National Forests are federally owned and managed by the United States Forest Service, part of the United States Department of Agriculture. Unlike designated Wilderness and National Parks, these areas allow for commercial use, including timber harvesting, livestock grazing, water, wildlife, and recreation.
Across the country, National Forests add up to 193 million acres of wildlands, host 170 million visits each year, and sustain nearly 223,000 jobs in gateway communities. In Montana alone, which boasts 10 National Forests comprising 19.39 million acres, 3.4 million acres within National Forests are congressionally designated Wilderness areas. While they are open to industry, these forests support about 61.3 percent of Montana’s annual water supply.
