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.
Montana has 10 National Forests comprising 19.39 million acres across the state. While they are open to industry, the National Forests also contain most of the designated Wilderness Areas and Wilderness Study Areas.
