A wetland is a distinct semi-aquatic ecosystem whose groundcovers are flooded or saturated in water, either permanently, for years or decades, or only seasonally for a shorter periods. Flooding results in oxygen-poor (anoxic) processes taking place, especially in the soils. Wetlands form a transitional zone between waterbodies and dry lands, and are different from other terrestrial or aquatic ecosystems due to their vegetation's roots having adapted to oxygen-poor waterlogged soils. They are considered among the most biologically diverse of all ecosystems, serving as habitats to a wide range of aquatic and semi-aquatic plants and animals, with often improved water quality by the plants removing excess nutrients such as nitrates and phosphates.

Classification of wetlands has been a problematical task, with the commonly accepted definition of what constitutes a wetland being among the major difficulties. A number of national wetland classifications exist.

The Port Phillip Bay and Bellarine Peninsula Ramsar Site is one of the Australian sites listed under the Ramsar Convention as a wetland of international importance. It was designated on 15 December 1982, and is listed as Ramsar Site No.266. Much of the site is also part of either the Swan Bay and Port Phillip Bay Islands Important Bird Area or the Werribee and Avalon Important Bird Area, identified as such by BirdLife International because of their importance for wetland and waterbirds as well as for orange-bellied parrots. It comprises some six disjunct, largely coastal, areas of land, totalling 229 km2, along the western shore of Port Phillip and on the Bellarine Peninsula, in the state of Victoria. Wetland types protected include shallow marine waters, estuaries, freshwater lakes, seasonal swamps, intertidal mudflats and seagrass beds.
The Edithvale–Seaford Wetlands is a collection of principally freshwater swamps and marshlands totalling 261 hectares in southeastern Melbourne, Australia, about 30 km (19 mi) southeast of Melbourne CBD.

The Southern Ewaso Ng'iro is a river in the Great Rift Valley in Kenya. It plays an important role in the ecology of Lake Natron, the main regular breeding site for near-threatened lesser flamingos. Changes to land use in the river's headwaters or in the marshes before the river enters the lake could have a serious impact on this species.
