Abstract

Tropical forests of Bangladesh are facing rapid loss in floristic diversity and resultant changes of vegetation necessitates the assessment of plant composition and diversity. The present study was conducted to assess the composition of native tree species of Rampahar Forest Reserve of Rangamati hill district, Bangladesh. Rampahar is a remnant tropical semi-evergreen natural forest extending to an area of 648 ha. Simple random sampling method with 20 m × 20 m sized 20 and 5 m × 5 m sized 10 samples plots were used to study both tree species composition and seedling status of tree species. A total of 50 tree species under 28 families and 15 regenerating tree species under 13 families were recorded in the study area. Family Moraceae possessed the highest number of tree species (6 species) while families Anacardiaceae and Sterculiaceae possessed the highest number (2 species) for regenerating tree species. The survey indicated that Protium serratum (Wall. ex Colebr.) Engl. is the most dominant tree species with the highest relative density (RD), relative frequency (RF) and importance value index (IVI). Basal area of all the tree species was 13.13 m2/ha where Ficus religiosa was represented by the highest basal area (1.14 m2/ha). Protium serratum was also a dominant regenerating tree species with highest RD (15.24%), RF (16.30%) and IVI (50.09). The native trees species of this remnant forest need attention for immediate conservation
