Abstract

• A quantitative study of tree species was carried out in Shinma taung hill, Yesagyo Township. To find out the diversity of trees and to know the forest stand structure, 20 quadrates [20m x 20 m] in the study site were established and studied. Species diversity was presented by diversity index. In the study area, Shannon Wiener’s index and Simpsom index were 4.24 and 0.74. In the present study, 54 species, 44 genera belonging to 29 families were found in study area. Relative density, relative frequency, mean basal area and relative dominance were calculated. IVI values of major tree species were presented by ranking order. In this study area, ecologically the most successful species were Tectona hamiltoniana Wall. (Dahat) 58.13%, Terminalia oliveri Brandis (Than) 47.88%, Hiptage benghalensis (L) Kurz. (Bein nwe) 14.86%, Bridelia retusa (L.)A.Juss (Seik chi) 11.95% and Capparis flavicans Wall (Saung gyan) 9.17%. It was influenced by Tectona hamiltoniana Wall. (Dahat) and Terminalia oliveri Brandis (Than) in this region.
