From the Document: "Wildfires are unplanned and unwanted fires. Wildfires can have some beneficial impacts on an ecosystem, but they often threaten homes and communities, forcing the evacuation of thousands of people. Wildfires are sometimes caused by lightning strikes and may also occur when a prescribed burn escapes control or through other human activities (deliberate or accidental). From 2010 through 2019, wildfires burned 6.8 million acres annually on average in the United States. In 2019, more than 50,000 wildfires burned 4.7 million acres, more than half of which were in Alaska. In 2018, wildfires destroyed nearly 25,800 structures nationwide. More than 70% (18,130) of the structures were residences. Approximately 94% (17,130) of the structures were in California. Congress and other stakeholders have considered options for federal support and assistance to address wildfire suppression during a fire, post-wildfire recovery, and land management activities to reduce the risk of future catastrophic wildfires."
