摘要：The plant propagules migrate into denuded or conditionally created habitats by variety of means and grow, capable species establishes their population successfully and rest abolish. The present study was aimed to identify potential species in such habitats by evaluating naturalized community in conditionally crated habitats i.e. debris dumping sites of a hydroelectric power project in Western Himalayas, India for phytoretoration (eco-restoration) purpose. The data on phytosociological attributes of herbaceous community was collected from both debris dumping area (D) and undumped natural area (N) in the fringe, by quadrat method (1 x 1 m dimension). A total of 54 species from debris dumping sites and 128 species from undumped natural area (N) are recorded in this study. The invasive alien species predominates at dumping sites which covered 37% of the species richness, 50.99% of density, 76.67% of basal cover and 63.15% of dominance (IVI). Thus, invasive species are opportunistic in the process of phytorestoration in degraded habitats, which may not be beneficial for the better functioning of ecosystem but some of them can be considered as potential preliminary soil binder at such cases (dumping area). The development agencies must have an eco-restoration plan for such dumping zones which magnetized the encroachments of invasive alien species and play a pivotal role in degrading the natural ecosystem.
