- supports vulnerable, endangered, or critically endangered species; or threatened ecological communities.
- supports populations of plant and/or animal species important for maintaining the biological diversity of a particular biogeographic region.
- supports plant and/or animal species at a critical stage in their life cycles or provides refuge during adverse conditions.
- regularly supports 20,000 or more water birds.
- regularly supports 1% of the individuals in a population of one species or subspecies of water birds.
- supports a significant proportion of indigenous fish subspecies.

The Montreux Record:
- The Montreux Record is a register of wetland sites on the List of Wetlands of International Importance where changes in ecological character have occurred, are occurring, or are likely to occur as a result of technological developments, pollution or other human interference.
- It is maintained as part of the Ramsar List.
- From India, Keoladeo National Park (Rajasthan) and Loktak Lake (Manipur) are under Montreux record.
