Site characteristics
Monts Birougou National Park was established in 2002. The park comprises forests, swamps, savanna, valleys, and mountainous zones up to 900 m asl, which are the source of the Nyanga and Ngounié rivers and their main tributaries (Ramsar 2007). About 20 different primate species are found in the site, including the endangered western lowland gorilla and chimpanzee (Ramsar 2007). Portions of the park have been designated as a Ramsar site since 2007.
