Equatorial Africa contains several very diverse ecosystems including multi-strata tropical forest, dry deciduous forest, woodland, mosaic grassland forest, savannah woodland, savannah, and desert.
Chimpanzees have adapted to a variety of these habitats, including mosaic grassland and tropical moist forests and savannah woodlands. They can be found at altitudes ranging from sea level to elevations of almost 3000 meters.
Africa’s tropical zones are drier than those of Asia and America, with only a few regions receiving more than 2500 millimeters of rainfall per year. Many of Africa’s tropical forests lie close to the equator and experience two rainy and two dry seasons per year. It is thought that the tropical regions of Africa were fragmented by dry forests and woodlands prior to human clearing activities, a possible explanation for the extremely adaptive nature of chimpanzees.
