10 June 2019  - 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, announces the draft biennial update to the National Wetland Plant List (NWPL) for 2018 in the Federal Register.  The Corps encourages public input in the form of data, comments, literature references, or field experiences, to help clarify the status of the species reviewed for this update, as well as public input on the NWPL process.  The public will have the opportunity to comment on the proposed update or addition of wetland indicator status ratings for 20 plant species in select Corps wetland regions.  These 20 reviewed species and their draft 2018 wetland ratings by region, as well as the FR notice, can be viewed at the NWPL homepage, under “2018 NWPL Update Information.” A link to provide general or species-specific comments is also available at this location. Users are encouraged to submit literature citations, herbaria records, experiential references, monitoring data, and other relevant information. Specific knowledge of, or studies related to, individual species are particularly helpful. Commenters should use their regional botanical and ecological expertise, field observations, reviews of the most recent indicator status information, appropriate botanical literature, floras, herbarium specimens with notation of habitat and associated species, habit data, relevant studies, and historic list information. Guessing ratings is inappropriate. All submitted comments and information will be compiled and sent to the National Panel for their consideration.

The Corps is also seeking comments on the NWPL update process. Detailed information on the update process, protocol, and technical issues can be found in the following documents (available on the NWPL Publications web page referenced above):

San Francisco District Regulatory Division


As chief federal steward of wetlands - marshes, tidelands and vernal pools - the Corps' regulatory team has responsibility for regulating and enforcing rigorous environmental standards while balancing appropriate development. The Corps’ efforts to balance society’s many needs officially begin with the permit process. In cases where an impact on aquatic resources is unavoidable, organizations must obtain a permit from the Corps.  This process is designed to be fair and flexible and to provide timely decisions. In many cases, the Corps works with potential applicants during the planning and design of projects so that problems can be spotted early on and addressed, saving development costs while still reducing potential environmental harm.  The Corps is committed to ensuring that the public has the opportunity to provide input on projects that will have more than a minimal impact on the environment. In carrying out its regulatory program, the Corps works closely with a diverse array of federal, state, tribal and local government agencies, nonprofit groups, businesses and individuals.
