National Wetland Plant List (NWPL) : *NEW* May 21, 2020 NWPL 2018 Update -
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 2018 National Wetland Plant List (NWPL). The Federal Register Notice for the 2018 NWPL update can be found here: https://www.govinfo.gov/content/pkg/FR-2020-05-18/pdf/2020-10630.pdf.
The NWPL provides plant species 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 May 18, 2020 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 http://wetland-plants.usace.army.mil/. State, regional, and national lists can also be downloaded from this site.
1987 Wetland Delineation Manual - An electronic version of the 1987 Corps of Engineers Wetland Delineation Manual (1987), which along with the supplements (the ones used in Buffalo District are below) is the current Federal delineation manual used in the Clean Water Act Section 404 regulatory program for the identification and delineation of wetlands. Except where noted in the manual, the approach requires positive evidence of hydrophytic vegetation, hydric soils, and wetland hydrology for a determination that an area is a wetland.
