Green Mountain National Forest is a national forest located in Vermont, a temperate broadleaf and mixed forest typical of the New England/Acadian forests ecoregion. The forest supports a variety of wildlife, including beaver, moose, coyote, black bear, white-tailed deer, wild turkey, and ruffed grouse. The forest, being situated in Vermont's Green Mountains, has been referred to as the granite backbone of the state.
Established in 1932 due to uncontrolled overlogging, fire and flooding, the forest originally consisted of 102,100 acres; however, only 1,842 acres were federally owned, while the remaining 100,258 acres within the national forest boundary were not federally owned or administered. As of 2011, the forest boundaries included 821,040 acres, of which 399,151 acres were federally owned and administered. GMNF is one of only two national forest areas in New England, the other area being the White Mountain National Forest in New Hampshire.
In descending order of land area, GMNF is located in parts of Bennington, Addison, Rutland, Windham, Windsor, and Washington counties.
