Conservation Efforts
Due to its ecological importance, Chilka Lake has been designated as a Ramsar site, which is a wetland of international importance. The lake is also protected as a wildlife sanctuary and a national park. Conservation efforts aim to preserve the biodiversity of the lake and maintain its ecological balance.

Overall, Chilka Lake is not only the largest saline water lake in India but also a significant ecosystem that supports a diverse range of flora and fauna. Its conservation is essential to maintain the ecological balance and sustain the livelihoods of the local communities.
