This is a nation-wide collaborative program, supported by the USGS Ecosystems Mission Area, through which USGS and U.S. Fish and Wildlife Service staff address priority research needs identified by the U.S. Fish and Wildlife Service. On this page, we highlight research taking place in Alaska as part of this program.
Return to Ecosystems >> Collaborative Science for Priority Information Needs
U.S. Fish and Wildlife Service priorities change annually through this program. Results of past studies can be found under Data and Tools and Publications on this page.
For 2020-2023, the USGS Alaska Science Center is focusing on the following science needs identified by the U.S. Fish and Wildlife Service Alaska Region:
- Processing and publication of high-resolution coastal walrus haulout survey imagery
- Quantifying groundwater and aufeis and their contribution to surface water availability and habitat in the Arctic National Wildlife Refuge, Alaska
- Distribution and abundance of breeding waterbirds in relation to habitat type on the 1002 Area of the Arctic National Wildlife Refuge, Alaska
- Development of a population monitoring plan for the Southern Beaufort Sea polar bear subpopulation
- Assessing the population status of two rare taxa endemic to the central Bering Sea, Alaska: McKay's Bunting and Pribilof Rock Sandpiper
- Improved mapping of historical fire perimeters on Alaska National Wildlife Refuges
