An ecological definition of a wetland is "an ecosystem that arises when inundation by water produces soils dominated by anaerobic and aerobic processes, which, in turn, forces the biota, particularly rooted plants, to adapt to flooding". [1] Sometimes a precise legal definition of a wetland is required.
Wetland conservation. 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.
A fen is a type of peat -accumulating wetland fed by mineral-rich ground or surface water. [1][2] It is one of the main types of wetland along with marshes, swamps, and bogs. Bogs and fens, both peat-forming ecosystems, are also known as mires. [2] The unique water chemistry of fens is a result of the ground or surface water input.
The beaver is a keystone species, increasing biodiversity in its territory through creation of ponds and wetlands. [1] [2] As wetlands are formed and riparian habitats enlarged, aquatic plants colonize newly available watery habitat. Insect, invertebrate, fish, mammal, and bird diversities are also expanded. [3]
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).

Freshwater ecosystem. Freshwater ecosystems are a subset of Earth's aquatic ecosystems. They include lakes, ponds, rivers, streams, springs, bogs, and wetlands. [1] They can be contrasted with marine ecosystems, which have a larger salt content. Freshwater habitats can be classified by different factors, including temperature, light penetration ...
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] However, from 1998 to 2004 the United States managed a net gain of 191,750 acres (776.0 km 2) of wetlands (mostly freshwater). [2] The past several decades have seen an increasing number of laws and ...
Children celebrating World Wetlands Day. World Wetlands Day is an environmentally related celebration which dates back to the year 1971 when several environmentalists gathered to reaffirm protection and love for wetlands, [1] which are water ecosystems containing plant life and other organisms that bring ecological health in abundance to not only water bodies but environments as a whole.
