Grassland

Region in which the climate is dry for long periods of the summer, and freezes in the winter. Grasslands are characterized by grasses and other erect herbs, usually without trees or shrubs. Grasslands occur in the dry temperate interiors of continents, and first appeared in the Miocene.

A community of grasses and trees in a particular area is also a grassland in which grasses predominate trees are either altogether absent or present in relatively small number.
