Green Heritage in N. E. Region and its Conservation

Large variation in altitude, soil, temperature and rainfall of the North-eastern region has contributed immensely to the rich biological diversity. The region is also considered to be home of several primitive angiosperms, centre of speciation, with substantial endemics and progenitors of many cultivated and other economic plants viz., Amomum, Cardamum, Citrus, Dioscorea, Musa, Piper, Prams, Pyrus, Rubus, Trichosanthes, Zingiberand orchid etc. It is appropriately considered as a cradle of plant evolution. However, the man himself disrupting the natural ecosystems at a terrifying rate, and in many parts of the region, these limits have already been transgressed resulting in the depletion of genetic wealth considerably. As a result, several plant species have already dwindled in natural habitats, while a few are on the verge of extinction.

In the present paper the rich bio-diversity met within this region along with its threat has been highlighted. Conservation strategy for their survival has also been discussed.
