A Ramsar site is a wetland site designated to be of international importance under the Ramsar Convention. The Convention on Wetlands, known as the Ramsar Convention, is an intergovernmental environmental treaty established in 1971 by UNESCO, which came into force in 1975. It provides for national action and international cooperation regarding the conservation of wetlands, and wise sustainable use of their resources. Ramsar identifies wetlands of international importance, especially those providing waterfowl habitat.
Ramsar sites are recorded on the List of Ramsar wetlands of international importance.
Ramsar site criteriaEdit
A wetland can be considered to be internationally important if any of the following nine criteria apply:
- 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."
The 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.
