Population structure and traditional management patterns of two threatened medicinal tree species (Garcinia lucida and Pausinystalia johimbe) in the southern humid forest of Cameroon
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 7, Issue 1
Abstract
Garcinia lucida and Pausinystalia johimbe are two medicinal tree species well-known in southern Cameroon as they provide non-timber forest products. Particularly, their barks and sometimes fruits, seeds and leaves of G. ludica are used to cure many ailments in local communities. Unfortunately, natural stands of both species are seriously threatened in Cameroon. The objectives of the study were to document use of the targeted species, their management patterns and assess their populations’ structure to establish better plans for the sustainable management and conservation. Ethnobotanical and quantitative ecological methods were used. The results showed that both species provided several products and services. The most mentioned services were the conservation of foodstuffs and medicine. Community responses indicated that the species became rare and there were no strategies developed to preserve them. The quantitative inventories supported this community’s view. Indeed, both species showed weak size classes’ distribution and low densities respectively 14.52 individuals/ha for G. lucida and 58.63 for P. johimbe. In addition, both species appeared to be threatened because of poverty and increasing demography, illegal logging, shifting cultivation, overexploitation and poor attitude to their conservation. Furthermore, because of the high value of these species of local, national and international levels, respondents claimed that they were interested in domesticating and conserving them but they lacked appropriate propagation techniques, materials and skills. Thus, the sensitization and the domestication of the species should urgently be considered in the farmer environment with strong sound of policy.
