Ethnobotany of Some Selected Tree Species in Southwest Cameroon

An ethnobotanical investigation was carried out in 12 villages in Manyu and Fako Divisions, South-western Cameroon to determine economic potentials and priorities of eight non-timber forest products (NTFPs) tree species and three tree crops. Gross farmer income in Manyu was found to be 30% from NTFPs and 70% from established tree crops, while in Fako it was 15% and 85% respectively. The yield of tree crops (160-1047 kg/farmer/year) was higher than NTFPs (0.3-273kg/farmer/year). Some 21 diseases were treated using 10 tree species. Farmers assigned highest priority for NTFPs to Irvingia gabonensis (Aubry-Lecomte ex O’Rorke) Baill., Ricinodendron heudelotii (Baill.) Heckel, Dacryodes edulis (G. Don) H.J.Lam, Irvingia wombolu Vermoesen, Cola lepidota K. Schum. and Garcinia kola Heckel for their cultural and medicinal values implying potential need for their conservation.
