Present research paper is an attempt to examine the dynamics of timberlines by using the Normalized Difference Vegetation Index (NDVI) in the Gori Ganga watershed, Kumaun Himalaya, Uttarakhand (India). For the study of detect timber lines dynamics used of Landsat-5,8 and Cartosat-1 satellite imageries of three different time periods like Landsat-5 Thematic Mapper (TM) of 1990, Landsat-5 (TM) of 1999 and Landsat-8 Operational Land Imager and Thermal Infrared Sensor (OLI and TIRS) of 2016 and Cartosat-1 of 2008. Geographical distribution of average timberline height reveals that in 1990 about 3516.11 m, in 1999 about 3680.69 m and in 2016 about 4060.58 m which is Change from vegetation to timber area and during 1990-1999 about 197.58 km2 areas and during 1999-2016 about 463.95 km2 area of the Gori Ganga watershed was converted from non-timber to timber area. These data suggest that due to global warming, about 544.47 m timberline average height and 661.53 km2 timber area of Gori Ganga watershed has been shifted into non-timber cover to timber cover area at an average rate of 20.94 m/year and 25.44 km2/year from 1990 to 2016.
