Explanation

Chilika Lake is the largest brackish water lagoon in Asia and the second-largest coastal lagoon in the world. It is one of the hotspots of biodiversity in the country. It is spread over the Puri, Khordha, and Ganjam districts of Odisha at the mouth of the Daya River, flowing into the Bay of Bengal. The north shore of the lake is part of Khordha District and the western shore is part of Ganjam District. Chilika Lake has been listed as a tentative UNESCO World Heritage site. In 1981, Chilika Lake was designated the first Indian wetland of international importance under the Ramsar Convention. It is the largest wintering ground for migratory birds on the Indian sub-continent. Birds from as far as the Caspian Sea, Lake Baikal, Aral Sea, and other remote parts of Russia, Kirghiz steppes of Kazakhstan, Central and Southeast Asia, Ladakh, and the Himalayas come here. The lake is home to a number of threatened species of plants and animals. Around 152 rare and endangered Irrawaddy dolphins have also been reported. The rare and threatened animal species identified are green sea turtle (EN), dugong (VU), Irrawaddy dolphin (EN), blackbuck (NT), Spoon billed sandpiper (CR), Chilika limbless skink (CR) and fishing cat (VU). South coastal plain of Odisha is the Lacustrine plain of Chilika Lake and the Rushikulya river delta.
