Site characteristics

Bakossi National Park is located in western Cameroon, to the south of the Banyang-Mbo Wildlife Sanctuary and covers an area of 29,320 ha. The altitude in the park ranges from 300m to 1895m a.s.l., giving rise to three main vegetation types: sub-montane forest, Atlantic forest of the North West type with semi-deciduous elements, and the Atlantic Biafran forest rich in Caesalpiniaceae. This accounts for the huge floral variety of the area and a high level of endemism, and a corresponding high diversity of fauna species (Enukwa et al. 2022). The site is a hotspot for many primate species, including the Drill (Mandrillus leucophaeus), one of the most endangered primate species in the world, and the Chimpanzee (Pan troglodytes). Other primates include Preuss’s red colobus, Red-eared guenon, Preuss’s guenon, Putty-nosed monkey, Mona monkey and other important mammals like Blue duikers, Red river hog, Red-fronted duiker, Black-fronted duikers, Sitatunga, and Long tail pangolin (WWF). The Bakossi forests support several small streams, cascading waterfalls and deep pools, and the Mungo River which flows through the park. Along the way, thousands of people far beyond the site depend on the river for their livelihoods through activities such as fishing, sand extraction, and logs and food transportation (WWF).
