Wetland Plants

National List of Plant Species that Occur in Wetlands:

• 1988 Official Wetland Plant List & 1993 Supplement National List of Plant Species That Occur in Wetlands: 1988 National Summary. Porter B. Reed; for U.S. Fish and Wildlife Service in cooperation with the U.S. Army Corps of Engineers, U.S. Environmental Protection Agency, U.S. Soil Conservation Service. This list is referenced in the Federal Manual for Identifying and Delineating Jurisdictional Wetlands, and in the Natural Resources Conservation Service’s procedures to identify wetlands for the Swampbuster provision of the Farm Bill.

• 1996 draft revision. The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary. The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments.

The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1998 National List. This revision is currently undergoing administrative review by the Fish and Wildlife Service. When it is approved for official release, the Service will make it available here in both readable document form and export files suitable for downloading.

Software:
• Wetland plant identification, electronic random access identification key to wetland plants. MEKA/MARSH - Multiple Attribute Recognition System for Hydrophytes - Zip file for downloading.
• Spell checking for scientific plant names and acceptance status. Sounds Like interactive online version or Zip file for downloading.

Introduction
Wetlands support a high diversity of plants far in excess of what would be predicted when considering the relative land area they occupy. Although wetlands comprise 5 percent of the land area of the continental United States, over 30 percent of the nation's vascular flora occur in wetlands.

The Service develops, maintains, and distributes data and information on wetland plants and plant communities. The list of wetland plants and the software for a wetland plant identification system aid in the identification and understanding of wetland systems.
