Alaska's Yukon Delta National Wildlife Refuge is vast and productive. The refuge nestles between Alaska’s largest rivers, the Yukon and the Kuskokwim Rivers, where the tundra meets the Bering Sea. Its diversity of habitats support one of the largest aggregations of waterbirds in the world. The hundreds of miles of rivers and streams provide critical spawning and rearing habitat for Pacific salmon species. Drier upland habitats harbor populations of brown and black bears, caribou, moose, wolves, and muskox. Along the coast, the Bering Sea waters host various marine mammals, including whales that pass during migration.

This landscape is the ancestral home of the Yup’ik, Cup’ik, and Deg Xit'an people of Alaska. This is a region rich in culture, where residents depend on resources to support an active subsistence way of life. The Yukon-Kuskokwim Delta is among the most populated rural areas in Alaska, with over 50 Indigenous communities.

      The Yukon Delta Refuge works with partners and communities to conserve fish and wildlife populations and their habitats. Biologists conduct monitoring and research efforts on species of natural and cultural significance, and where adequate, provide the science to support sustainable subsistence opportunities in the Yukon-Kuskokwim region.

      Current monitoring and research efforts include:

      • Kuskokwim fisheries harvest surveys, with emphasis on Chinook salmon
      • Monitoring and management efforts of emperor geese
      • Monitoring of Threatened and Endangered species, such as Steller’s eiders
      • Monitoring and management of Mulchatna caribou.
