The U.S. Department of Agriculture's National Wildlife Research Center (NWRC) is the federal institution devoted to resolving problems caused by the interaction of wild animals and society. The Center applies scientific expertise to the development of practical methods to resolve these problems and to maintain the quality of the environments shared with wildlife.

This site contains publications of the NWRC or its staff. Material prepared by employees of the US Government in the course of their official duties cannot be copyrighted.
