Central Africa > Democratic Republic of the Congo > Okapi Wildlife Reserve
Summary
- Eastern chimpanzees (Pan troglodytes schweinfurthii) are present in Okapi Wildlife Reserve.
- It has been estimated that 8,802 individuals occur in the site.
- The chimpanzee population trend is unknown.
- The site has a total size of 13,700 km².
- Armed groups involved in illegal mining, logging and hunting are the most concerning threat to chimpanzees and other wildlife in the Okapi Wildlife Reserve.
- Conservation activities at the site include anti-poaching patrols.
Site characteristics
Established in 1992, the Okapi Wildlife Reserve occupies about one-fifth of the Ituri forest in the Democratic Republic of the Congo (Okapi Conservation Project). The reserve was declared a UNESCO World Heritage Site in 1996, and it is also an Important Bird Area, with nearly 400 bird species recorded (BirdLife International 2020). The site is one of the largest blocks of intact forest remaining in the Congo Basin. The forest is important for the Mbuti and Efé pygmies, who live here as hunter-gatherers (BirdLife International 2020; UNESCO). The reserve is famous for being home to the largest population of the endemic okapi, Okapia johnstoni (BirdLife International 2020; UNESCO). The reserve supports other mammals of global conservation, including eastern chimpanzees, forest elephants, water chevrotains, aquatic genets, bongos, Hamlyn's monkeys, and mountain monkeys (BirdLife International 2020). The site is also notably rich in butterfly species (BirdLife International 2020).

Threats
The presence of armed militia involved in illegal mining, logging and hunting is one of the most concerning threats to the Okapi Wildlife Reserve. In 2012, armed rebel groups brutally attacked the headquarters of the reserve, killing six people and 14 captive okapis (Dasgupta 2019). Immigration is also a serious threat, as the RN4 road, which bisects the southern part of the reserve was rehabilitated, allowing easy access to pristine forests (IUCN).

Conservation activities
In 2019 an agreement was reached to manage the Okapi Wildlife Reserve between Wildlife Conservation Society (WCS) and the Government’s Nature Conservation Agency, ICCN (WCS).

| Civil unrest | IUCN |
Research activities
A research project has been based at Epulu since the early 1980s and has been supported since 1986 by the Wildlife Conservation Society. Besides conducting the first study of Okapi in the wild, this project has included long-term studies of natural and selectively-logged forest and research into the socio-economic impact of human migration (BirdLife International 2020).
