BILLINGS, Mont. (AP) — The Biden administration says it will significantly expand efforts to stave off catastrophic wildfires that have been torching areas of the U.S. West by more aggressively thinning forests around “hot spots” where nature and neighborhoods collide. Officials have crafted a $50 billion plan to more than double the use of controlled fires and logging to reduce vegetation that feeds fires. Agriculture Secretary Tom Vilsack tells The Associated Press the work will focus on regions where out-of-control blazes wiped out neighborhoods, including California’s Sierra Nevada mountains and Colorado’s Rocky Mountains. Climate change is heating and drying out the West. That makes wildfires more intense even as people increasingly move into fire-prone areas.
