The North and South American prairies and the Asian and Australian steppes are grassland habitats that, unlike the savanna, undergo greater changes in season and temperature: hot in the summer and cold in the winter. Also called temperate grasslands, these habitats have evolved over thousands of years to withstand wind, storms, torrential rainfall, fire, and grazing by large animals. A prairie usually has taller grasses than a steppe; some of the dry, short-grass prairie of North America's Great Plains is also called a steppe.
