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.
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 ...
The National Wetlands Inventory (NWI) was established by the United States Fish and Wildlife Service (FWS) to conduct a nationwide inventory of U.S. wetlands to provide biologists and others with information on the distribution and type of wetlands to aid in conservation efforts. To do this, the NWI developed a wetland classification system ...
Coniferous swamps are forested wetlands in which the dominant trees are lowland conifers such as northern white cedar (Thuja occidentalis). The soil in these swamp areas is typically saturated for most of the growing season and is occasionally inundated by seasonal storms or by winter snow melt. The substrate is usually organic in nature and ...
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, nutrients, and ...
The annual range of temperatures in south Florida and the Everglades is rather small (less than 20 °F [11 °C]) – ranging from a monthly mean temperature of around 65 °F (18 °C) in January to 83 °F (28 °C) in July.
By the end of 2008, the Wetlands Geodatabase contained 67 gigabytes of data, including 14.9 million polygonal features. The current status of on-line wetlands data is shown in figure 1. Web accessible geospatial wetlands data can be found at the U.S. Fish and Wildlife website.
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 .
