The Haiderpur Wetland abutting the Madhya Ganga barrage, about 10 km from Bijnor in western Uttar Pradesh, has been recognised under the 1971 Ramsar Convention on Wetlands. Uttar Pradesh is now home to 9 Ramsar wetlands. The wetland has also been identified under Namami Gange, a central flagship, as a model wetland along the Ganga. With this, there are now a total of 47 such designated areas in the country.
The Site supports more than 25,000 waterbirds, serves as a breeding site for the near-threatened Indian grassbird and provides refuge to the northern subspecies population of the vulnerable swamp deer during its seasonal flood-driven migration. The Site also regularly supports more than 1% of the population of greylag goose and bar-headed goose.
