Wetlands
Rich land habitats saturated by surface or ground water, often abundant in plant and animal life. Marshes or swamps, shallow lakes, coasts, estuaries and flood plains are examples of wetland habitats.
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?
-- Julie, Olathe, KS ...
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.
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.
Wettability ...
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 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: 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.
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.
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 land area that tends to be regularly wet or flooded.
Coastal Wetlands
Climate change will damage coastal wetlands all over the world. Wetlands protect the shore from flooding, and they also provide important habitats for many types of plants and animals.
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 designated by the contracting parties of the Ramsar Convention for inclusion in the list of wetlands of international importance because they meet one or more of the Ramsar criteria.

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.
Wetlands and deepwater habitats with all the following characteristics: 1) situated in a topographic depression or a dammed river channel, 2) less than 30 percent areal coverages by trees, shrubs, persistent emergent vegetation, emergent mosses, ...
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.

Inland freshwater wetlands: Swamps, marshes, and bogs found inland beyond the coastal saltwater wetlands.
Inorganic: Matter other than plant or animal and not containing a combination of carbon, hydrogen, and oxygen, as in living things.
something that is of, like, or originating in wetlands such as marshes, meadows, swamps, or bogs.

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.
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.

Planning, land acquisition, river channel maintenance, wetlands protection, and other regulations all help modify development on floodplains and watersheds to reduce their susceptibility to flood damage.
The storage of water in low areas, such as ponds, and wetlands.
Depth filtration
Treatment process in which the entire filter bed is used to trap insoluble and suspended particles in its voids as water flows through it.
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.
Bottom Land Hardwoods: Forested freshwater wetlands adjacent to rivers in the southeastern United States, especially valuable for wildlife breeding, nesting and habitat.
Design feature in stormwater wetlands that increases flow path length to provide for extended detention and treatment of runoff.

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.
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. (See> wetlands.)

adapted for life in saturated soil conditions; they are critical to sustaining many species of fish and wildlife, including native and migratory birds. They include swamps, marshes, and bogs, and may be either coastal or inland. Coastal wetlands are ...
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.
wetlands An area that is regularly saturated by surface water or groundwater and subsequently is characterized by a prevalence of vegetation that is adapted for life in saturated-soil conditions.
