Ramsar site

A Ramsar site is a wetland site designated to be of international importance under the Ramsar Convention,^[1] also known as "The Convention on Wetlands", an international environmental treaty signed on 2 February 1971 in Ramsar, Iran, under the auspices of UNESCO. It came into force on 21 December 1975, when it was ratified by a sufficient number of nations. It provides for national action and international cooperation regarding the conservation of wetlands, and wise sustainable use of their resources.^[1] Ramsar identifies wetlands of international importance, especially those providing waterfowl habitat.

As of November 2023^[update], there are 2,500 Ramsar sites around the world, protecting 257,106,360 hectares (635,323,700 acres), and 172 national governments are participating.^[1]
