COLOUR PLATES 1-18 AND MAP 1 & 2 1. INTRODUCTION On the southern coast of Gulf of Kachchh in the Saurasthra region ofGujarat lies a small wetland ecosystem with multitude of ecotones so intricately merged that it creates a unique wetland ecosystem complex known as Khijadiya Lake and Bird Sanctuary in the Jamnagar district of Gujarat. Unlike many other wetland environment where bird sanctuaries have been created, Khijadiya is no exception but houses combinations of seasonal freshwater shallow lakes, intertidal mudflats, creeks, salt-pans, saline land, mangrove scrub and above all sparsely occupied human habitation around it. The Khijadiya Lake and the Bird Sanctuary forms a part of wetland ecosystem ofGujarat state which has 36% of the total wetland area of the country. The state of Gujarat has few unique wetlands in its four different regions (Table 1). The area of Kachchh is geographically the largest region with highest percentage of total wetlands followed by Saurashtra with only 9.56 % of the wetland areas. Out of the 831 wetlands in the state, 438 are coastal and 393 are inland wetlands (including 231 small and big reservoirs). Table 1 : Wetlands in different regions of Gujarat Region No. of Wetland Area (km2)* 0/0 Area Wetland North Gujarat 159 1,107 4.08 Kachchh 258 21,772 80.12 Saurashtra 352 2,598 9.56 South Gujarat 62 1,698 6.24 Total 831 27,175 100 (Modifiedfrom Pandey and Teli. 2005) ·Wetlands smaller than 56 ha are not included in the table Gujarat has 2,092 km2 area under inland wetlands and that of the coastal wetlands has been 25,083 km2 (Pandey and Teli, 2005). Thus, the inland and coastal wetlands cover 7.7% and 92.3% of the total wetland area respectively (Table 2). This indicates that the large area is under wetland in the state and encompasses almost all kinds of habitat in its region with largest coastline of the country falling in the category of coastal wetlands. Area up to six meter deep of the coast and the mangrove zone are the most important habitat of the wetland in the Gujarat state. 2 Wetland Ecosystem Series. 15 Table 2 : Inland and Coastal Wetlands in Gujarat Inland Wetlands Area (km2) Coastal Wetlands Area (km2) Natural lake 154 Mangroves 1,031 Water logged 289 Coral reefs 130 Reservoirs 1,394 Mudflat 21,954 Tanks/ponds 198 Salt pans 460 Marshland 57 Other 1,508 Total 2,092 Total 25,083 Saurashtra has mostly coastal wetlands, whereas north Gujarat has all categories of wetlands except marsh/swamp vegetation. The north Gujarat's proximity to the Gulf of Kachchh and its desertic conditions has helped in the formation of mudflats. A large area is under mudflats. South Gujarat is bestowed with rivers Tapi, Narmada and the Mahi. Wetlands are mostly reservoirs and mudflats. There are 21 important wetlands in Gujarat as per Directory of Indian wetlands, Khijadiya Lake and Bird Sanctuary is one ofthem (Hussain and Roy, 1993). The name of the wetlands, their area and the important biodiversity is given in Table 3.
