[1] The Dja River almost completely surrounds the reserve and forms a natural boundary which encloses 5,260 km2 (1,300,000 acres).

[1] The Dja Faunal Reserve was created in 1950 and became a World Heritage Site in 1987[1] and it forms an integral part of the dense rain forests that make up the Congo Basin.

It is one of the largest and best-protected reserves within the rainforest zones of Africa with around 90% of its area remaining undisturbed.

The Dja Faunal Reserve is especially notable for the diversity of primate species it protects including white-collared mangabey, mandrill, drill, western lowland gorilla and chimpanzee.

It adjoins onto the Congolese reserve of the Odzala-Kokoua National Park and the Gabonese Minkébé National Park to form the TRIDOMarea, an important zone for the protection of the African rainforest habitat of the Congo basin.
