Large expanses of land in the tropics do not receive enough rainfall to support extensive tree cover. The Tropical and Subtropical Grasslands, Savannas, and Shrublands are characterized by rainfall levels between 90-150 centimetres per year. However, there may be great variability in soil moisture ... и Humans have affected the savanna biome in many ways. The increased use of the savanna by humans has caused degradation of this biome. Extinction of animals in this biome is caused by humans releasing foreign species into the savanna. Humans have killed predators, built dwellings, and cleared land to be able to farm.
