• Central chimpanzees (Pan troglodytes troglodytes) and western lowland gorillas (Gorilla gorilla gorilla) are present in Zone Humide d'Ebogo.
• The population sizes are unknown.
• The population trends are unknown.
• The site has a total size of 30.97 km².
• Forest loss and forest degradation due to wood harvesting, agriculture and collection of non-timber forest products are some of the known threats in the site.
• Conservation activities are unknown.
• The site was designated a Ramsar site in 2012.

Site characteristics

The site is located about 40 km south of Yaoundé, the capital city of Cameroon. The area supports several IUCN Red-Listed plant species including the African Pearwood (Baillonella toxisperma), Sapele (Entandrophragma cylindricum) and Ebony (Diospyros crassiflora). It also supports nationally important animal species such as the Nile Monitor (Varanus niloticus) and the African Python (Python sebae) as well as over 100 waterbird species. The temporarily flooded marshes serve as food and breeding ground for waterbirds. It was designated as a Ramsar site in 2012. The forest also supports a rich diversity of non-timber forest products important to the local population both as a source of food and as a cultural heritage (Ramsar 2012). The area is surrounded by the Mbalyamo Forest Reserve.
