Description of the subject: This article presents the influence of the exploitation of NWFPs in improving the living conditions of village populations and floristic diversity. Objectives: The investigations made it possible to estimate the potential of available NWFPs; identify outlets and marketing channels; analyze the uses and sustainability of harvesting methods. Method: A botanical inventory is carried out in UFA 00-001 and 00-002 of the company TRC near 17 Bantu villages and 6 pygmy hamlets which use and market NWFPs. Socio-economic data are obtained by the Accelerated Participatory Research Method (APRM). Results: Sixty species of NWFP belonging to 49 genera and 28 families have been identified. Up to 84.50 and 15.49% of households complain about the decrease in the frequency of occurrence of Baillonella toxisperma Pierre and Ricinodendron heudoletii (Baill.) Pierre ex Heckel, respectively. 51.64% predict a disappearance of Baillonella toxisperma Pierre. Only 10% of the households have tried to plant this species and none have tried to plant Ricinodendron heudoletii (Baill.) Pierre ex Heckel. Baillonella toxisperma Pierre and Ricinodendron heudoletii (Baill.) (Baill.) Pierre ex Heckel are sold respectively at 1500 Fcfa per liter and 1200 Fcfa per kg. These two species generate respectively 4,859,400 Fcfa and 4,885,440 Fcfa in all the villages studied. The average income for a household is 9,255 Fcfa. Conclusions: Baillonella toxisperma Pierre and (Baill.) Pierre ex Heckel contribute to the income of the households which market them. But their exploitation constitutes a threat to the sustainability of these two species.
Author Keywords: species, food, traditional medicine, protection, disappearance, Cameroon.

Description du sujet : Cet article présente l’influence de l’exploitation des PFNL dans l’amélioration des conditions de vie des populations villageoises et la diversité floristique. Objectif. Les investigations ont permis d’estimer le potentiel de PFNL disponible; identifier les débouchés et les circuits de commercialisation; analyser les utilisations et la durabilité des modes de prélèvement. Méthode : Un inventaire botanique est réalisé dans les UFA 00-001 et 00-002 de la société TRC proches de 17 villages bantous et 6 hameaux pygmées qui utilisent et commercialisent les PFNL. Les données socio-économiques sont obtenues par la Méthode Accélérée de Recherche Participative (MARP). Résultats : Soixante espèces de PFNL appartenant à 49 genres et 28 familles ont été identifiées. Jusqu’à 84,50 et 15,49 % des ménages se plaignent de la baisse de la fréquence d’apparition respective de Baillonella toxisperma Pierre et Ricinodendron heudoletii (Baill.) Pierre ex Heckel. 51,64 % prédisent une disparition de Baillonella toxisperma Pierre. Seulement 10 % des ménages ont essayé de planter cette espèce et aucun n’a essayé de planter Ricinodendron heudoletii (Baill.) Pierre ex Heckel. Baillonella toxisperma Pierre et Ricinodendron heudoletii (Baill.) Pierre ex Heckel sont vendus respectivement à 1500 Fcfa le litre et 1200 Fcfa le kg. Ces deux espèces génèrent respectivement 4 859 400 Fcfa et 4 885 440 Fcfa dans l’ensemble des villages étudiés. La recette moyenne pour un ménage est de 9255 Fcfa. Conclusions : Baillonella toxisperma Pierre et Ricinodendron heudoletii (Baill.) Pierre ex Heckel contribuent aux revenus des ménages qui les commercialisent. Mais leur exploitation constitue une menace pour la pérennité de ces deux espèces.
