Status of Orcidns in Buxa Tiger Reserve

Abstract

Buxa Tiger Reserve (West Bengal) is very rich in orchids. The survey conducted by the authors during 1994 and 1995 revealed the existence of at least 144 species (including 5 varieties) of orchids many of which are rare and endangered. 34 species of orchids were found over plantations. 6 species of orchids were also seen over shrubs. As many as 109 species of orchids have been found to be uncommon or scarce within the Reserve. Part of the Reserve notified as Sanctuary and National Park provides protection to only 44 species. Wet Hill Forests provide shelter to 63% of orchid species though these are mostly unprotected and affected badly by dolomite mining and illegal cultivation of oranges. Existing forestry practices in the buffer zone also harm orchids. Suitable suggestions have been made for the long term management and conservation of orchids in the Reserve.
