Under-represented wetland types in the Ramsar "List of Wetlands of International Importance"

Mangroves and the Ramsar Convention

For more than 30 years, the Ramsar Convention has been the principal instrument for international cooperation for the conservation and wise use of wetlands. Adopted in Iran in 1971, it was the first of the modern global conservation treaties, and is still the only one dedicated to a particular ecosystem type. Parties to the Convention have committed themselves to designating all of their "suitable wetlands", based upon criteria developed over the years, for inclusion in the List of Wetlands of International Importance (the "Ramsar List") and maintaining their ecological character through management planning for their conservation and sustainable use.

Mangroves

Mangrove swamps are forested intertidal ecosystems that occupy sediment-rich sheltered tropical coastal environments, occurring from about 32ºN (Bermuda) to almost 39ºS (Victoria, Australia). Around two-thirds to three-quarters of tropical coastlines are mangrove-lined. Mangroves carry out critical functions related to the regulation of fresh water, nutrients, and sediment inputs into marine areas. By trapping and stabilizing fine sediments they control the quality of marine coastal waters. They are also exceptionally important in maintaining coastal food webs and populations of animals that live as adults elsewhere and depend upon the mangrove at different stages of their life cycle, such as birds, fish, and crustaceans. Mangroves have an important role in pollution control through their absorptive capacity for organic pollutants and nutrients, and they play an important role in storm protection and coastal stabilization.

A large proportion of the world's mangrove resource has been degraded by unsustainable exploitation practices; habitat destruction; changes in hydrology due to stream diversions for irrigation and dam construction; and pollution, including industrial and sewage effluents and chronic or catastrophic oil spills. Mangroves are particularly vulnerable to oil pollution and increased coastal erosion, sea-level rise, and natural events such as hurricanes, frosts, tsunamis, and human-induced climate change.

Mangroves occur under Marine/Coastal Wetlands: I (Intertidal forested wetlands) in the Ramsar Classification System for Wetland Type.

The Ramsar Secretariat's lead person on mangrove issues is Margarita Astrálaga, astralaga@ramsar.org.
