Soil-Vegetation Correlations in the Pocosins of Croatan National Forest, North Carolina.
Abstract
The U.S. Fish and Wildlife Service has accepted responsibility for the development of inventory technologies and methodologies for designation and classification of wetlands. The Service's definition of wetlands follows Cowardin et al. (1979): transitional between terrestrial and aquatic systems where the water table is usually at or near the surface or the land is covered by shallow water... wetlands must have one or more of the following three attributes: (1) at least periodically, the land supports predominantly hydrophytes; (2) the substrate is predominantly undrained hydric soil; and (3) the substrate is nonsoil and is saturated with water or covered by shallow water at some time during the growing season of each year.... The upland limit of wetland is designated as: (1) the boundary between land with predominantly mesophytic and xerophytic cover; (2) the boundary between soil that is predominantly hydric and soil that is predominantly nonhydric; or (3) in the case of wetlands without vegetation or soil, the boundary between land that is flooded or saturated at some time each year and land that is not.
