A study was conducted on the exploitation of natural resources and the sustainable management of the vegetation of the Ngaoundéré cliff. Structured and semi-structured interviews were conducted with 350 people, 50 per village. The data obtained were supplemented by direct field observations. Data analysis using Excel, STATGRAPHICS Plus 5.0 and XLSTAT showed that farmers (88.93%), breeders (80.07%), craftsmen (49.29%), hunters (28.93%) are the main operators of the resources of the cliff. The products exploited are involved in food (55.28%), medicine (30.51%), crafts (53.34%), and trade (43.54%). The most commonly used species in the cliff are Borassus aethiopum (100%) and Mangifera indica (100%) in the diet, Isoberlinia doka (68.17%) as firewood, Khaya senegalensis (63.50%) in the medicine, Piliostigma thonningii (100%) for artisanal use and edible NTFP (40, 63%) in the trade. Faced with this exploitation of the biodiversity of the vegetation of the cliff, a forest management plan has been developed in a spirit of community management based on the participatory approach which invites all actors and social partners to take part in the decision making based on consensus between the conservative trend and the local population.
