How are grasslands classified?
Grasslands may be classified into steppes and savannahs. In the steppes the prevailing vegetation is grass, as in the pampas of South America and in the prairies of North America. The fauna is mainly formed by herbivores, like rodents and ungulates. The savannahs present small trees, for example in the Brazilian cerrado or the African savannahs. The fauna is diverse; in the Brazilian cerrado there are animals like ostriches, lizards, armadillos, jaguars, etc., and many types of insects; the African savannahs are the home of large herbivores and carnivores, like zebras, giraffes, antelopes, lions and leopards.
