The National List of Plant Soecies 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. 

 Araidei, 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. 



A special debt is owed to the regional ecologists who so generously gave of their 

 time and experience in reviewing the lists. Their review helped to refine the 

 information presented in the botanical manuals and in many cases provided the 

 only and often best description of the ecology of many plant species. The
