Biotechnicians collect information about a nest at Yukon Delta Refuge.

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.
