The tropical savanna usually surrounds the region of the tropical rainforest. The vegetation in the savanna consists of tall grasses. You can also find occasional trees wherever tree roots can reach underground water. Birds, insects, and snakes are also common in this biome.
Savanna soils are of better quality than rainforest soils.
But the savanna has less rainfall, and plants need water. Large regions of savanna surround the rainforest regions of the Amazon of South America and the Zaire area of Africa. The Everglades of south Florida are another example of tropical savanna. Savanna regions do not support large populations of humans. Miami, Florida is built in a savanna biome.
