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 National 

 List would not be as accurate and complete if it were not for the 

 enormous amount of review so generously provided by the regional 

 reviewers . State distributions and common names provided by John 

 Kartesz from unpublished data bases allowed the production of 

 accurate State lists and common name assignments for almost all 

 species. The high quality and completeness of the National List 

 is in large part due to the data provided by John Kartesz from the 

 Biota of North America Program. 



The composition and pleasing format of the lists is largely due to 

 the computer skills of Greg Auble of the National Ecology Research 

 Center and to the untiring and conscientious efforts of Iris 

 Kendall of the National Wetlands Inventory. 



The contributions of the many National and regional review panel 

 members is gratefully acknowledged. These biologists represented 

 their agencies in a technically competent and thoroughly 

 professional manner. The strength of the Regional lists and 

 Indicator assignments is largely due to the diverse background of 

 the review panel members and a firm desire by all to make the 

 process work. The unswerving resolve and determination displayed 

 by all the review panels to complete each phase of the task during 

 the marathon regional review panel meetings was truly inspiring. 

 Well over 200 weeks of staff time was contributed by the review 

 panel members . 



It has been a pleasure to coordinate this effort and to work so 

 closely with so many dedicated and professional biologists. The 

 credit and recognition for the completion of this task applies 

 equally to all who contributed so much. As compiler, I must 

 necessarily take the responsibility for any transcription errors 

 which may have occurred during the production of this report. The 

 extensive use of the National List has made the entire effort 

 professionally satisfying for all who have contributed.
