National Wetland Plant List
This National Wetland Plant List represents a national effort led by the U.S. Army Corps of Engineers to. The NWPL (and the information implied by its wetland plant species status ratings) is used extensively in wetland delineation, wetland restoration and research, and the development of compensatory mitigation goals, as well as in providing general botanical information about wetland plants. The NWPL covers all 50 U.S. states, the District of Columbia, and the U.S. Caribbean and Pacific islands that are considered to be territories of the U.S. The wetland plant data are organized into ten regions that coincide with Corps wetland delineation regions.
