Chacma baboons (Papio hamadryas ursinus) are a widespread and successful primate species in southern Africa (Estes 1992, Rowe 1996). The ability to live in many habitats, under challenging environmental conditions, is a major reason for their success (Altmann 1998). In South Africa, the rapid increase of urbanization and decreasing number of unprotected natural areas has caused many species, including baboons, to become scattered and isolated. This is the situation facing a population of chacma baboons in the Suikerbosrand Nature Reserve, a small mountainous grassland reserve situated in Gauteng Province.
Suikerbosrand Nature Reserve comprises ideal habitat for baboons with a range of different habitats such as open grassland, Acacia savannah, mixed shrub land and denser wooded areas. Challenges facing baboons include seasonal fluctuations and spatial changes in food availability with regard to habitat availability. Problems arise when a population grows too large for small areas of protected natural habitats. When the foraging needs imposed by baboons on natural resources are not sustainable, it is likely that baboons will look to adjacent human resources, such as farming or urban environments, to meet energy demands.
