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 ...
Palustrine wetlands include any inland wetland that contains ocean-derived salts in concentrations of less than 0.5 parts per thousand, and is non-tidal. [1] The word palustrine comes from the Latin word palus or marsh. [2] Wetlands within this category include inland marshes and swamps as well as bogs, fens, pocosins, tundra and floodplains.
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 .
Determining the boundary of wetland, whether jurisdictional under sections 404 or 10, or not jurisdictional but still meeting the technical definition of a wetland, that is having the soils, vegetation and hydrology criterion met is called a "wetland delineation", and generally is performed by college graduates with natural science or biology ...
Lacustrine wetlands- associated with a lake or other body of fresh water; Palustrine wetlands- freshwater wetlands not associated with a river or lake. The primary purpose of this ecological classification system was to establish consistent terms and definitions used in inventory of wetlands and to provide standard measurements for mapping ...
An aquatic ecosystem is an ecosystem found in and around a body of water, in contrast to land-based terrestrial ecosystems.Aquatic ecosystems contain communities of organisms—aquatic life—that are dependent on each other and on their environment.
The term limnology was coined by François-Alphonse Forel (1841–1912) who established the field with his studies of Lake Geneva.Interest in the discipline rapidly expanded, and in 1922 August Thienemann (a German zoologist) and Einar Naumann (a Swedish botanist) co-founded the International Society of Limnology (SIL, from Societas Internationalis Limnologiae).
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.
