Land on which the natural potential (climax) plant cover is principally native grasses, grasslike plants, and shrubs. It includes natural grasslands, savannahs, certain shrub and grasslike lands, most deserts, tundra, alpine communities, coastal marshlands, and wet meadows. It also includes lands that are re-vegetated naturally or artificially and are managed like native vegetation. The United States has 406 million acres of rangeland on non-federal lands and about 257 million acres on federal lands. The non-federal rangelands are about 30% of all non-federal rural lands, according to the 1992 National Resources Inventory. The federal lands are managed by the BLM (approximately 167 million acres) and the Forest Service (approximately 95 million acres).
