The present study aimed to investigate the status of Plectranthus rugosus dominated communities in Kabal 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 altitude of the sampling site was recorded. For classification and ordination of vegetation data Ward’s Cluster Analysis and Nonmetric Multidimensional Scaling (NMS) 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 Plectranthus 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.
