Programs L2 Landing Page

Established in 1935, our mission is our hallmark: meet the actionable science needs of our cooperators, provide technical assistance, and develop the future workforce through graduate education/mentoring. The Coop Units are located on 40 universities in 38 states. They are called Coop Units because each cooperator plays a role in the staffing, funding and directing the units.

New Maps Document Big-Game Migrations Across the Western United States

LARAMIE, Wyo. – For the first time, state and federal wildlife biologists have come together to map the migrations of ungulates – hooved mammals such as mule deer, elk, pronghorn, moose and bison – across America’s West. The maps will help land managers and conservationists pinpoint actions necessary to keep migration routes open and functional to sustain healthy big-game populations.

The CRU program remains very productive and maintains a bright future. One of the things contributing to that bright future is a $5.6 million increase in our most recent Congressional appropriations. This amount will help us meet longstanding programmatic needs, such as filling all the vacancies in our scientific workforce and providing much-needed upgrades to our research equipment.
