States are responsible for responding to wildfires that begin on nonfederal (state, local, and private) lands, except for lands protectedby federal agencies under cooperative agreements. The federal government is responsible forresponding to wildfires that begin on federal lands. The Forest Service (FS)-within the U.S. Department of Agriculture-carries out wildfire management andresponse across the 193 million acres of the National Forest System. The Department of the Interior (DOI) manages wildfire response for more than 400 million acres ofnationalparks, wildlife refuges andpreserves, other public lands, and Indianres ervations. Wildfire statistics help to illustrate past U.S. wildfire activity. Nationwide data compiled by the National Interagency Fire Center (NIFC) indicate that the number of annual wildfires is variable but has decreased slightly over the last 30 years and that the number of acres burned annually, while also variable, generally has increased (see Figure 1). Every year since 2000, an average of71,300 wildfires burned an average of 6.9 million acres. This figuie is more than double the average annual acreage burned in the 1990s (3.3 million acres), although a greater number of fires occurred annually in the 1990s (78,600 on average). Table I.

Note: Data reflect wild land fires and acres burned nationwide, including wild land fires on federal and nonfederal lands. Over the p as t 10 years, there were an average of 64,100 wildfires annually and an average of6.8 million acres burned annually. In 2019, 50,477 wildfires burned 4.7 million acres nationwide, below the annual average for both statistics. More thanhalf of the acreage burned in 2019 was in Alaska (2.5 million acres), which was the only area that experienced significantly above-average wildfire activity for the year. The 2015 fire season was thelargest onrecoid, with 10.1 million acres burned (see Figure 2); more than half of these acres were in Alaska (5.1 million acres). As ofDecember4, 2020, nearly 53,000 wildfires have burned over 9.5 million acres this year. Figure 2.

The number of fires and acreage burned are indicators of the annual level of wildfire activity, but they may be misleading, since many fires may occur in large, relatively undeveloped areas, with very little impact to human development or communities. Acreage burned also does not indicate the severity of the wildfire or the degree of impact to the forest, soils, or any other ecologicaleffects. Updated December 4,2020
