[1] This site has an area of 3,500 km2 on the border with Gabon's Batéké Plateau National Park.

Since 2004, the Wildlife Conservation Society (WCS) and the Ministry of Forestry Economy have carried out detailed biological and socio-economic surveys in and around the proposed Ogooué-Leketi National Park (OLNP), to evaluate the conservation potential of this area, and to define the appropriate boundaries and benefits of the new protected area.

Following the closure of the three logging concessions that overlapped the proposed protected area, Ogooué-Leketi has officially been declared Congo's fifth National Park.

[2] The OLNP lies in a unique landscape, dominated by vast rolling savannahs in the east, with green ribbons of gallery forest linking up to a larger rainforest block to the north and west.

[2] The park is home to forest gorillas, chimpanzees, forest elephants, forest buffalo, red river hog, several species of monkey including the mandrill, and other threatened species such as Grimm's (or bush) duiker, side-striped jackal, three species of bustard, Congo Moorchat (Traquet-fourmilier du Congo), Brazza's Martin (Hirondelle de Brazza), and a probable new species of cisticola.
