National Wetland Plant List

The U.S. Army Corps of Engineers (Corps), as part of an interagency effort with the U.S. Environmental Protection Agency (EPA), the U.S. Fish and Wildlife Service (FWS) and the U.S. Department of Agriculture Natural Resources Conservation Service (NRCS), is announcing the availability of the final 2016 National Wetland Plant List (NWPL). The NWPL is used to determine whether the hydrophytic vegetation parameter is met when conducting wetland determinations under the Clean Water Act and the Wetland Conservation Provisions of the Food Security Act. Other applications of the list include wetland restoration, establishment, and enhancement projects. The list will become effective on May 1, 2016 and will be used in any wetland delineation performed after this date. Delineations received prior to this date may still use the 2014 NWPL, or you may choose to use the 2016 list. Always reference the list used on any wetland delineation/ determination forms.
