ABSTRACT

Wildlife Sanctuaries are vital because they are established by law to protect endangered and threatened species of plants and animals. They play a precious role in balancing the ecology of a region. Routine assessment of Land Use Land Cover is imperative in Wildlife Management because landuse and land cover change studies indicate variations and help to detect dominant changes over the region. This study aims to understand land use land cover changes in Cotigao Wildlife Sanctuary with the use of remotely sensed data from IRS, LISS III satellite images for 2008 and 2018. Primary data, as well as secondary data, is used in various forms. GPS surveys have been conducted for ground-truthing and collection of new geospatial data as a primary data source. LISS III satellite imageries are processed and analysed using remote sensing image processing software ERDAS IMAGINE 2014 (HGM, US), and ENVI 5.3 (Harris Geospatial, Colorado, USA). For mapping of the final output, ArcGIS 10.3 (ESRI, California, USA) software is used. During 2008-2018, the area under Dense Mixed Jungle has decreased by 11.74 per cent. The area under settlement and agriculture has shown an increase by 3 and 2.08 per cent respectively. During the study period, the area covers water bodies, grasslands and plantations depicts a negative change with -0.33, -2.5 and - 0.93 respectively. Two land classes namely Fairly Dense Mixed Jungle and Open Scrub have increased by 5.16 and 5.26 per cent respectively for the same period.
