Grasslands

Grasslands are dominated by a rich mix of grasses and forbs (non-grass plants); herbaceous and non-woody plants. They have low precipitation rates and are maintained by fire, which suppresses tree saplings.  This biome becomes prominent during the Miocene epoch (23-5 Mya) due to a cooling, drying climate on Earth. Grasslands have very fertile soil; therefore, they have been extensively converted to agriculture. When the soils of grasslands are compromised, these biomes frequently become deserts.  

Grasslands are sometimes also called a prairie, meadow, pasture, range, plain, steppe, pampas, sward, llano, or the veldt
