PREFACE 



The purpose of this series of species accounts is to provide resource managers and the 

 public with information about Federally listed endangered and/or threatened vertebrate 

 species that occur along, or within 100 kilometers of, the seacoast of the United States. In- 

 formation about life history, distribution, requirements and conservation of the subject 

 species is included (range maps and other distributional data arc not necessarily equivalent 

 to critical habitat as defined in the Endangered Species Act of 1973, as amended). 



This series of accounts is intended to complement the computerized Sensiti\c Wildlife 

 Information System (SWIS) developed by the U.S. Army Corps of Engineers in coordina- 

 tion with the Offices of Endangered Species and Biological Services of the Fish and Wildlife 

 Service. A 3-ring binder is used for this series to facilitate additions and deletions as new 

 accounts are prepared or as the status of species is changed.
