Resumo

The present study was carried out to study the wetlands of Jharkhand using pre-monsoon and post-monsoon satellite data. Different indices were used to quantify the seasonal extent of wetlands, aquatic vegetation and turbidity levels of wetlands. Wetlands occupying an area smaller than 2.25 ha were identified separately as small wetlands. The total number of wetlands identified in Jharkhand was 2436 covering an area of 1568.27 sq. km. Small wetlands were 13327 in number. Rivers/streams and reservoirs occupied more than 90% area of total wetland area. Wetlands mostly exhibited moderate turbidity. Spatial geodatabase generated in the present study will be useful for the planning and monitoring of wetlands for their continued ecosystem services to the society. Major wetlands may be further developed as the prime sites of tourist attraction Keywords:
