The protected areas of Himachal Pradesh in the Indian Himalayan Region are facing high anthropogenic pressure due to grazing rights. Habitat degradation coupled with overexploitation of sensitive biodiversity elements has caused habitat alteration and rapid decrease in their populations. This has necessitated evaluation and prioritization of habitats and communities and suggest strategies for conservation. The present study has focused on these lines and has identified 13 habitats, 23 forest communities and 24 alpine communities. Each habitat and community has been evaluated for site representation, altitudinal distribution, species richness, native, endemic socio-economically important and threatened species. Based on cumulative values for these attributes, Conservation Priority Index (CPI) for the habitats and communities has been calculated. Amongst habitats, shady moist forest, bouldary, rocky, dry forest and alpine moist slope habitats respectively, showed high CPI, and were hence prioritized for conservation. Amongst communities, Betula utilis, Abies pindrow, Cedrus deodara and Picea smithiana in the forest zone and Rhododendron campanulatum, Rhododendron anthopogon, Cassiope fastigiata
