Abstract

The present study evaluates the changes in Forest cover pattern of Periyar Tiger Reserve, Kerala, India. satellite imageries of different time periods, i.e. Land sat 7 and sentinel-2 were obtained from the UnitedStates Geological Survey (USGS) Earth Resource Observation and Science Data Centre. Land sat 7 was usedfor the year 2001 and the sentinel-2b are used for the year 2021. The images of study area were classifiedinto six different classes. The results obtained from the forest cover change, shows that Evergreen (15.19sq.km), moist deciduous (35.107 sq.km), grassland (35.209 sq.km), thickets (13.53 sq.km) had decreasedand the semi evergreen (110.5196 sq.km) had increased. The normalized difference vegetation index (NDVI)analysis has been integrated for improving the classification accuracy.
