Present research paper is an attempt to examine the dynamics of vegetation line by using Normalized Difference Vegetation Index NDVI method in Gori Ganga watershed, Kumaun Himalaya, Uttarakhand India . For the study of detect vegetation line shifting used of Landsat 5,8 and Cartosat 1 satellite imageries of three different time periods, i.e., Landsat 5 Thematic Mapper TM of 1990, Landsat 5 TM of 1999 and Landsat 8 OLI and TIRS of 2016 and Cartosat 1 of 2008. Geographical distribution of vegetation line average height reveals that in 1990 about 4294.97 m, 1999 about 4394.51 m and in 2016 about 4758.55 m which is change from non vegetation to vegetation area. During 1990 1999 about 150.67 km2 areas and during 1999 2016 about 434.03 km2 area of the Gori Ganga watershed was converted from non vegetation cover to vegetation cover area. These data suggest that due to global warming about 463.58 m vegetation line average height and 584.70 km2 vegetation area of Gori Ganga watershed has been shifted into non vegetation cover to vegetation cover area at an average rate of 17.83 m year and 22.49 km2 year during 1990 to 2016.
