Abstract: The study determined the species composition of the study areas. This was with a view to determining some structural characteristics of the vegetation and the dominant tree species. 0.09 ha of two selected sample plot were established in the study area and woody plant species with girth and height of ≥ 1 cm and ≤ 1 m respectively were completely enumerated, identified to species level and their girth size were measured at breast height (gbh). The number of species, genera and families were established for the studied plots. The data collected were used to calculate species diversity index, basal area, species evenness and the stem density of tree species. The result showed that in Plot A, 55 plants (trees and shrubs)representing 25 species, 24 genera and 16 families and in Plot B, 49 plants (trees and shrubs) representing 19 species, 18 genera and 15 families were documented in each 0.09. Stem density was found to be 605 and 539 stem ha respectively. The basal area of the species in the plots were 27.4168 m² hand 12.87 m² hrespectively. The dominant tree species in the Agbeji (plot A) were Acacia senegal, Cochlospermum planchonii, Elaeis guineensis and in plot B Cochlospermum planchonii and Irvingia wombolu were the dominant species. The findings of this study serve as baseline information for monitoring the ecological dynamics of the study areas.
