wetland Ecosystem where the water table lies close to the surface for much of the year. Wetlands include bogs, marshes, swamps and fens. There are both saltwater and freshwater wetlands. Coastal wetlands are said to contain a greater concentration of flora and fauna than any other ecosystem. They are also ecologically valuable as regulators of flooding and the water cycle. Many of the world's wetlands have been drained for farming or housing.
