Cooperative Fish and Wildlife Research Units Program: Headquarters
Education, Research and Technical Assistance for Managing Our Natural Resources

Headquarters


Northern Pintail Drake at Colusa National Wildlife Refuge

The Cooperative Research Unit program was established in 1935 to enhance graduate education in fisheries and wildlife sciences and to facilitate research between natural resource agencies and universities on topics of mutual concern. Today, there are 40 Cooperative Research Units in 38 states. Each unit is a partnership among the U.S. Geological Survey, a State natural resource agency, a host university, and the Wildlife Management Institute.

Staffed by U.S. Geological Federal personnel, Cooperative Research Units conduct research on renewable natural resource questions, participate in the education of graduate students, provide technical assistance and consultation on natural resource issues, and provide continuing education for natural resource professionals.

We invite you to explore our website further and check out our research projects, meet our students, and review exciting, new research findings.
