Savanna is a mixed woodland-grassland environment characterized by trees spread sufficiently wide apart so that the canopy does not close. The tree density may be high and regularly spaced, or trees may be widely scattered. The prevalence of large herbivorous creatures and seasonal periods of fire ensure that there is little ground scrub, but fast-growing grasses may reach to six feet. These areas are found in the central parts of continents, away from the coasts, between 5° and 15° from either side of the equator.
The savanna climate has a distinctive wet season from May to October, with rainfall equalling that of the Equatorial rainforest; the dry season is desert-like, lasting from November to April. This cycle is determined by the location of the Trade Winds, which delineates a parkland savanna, with many trees, from a dry savanna, with scattered trees, or a parched savanna where trees occur hardly at all upon a sandy, scrub-covered soil. These degrees of savanna form as belts along the south edge of the Sahara desert in Africa, from south to north:
