- The site is designated as a Ramsar Site.
Site characteristics
Conkouati-Douli National Park (CDNP) was established in 1999, replacing the Conkouati Wildlife Reserve existing since 1980. CDNP is situated in the southwest corner of the Republic of Congo, bordering Gabon's Mayumba National Park to the north. Together, Mayumba National Park and CDNP form the Conkouati-Mayumba landscape, characterised by coastal lowland forest that extends into higher altitude forest in the mountains to the east, and descends to the inland savanna plain (Tutin et al. 2005). As a result of CDNP's broad habitat diversity, the park is the most biodiverse in Congo. In addition to chimpanzees and gorillas, CDNP is home to many threatened species, including forest elephants, mandrills, and forest buffalo. Marine species, such as manatees, turtles, dolphins and whales, are also found at the site. The coastline of the park, which comprises 35% of the country's coastline, is an important site for sea turtle nesting, particularly for Leatherback and Olive Ridley turtles (WCS; BirdLife International 2020). The site is also an Important Bird Area, with at least 288 species present (BirdLife International 2020). CDNP is also designated as a Ramsar Site and is registered on the indicative list of UNESCO World Heritage (Parcs de Noé).

Threats
Lack of hunting controls and law enforcement combined with high demand for bushmeat in urban markets threaten the ape population at CDNP (IUCN 2014).
