摘要

The present study deals with periodic assessment and monitoring of the mangroves of Bhitarkanika Wildlife Sanctuary, Orissa, India using remote sensing and Geographic Information System techniques. Satellite data of Landsat MSS for 1973, IRS-1A LISS II for 1988 and IRS-P6 LISS III for 2004 along with other spatial and non-spatial data were used to find out the changes that occurred in mangrove and other land-cover categories during the last 30 years. It was found that the sanctuary is occupied by agriculture (51.76%), followed by dense mangrove (21.77%), water bodies (20.19%) and open mangrove (2.73%). A loss of 1534 ha mangrove area and an increase of 2436 ha agriculture area clearly depict anthropogenic activities by local villagers. A significant increase of 270 ha plantations illustrates plantation activities taken up by the Orissa Forest Department to protect the coastal shoreline.
