This trans-boundary complex, including the Rio Campo Reserve (335 km²) in Equatorial Guinea and the adjacent Campo Ma’an National Park (2,640 km²) in Cameroon, is situated in the Atlantic Coastal Forest zone.
It contains a remarkable biodiversity, including a signiﬁcant population of gorillas, chimpanzees and mandrills, and a rich ﬂoral diversity including several endemic species.
The principal threats in the area stem from commercial hunting and habitat destruction. At present, the Park is surrounded by agro-forestry zones and logging concessions. Of principal concern is the project for a hydroelectric dam on its periphery.
In spite of the existence of a minimal management presence inside the national park, protection efforts and collaborative reduced-impact projects with developers are urgently needed.
