Abstract
Orchids are prized for their incredible range of floricultural excellence, beautiful foliage and fragrant, that has exploited the group for commercial purpose or as a royal race of hobby. Destruction, opencast mining, anthropogenic pressures and other developmental activities has created heavy shrinkage of forest areas which leads regular threat of survival of entire orchid group. Many spectacular and economically important orchid species of Assam were facing danger of extinction. Open cast coal mining was one of the major menaces for the orchid flora of the Makum Coal field region. Majority of the orchids are found as epiphytes on tree and destruction of tree species due to mining created permanent elimination of the group. The present study was enumeration of natural diversity of orchids in Tinkopani, Kotha, Namphai and Namphuk Reserve Forest of Jagun range located Tinsukia district of Assam under Assam Valley Tropical Wet Evergreen forest belonging to the buffer zone of NE Coal field. Based on floristic survey of orchids, all together 76 species were recorded from the sites. A total of 68 species were epiphytic in nature and 8 species were terrestrial habit. Among them 2 species were placed under critically endangered, 12 were endangered, 14 were vulnerable and 14 were in rare category. Study highlighted the distribution of the species, their host range and ecological status.
