Wetlands Essay -- Nature Wildlife Essays

Wet overturns A clear and widely accepted definition of a wetland has yet to be established. Wetlands are of various types and function, and occur in several(a) locations, and climates which in part make them difficult to define. Many definitions of a wetland film been posed by different groups and individuals, some of the definitions include An area of land that has hydric soil and hydrophytic vegetation, typically flooded for part of the year, and forming a transition zone between aquatic and terrestrial establishments (Brady and Weil, 1999). A wetland is an ecosystem that depends on constant or recurrent, shallow downpour or saturation at or near the surface of the substrate (soil). The minimum essential characteristics of a wetland are recurrent, carry on inundation or saturation at or near the surface and the presence of physical, chemical, and biological features reflective of recurrent, sustained inundation or saturation. (National Research Council, 1995). In general Mitsh and Gosselink (1993) define wetlands as areas that gravel characteristics of both aquatic and terrestrial ecosystems, but are neither. Wetland variety 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 northeastern Carolina Wetlands are classified by the kickoff of moisture and include wetlands sustained by rainfall, wetlands sustained by ground water 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.
