Abstract

ABSTRACT Wetlands are one of the crucial natural resources. Wetlands are areas of land that are either temporarily or permanently covered by water. Wetlands support a large variety of plant and animal species adapted to fluctuating water levels, making the wetlands of critical ecological significance. However, the very existence of these unique resources is under threat due to developmental activities and population pressure. In this paper attempt is made to analyse the planning for preservation and conservation of wetland resources. To find out the wetlands in the study area used the multispectral data for accurate results. In the study area numerous small and important wetlands found and prepared a map at 1:50,000 scales. The multispectral data collected two time period of IRS: LISS- III data acquired during pre and post monsoon season are used for inventory to account for wet and dry season hydrology of wetlands. The map outputs include the status of water spread, aquatic vegetation and turbidity. Ancillary layers like road/rail, habitations are also created. The results are complied for prepare wetlands map of Bagalkot District. This map highlights the characteristics of the wetlands in the particular area within the district and hopes to improve our understanding of the dynamics and distribution of wetlands and their status in the study area. At present urgent need to take various conservation activities through the action plans by the concerned state government.
