Ramsar sites are asked in two forms — a wetland is named and you supply the state, or a fact about the Convention is asked directly. One of those is stable and one is not. The site-to-state pairs and the Convention facts never change; the total number of Ramsar sites in India changes almost every year, and that single figure is the most common outdated fact in this topic. This post separates the two, gives the sites state by state, and ends with previous year questions.
Key Points (Quick Revision)
- Ramsar Convention signed in 1971 at Ramsar, Iran; came into force 1975
- India's first two Ramsar sites (1981) — Chilika Lake and Keoladeo National Park
- World Wetlands Day — 2 February
- Montreux Record — sites under ecological threat; India's entries are Keoladeo and Loktak
- 🔴 The total number of Indian Ramsar sites keeps rising — verify it before any exam
1. The Ramsar Convention — the facts that never change
| Fact | Answer |
|---|---|
| Full name | Convention on Wetlands of International Importance |
| Signed at | Ramsar, a city in Iran |
| Year signed | 1971; entered into force in 1975 |
| India joined | 1982 |
| India's first sites | Chilika Lake, Odisha and Keoladeo National Park, Rajasthan, both in 1981 |
| World Wetlands Day | 2 February, marking the signing date |
| Montreux Record | A register of Ramsar sites facing ecological change; India's listed sites are Keoladeo and Loktak |
| Secretariat | Gland, Switzerland |
Two of these are asked far more than the rest. Ramsar is a city in Iran, not an acronym — a surprising number of candidates get that wrong. And Chilika and Keoladeo were India's first two sites, both designated in 1981, a year before India formally joined the Convention.
The Montreux Record is worth keeping separate. It lists sites where ecological character has changed or is likely to change. India has two entries — Keoladeo in Rajasthan and Loktak in Manipur. Chilika was placed on the Record and was later removed after restoration work, which is itself a question.
2. Ramsar sites by state — the ones exams ask about
| Wetland | State or UT | Note |
|---|---|---|
| Chilika Lake | Odisha | India's largest brackish-water lagoon; among the first two sites |
| Keoladeo National Park | Rajasthan | Bharatpur; also a UNESCO World Heritage Site |
| Sambhar Lake | Rajasthan | India's largest inland salt lake |
| Loktak Lake | Manipur | Famous for its floating phumdis and Keibul Lamjao National Park |
| Wular Lake | Jammu and Kashmir | One of Asia's largest freshwater lakes |
| Hokera and Surinsar-Mansar | Jammu and Kashmir | Frequently asked together with Wular |
| Tsomoriri and Tso Kar | Ladakh | High-altitude wetlands |
| Harike and Kanjli | Punjab | Harike is at the Beas-Sutlej confluence |
| Ropar | Punjab | On the Sutlej |
| Sultanpur and Bhindawas | Haryana | Haryana's first Ramsar sites |
| Sundarban Wetland | West Bengal | India's largest Ramsar site by area |
| Bhoj Wetland | Madhya Pradesh | At Bhopal |
| Nalsarovar | Gujarat | Bird sanctuary |
| Point Calimere and Pichavaram | Tamil Nadu | Tamil Nadu has the largest number of sites among the states |
| Vembanad-Kol, Ashtamudi, Sasthamkotta | Kerala | Sasthamkotta is Kerala's largest freshwater lake |
| Kolleru Lake | Andhra Pradesh | Between the Krishna and Godavari deltas |
| Deepor Beel | Assam | Assam's Ramsar site near Guwahati |
| Renuka | Himachal Pradesh | India's smallest Ramsar site by area |
| Upper Ganga River stretch | Uttar Pradesh | Brijghat to Narora |
| Nandur Madhmeshwar | Maharashtra | Maharashtra's first Ramsar site |
The superlatives in this table are asked more often than the sites themselves. Sundarban is the largest by area, Renuka the smallest, Chilika the largest brackish lagoon, and Sambhar the largest inland salt lake. Those four answer a whole family of questions.
Note also that Tamil Nadu holds the largest number of Ramsar sites among the states, which is a recurring question — though since designations are added regularly, treat state-wise counts as a figure to check rather than to memorise.
