Ramsar Sites in India: Map, State-wise List & Key Facts [2025]

Ramsar Sites in India are wetlands of international importance designated under the Ramsar Convention, an international treaty for the conservation and sustainable use of wetlands.

As of 2025, India has 91 Ramsar Sites, the third highest in the world, following the United Kingdom (176) and Mexico (144). These sites span a variety of wetland ecosystems, including freshwater lakes, marshes, mangroves, estuaries, and even high-altitude lakes.

This article provides a comprehensive overview of Ramsar Sites in India, including a PDF map, state-wise list, and key facts—useful for competitive exams like UPSC, SSC, and State PCS.

Newly Added Ramsar Sites in India

In June 2025, two new sites were added to the list of Ramsar Sites in India, bringing the total number to 91. These sites are:

1. Khichan (Rajasthan)
2. Menar (Rajasthan)

Previously, in February 2025, the following four sites were designated as Ramsar sites:

1. Sakkarakottai Bird Sanctuary (Tamil Nadu)
2. Therthangal Bird Sanctuary (Tamil Nadu)
3. Khecheopalri Wetland (Sikkim)
4. Udhwa Lake (Jharkhand)

With these additions, both Sikkim and Jharkhand received their first Ramsar site designations, while the total number of Ramsar sites in Tamil Nadu rose to 20 — the highest in the country, well ahead of second-placed Uttar Pradesh, which has 10 sites.

Ramsar Convention

• The Ramsar Convention on Wetlands is an international treaty for “the conservation and sustainable use of wetlands.”
• It is also known as the Convention on Wetlands.
• The convention is named after the city of Ramsar in Iran, where it was signed on February 2, 1971. Since then, February 2 is celebrated annually as World Wetlands Day.
• There are 172 parties to the Ramsar Convention (COP).
• A site can be declared as a Ramsar Site if it meets any one of the nine criteria set under the Ramsar Convention.
• When a country accedes to the Ramsar Convention, it must designate at least one wetland as a Wetland of International Importance.
• The inclusion of a “Ramsar Site” in the List reflects the government’s commitment to maintaining its ecological character.
• There are over 2,400 Ramsar Sites worldwide, covering 2.5 million sq km across the territories of 172 Ramsar Contracting Parties.
• The world’s first Ramsar Site was the Cobourg Peninsula in Australia, designated in 1974.
• The countries with the most Ramsar Sites are the United Kingdom (176) and Mexico (144).
• Bolivia has the largest area under Ramsar protection.

Montreux Record

The Montreux Record is a register within the Ramsar Convention on Wetlands that identifies wetlands of international importance facing threats or ecological changes.

These are sites where ecological changes have occurred, are occurring, or may occur due to technological developments, pollution, or other human interference. They remain part of the Ramsar List (i.e., inclusion in the Montreux Record does not exclude them from the Ramsar List) and are prioritized for conservation efforts.

Two Ramsar sites from India are currently on the Montreux Record:

1. Loktak Lake (Manipur)
2. Keoladeo National Park (Rajasthan)

Chilika Lake (Odisha) was removed from the Montreux Record in 2002 due to successful restoration efforts.
