This Pennsylvania Comprehensive Wildlife Conservation Strategy (CWCS) was for partial completion of requirements for continued funding of the State Wildlife Grants Program in Pennsylvania. The CWCS (Williams, L., et al. (eds.). Pennsylvania Comprehensive Wildlife Conservation Strategy. Pennsylvania Game Commission and Pennsylvania Fish and Boat Commission. Version 1.0 (October 1, 2005). 772 pp + appendices.) provided a solid and detailed basis for wildlife conservation by both commissions. The following materials does not include data appendices in original report that included findings from extensive fieldwork conducted in 2004-2005 with funding from a State Wildlife Grant entitled “Pennsylvania Invertebrates of Special Concern: Viability, Status, and Recommendations for a Statewide Comprehensive Wildlife Conservation Plan in Pennsylvania.” That project was collaborative between staff in the Section of Invertebrate Zoology at Carnegie Museum of Natural History, and personnel from the Western Pennsylvania Conservancy under the supervision of Charles. W. Bier, and staff of the Pennsylvania Science Office of The Nature Conservancy under the supervision of Anthony Davis (later Greg Czarnecki). The primary difference between this document and the original Appendix 5 submitted in 2005 is the inclusion of findings from fieldwork, especially inclusion of additional species in various conservation categories. Acknowledgments Special appreciation is extended to collaborators and administrators who made this project possible, including Charles W. Bier and Ryan E. Miller (Western PA Conservancy), and Nancy Clupper, Anthony Davis, Greg Czarnecki, and Betsy J. Ray (The Nature Conservancy). For tolerance, guidance, and abundant patience I thank Patricia Barber and Lisa Williams (PA Game Commission). Designer Rita M. Lee provided tremendous help with designing and formatting this report. The Carnegie Museum staff in the Section of Invertebrate Zoology undertook sorting, preparation and authoritative identification, led by coordinator David P. Koenig, and involving amazing input from Robert A. Androw, Robert L. Davidson, Deborah Denovich, Hillary Fetzner, Dr. James W. Fetzner, Jr., Jane C. Hyland, Timothy J. Tomon, Vanessa Verdecia, Dr. Chen W. Young, and Walter A. Zanol. Field work oversight at The Nature Conservancy was provided by Betsy J. Ray (Leppo), and by Ryan E. Miller and Tam Smith for the Western PA Conservancy. Data on special concern listings was supplemented by Kierstin Carlson of the Western PA Conservancy. The project benefited enormously from the field collecting efforts of many persons, including most of the above mentioned persons and Trudy Beal, Daniel Bogar, Donna E. Bowers, M.

In practice, this means stabilizing or improving the conservation status of individual species, keeping the status of most native species from worsening, and, in a few cases, preventing the extirpation of endangered species from Pennsylvania habitats. The practical outcome of an effective conservation strategy will be to prevent additional species from
