Cooperative Research Units
Established in 1935 at Iowa State University, our mission is our hallmark: work with University students to develop the conservation workforce, help decision-makers make complex conservation decisions, and to provide technical assistance between natural resource agencies and universities. We support 43 units located in 41 States, at 44 host universities. Our Program Office is in Reston, VA.

Bird community response to field-level integration of prairie strips
Grassland birds are under threat worldwide due to loss of habitat to agriculture. Prairie strips are a new agricultural conservation practice composed of linear strips of reconstructed diverse, native, herbaceous, perennial vegetation designed to promote land sharing among agriculture and biodiversity, while also addressing soil and water conservation goals. We evaluated bird community response to
Biogeochemical and community ecology responses to the wetting of non-perennial streams
Transitions between dry and wet hydrologic states are the defining characteristic of non-perennial rivers and streams, which constitute the majority of the global river network. Although past work has focused on stream drying characteristics, there has been less focus on how hydrology, ecology and biogeochemistry respond and interact during stream wetting. Wetting mechanisms are highly variable an
Predicting future grizzly bear habitat use in the Bitterroot Ecosystem under recolonization and reintroduction scenarios
Many conservation actions must be implemented with limited data. This is especially true when planning recovery efforts for extirpated populations, such as grizzly bears (Ursus arctos) within the Bitterroot Ecosystem (BE), where strategies for reestablishing a resident population are being evaluated. Here, we applied individual-based movement models developed for a nearby grizzly bear population t

Sustaining Horseshoe Crabs and Supporting Migratory Shorebirds in the Delaware Bay
USGS is developing predictive models to inform sustainable harvest of horseshoe crabs ( Limulus polyphemus) in Delaware Bay to help managers make decisions to support needs of people and shorebirds including rufa red knot ( Calidris canutus rufa ).

USGS Alaska Science Center Wildlife Tracking Data Collection
Understanding the short- and long-distance movements of wildlife is critical for a wide variety of ecological research questions and management decisions. Since the mid-1980s, the USGS Alaska Science Center has used information from telemetry devices on wildlife species to determine locations of animals throughout their annual cycles, understand patterns of habitat use, quantify time spent on...
