Wetlands generally include swamps, marshes, bogs, and similar areas." [1] [2] [3] Wetlands can be valued in terms of their contributions to ecological, economic and social systems. Wetlands service these systems through multiple processes including water filtration, water storage and biological productivity. [4]

Wetlands exist on every continent, except Antarctica. [19] The water in wetlands is either freshwater, brackish or saltwater. [18] The main types of wetland are defined based on the dominant plants and the source of the water. For example, marshes are wetlands dominated by emergent herbaceous vegetation such as reeds, cattails and sedges.
Difference between swamp and marsh. Swamps and marshes are specific types of wetlands that form along waterbodies containing rich, hydric soils. [7] Marshes are wetlands, continually or frequently flooded by nearby running bodies of water, that are dominated by emergent soft-stem vegetation and herbaceous plants.
Vernal pools, also called vernal ponds or ephemeral pools, are temporary pools of water that provide habitat for distinctive plants and animals.They are considered to be a distinctive type of wetland usually devoid of fish, and thus allow the safe development of natal amphibian and insect species unable to withstand competition or predation by fish.
The Ramsar Convention (full title: Convention on Wetlands of International Importance, especially as Waterfowl Habitat), is an international treaty designed to address global concerns regarding wetland loss and degradation. The primary purposes of the treaty are to list wetlands of international importance and to promote their wise use, with ...
Wetlands are not only freshwater habitats and systems, as there are salt marshes and bogs that support different species. [7] Carolina Bays (also known as pocosins, meaning "swamp on a hill") are a unique form of wetland predominately found in the Carolinas, with a few being found outside of the Carolinas along the East Coast of the United ...
Tropical wet forests are characterized by the complex, physical structure of the ecosystem. There are many layers of plant communities, though they are rarely visible from the ground. Shrubs and creepers fill the forest floor with saplings dispersed throughout. Large trees hold their full crowns in the canopy, prohibiting sunlight from plants ...
