About the Pennsylvania Unit

Electrofishing brown and rainbow trout in Spruce Creek in central Pennsylvania

Cooperative Research Units have three facets to their mission: Education, Research, and Technical Assistance.

The mission of the Pennsylvania Cooperative Fish and Wildlife Research Unit is to conduct interdisciplinary applied and basic research in fish and wildlife management and contribute to graduate education.

The Unit's research emphasis is on integrating ecology and management of terrestrial and aquatic habitats, evaluating the effects of human activities on wildlife, fish, and their habitats, and providing guidelines for restoring and maintaining important terrestrial and aquatic communities.

Unit personnel contribute to graduate education by engaging graduate students in research projects and teaching graduate level courses.

Duane R. Diefenbach

Upon completion of my Ph.D. I worked for the Pennsylvania Game Commission as their biometrician for 7 years. There I began my current research involving grassland sparrows and black bears. Since 1999 I have been a research scientist with the Pennsylvania Unit and enjoy the challenges in integrating research to improve management decisions.
