ACKNOWLEDGMENTS 



The National List of Plant Species That Occur in Wetlands 

 (hereafter referred to as the National List ) is the result of the 

 collective efforts of a large number of dedicated biologists. 

 Special recognition and thanks are extended to the many people who 

 contributed to the successful completion of this project. The 

 National Wetlands Inventory, especially John Montanari and William 

 Wilen, provided the funding and administrative support necessary 

 for the development of the National List and coordination of the 

 review effort. 



The other Federal agencies, especially William Sipple, John 

 Meagher, and Dave Davis of the Environmental Protection Agency, 

 Robert Pierce, Richard Macomber, and Dana Sanders of the Corps of 

 Engineers, and Billy Teels and Carl Thomas of the Soil Conservation 

 Service, provided much needed funding to aid development of the 

 Annotated National Wetland Plant Species Data Base and technical 

 support through their agency biologists' participation in the 

 review effort. 



Special recognition and appreciation is extended to Lewis Cowardin 

 who conceived the need for the National List , supervised the 

 compilation of the initial draft list, and provided invaluable 

 advice and direction during the initial phase of the project. 



The contribution of the authors of the almost 300 regional and 

 State floras and regional wetland manuals used in compiling the 

 Annotated National Wetland Plant Species Data Base is gratefully 

 acknowledged . 



The development of the National List was greatly facilitated by the 

 dedicated staff who contributed over 50 person years to compile the 

 Annotated National Wetland Plant Species Data Base. This data base 

 provided a solid information base from which the National List was 

 derived. This staff included Karen E. Amidei, James G. Armstrong, 

 Sheryl A. Brenner, Steven I. Candileri, Mark A. Charneski, Diana 

 Fry, Thomas B. Gunter, Lillian A. Gustafson, Iris A. Kendall, Mary 

 E. Klee, Annie L. Kosvanec, David R. Lindsey, Stephen Mortellaro, 

 Kent A. Moyer, Laura E. Pittman, Donald R. Richardson, Richard N. 

 Rowse, Angela F. Salem, Deana Ulmer, Sheri A. Ulrich, Sandra M. 

 Upchurch, Diane Wallace, Debora L. Wegner, August M. Wooten and 

 Kevin R. Youngberg. This landmark effort to collect much of the 

 taxonomic and ecological information about wetland plants into a 

 textual computer data base was a protracted and extremely tedious 

 task. It was truly a pleasure to work with such a productive and 

 conscientious group.
