Abstract
In order to assess the diversity, regeneration and structure of wild edible fruit trees, a study was carried out in the Laf-Madjam forest reserve and its surroundings. A semi-structured interview with local residents and a floristic inventory of woody plants (8 transects of 1000 m × 20 m each) were carried out. 24 species were cited as being used by the local residents. A total of 2134 individuals subdivided into 69 species, 43 genera and 27 families were counted, including 448 edible fruit individuals divided into 25 species, 19 genera and 14 families. The latter with important IVIs are: Balanites aegyptiaca , Sclerocarya birrea , Ziziphus mauritiana and Hexalobus monopetalus. Diversity is medium in edible fruit trees (HSI=3.10 bits, E= 0.67). Fruit trees with individuals of diameter ≥ 21 cm are in the majority. Inverted "L" and bell-shaped gaits are observed. The regeneration rate of fruit trees is higher in Annona senegalensis , H. monopetalus , and B. aegyptiaca . The involvement of local people in the management of the reserve's fruit trees is important for sustainable management. Key words : Edible fruits, Moutourwa, sustainable management, structure, phytodiversity.
