The present study aimed to investigate the status of Isodon rugosus dominated communities in Khwazakhela swat. Various phytosociological attributes of all the recorded species were obtained. For quantitative analysis of vegetation a 4×4 m2 quadrat was used and a total of ten stands were sampled. Five quadrats were taken randomly per stand. Descriptive information such as altitude and aspect of the sampling site were recorded. For classification and ordination of vegetation data Ward’s Cluster Analysis and NMS (Non-metric Multidimensional Scaling) ordination was applied using PC-Ord software which results into the formation of four communities groups at 50% remaining information of the species. The highest values IVI, density/ha and cover/ha of Isodon rugosus was recorded in communities’ group I while lowest value of IVI, density/ha and cover /ha was recorded in community group 3 which is due to the anthropogenic disturbance as observed during field survey.
