Sikkim Himalayas are known for its rich biodiversity. Being part of the North eastern Region, which is one of the Biodiversity Hotspots, it is rich in natural resources and supporting a vast variety of flora and faunas. Over a period of time this region has experienced a phenomenal increase in the population; as a result, the rich native tropical evergreen forest has been exploited to a great extent. The Oak forest habitat, which is essentially a part of dense evergreen, and semi evergreen forest are gradually getting open up and exposed to further deterioration. Oak forests habitat, being sensitive to particular climate and physiographic conditions is likely to be affected due to the changing climate scenario. Present study is an attempt to investigate the influence of climate change on Oak forest habitat in Sikkim Himalayas. The current distribution of the Oak forest derived by using satellite remote sensing and field visits and the climate and topographic information has been used to generate climatic envelope of Oak forest habitat. Future scenarios of Oak forest habitat and their potential spatial distribution have been predicted for the year 2050 and 2100 through ecological niche modeling and Geo-spatial techniques.References
