Grassland

Grassland is one of several types of terrestrial biomes, where grasses form the predominant vegetation, usually mixed with herbs and sometimes with shrubs, but usually without trees. Grassland dotted with trees is called savanna.

Grasslands usually get 10 - 30 inches of rainfall annually. Fires, natural and human-caused, are important in the maintenance of many grasslands.

Grasslands may occur naturally or as the result of human activity. Grasslands created and maintained by human activity are called anthropogenic grasslands. Hunting peoples around the world often set regular fires to maintain and extend grasslands, and prevent fire-intolerant trees and shrubs from taking hold. The tallgrass prairies in the American Midwest may have been extended eastward into Illinois, Indiana, and Ohio by human agency. Other anthropogenic grasslands include pasturelands, where forest or shrublands were cleared to create lands for intensive grazing.

Flooded grasslands are grasslands that are flooded seasonally or year-round, like the Everglades of Florida or the Pantanal of Bolivia and Paraguay. They are classified with flooded savannas as the flooded grasslands and savannas biome, which occurs mostly in the tropics and subtropics.
