Grassland
In many other parts of the world, the grasslands have little rain or long dry periods. There are few trees because of the low rainfall. Thorny trees called acacias are one of a handful of trees that are able to grow in some African savannas. Wildfires are common and destroy trees. The animals also prevent trees from growing as they eat the tender sprouts before they can develop into grown trees. Elephants are known to tear down grown-up trees and feed on their leaves, making trees even more scarce.
