Sahastradhara is situated in Shivalik foot hills of district Dehradun. Lime stone mining and tourism has affected the floristic diversity of the area. The present study was conducted in three different sampling communities which were selected from quite different habitats with conspicuously different physiognomic, floristic and species richness characteristics and represented by different classification types of vegetation. Phytosociological observation indicates that all three communities were having invading plant species such as Eupatorium adenophorum, Lantana camara, Partheniumhysterophorus, Amaranthusspinosus etc., which is due to human interference as well as climate change along with change in soil profile. Forest community is more diverse and heterogeneous (3.26) then other communities (2.29 and 2.79). Values of concentration of dominance (Cd) prove that the plant communities are not dominated by single species.

 

Keywords: Community; Floral diversity; Phytosociology; Sahastradhara.
