GRASSLANDS
Grasslands have many names—prairies in North America, Asian steppes, savannahs and veldts in Africa, Australian rangelands, and pampas, llanos and cerrados in South America. But they are all places where there is too little rain for trees to grow in great numbers. Instead, these lands are covered in grasses and grass-like plants that have growing points close to the soil and can keep on growing even after being nibbled on by animals. These grasses can support high densities of grazing animals, such as zebra, antelope and bison. Temperate grasslands have hot summers and cold winters. Summer temperatures can be well over 100 degrees Fahrenheit, while winter temperatures can be as low as -40 degrees Fahrenheit. Because of the open landscape and the widely spaced trees, grasslands are home to large herds of grazing mammals such as the zebra and bison. Annual rainfall in the grasslands is between 10 to 30 inches, there is a seasonal drought every year.
