Abstract
Presented is a subset of the National List of Plant Species That Occur In Wetlands of the north central region of the United States. This area includes Missouri, Iowa, Minnesota, Wisconsin, Illinois, Indiana, and Michigan. The list was initiated by the US Fish and Wildlife Service, National Wetland Inventory (NWI). A candidate national list of more than 5000 species was developed and using information from more than 250 taxonomic references, the NWI assigned a tentative wetland indicator status to many of the species. The indicator status categories define the estimated probability of a species occurring in wetlands. For purposes of this manual, any plant species not appearing on the plant list was assumed to be an upland species unless a strong technical rationale could be developed for adding it to the list.
