The characterization consists of determining the legume woody flora density, vertical structure, number of sapling, herbaceous legume biomass and importance socio-economic. Firstly, we used systematic sampling approach to collect legume flora. A total 51 plots each with a size of 50 m x 50m for all parklands species and within each major quadrat, five sub plots of 5mx5m and 1 m x 1 m were established for the woody regeneration and for herbaceous biomass. All plant species in each plot were recorded. The legume flora was extracted. Some dendrometric parameters such as height, diameter at breast height (1.30 m) and the crown cover were measured. Secondly, we used ethnobotanical questionnaire to collect the socio-economic data about the importance of legume flora to the rural communities. On the other hand, a total of 61 legume species representing 30 genera and the three botanical families namely Fabaceae, Original Research Article
