of this wetland classification can be incorporated into 

 broader hierarchical land classifications. 



A classification system is most easily learned through 

 use. To illustrate the application of this system, we have 

 classified a representative group of wetlands and deep- 

 water habitats of the United States (Plates 1-86; pages 

 46-131). 



ACKNOWLEDGMENTS 



The breadth and complexity of preparing this classifica- 

 tion caused us to solicit help and advice from individuals 

 too numerous to list here. Frequently the recommenda- 

 tions were in conflict and we take responsibility for the 

 decisions we have made but acknowledge all suggestions 

 including those not accepted. Several meetings were 

 crucial in formulating the present classification and in 

 modifying earlier drafts. We thank those who attended 

 the formative meeting at Bay St. Louis, Mississippi, 

 January 1975; The National Wetland Classification and 

 Inventory Workshop at College Park, Maryland, July 

 1975; and the review panels assembled at Sapelo Island, 

 Georgia, and at St. Petersburg, Florida. We also thank 

 those individuals and agencies who responded to distribu- 

 tion of the operational draft. Special credit is due the 

 regional coordinators of the National Wetlands Inventory 

 and P. B. Reed, who have furnished continuing consulta- 

 tion on application of the system. Martel Laboratories 

 field-tested the system and furnished specific criticisms. 

 We were advised by J. Everett on geomorphology, K. K. 

 Young and 0. Carter on soil taxonomy, R. P. Novitzki on 

 hydrology, and R. H. Chabreck on coastal wetland ecology. 

 M. L. Heinselman and R. H. Hofstetter helped with dif- 

 ficult problems of peatland ecology and terminology. R. L. 

 Kologiski aided with botanical problems. J. H. Montanari, 

 W. 0. Wilen, and the entire National Wetlands Inventory 

 staff furnished encouragement and logistic support. The 

 staff of the Northern Prairie Wildlif e Research Center con- 

 tributed substantially to completion of the classification. 

 Art work and graphics were prepared by J. Rodiek, R. L. 

 Duval, and C. S. Shaiffer. J. H. Sather worked closely with 

 us and served as editor on previous drafts.
