A swamp is a forested wetland. [1] Swamps are considered to be transition zones because both land and water play a role in creating this environment. [2] Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater.
Wetlands contribute many ecosystem services that benefit people. These include for example water purification, stabilization of shorelines, storm protection and flood control. In addition, wetlands also process and condense carbon (in processes called carbon fixation and sequestration), and other nutrients and water pollutants.
A wetland (aerial view) Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards. Some examples of these hazards include habitat loss, pollution, and invasive species.
The Wetlands Geodatabase and the Wetlands Mapper, as an Internet discovery portal, provide technological tools that allow the integration of large relational databases with spatial information and map-like displays. The information is made available to an array of federal, state, tribal, and local governments and the public.
Atchafalaya Basin. The wetlands of Louisiana are water-saturated coastal and swamp regions of southern Louisiana, often called "Bayou".. The Louisiana coastal zone stretches from the border of Texas to the Mississippi line [1] and comprises two wetland-dominated ecosystems, the Deltaic Plain of the Mississippi River (unit 1, 2, and 3) and the closely linked Chenier Plain (unit 4).

A large wetland in western Minnesota.. Over the past 200 years, the United States has lost more than 50% of its wetlands. [1] And even with the current focus on wetland conservation, the US is losing about 60,000 acres (240 km 2) of wetlands per year (as of 2004). [2]
In addition, dome swamps are used as areas to treat wastewater. This can cause increased nutrients, organic matter, and minerals to enter the swamp. [10] This can increase aquatic plants, decrease oxygen in the water, and cause declines in native populations. Dome swamps treated with sewage may have higher water levels and litter production. [4]
Mangrove forests, also called mangrove swamps, mangrove thickets or mangals, are productive wetlands that occur in coastal intertidal zones. [1] [2] Mangrove forests grow mainly at tropical and subtropical latitudes because mangrove trees cannot withstand freezing temperatures. There are about 80 different species of mangroves, all of which ...
