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 October 2024[update], there are 2,521 Ramsar sites around the world, protecting 257,317,367 hectares (635,845,060 acres), and 172 national governments are participating.[1]

Ramsar site criteria
editA wetland can be considered internationally important if any of the following nine criteria apply:[3]
- Criterion 1: "it contains a representative, rare, or unique example of a natural or near-natural wetland type found within the appropriate biogeographic region."
- Criterion 2: "it supports vulnerable, endangered, or critically endangered species or threatened ecological communities."
- Criterion 3: "it supports populations of plant and/or animal species important for maintaining the biological diversity of a particular biogeographic region."
- Criterion 4: "it supports plant and/or animal species at a critical stage in their life cycles, or provides refuge during adverse conditions."
- Criterion 5: "it regularly supports 20,000 or more waterbirds."
- Criterion 6: "it regularly supports 1% of the individuals in a population of one species or subspecies of waterbird."
- Criterion 7: "it supports a significant proportion of indigenous fish subspecies, species or families, life-history stages, species interactions and/or populations that are representative of wetland benefits and/or values and thereby contributes to global biological diversity."
- Criterion 8: "it is an important source of food for fishes, spawning ground, nursery and/or migration path on which fish stocks, either within the wetland or elsewhere, depend."
- Criterion 9: "it regularly supports 1% of the individuals in a population of one species or subspecies of wetland-dependent non-avian animal species."
Classification
editThe Ramsar Classification System for Wetland Type is a wetland classification developed within the Ramsar Convention intended as a means for fast identification of the main types of wetlands for the purposes of the Convention.[4]
Marine/coastal wetlands
edit- Saline water:
- Permanent:
- (A) Permanent shallow marine waters: Less than 6m deep at low tide; including sea bays and straits
- (B) Marine subtidal aquatic beds: Underwater vegetation; including kelp beds and sea grass beds, and tropical marine meadows
- (C) Coral reefs
- Shores:
- (D) Rocky marine shores
- (E) Sand, shingle or pebble shores
- Permanent:
- Saline or brackish water:
- Intertidal:
- (G) Intertidal mud, sand or salt flats
- (H) Intertidal marshes
- (I) Intertidal forested wetlands
- Lagoons:
- (J) Coastal brackish/saline lagoons
- Estuarine waters:
- (F) Estuarine waters
- Intertidal:
- Saline, brackish, or fresh water:
- Subterranean:
- (Zk(a)) Karst and other subterranean hydrological systems
