Natural values and features include the ongoing ecological and evolutionary processes in a mostly intact forest landscape at a very large scale. Numerous and diverse habitats such as tropical forests comprised of deciduous and evergreen species, a great diversity of wetland types, including swamp forests and periodically flooded forests and many types of forest clearings of major conservation importance continue to be connected at a landscape level. This mosaic of ecosystems harbours viable populations of complete faunal and floral assemblages, including top predators and rare and endangered species, such as Forest Elephants, Gorillas, Chimpanzees, and several antelope species, such as the Sitatunga and the emblematic Bongo.
Maintaining the ecological values of the property will not only depend on law enforcement but eventually both on the standards of commercial resource extraction in the buffer zone and the acceptance and support of parks by the local and indigenous communities in the surrounding landscape.
