Bhuiyan 2200552The study describes the structural composition of a degraded forest of Chittagong, Bangladesh. Stratified random quadrat was used in this study. Tectona grandis was found as dominant with 28.87% of the total individuals, Diameter at Breast Height (DBH) range less than 5 cm represent highest percentage (66.14%) of all the individuals however the largest DBH range >17 cm represent only 0.84% of all the individuals. The number of trees and the number of species was the highest (158 and 32, respectively) in the <5 cm DBH range and least number of trees and species (1 and 1) was represent in 15-16.9 cm DBH ranges. Height class <3 m consist of the highest individuals (55.67% of total population). Tectona grandis showed the highest percentage (28.8%) followed by Ficus hispida (12.97%), Eucalyptus camaldulensis (7.53%), Albizia lebbeck (5.86%) and Gmelina arborea (5.44%). Number of trees and species are decreased with increasing height and DBH classes. This may be due to recent adopting management measures like protection of the area for biodiversity conservation.]]>Das, D.,198097186Nath, T.K., M.K. Hossain and M.K.
