A national grassland is an area of protected and managed federal lands in the United States authorized by Title III of the Bankhead–Jones Farm Tenant Act of 1937 and managed by the United States Forest Service. For administrative purposes, they are essentially identical to national forests, except that grasslands are areas primarily consisting of prairie. Like national forests, national grasslands may be open for hunting, grazing, mineral extraction, recreation and other uses. Various national grasslands are typically administered in conjunction with nearby national forests.
