District Tor Ghar is phytosocilogically unexplored region in the western Himalaya. Present study was conducted in district Tor Ghar during the summers of 2012 and 2013 to study floristic diversity of herbaceous flora in the region. The district Tor Ghar is located on 34° 32′ - 34° 50′ N, and 72° 48′ - 72°58′ E. A total of 229 herb species belonging to 168 genera and 66 families were identified. Herbaceous vegetation was sampled from 1 × 1 m quadrats. For vegetation classification into plant communities, presence, absence (1,0) data on 229 herbaceous species and 64 locations were analyzed in PCORD version 5 via Cluster and Two Way Cluster Analyses. Six plant communities were established. Plant abundance data were treated in CANOCO version 4.5 to measure the ecological gradient of plant species and communities of the region. Detrended Correspondence Analysis (DCA) a type of indirect gradient analysis reconfirmed the results of Cluster and Two way Cluster Analysis. Moreover the study furnishes useful information for improvement, protection and management of present vegetation status for future generation. A comprehensive conservation measure with practical implementation is utmost necessary for conservation of rapidly depleting plant resources of the area.
