Swamp

swampsswamplandsloughs
The main wetland types are swamp, marsh, bog, and fen; sub-types include mangrove forest, carr, pocosin, floodplains, mire, vernal pool, sink, and many others. The duration of flooding or prolonged soil saturation by groundwater determines whether the resulting wetland has aquatic, marsh or swamp vegetation.
A swamp is a wetland that is forested.

Bog

The main wetland types are swamp, marsh, bog, and fen; sub-types include mangrove forest, carr, pocosin, floodplains, mire, vernal pool, sink, and many others. When peat accumulates, bogs and fens arise.
A bog or bogland is a wetland that accumulates peat, a deposit of dead plant material—often mosses, and in a majority of cases, sphagnum moss.

Marsh

The main wetland types are swamp, marsh, bog, and fen; sub-types include mangrove forest, carr, pocosin, floodplains, mire, vernal pool, sink, and many others. The duration of flooding or prolonged soil saturation by groundwater determines whether the resulting wetland has aquatic, marsh or swamp vegetation.
A marsh is a wetland that is dominated by herbaceous rather than woody plant species.

Fen

A fen is one of the main types of Wetlands, the others being grassy marshes, forested swamps, and peaty bogs.

Vernal pool

vernal poolstemporary poolephemeral pool
The main wetland types are swamp, marsh, bog, and fen; sub-types include mangrove forest, carr, pocosin, floodplains, mire, vernal pool, sink, and many others.
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.

Hydric soil

hydricanaerobic soilmuck
The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric soil.
Hydric soil is soil which is permanently or seasonally saturated by water, resulting in anaerobic conditions, as found in wetlands.

Pocosin

pocosinsPoquoson (geographic term)shrub bog
The main wetland types are swamp, marsh, bog, and fen; sub-types include mangrove forest, carr, pocosin, floodplains, mire, vernal pool, sink, and many others.
Pocosin is a type of palustrine wetland with deep, acidic, sandy, peat soils.

Pantanal

Gran PantanalPantanal biomePantanal Boliviano
The largest wetlands include the Amazon River basin, the West Siberian Plain, the Pantanal in South America, and the Sundarbans in the Ganges-Brahmaputra delta.
The Pantanal is a natural region encompassing the world's largest tropical wetland area.

Wetland conservation

conservationconservation of wetlandsProtected Wetlands Habitat
Methods for rapidly assessing these functions, wetland ecological health, and general wetland condition have been developed in many regions and have contributed to wetland conservation partly by raising public awareness of the functions and the ecosystem services some wetlands provide.
Wetlands cover at least six per cent of the Earth and have become a focal issue for conservation due to the ecosystem services they provide.

Constructed wetland

constructed wetlandsartificial wetlandwetlands
Constructed wetlands are used to treat municipal and industrial wastewater as well as stormwater runoff.
A constructed wetland (CW) is an artificial wetland to treat municipal or industrial wastewater, greywater or stormwater runoff.

Body of water

bodies of waterwater bodieswaterbodies
Wetlands have unique characteristics: they are generally distinguished from other water bodies or landforms based on their water level and on the types of plants that live within them.
The term most often refers to oceans, seas, and lakes, but it includes smaller pools of water such as ponds, wetlands, or more rarely, puddles.

Ramsar Convention

RamsarRamsar siteRamsar Convention on Wetlands
United Nations Millennium Ecosystem Assessment and Ramsar Convention described wetlands as a whole to be of biosphere significance and societal importance in the following areas, for example:
The Ramsar Convention on Wetlands of International Importance especially as Waterfowl Habitat is an international treaty for the conservation and sustainable use of wetlands.

Clean Water Act

Federal Water Pollution Control ActNational Pollutant Discharge Elimination SystemNPDES
This definition has been used in the enforcement of the Clean Water Act.
Its objective is to restore and maintain the chemical, physical, and biological integrity of the nation's waters; recognizing the responsibilities of the states in addressing pollution and providing assistance to states to do so, including funding for publicly owned treatment works for the improvement of wastewater treatment; and maintaining the integrity of wetlands.

Peat

turfpeat cuttingpeat extraction
When peat accumulates, bogs and fens arise.
Peat forms in wetland conditions, where flooding or stagnant water obstructs the flow of oxygen from the atmosphere, slowing the rate of decomposition.

Palustrine wetland

palustrine
Based on hydrology, wetlands can be categorized as riverine (associated with streams), lacustrine (associated with lakes and reservoirs), and palustrine (isolated).
Palustrine wetlands include any inland wetland that lacks flowing water, contains ocean-derived salts in concentrations of less than 0.5 parts per thousand, and is non-tidal.

Groundwater

ground waterunderground waterpore water
The duration of flooding or prolonged soil saturation by groundwater determines whether the resulting wetland has aquatic, marsh or swamp vegetation.
Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands.

Ecosystem

A wetland is a distinct ecosystem that is flooded by water, either permanently or seasonally, where oxygen-free processes prevail.
Wet soils tend to become deficient in oxygen (this is especially true in wetlands), which slows microbial growth.

Ecotone

ecotonesecotonaltransition
Wetlands have also been described as ecotones, providing a transition between dry land and water bodies.
Most wetlands are ecotones.

Peltandra virginica

Floating water plants or floating vegetation is usually small, like arrow arum (Peltandra virginica).
It is widely distributed in wetlands in the eastern United States, as well as in Quebec, Ontario, and Cuba.

Everglades

Florida Evergladesthe EvergladesGlades
Alligators occur in fresh water along with the fresh water species of the crocodile.The Florida Everglades is the only place in the world where both crocodiles and alligators coexist.
The Everglades is a natural region of tropical wetlands in the southern portion of the U.S. state of Florida, comprising the southern half of a large drainage basin within the neotropic ecozone.

Saltwater crocodile

The saltwater crocodile inhabits estuaries and mangroves and can be seen in the coastline bordering the Great Barrier Reef in Australia.
The saltwater crocodile (Crocodylus porosus) is a crocodilian native to saltwater habitats and brackish wetlands from India's east coast across Southeast Asia and the Sundaic region to northern Australia and Micronesia.

Crocodile

Reptiles such as alligators and crocodiles are common in wetlands of some regions.
All crocodiles are semiaquatic and tend to congregate in freshwater habitats such as rivers, lakes, wetlands and sometimes in brackish water and saltwater.

Swamp rabbit

Sylvilagus aquaticus
Mammals include numerous small and medium-sized species such as vole s, bat s, and platypus in addition to large herbivorous and apex species such as the beaver, coypu, swamp rabbit, Florida panther, and moose.
The swamp rabbit (Sylvilagus aquaticus), or swamp hare, is a large cottontail rabbit found in the swamps and wetlands of the southern United States.
