Wetlands Essay -- Nature Wildlife Essays
Wetlands A clear and widely accept definition of a pissedland has yet to be established. Wetlands atomic number 18 of various types and function, and emit in diverse locations, and climates which in part make them difficult to nail down. galore(postnominal) definitions of a wetland have been posed by different groups and individuals, some of the definitions complicate An area of land that has hydric soil and hydrophytic vegetation, typic wholey inundate for part of the year, and forming a transition zone between aquatic and routine systems (Brady and Weil, 1999). A wetland is an ecosystem that depends on constant or recurrent, shallow inundation or chroma at or near the surface of the substrate (soil). The borderline essential characteristics of a wetland are recurrent, sustained inundation or saturation at or near the surface and the presence of physical, chemical, and biological features thoughtful of recurrent, sustained inundation or saturation. (National Research Council, 1995). In general Mitsh and Gosselink (1993) define wetlands as areas that have characteristics of both aquatic and terrestrial ecosystems, but are neither. Wetland classification systems are not used consistently by all groups of people, consequently wetland classification differences occur regionally. Wetlands classifications include bogs, fens, swamps and flood plain forests, marshes, and wet meadows. In North Carolina Wetlands are classified by the solution of wet and include wetlands sustained by rainfall, wetlands sustained by ground piddle discharge, wetlands sustained by ground water and surface water, wetlands on rivers and lakes, and wetlands on the ocean. This classification system has subcategories under each type of wetland (Vepra... ...npoint pollution. J. Soil & pee Conserv. 4087-97.Mitsch, W.J. 1993.
