Temperate grasslands are similar to tropical savanna, but are found in regions with relatively cold winter temperatures. This biome is found in South Africa, Hungary, Argentina, Uraguay, Russia, and North America. Large vertebrate grazers are the most conspicuous, such as bison, antelopes and wild horses. However the most intense grazing of grasslands takes place below ground by invertebrates, who consume up to four times as much as all above ground herbivores. This biome remains grassland, and is not taken over by woody shrubs and trees, because of seasonal drought, occasional fires, and grazing by large mammals. The soil of grassland is the deepest and most fertile in the world. |
