摘要：ABSTRACTHazarikhil Wildlife Sanctuary (HWS), located in the Fatikchari upazila of Chittagong district, Bangladesh with a land area of 2,908.5 acres, is a Protected Area IUCN Category II. Once the forest was very rich in flora and fauna but apparently, it seems that some lesser known species may have been disappeared from the area due to changes in overall conditions. The study was conducted through systematic quadrat method where the size of the plot was 20 m×20 m. A total of 162 tree species (having ≥5 cm diameter at breast height (dbh)) belonging to 50 families were recorded where Euphorbiaceae family possess the highest number of species (18) followed by Moraceae (12 species). Conservation status of the plants indicated that 52% species (85 species) were Least Concern (LC) which was maximum among the conservation categories. However, the Vulnerable, Endangered, Near Threatened and Critically Endangered tree species were represented by 20% (32 species), 6% (9 species), 1% (1 species) and 2% (3 species) respectively. The study created a baseline of information on the tree species diversity of the protected area which is expected to be helpful to the future researchers as well as in taking managerial actions by the policy makers.
