Tropical savanna and grazers in Kenya. The tropical savanna landscape is partially maintained by per

Most tropical savannas occur north and south of tropical dry forests within 10° to 20° of the equator. In Africa south of the Sahara Desert, tropical savannas extend from the west to the east coasts, cut a north–south swath across the east African highlands, and reappear in south-central Africa (fig. 2.29). In South America, tropical savannas occur in south-central Brazil and cover a great deal of Venezuela and Columbia. Tropical savannas are also the natural vegetation of much of northern Australia in the region just south of the tropical dry forest. The savanna is the natural vegetation of an area in southern Asia just east of the Indus River in eastern Pakistan and northwestern India.
