Rangeland means a land cover or use category with a climax or potential plant cover composed principally of native grasses, grass-like plants, forbs, or shrubs suitable for grazing and browsing, and introduced forage species that are managed like rangeland. Rangeland includes lands re-vegetated naturally or artificially when routine management of that vegetation is accomplished mainly through manipulation of grazing. This term includes areas where introduced hardy and persistent grasses are planted and such practices as deferred grazing, burning, chaining, and rotational grazing are used with little or no chemicals or fertilizer being applied. Grasslands, savannas, many wetlands, some deserts, and tundra are considered to be rangeland. Certain communities of low forbs and shrubs, such as mesquite, chaparral, mountain shrub, and pinyon juniper are also included as rangeland.
