ABSTRACT
Objective: This work has examined the current state of woodlands in the groundnut basin to determine its importance
Methodology and results: The floristic diversity of woodlands in the Groundnut Basin of was studied through ecological parameters. The woody flora contained 75 species with a predominance of three (3) families (Combretaceae, Mimosaceae and Caesalpiniaceae) represented by more than six (6) species. The statements from the four targeted rural communities indicated: 31 species for Ndiognick, 43 for Birkelane, 46 for Saly Escale and 48 for Ida mouride. The overall average density was 17 individuals/ha and varied depending on rural communities: 7 individuals/ha for Ndiognick, 9 individuals/ha for Birkelane, 18 individuals for Ida mouride and 39 individuals for Saly Escale. In Ndiognick and Birkelane rural communities, the cover was lower because they were less provided in species (Cordyla pinnata, Combretum glutinosum, Piliostigma reticulatum and Adansonia digitata) with summits higher than 5m2/ha. The flora and the woody vegetation selected parameters indicated that the level of organization of the woody species was not similar as well as the pressure on the woody species in the rural communities. The diversity of the wood species was reducing due to anthropogenic action and the deterioration due to climate conditions.
Key words: Diversity floristic, diversity index, impact index.
