Primate species endemic to West Africa, west of Sassandra River

Not less than 13 species of primates are found in the TGKS landscape, of which 8 are endemic to West Africa. In addition, several of these species, or their subspecies, have a so-called «sassandrian» distribution, being restricted to the west of the Sassandra River in Côte d’Ivoire. These include the endangered Western chimpanzee (Pan troglodytes verus), the Sooty mangabey (Cercocebus atys), and the Diana monkey (Cercopithecus diana)
