Prosopis africana is an important species with hard wood. Because of reason, this resource is very exploited by the local population for their daily survival threatening his durability. In order to know the importance of this plant in the peasant level, the present study was carried out in the Far-North, Cameroon, precisely in Holom soil. The objective of this study was to check off the different usages of P. Africana and to characterize the population of this species. The methodological approaches adopted to achieved this objective were the socio-economical investigation realized randomly close to 245 persons; the floristic inventory made on one area of 6.5 ha. The results show that, all parts of P. africana are important for the population. Branches (31 %) are used for fabrication of mortar, confection of shed, attic etc...leaves (16 %) are useful for cattle nutrition. Roots intervene in traditional pharmacopoeia at 5 % only. The wood of this species is very used as firewood (62 %). Globally, 38.46% of interviewee affirmed that the frequency of exploitation of this tree is very raised. According to dendrometrics parameters of P. africana, the results show a dominance of individuals with 5 to 10 m (45.56 %) of height, 20 to 60 cm (58.22%) of Diameter of the breast height, presenting bell distribution and a natural regeneration with height inferior or equal to 0,5 m (54,87 %) less represented. In front of the overexploitation of P. africana, the awareness of the population in the mode of effective management and the setup of rapid way of regeneration of this one are necessary to save the species for the interest of futures generations.
