The Montreux Record is a register of wetland sites on the List of Ramsar wetlands of international importance where changes in ecological character have occurred, are occurring, or are likely to occur as a result of technological developments, pollution or other human interference.
Currently, two wetlands of India are in Montreux record- Keoladeo National Park, Rajasthan and Loktak Lake, Manipur.Further, Chilka lake was placed in the record but was later removed from it.
The Keoladeo National Park is a wetland of international importance (Ramsar site) for migratory waterfowl, where birds migrating down the Central Asian flyway congregate before dispersing to other regions.
Keoladeo was declared a national park in 1982 and then later listed as a World Heritage Site by UNESCO in 1985. It was also known as the breeding ground for the rare and elusive to spot Siberian crane. The park was the only known wintering site of the central population of the critically endangered Siberian Crane, and also serves as a wintering area for other globally threatened species such as the Greater Spotted Eagle and Imperial Eagle.
The site was added to the Montreux Record, 4 July 1990 due to water shortage and an unbalanced grazing regime”. Additionally, the invasive growth of the grass Paspalum distichum has changed the ecological character of large areas of the site, reducing its suitability for certain waterbird species, notably the Siberian crane. The site is artificial and seasonal lagoon.
