Savanna
Global Locations and Climate
Savannas are characterized by hot, dry seasons with scattered trees. They are found in Africa, Madagascar, Australia, South America, India, and the Myanmar-Thailand region of Southeast Asia. The average temperature is 64 degrees F, with 30 to 50 inches of rainfall a year. There are two different seasons in the savanna; wet and dry. During the wet season, it rains continuously for long periods of time. In the dry season, the hot sun bakes the ground, which becomes hard and can only bear certain kinds of plants.
In the picture above, the Savannas are depicted in yellow.
Dominant Plant and Animal Species
Most animals that live in the savanna migrate due to the different seasons.
The savannas of Africa hold the world's greatest species of hoofed animals, or ungulates.
Most herbavorous animals are herd animals.
There is generally a cover of perennial grasses, 3 to 6 feet tall at maturity, that spreads across the savanna. Other plant life mostly consists of tall grasses and the occasional tree.
Environmental Issues
-Overgrazing is one of the main problems that savannas face. The land gradually turns into a desert when there is not enough plant life to sustain water in the ground.
