Abstract

The eastern Himalaya region is a rich repository of medicinal plants.  Excessive collection and unsustainable harvesting of medicinal plants from the wild are leading to a depletion of populations and threatening species in the region.  A study was conducted to explore the diversity, distribution and population status of selected medicinal plants species in the higher altitudes of Arunachal Pradesh, India through extensive field surveys and consultations with the local communities.  Out of about 75 medicinal plants recorded, 41 rare and commercially important medicinal plants were observed in the sub-temperate to alpine forest within an altitudinal range of 1500–4500 m.  Taxonomically these species fall under 25 families of higher plants, of which 31 are dicots, seven are monocots and three gymnosperms.  Many threatened species like Taxus wallichiana, Coptis teeta, Panax pseudoginseng, Panax sikkimensis were recorded in specific localities.  The western part of the state exhibits maximum species diversity.  Out of the various threats observed, improper harvesting, habitat loss and trade are found to be more destructive to the population.  Intensive efforts from both in situ and ex situ conservation practices are necessary for sustainable management and conservation of these species.
