Ramsar Sites Criteria
- Nine criteria identify Wetlands of International Importance
Group A: Representative Wetlands
- Criterion 1: A wetland is internationally important if it's a representative, rare, or unique example of a natural wetland type in a particular biogeographic region.
Group B: Sites for Conserving Biological Diversity
Criteria Based on Species and Ecological Communities
- Criterion 2: A wetland is important if it supports vulnerable, endangered, or critically endangered species or threatened ecological communities.
- Criterion 3: Important if it supports plant and/or animal populations vital to the biological diversity of a specific region.
- Criterion 4: Important if it supports species at critical life stages or provides refuge during adverse conditions.
Specific Criteria Based on Waterbirds
- Criterion 5: Important if it regularly supports at least 20,000 waterbirds.
- Criterion 6: Important if it regularly supports 1% of individuals in one waterbird species or subspecies population.
Specific Criteria Based on Fish
- Criterion 7: Important if it supports a significant proportion of indigenous fish species, life stages, interactions, and/or populations representative of wetland benefits and biodiversity.
- Criterion 8: Important if it's a critical source of food, spawning, nursery, and/or migration path for fish species, within or beyond the wetland.
- Criterion 9 (Other taxa): Important if it supports 1% or more of the individuals in one non-avian wetland-dependent animal species population.
