Chilika lake

Chilika Lake is a brackish water lagoon, spread over the Puri, Khurda and Ganjam districts of Odisha state on the east coast of India, at the mouth of the Daya River, flowing into the Bay of Bengal

It is Asia’s largest salt-water lagoon and is separated from the Bay of Bengal by a sandy ridge.

It is the largest wintering ground for migratory birds on the Indian sub-continent. These birds travel great distances; migratory birds probably follow much longer routes than the straight lines, possibly up to 12,000 km, to reach Chilika Lake.

Chilka Lake is designated as a wetland of international importance under the Ramsar Convention. The Ramsar Convention on Wetlands of International Importance especially as Waterfowl Habitat is an international treaty for the conservation and sustainable use of wetlands.

The Irrawaddy dolphin has been found in Chilika lake. It is a euryhaline species of oceanic dolphin found in discontinuous subpopulations near sea coasts and in estuaries and rivers in parts of the Bay of Bengal and Southeast Asia.

Irrawaddy dolphins are classified as ‘Vulnerable’ in the IUCN Red List of Threatened Species.

Exp. IUCN, International Union for Conservation of Nature, helps the world find pragmatic solutions to our most pressing environment and development challenges. It supports scientific research, manages field projects all over the world and brings governments, non-government organizations, United Nations agencies, companies and local communities together to develop and implement policy, laws and best practice. IUCN is the world’s oldest and largest global environmental network - a democratic membership union with more than 1,000 government and NGO member organizations, and almost 11,000 volunteer scientists in more than 160 countries. The IUCN Red List of Threatened Specie is widely recognized as the most comprehensive, objective global approach for evaluating the conservation status of plant and animal species. IUCN also helps countries and communities designate and manage systems of protected areas on land and in the oceans, and this one of IUCN’s main areas of expertise.
