Situated in the north-western Congo Basin, where Cameron, Central African Republic and Congo meet. The site encompasses three contiguous national parks totaling 750,000ha. Much of the site is unaffected by human activity and features a wide range of humid tropical forest ecosystems with rich flora and fauna, including Nile crocodiles and Goliath tigerfish, a large predator.
Forest clearings support herbaceous species. Sangha is home to considerable populations of forest Elephants, critically endangered western lowland Gorilla and endangered Chimpanzee. The site's environment has preserved the continuation of ecological and evolutionary processes on a huge scale and great biodiversity, including many endangered animal species.
