The Cooperative Research Units Program conducts research on a wide range of disciplines related to fish, wildlife, and natural resource management. Our 40 Units collectively conduct research on virtually every type of North American ecological community. Most research projects are carried out by graduate students participating with and/or under the direction of unit or other university scientists. Collectively, the Units typically have more than 1,000 research projects under way and generate 250-300 scientific publications annually.

Unit research may be of local, regional, national, or international interest. The research programs conducted by units are approved as directed by the Coordinating Committee overseeing each unit.
