The objective of this work is to identify the changing pattern of existing vegetation and the decreasing trend of green plants coverage in a temporal scale of view in the study area using NORMALIZED DIFFERENCE VEGETATION INDEX (NDVI) technique based on Remote Sensing (RS) and Geographical Information System (GIS). The vegetation cover and its spatial distribution have significant effects on the framework and function of the ecosystem and so vegetation plays an important role in climate change, it is also a dominating factor in maintaining the functions of the Earth's ecosystem. The Shergarh sanctuary is located in Shergarh village, about 65 km from the Baran district in Rajasthan. It is located in the Baran district and is spread across 97 sq km near the Shergarh town. For developing NDVI of the study area, two images of sentinel- 2 (2015-2021) have been collected from the USGS (United States Geological Survey) earth explorer website. To investigate NDVI values, it is categorized into three different classes like areas with low (0.2-0.4), medium (0.4-0.6), and high (>0.6) vegetation density based on NDVI ranges of both 2015 and 2021 images. The study reveals that there is a decline in low-density vegetation in recent years while medium and high-density vegetation has increased during the period. 11.7 percent of total vegetation was reduced in six years.
