Grasslands are vast ecosystems characterized by grasses, wildflowers, and herbs, and occupy almost a quarter of the earth's surface. These diverse habitats go by many names in different regions of the world. In North America, they are called prairies, while in Africa, they are known as savannas, and in Australia, they're referred to as rangelands. Steppes are the term for this biotype in Eurasia, while in South America, they go by the name of llanos. Pampas is another name for grasslands located in southern South America.
