Abstract
The spatio-temporal analysis of forest cover change, forest health degradation
and fragmentation could provide base line information for achieving sustainable
forest conservation and management goal. In this present study we analyzed the
forest health degradation and fragmentation dynamics analysis using Remote
Sensing (RS) and Geographical Information System (GIS) in and adjoining region
of Buxa Tiger Reserve (BTR), India. Data from Landsat TM 4 and 5 and Landsat
8 OLI of 1990, 2000, 2010 and 2019 were used. Normalized Difference Vegetation
Index (NDVI) were applied to estimates forest cover heath and post classification
change detection techniques was performed and calculating the rate of change
(RC) commonly used in forest degradation change studies. To validate it overall
accuracy and Kappa statistics were calculated. It finds out -68.68% (217.04 km2)
of dense forest cover decreased, while 49.88% (71.02 km2) of overstressed open
forest cover, 12.65% (12.07 km2) of stressed degraded forest cover and 38.72%
(115.05 km2) of tea plantation areas increased respectively. The result from pixel
counting of forest fragmentation class map shows that there is continued decrease
in the large core forest area while an increase in the perforated forest, patch and
edge area took place within the period. The results of the present study could
provide quantitative information which is essential for further management of this
forest environment and for taking actions plan to mitigate the forest degradation
and fragmentation.
