    Article 2.1: "[Wetlands] may incorporate riparian and coastal zones adjacent to the wetlands, and islands or bodies of marine water deeper than six meters at low tide lying within the wetlands." An ecological definition of a wetland is "an ecosystem that arises when inundation by water produces soils dominated by anaerobic and aerobic processes ...

  3. Freshwater ecosystem - Wikipedia

    en.wikipedia.org/wiki/Freshwater_ecosystem

    Wetlands exist on every continent, except Antarctica. [19] The water in wetlands is either freshwater, brackish or saltwater. [18] The main types of wetland are defined based on the dominant plants and the source of the water. For example, marshes are wetlands dominated by emergent herbaceous vegetation such as reeds, cattails and sedges.

    A wetland is a land area that is saturated with water, either permanently or seasonally, such that it takes on the characteristics of a distinct ecosystem.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.

    The result is a large number of wetland classification systems that each define wetlands and wetland types in their own way. [1] However, many classification systems include four broad categories that most wetlands fall into: marsh , swamp, bog , and fen. [ 1 ]

  6. Bog - Wikipedia

    en.wikipedia.org/wiki/Bog

    The wetland receives most of its water and nutrients from precipitation (ombrotrophic) rather than surface or groundwater (minerotrophic). The wetland is nutrient-poor (oligotrophic). The wetland is strongly acidic (bogs near coastal areas may be less acidic due to sea spray). Because all bogs have peat, they are a type of peatland.

    Difference between swamp and marsh. Swamps and marshes are specific types of wetlands that form along waterbodies containing rich, hydric soils. [7] Marshes are wetlands, continually or frequently flooded by nearby running bodies of water, that are dominated by emergent soft-stem vegetation and herbaceous plants.

  9. Wetlands of the United States - Wikipedia

    en.wikipedia.org/wiki/Wetlands_of_the_United_States

    Deciding if a wetland is a regulated wetland depends on classifying the water in it as "water of the United States" or not. Classifying water as "of the U.S." or "not of the U.S." for purposes of enforcing the Clean Water Act suggests a natural boundary that probably does not exist in nature, and one that was not created regarding air for ...
