Abstract: 

Present study focuses the changes of vegetation cover (mangroves in forest region) in Sundarban during 2005 to 2015 based on the normalized difference vegetation index (NDVI). Seven vulnerable islands also reviewed which are positioned on the edge of south surface of Sundarban. The current survey reveals that approximately 1.07% vegetation area has been reduced during the period 2005-2010 and that of about 1.88% during 2010-2015. From the inspection of seven islands, it is seen that most of the islands are eroded more than 15% on the south region of the Sundarban because of submerging due to rising sea level. About 2.95% net vegetation area has been decreased during 2005 to 2015. This affect directly or indirectly on the normal biodiversity in Sundarban. It may also be inferred that the rate of depletion may be increased further in future. Therefore the study focuses to draw proper attention on extensive monitoring and managing the situation by arranging improvement of area of mangrove plantation.
