In 1997, Rebecca Kormos conducted a transect survey around the village Moyerai which is located to the North of the site Koumbia and concluded that chimpanzees were present in relatively high densities (Ham 1998). In 2010, the [http://www.wildchimps.org Wild Chimpanzee Foundation] did a transect survey in Koumbia (survey area was bordered by the Sentha river and Guinea-Bissau in the North and the Kongo river and the Boké-Gaoual in the South) and estimated that 296 individuals (CI: 164-532) occurred in the area (WCF 2012).

More recently, the mining company [https://www.amcbauxite.com Alliance Mining Commodities] started developing a Bauxit mining site west of Koumbia. There are plans to build a road to the mining site and a port at the river Rio Nuñez (Alliance Mining Commodities 2018).

The European funded AGIR project (Programme Régional d’Appui à la Gestion Intégrée des Ressources Naturelles des Bassins du Niger et de la Gambie) identified 42 conservation zones at this site with the aim of establishing community-based forest management (WCF 2012). AGIR was implemented until 2005 and also encompassed an environmental awareness raising scheme (WCF 2012).
