands of trees across millions of acres of U.S. forestlands is a central piece of the Biden administration’s $50 billion plan to protect against deadly firestorms that have been exploding across western states
Western wildfires have become more volatile as climate change dries forests already thick with vegetation from years of intensive fire suppression. And the window for controlled burns is shrinking.
Across the Rockies, piles of slash and trees cleared to reduce fire hazards span some 100,000 acres , waiting to be burned once the right amount of snow is on the ground. Sometimes there's too much, making the piles inaccessible.
2020 was the worst wildfire season on record in Colorado, where summers and falls also have been warmer and drier, said Assistant State Climatologist Becky Bolinger. It's"a completely different ball game in terms of wildfires,” she said. Putting off pile burning carries consequences, too. Until the piles are gone, forest managers won't begin another kind of controlled fire called broadcast burning, which consumes vegetation within stands previously thinned with chainsaws and other equipment.
