ABSTRACT
Wetlands are natural ecosystems subject to permanent or periodic inundation or prolonged soil saturation sufficient for the establishment of hydrophytes and/or the development of hydric soils or substrates unless the environmental conditions are such that they prevent them from forming (Cowardin et al. 1979, Tiner 1999). Wetlands provide a range of environmental and socioeconomic benefits. These benefits range from their ability to store floodwaters and improve water quality, to providing habitat for wildlife and supporting biodiversity, to aesthetic values (Mitsch and Gosselink 2000). The loss of wetlands has gained considerable attention over the past few decades. New policies and regulations require improved wetlands management practices and information to promote wetland ecosystems.
