Assessment of Forest Cover Dynamics using Forest Canopy Density Model in Sali River Basin: A Spill Channel of Damodar River Asish Saha, Manoranjan Ghosh, Subodh Chandra Pal, Indrajit Chowdhuri, Rabin Chakrabortty, Paramita Roy, Biswajit Das, and Sadhan Malik Abstract In a spatio-temporal scale, changing conditions of forest land cover and its detection study is an important concern for sustainable forest management. Nowadays, the forest canopy density (FCD) model has been used for the analysis and management of forest resources through identifying the forest gap areas where afforestation should be started immediately. The present study applied FCD model to detect changes in forest land cover in Sali River basin between the years 2000 and 2018. Moreover, the vegetation indices like Bareness Index (BI), Greenness Vegetation Index (GVI), Normalized Difference Vegetation Index (NDVI), Perpendicular Vegetation Index (PVI), and Shadow Index (SI) along with weighted overlay analysis have been used to prepare FCD map of the Sali river basin. It has been noticed from FCD map that south and north-eastern part of the study area covered with high canopy density in comparison with north and north-western region in the year 2000. Whereas, in the year of 2018, high FCD has been found in the middle portion of the southern region and the rest of the area varies from low to medium FCD.

global warming, enriching the level of groundwater and playing a role of carbon sink area for maintaining the balance of atmospheric Carbon-dioxide (FAO 2014; Halliday et al. 2003). However, the area under forest cover is gradually decreasing mainly due to human interventions. It has been estimated that out of the earth’s total land surface area, around 31% is covered with forest area; whereas, in case of India, it has been estimated that only 24% of country’s area is under forest (FAO 2010). The global forest area has been losing its area at the rate of 0.08% per year (FAO 2015). Therefore, the conservation and management of forest areas have become very important to solve the above me
