Abstract: A total of 229 plants species were present in the study area. Out of which 35 were trees, 52 shrubs, 110 herbs and 12 climbers, 17 tree trunk vegetation ( in which 7 epiphytes, 5 pteridophytes, and 5 bryophytes) and 3 parasites occurring on stem and on branches of trees and shrubs. The study are divided into two elevations and per elevation four forest habitats as stream bank, dry, ridge and moist habitats. The maximum tree species were recorded on moist habitat at low elevation, stream bank and moist habitats at high elevation (19 spp each) whereas minimum on stream bank habitat at low elevation. The maximum shrubs species were recorded on ridge and at low elevation and minimum on ridge habitat at high elevation. The maximum herbs species were recorded on stream bank, dry and moist habitats (39 spp each) at low elevation. The minimum herbs species was stream bank habitat at high elevation. The maximum Climbers species were recorded on ridge and moist habitats at high elevation (6 spp each) whereas minimum on ridge habitat at low elevation. The mean trees species richness was found maximum on stream bank habitat (6.3±0.2) at low elevation and minimum on ridge habitat (3.5±0.2) at high elevation. The mean shrubs species richness was found maximum on moist habitat(6.1±0.3) at low elevation and mean species richness of herbs was found maximum on ridge habitat (10.3±0.4) at low elevation However, minimum shrubs and herbs species richness on stream bank habitat (3.2±0.3), (6.4±0.3) at low elevation. The mean climber species richness recorded was maximum on moist habitat (1.5±0.4) at low elevation and minimum on ridge habitat (0.7±0.1) at high elevation. The value of similarity was varied from 52.94% - 8 5.71% for trees layer, 48.28% - 75.00% for shrubs layer, and 22.45% - 68.04% for herbs layer and 42.86% - 76.92% for climbers layer respectively. It was high similarity on stream bank and moist habitats in both elevations.
