Forest resources are the most diverse and widespread ecosystem that provides clean air, water, timber, food, fuel, fodder, medicinal plants, agricultural implements, construction materials and recreational opportunities on earth. Hosadurga taluk is classified as one of the Hot Spots of Indian Flora & Biogeographic zone of this study area falls under the Deccan Peninsula Zone. According to 1999 assessment of the Karnataka Forest Department, Hosadurga taluk holds 14% spread of forest cover which includes forest plantations; degraded forests; moist & dry deciduous forests and scrub types. There is a significant change in forest cover around the globe due to rapid rise in population, land use, forest fire, demand for economic mineral deposits, depletion of rainfall, climate change and global warming (?). The present aim is to focus mainly on planning and management of forest cover for environmental and socio-economic outcome to meet future needs. Mapping of forest cover and its Change Detection Analysis (CDA) is prepared using Survey of India (SoI) topomap of 1:50,000 scale; geo-rectified multi-spectral and multi-temporal satellite images of IRS-1C/1D PAN+LISS-III of 5.8m resolution through GIS software’s. The study area endowed with 5 State Reserved Forests which covers total area of 201.62 Km2 (1975-78) which has been degraded due to human intrusions through agricultural patterns, depletion of rainfall, illegal mining etc. The final results highlight change detection in forest cover using multi-temporal satellite image using geo-informatics for its monitoring and sustainability.
