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.

A Grand Slam for Students, Schools and Science

"It’s a grand slam for all involved,” said Dawn Childs, USGS Cooperative Fish and Wildlife Research Units.  “Recent high school graduates with special needs get real-world experience while helping USGS scientists on projects ranging from grizzly bears and energy to historic documents and bird migration. And a school system gets to successfully train students to enter the workforce."

The Cooperative Fish and Wildlife Research Unit (CRU) Program had a productive year in 2016. Despite vacancies in our scientist ranks exceeding 20 percent, our research, training, and teaching portfolio was full and we graduated 93 students and published 398 manuscripts primarily focused on addressing the real conservation challenges of our cooperators.

Metapopulation Dynamics of the Adélie Penguin

The Oregon Cooperative Unit, graduate students, and a group of U.S. and international collaborators are conducting long-term research on the Adélie penguin on Ross Island, Antarctica. This species depends on sea ice (obligate) and in some regions of Antarctica is being affected by climate change’s influence on sea ice patterns.

Unit scientists develop programs and applications to be used by State and Federal managers to conduct data analyses to inform decision making. The Colorado Unit co-authored the textbook “Bayesian Models: A Statistical Primer for Ecologists.” The Arizona Unit developed a simple, web-based tool to compare freshwater fish data collected using American Fisheries Society standard methods.
