ACKNOWLEDGEMENT S 



This report would not have been possible without the generous 

 financial aid and substantive guidance provided by three organiza- 

 tions: The Nature Conservancy, the Chesapeake Bay Foundation, and 

 the Irving Kingsford Charitable Trust. We are most indebted to them 

 for their kind support. 



We would also like to thank Smithsonian staff who are not part 

 of the Ecology Program but who nevertheless applied their valuable 

 time and services to this effort, especially the energetic volunteers 

 who came to us through the Smithsonian Associates volunteer program. 



We are grateful to all those in the scientific community and 

 other professions who have given their time and specialized compe- 

 tence to the study of natural history in the Bay region. We hope that 

 they are all credited properly in the pages that follow.
