Résumé
The conservation status of the vulnerable endemic tree Gilletiodendron glandulosum (Fabaceae) was assessed in southwestern Mali. Using basic forestry methods, structure and composition of Gilletiodendron forest were analyzed. Additionally, Maninka names and uses of characteristic plants were recorded. Of 126 species collected, 11 are new records for Mali. The vegetation is overwhelmingly dominated by Gilletiodendron glandulosum , although Grewia bicolor (Tiliaceae) and Hippocratea indica (Celastraceae) are also important. Based on floral composition, this plant community is a type of Sudano-Guinean gallery forest, its distribution probably determined by edaphic factors. Use of characteristic plants is low, although the endangered shrub Vepris heterophylla (Rutaceae) appears locally overharvested. Gilletiodendron glandulosum has sufficient economic value to the Maninka people to be potentially overharvested if human population growth continues. No current conservation measures specifically benefit Gilletiodendron forest, although it is passively protected due to its occurrence in marginal areas within the Maninka land use system.
