As of february 2026, India is home to 98 Ramsar Sites across 28 states and union territories, each recognized for its ecological, hydrological, and biodiversity importance. These wetlands range from massive brackish lagoons to small freshwater marshes that support migratory birds, endangered species, and local livelihoods.
The largest Ramsar Site in India is the Sundarban Wetland in West Bengal (4,230 km²), while the smallest Ramsar Sites include Renuka Lake (Himachal Pradesh) and Vembannur Wetland Complex (Tamil Nadu), each covering less than 1 km².
India’s wetland conservation journey began early, with Chilika Lake (Odisha) and Keoladeo Ghana National Park (Rajasthan) designated as the country’s first Ramsar sites in 1981.
What is a Ramsar Site?
A Ramsar Site is a wetland designated as a Wetland of International Importance under the Ramsar Convention, an international treaty adopted in 1971 at Ramsar, Iran. These sites are recognized for their significant ecological, biological, hydrological, and environmental value at the global level. Ramsar Sites include a wide variety of wetland types such as lakes, rivers, marshes, mangroves, peatlands, floodplains, estuaries, and coastal lagoons.
Features of a Ramsar Site
- Recognized under the Ramsar Convention (1971) as wetlands of international importance
- Includes natural or human-made wetlands, both freshwater and saltwater
- Selected based on scientific criteria, such as biodiversity value, support to endangered species, or importance for migratory birds
- Provides critical habitats for aquatic plants, animals, and waterbirds
- Helps in groundwater recharge, flood control, and water purification
- Acts as a carbon sink, aiding climate change mitigation
- Supports local livelihoods through fishing, agriculture, tourism, and cultural activities
- Promotes the principle of “wise use”, ensuring sustainable utilization without ecological damage
- Encourages national and international cooperation for wetland conservation

Ramsar Sites in India Importance
Ramsar Sites in India are internationally recognized wetlands that play a crucial role in maintaining ecological balance, conserving biodiversity, and supporting livelihoods. These wetlands help regulate climate, sustain water resources, and provide habitat for numerous plant and animal species.
Montreux Record in India
The Montreux Record is a register maintained under the Ramsar Convention that lists wetlands facing ecological threats due to human activities, pollution, or natural changes. Inclusion in this record highlights Ramsar Sites that require urgent conservation attention and restoration measures.
What is the Montreux Record?
- It is a list of Ramsar Sites where ecological changes have occurred, are occurring, or are likely to occur.
- Maintained as part of the Ramsar Convention on Wetlands to monitor vulnerable wetlands.
- Helps governments and conservation agencies prioritize restoration and management efforts.
- Encourages international cooperation and technical support for wetland protection.
- Aims to prevent further degradation and restore ecological balance.
| Ramsar Site | State | Reason | Year |
|---|---|---|---|
| Keoladeo National Park | Rajasthan | Water shortage and grazing pressure | 1990 |
| Loktak Lake | Manipur | Pollution and human intervention | 1993 |
Threats to Ramsar Wetlands in India
Ramsar wetlands in India are under increasing pressure due to rapid urbanization, climate change, and unsustainable human activities. These threats are degrading wetland ecosystems, affecting biodiversity, water security, and the livelihoods dependent on them.
Government Initiatives for Wetland Conservation

- National Plan for Conservation of Aquatic Ecosystems (NPCA) –
A central scheme that focuses on conservation and restoration of lakes and wetlands across India through funding, scientific management, and monitoring. - Wetlands (Conservation and Management) Rules, 2017 –
Provides a legal framework for protection, prohibits harmful activities like encroachment, pollution, and construction near wetlands. - National Wetland Committee (NWC) –
Established to advise the government on wetland conservation policies and oversee implementation of conservation measures. - Integrated Coastal Zone Management (ICZM) Programme –
Protects coastal wetlands, mangroves, and estuaries while promoting sustainable livelihood opportunities. - Amrit Dharohar Scheme (2023) –
Aims to promote conservation of Ramsar Sites through eco-tourism, community participation, and sustainable livelihood generation. - National Biodiversity Action Plan (NBAP) –
Supports conservation of wetland ecosystems and protection of endangered species. - Mangrove Initiative for Shoreline Habitats & Tangible Incomes (MISHTI) –
Focuses on restoration and expansion of mangrove wetlands for coastal protection and livelihood support. - State Wetland Authorities –
Each state establishes dedicated bodies responsible for identification, conservation, and management of wetlands. - Community Participation Programs –
Encourages involvement of local communities, NGOs, and stakeholders in wetland conservation and awareness campaigns. - Use of Remote Sensing and GIS Monitoring –
