The following links provide useful information to help identify plants in the field, including wetland vegetation.
Plant Identification Guides
Plant identification guides can aid biologists with proper identification of plant species in the field, such as when determining whether an area meets the criteria for classification as a wetland, or in assessing the floristic quality of a site for natural areas protection.
SEWRPC has also prepared lists of plants suitable for landscaping in Southeastern Wisconsin. Click here for Landscaping Guides and Invasive Species Eradication information.

Additional plant identification aids:
University of Michigan Flora Online -- specific to Michigan, but well-built keys that are helpful for identifying most species that occur in Southeast Wisconsin, often with photographs and descriptions of habitat.
Robert W. Freckmann Herbarium -- Maps of Wisconsin plant collections, often with images and brief descriptions
University of Wisconsin-Green Bay Herbarium -- Keys for trees, shrubs, and ferns etc. native to Wisconsin
Plant Species Range Maps
Since the introduction of the Natural Areas Plan in 1991, SEWRPC has been systematically cataloging known locations of all vascular plant species (i.e., ferns, conifers, and flowering plants) that occur within the seven-county Region. As a result of these efforts, up-to-date, detailed range maps have been prepared for all of these 1,813 species. more
For several years, the wetland shrub key below (or earlier versions thereof) has been part of wetland plant identification training courses involving SEWRPC, where there was a need to provide a concise, workable aid to facilitate identifying shrubs typically found in wetlands. It is intended to be used in the field, with the only tools being a hand lens and a metric ruler. It also should be pointed out that this key is designed for use in the State of Wisconsin; it will not necessarily work elsewhere, even in neighboring states.
