Wetland Plants and Plant Communities of Minnesota and Wisconsin

Acknowledgements


This pictorial guide to wetland plants is not an original idea. Other U.S. Army Corps of Engineers districts/divisions have produced similar guides for different parts of the nation. Pictorial guides covering other groups of plants have also been used as models for this guide, such as Wildflowers of the Northern Great Plains by Vance et al. (1984). Furthermore, we have borrowed extensively from the authoritative botanical references by Gleason and Cronquist (1991), Swink and Wilhelm (1994), Voss (1972, 1985), and others. We acknowledge this fact by citing these references throughout the guide.

We are indebted to Charles J. Newling (formerly with the U.S. Army Corps of Engineers, Waterways Experiment Station - Vicksburg) and Dr. James H. Zimmerman who were instrumental in formulating the guide. We are also grateful to Dr. Daniel E. Wujek (Central Michigan University), Welby R. Smith (Minnesota Natural Heritage Program) and John M. Kittelson (formerly with the St. Paul District - Corps) for their review and comments on the draft manuscript. Other individuals on the staffs of the St. Paul District - Corps and Southeastern Wisconsin Regional Planning Commission who assisted in preparation of the guide are too numerous to list, but are gratefully acknowledged.

Many thanks to Dr. Gerald B. Ownbey (Professor Emeritus - University of Minnesota) for his assistance on nomenclature, and Dr. Jan A. Janssens (University of Minnesota) for his assistance in identifying Sphagnum. Grady E. Mann (formerly with the U.S. Fish and Wildlife Service) provided valuable assistance on the map of the Prairie Pothole Region.

In addition, we wish to thank the following artists for contributing their fine ink drawings: Vera M. Wong did the taxonomic character drawings and some of the glossary drawings; Elsie Froeschner did some of the drawings of grasses; other drawings of grasses are from Hitchcock (1950); Patricia A. Trochlell (Wisconsin Department of Natural Resources) did additional drawings for the glossary; and Anne L. Martin (formerly with the St. Paul District - Corps) did the plant community schematics. The drawings by Vera M. Wong are copyrighted and may not be reproduced without her permission.

Finally, we express our appreciation to the University of Minnesota; specifically, the staff of the Cedar Creek Natural History Area, for their cooperation and assistance.