3. Why wetlands matter — the concepts asked alongside
Questions increasingly ask about function rather than location, so these are worth a separate look.
- Wetlands are called the kidneys of the landscape, because they filter pollutants and sediment from water passing through them. That phrase is asked directly.
- Groundwater recharge and flood control. Wetlands absorb and slowly release water, moderating both floods and droughts.
- Carbon storage. Peatlands and mangroves store carbon at high densities, which is why they appear in climate questions.
- Biodiversity and migratory birds. Indian wetlands lie on the Central Asian Flyway, which is the term questions use for the migratory route.
- Livelihoods from fishing, agriculture and tourism.
Two Indian frameworks are asked with this topic. The Wetlands (Conservation and Management) Rules, 2017 govern the regulation of wetlands in India, and the National Plan for Conservation of Aquatic Ecosystems is the scheme under which wetlands and lakes are conserved. The Amrit Dharohar initiative, announced to promote conservation and eco-tourism at Ramsar sites, is a more recent addition.
4. Wetland types and terms
| Term | What it means |
|---|---|
| Marsh | Wetland dominated by herbaceous plants rather than trees |
| Swamp | Wetland dominated by trees and woody plants |
| Bog | Peat-forming wetland fed mainly by rainwater, acidic |
| Fen | Peat-forming wetland fed by groundwater, less acidic than a bog |
| Mangrove | Coastal wetland of salt-tolerant trees; Sundarban is the classic Indian example |
| Estuary | Where a river meets the sea and fresh water mixes with salt water |
| Lagoon | Shallow water body separated from the sea by a barrier; Chilika and Pulicat |
| Phumdi | Floating mass of vegetation and soil, characteristic of Loktak Lake |
Bog against fen and marsh against swamp are the two pairs papers use as options against each other. The distinctions are simple once stated: bogs are rain-fed and fens groundwater-fed; marshes have herbaceous plants and swamps have trees.
Phumdi is worth learning on its own, because it is the one term tied to a specific Indian site — the floating islands of Loktak Lake, on which Keibul Lamjao, the world's only floating national park, sits.

6. How to revise this topic
Separate the fixed facts from the moving ones before you start, because this is the topic where old notes most often go wrong.
Fixed: the Convention year and place, World Wetlands Day, India's first two sites, the Montreux Record entries, every site-to-state pair, and the four superlatives. Learn these once and they keep working.
Moving: the total number of Ramsar sites in India, the state-wise counts, and which state currently has the most. India has added sites steadily and in batches, so a figure printed in a book two years old is almost certainly wrong now. Check the current total from an official source before any examination rather than memorising it here.
Beyond that, revise the sites state-wise rather than alphabetically. Questions give the wetland and ask for the state far more often than the reverse, and clustering by state means one blank does not take the whole region with it. Kashmir, Punjab, Rajasthan, Kerala and Tamil Nadu carry the largest clusters.
Finally, keep the eight wetland-type terms on their own card. Bog against fen and marsh against swamp are asked as definition questions, entirely separately from the site list.
7. Frequently Asked Questions
What is the Ramsar Convention?
The Convention on Wetlands of International Importance, signed in 1971 at Ramsar, a city in Iran, and in force since 1975. It provides a framework for the conservation and wise use of wetlands. India became a party in 1982.
Which were India's first Ramsar sites?
Chilika Lake in Odisha and Keoladeo National Park in Rajasthan, both designated in 1981. Keoladeo, at Bharatpur, is also a UNESCO World Heritage Site, which is asked as a separate fact.
How many Ramsar sites does India have?
The number has risen steadily, often in batches, so any figure quoted in study material dates quickly. The site names and their states are stable; the total is not. Check the current count from an official source before an examination rather than relying on a printed list.
What is the Montreux Record?
A register of Ramsar sites where the ecological character has changed or is likely to change. India's listed sites are Keoladeo and Loktak. Chilika was on the Record earlier and was removed after restoration work, which is itself a favourite question.
What are phumdis?
Floating masses of vegetation, soil and organic matter found on Loktak Lake in Manipur. Keibul Lamjao National Park, the world's only floating national park and home to the sangai deer, sits on them.
