| Abstract | In the face of continuous forest degradation, the Village Common Forests (VCFs) are the relics of biodiversity richareas that are traditionally conserved by indigenous communities for a long time in Chittagong Hill Tracts (CHT), Bangladesh. Avegetation survey was conducted in four VCFs of Khagrachori district to ascertain the phytosociological attributes of VCFs. Weset nine quadratic plots (each 10 m ? 10 m) for every VCF following three plots in each of base, mid and top of the hill. We hadidentified the species and measured the diameter of trees ? 1 m in height. Biodiversity indices of tropical forests were alsocollected from published literatures to compare the biodiversity of VCFs and other tropical countries. The results of thephytosociological study revealed that 124 species belonging to 44 families were found in VCFs of Khagrachori district. Thedominant family was Euphorbiaceae followed by Moraceae and Rubiaceae. Importance value index (IVI) indicated that thedominant species was Oroxylum indicum (32.34) followed by Vitex peduncularis (13.14) and Grewia nervosa (12.90). The valueof Shannon-wiener diversity index (H?), Simpson index (Ds) and Evenness index (EI) of VCFs were 3.26, 0.929 and 0.486respectively. Analysis of biodiversity indices among the forests did not show any significant (p? 0.05) difference indicating thatthe biodiversity status of VCFs was similar to other natural forests. Moreover, the VCFs of Khagrachori district harbored eightleast concerned (LC) and three threatened (T) species of the country. Therefore, we suggested that the forest managers and thepolicy makers of the country should pay sincere attention to the conservation of local biodiversity through VCFs. |
