Abstract

In this study, an attempt have been made to analyses the changes of forest cover of Kuno Wildlife Sanctuary using temporal satellites images of Landsat TM of 05th May 1990 and IRS LISS III P6 of 02nd March 2008. Normalized Difference Vegetation Index (NDVI) and digital image classification were used to generate the landuse/landcover of the sanctuary along with extensive ground truthing in 2008. SOI toposheets and other related information was used as an aid in feature extraction for the period of 1990. The NDVI values were derived and interpreted using ground filed surveys. Image differencing method was used to analyze the change detection of the landcover classes. The landuse/landcover were classify into 9 classes as Mixed Forest, Shallow water, Grassland, Village/ Forest camp area, Barren land, Dense forest, River , Open scrub and forest fire. The derived NDVI values varies from -0.27 to +0.62 in 1990 and -0.433 to +0.096 in 2008 respectively. The varied NDVI values indicates that vegetation cover was evenly distributed and reflected in the period 1990 while in 2008 there were highest reflectance of bare soil. However, it was observed that from May 1990 to March 2008, dense forest and mixed forest area increased up to about 28.83% and 7.94% in the abandon village areas and barren land. Grassland has also shown some improvement (3.16%) over the periods. The overall change detection is that the village areas and barren land before rehabilitation of the villagers were converted to high density grassland and mixed forest after rehabilitation which indicates a positive sign of management of the sanctuary.
