Different phytosociological attributes of woody vegetation were analyzed along a disturbance gradient in tropical dry deciduous forest of Hastinapur along the three sites. The disturbed site were surveyed for floristic composition, similarity index, concentration of dominance, species diversity, âdiversity at each stratum of woody vegetation. Maximum numbers of trees were recorded from undisturbed site (Site-3). Acacia nilotica, Tectonagrandis (tree species) were present on all the sites although in undisturbed site these species were less in number. Acacia nilotica was dominant species of Highly disturbed (Site-1) and Moderately disturbed (Site-2) sites, whereas on undisturbed site (Site-3) Acacia catechu and Tectonagrandis were the dominant species. Maximum similarity was observed between site-2 and site-3 (69.2%) and minimum between Site-1 and site-2 (25%). The value of CD and H' for trees were 0.01 on Site-2 to 0.035 on site-1 and 0.oo on site-3 to 0.014 on Site-1 respectively.
