2 November 2021 - The U.S. Army Corps of Engineers, as part of an interagency effort with the U.S. Environmental Protection Agency, the U.S. Fish and Wildlife Service, and the U.S. Department of Agriculture Natural Resources Conservation Service, is announcing the availability of the final 2020 National Wetland Plant List (NWPL). The Federal Register Notice for the 2020 NWPL update can be found here: https://www.federalregister.gov/documents/2021/11/02/2021-23891/national-wetland-plant-list.
The NWPL provides plant species wetland indicator status ratings, which are used in determining whether the hydrophytic vegetation factor is met when conducting wetland delineations under the Clean Water Act and wetland determinations under the Wetland Conservation Provisions of the Food Security Act. Other applications of the NWPL include wetland restoration, establishment, and enhancement projects. The list is effective as of 2 November 2021 and will be used in any wetland delineations performed after this date. Completed wetland delineation/determination forms should reference the version of the NWPL used to complete the form. The final NWPL is available at https://wetland-plants.sec.usace.army.mil/ (preferred browsers are Chrome and Firefox).
Questions regarding the NWPL and the 2020 updates should be directed to Paul Minkin, NWPL Director, and Bri McGuffie, HQ USACE Regulatory Program Manager.
