The West African Primate Conservation Action (WAPCA) aims at the conservation of two highly endangered primate species, the Roloway Monkey (Cercopithecus diana roloway) and the White-naped Mangabey (Cercocebus atys lunulatus), which are endemic to rainforest areas in Ghana and Ivory Coast. The population of Roloway guenons and the White-naped mangabeys serve as prominent “flagship species” for the entire ecosystem of the Upper Guinean Forest with its unique biodiversity of plant and animal species. As examples of their wild relatives these monkeys serve to sensitise zoo visitors to the need for the conservation of biodiversity.

The NGO WAPCA is based on an association of currently 10 European Zoos, conservation organizations and private people. WAPCA implements conservation activities in Ghana. Projects take place at two sites: The Endangered Primate Conservation Centre, a facility which helps to breed the monkeys as part of an internationally coordinated breeding program for endangered species (EEP). This is located in Achimota Forest, Accra.

The second sites are several protected areas in the Western Region of Ghana. The forests of these areas are the natural habitat of the Roloway monkeys and the White-naped Mangabey. These forests are implementation sites for various conservation activities like research, work with Wildlife Division, awareness work in villages and community work on sustainable livelihoods.
