Biome found in both temperate and tropical regions and characterized by periodic drought, flat or slightly rolling terrain, and large grazers that feed off the lush grasses.

Lands on which the vegetation is dominated by grasses, grasslike plants, or forbs. Non-forest land is classed as grassland if herbaceous vegetation constitutes at least 80 percent of the canopy cover, excluding tress. Lands that are not now grasslands but were originally or could become grasslands through natural succession may be classified as potential natural grasslands.
