The composition and diversity of native tree species in all topographical positions
of Dud-Pukuria Natural Forest in Chittagong (South) Forest Division, Bangladesh were
investigated. A total of 667 individual stems having dbh >10 cm were recorded from 3.2
hectare sampled area. These 77 native tree species belongs to 32 family and 53 genera
Diversity and distribution pattern of tree species of Bamu Reserved Forest of
Cox’s Bazar were studied by count plot method for analysing stand composition. A
total of 85 tree species were recorded from the forest of which 77 species belonging
to 30 families were identified. Leguminosae and Moraceae ranked top with seven
species followed by Verbenaceae and Euphorbiaceae each with six species. The
Importance Value Index (IVI) of each species was calculated to characterize the
composition of vegetation. Bursera serrata showed the highest (18.91) IVI followed
by Artocarpus chania (14.82), Pterospernium acerifolium (14.04), Hopea odorata (13.73),
Glochidion multiloculare (13.19) and Vitex peduncularis (10.51). Distribution of the
number of individuals of each species in nine diameter classes ( 80cm with
10cm intervals) were calculated with respect to total individuals. It showed that
maximum percentage of individuals (35.08%) belonged to 80cm) represented the lowest percentage (1.82%).
Bursera serra tahad the highest (8.04%) percentage distribution followed by Glochidion
multiloculare (7.67%), Dipterocarpus turbinatus (5.85%), Hopea odorata (5.36%),
Pterospernium acerifolium (4.87%), Bauhinia acuminata (4.03%) and Lagerstroemia speciosa
(3.05%). The rest of the species had values < 2.8%.
