Uttarakhand harbours 73 genera and 231 species of orchids out of which 54% are terrestrial, 41% epiphytic and 5% are saprophytic. Extrinsic rarity in orchids is a reflection of anthropogenic threatening processes which directly limit or reduce the distribution and abundance of species, such as collection of wild orchids or land clearance. Habitat protection could be one of the most important in situ conservation strategies for orchids. Microclimatic conditions play an important role in the establishment and distribution of orchid species. In the present study, an extensive field survey was carried out from the lower catchment area of Mandakini river (tropical forest) up to the upper sacred forest of Khombherav, in Garhwal division. A total 17 genera with 19 species were recorded. Majority of orchids were found epiphytic followed by terrestrial distributed between 1000-2600 m. Species of Dendrobium and Oberonia were found to be dominant. Coelogyne cristata, Pholidota articulata, and Satyrium nepalense were found to be used by local people as a medicine.
