These remarkable forest-dwelling primates face severe habitat loss in Central African forests.
Mandrills and drills are among the most striking primates. Both species are threatened by bushmeat hunting and deforestation in Cameroon, Gabon, and nearby countries. Mandrills live in large multi-male groups with social complexity that makes welfare assessment nuanced. Drill populations have declined severely. Conservation programs focused on habitat protection and bushmeat trade reduction address both welfare and population survival.
