Abstract: Uncontrolled harvesting of non-timber forest products
(NTFPs) poses a serious risk of extermination to several of these species
in Nigeria. Yet, there is a paucity of information on the distribution,
population status and sustainable management of NTFPs in most of the
tropical lowland rainforests. We, therefore, assessed the population,
distribution and threats to sustainable management of NTFPs within the
tropical lowland rainforests of Omo and Shasha Forest Reserves, south
western Nigeria. Data were obtained through inventory surveys on five
top priority species including: bush mango (Irvingia gabonensis (Aubry-
Lecomte ex O'Rorke) Baill), African walnut (Tetracarpidium conophorum
(Mull. Arg.) Hutch. & Dalziel syn. Plukenetia conophora),
chew-stick (Massularia acuminata (G. Don) Bullock), fever bark (Annickia
chlorantha Setten & P.J.Maas syn. Enantia chloranta) and bush
pepper (Piper guineense Schumach. & Thonn.). Purposive and stratified
random sampling techniques were used for the inventory. Each forest
reserve was stratified into three, viz: less disturbed natural forest (for
areas that have been rested for at least ten years), recently disturbed
natural forest (for areas that have suffered one form of human perturbation
or the other in the last five years), and plantation forest (for areas
carrying forest plantation). Data were collected from eighteen 10 m ×
500 m belt transects located in the above strata. The species were generally
fewer in both plantation and recently disturbed natural forest than the
less disturbed natural forest, suggesting that forest disturbances (habitat
modification) for other uses may have an effect on the occurrence and
densities of the NTFPs. Exceptions to this trend were found for P.
guineense and T. conophorum, which were fairly common in both planta
