How are Wetlands Protected in the U.S. & Canada?
Dear EarthTalk: What defines a "wetland" and how are wetlands protected in the U.S. and Canada from destruction by development and other threats?

wetland - land (marshes or swamps) saturated with water constantly or recurrently; conducive to wide biodiversity.
wilderness - land remaining in basically wild (i.e., undisturbed) condition, with few if any traces of human activities.
Wetlands. Lands transitional between terrestrial and aquatic systems where the water table is usually at or near the surface or the land is covered by shallow water.
Wetland
Any area in which the water table stands near, at, or above the land surface for at least part of the year. Such areas are characterized by plants that are adapted to wet soil conditions.
Wetlands: An area that is saturated by surface or ground water with vegetation adapted for life under those soil conditions, as swamps, bogs, fens, marshes, and estuaries.
Wetland
An area that is regularly saturated by surface water or groundwater and is characterized by a prevalence of vegetation that is adapted for life in saturated soil conditions (e.g., swamps, bogs, fens, marshes, and estuaries).
WETLANDS: Areas with standing water or a high water table that under normal circumstances support vegetation typically adapted to saturated soil conditions; generally includes swamps, marshes, ...
Wetlands: Lands where water saturation is the dominant factor that determines the nature of soil development and the types of plant and animal communities living in the surrounding environment.
Wetland: An area of land that is periodically saturated with water, which influences the types of plants and animals that can live there. Wetlands include swamps, marshes, bogs, and other similar areas.
Wetlands: areas that are regularly wet or flooded and have a water table that stands at or above the land surface for at least part of the year.
Wetland
An area that is regularly saturated by surface or groundwater and, under normal circumstances, capable of supporting vegetation typically adapted for life in saturated soil conditions; ...
Wetlands are areas occasionally or always covered with shallow fresh or salt water.
World Trade Organisation (WTO). The international body set up as part of the General Agreement on Tariffs and Trade in order to promote free trade. More ...
wetlands : Any number of tidal and nontidal areas characterized by saturated or nearly saturated soils most of the year that form an interface between terrestrial (land-based) and aquatic environments; ...
wetlands: any land area that tends to be regularly wet or flooded.

Definition (english only)
Areas that are inundated by surface or ground water with frequency sufficient to support a prevalence of vegetative or aquatic life that requires saturated or seasonally saturated soil conditions for growth ...
Wetlands
Areas that are soaked or flooded by surface or ground water frequently enough or for sufficient duration to support plants, birds, animals, and aquatic life.
Wetlands: Habitats flooded with shallow water all or part of the year. Can be identified by unique plants which have adapted to oxygen-deficient (anaerobic) soils. Wetlands influence stream flows and water quality.

Wetland Semi-aquatic land, that is land that is either inundated or saturated by water for varying periods of time during each year, and that supports aquatic vegetation which is specifically adapted for saturated soil conditions.

Wetland and deepwater habitats contained within a channel with two exceptions: 1) wetlands dominated by trees, shrubs, persistent emergent plants, emergent mossess, or lichens, and 2) habitat with water containing ocean-derived salts in excess of 5 ...
Managed wetlands used for the treatment of wastewaters; commonly planted with phragmites australis and other species to facilitate BOD removal below soil surface ...
Forested wetlands are areas that require special attention to balancing the three factors discussed above.
These pinelands are managed for red cockaded woodpecker habitat.
constructed wetland An artificial wetland system designed to remove waterborne contaminants through natural treatment processes.
wetland transitional zones between dry land and deep water where saturation with water is the dominant factor determining the nature of soil development and the types of plant and animal communities living in the soil and on surface.
Fen: A type of wetland that accumulates peat deposits. Fens are less acidic than bogs, deriving most of their water from groundwater rich in calcium and magnesium.
marsh A type of wetland that does not accumulate appreciable peat deposits and is dominated by herbacious vegetation. Marshes may be fresh- or saltwater, tidal or nontidal.
Land Reclamation Land reclamation can refer to the process of creating new, dry land on the seabed--modifying wetlands or waterways to convert them into usable land.
peat: Peat develops in wetlands from built-up rotting vegetable matter.
permafrost: Permafrost is the layer of soil just below the surface that stays frozen year-round, mostly in the polar regions of the earth.
Swamp: A type of wetland dominated by woody vegetation but without appreciable peat deposits. Swamps may be fresh or salt water and tidal or non-tidal. (See: wetlands.) ...
This is a new way of dealing with waste and pollution and will probably be developed more extensively in future. Wetlands are a natural bio-remediation process which filter out most pollutants from water.
For further information on wetlands: ...
There are many types of pollutants, both human-made and natural, that wash into our lakes, rivers, streams, wetlands, and coastal waters and percolated into our groundwater every year.
The principal natural phenomena that contribute acid-producing gases to the atmosphere are emissions from volcanoes and those from biological processes that occur on the land, in wetlands, and in the oceans.
Methane is produced naturally, including from volcanoes, wetlands, termites and the ocean, and by human activity, including from flatulent livestock and the decomposition of organic matter buried in landfill.
Water that is collected on the ground or in a stream, river, lake, wetland or ocean.

A federal permit authorized by the Clean Water Act, Title IV, which is required for discharge of pollutants to navigable waters of the United States, which includes any discharge to surface waters-lakes, streams, rivers, bays, the ocean, wetlands, ...
near-shore ocean waters, where tidal action and river flow mix fresh and salt water. Such areas include bays, mouths of rivers, salt marshes, and lagoons. These brackish water ecosystems shelter and feed marine life, birds, and wildlife. See Wetlands.
Recently, protections for non-navigable streams and seasonal wetlands have suffered setbacks. We can and should push for further improvement on water issues.
As for the proposed diesel regulations, this appears to be the only item without a big But.
watershed The area drained by a given stream. water table The upper level of groundwater. wetlands Areas such as tidal flats or swamps covered by shallow water, or where the water table is at or near the surface.
