Disponibilité des produits forestiers non ligneux fondamentaux à la périphérie du Parc national de Lobeke

Non-Timber Forest Products are appropriate to meet the needs of local and indigenous communities surrounding the National Park of Lobéké. In order to better assess their availability, a botanical inventory has been carried out. The methodology use to develop the inventory consist into the establishment of transect in the village of Mambélé. The village is located in the area of the Tri National of Sangha, more precisely in the South-East of Cameroon. In total, 9 transects of 2 km long and 20 m large allow the team to cover an area of 36 ha. Therefore, these transects helped identifying 29 individuals of Irvingia gabonensis, 204 individuals of Ricinodendron heudelotii, 54 individuals of Entandrophragma cylindricum, and 154 individuals of Terminalia superba. In addition, some interesting results are coming out from the calculation of species densities and variances analysis with ANOVA methodology : the availability of each species was linked mainly to two parameters, which include the type of land use area (old secondary forest, secondary forest, swamp forest, young fallow and old fallow) and the distance for harvesting. Therefore, most of identify species are found in secondary forests and old secondary forests. From the analysis, we notice that the diameter class] 20-40 [ is the class where we found most individuals from each species. To conclude, domestication of these Non-Timber Forest Product could be recommended as an alternative option to strengthening the economy and thus contributing to the conservation of biodiversity

Disponibilité des produits forestiers non ligneux fondamentaux à la périphérie du Parc national de Lobeke

Les Produits forestiers non ligneux (PFNL) sont nécessaires à la satisfaction des besoins des communautés locales et autochtones dans la zone périphérique du Parc national de Lobéké. Afin de mieux évaluer leur disponibilité, un inventaire botanique a été réalisé à la suite d’un échantillonnage basé sur la mise en place des transects dans le village de Mambélé. Ce village est situé dans la zone de la Tri nationale de la Sangha (TNS), plus précisément au sud-est du Cameroun. Au total, 9 transects de 2 km de long et 20 m de large ont été parcourus, pour une superficie de 36 ha. Ces transects ont permis de répertorier 29 individus d’Irvingia gabonensis, 204 individus de Ricinodendron heudelotii, 54 individus de Entandrophragma cylindricum, et 154 individus de Terminalia superba. Le calcul des densités de chaque espèce et l’analyse des variances par la méthode d’ANOVA révèlent que la disponibilité de chaque espèce varie selon deux principaux paramètres notamment : le type de milieux (forêt secondaire âgée, forêt secondaire, forêt marécageuse, jeunes jachères, vieilles jachères, champ) et la distance à parcourir pour la récolte. Les espèces identifiées se retrouvent en majeure partie dans les forêts secondaires âgées et dans les forêts secondaires. Il ressort aussi de l’analyse que la classe de diamètre la plus importante où l’on retrouve le plus d’individus de chaque espèce est la classe [20-40[. La domestication de ces PFNL pourrait donc être préconisée comme option alternative pour le renforcement de l’économie locale et contribuer ainsi à la conservation de la biodiversité.Non-Timber Forest Products are appropriate to meet the needs of local and indigenous communities surrounding the National Park of Lobéké.
