    • Data for moose population survey of the western Yukon Flats – Spring, March 2023

    Metadata Updated: March 15, 2025

    A moose population survey was conducted on the Yukon Flats National Wildlife Refuge in March 2023. Moose were counted in 102 of 421-5.3 mi2 units, of which 67 were stratified high moose density and 35 low density. The estimate for the 2,269 mi2 survey area in the western Yukon Flats (Alaska Game Management Unit [GMU] 25D) was 675 total observable moose (95% CI; 509-841). Density of moose was 0.30/mi2 or 0.11/km2. The population was comprised of an estimated 589 adults (95% CI; 441-736) and 88 calves (49-128). Search time averaged 5.8 minutes/mi2. Spring moose numbers were above the long-term average (average 554, range 300735). The proportion of calves was intermediate relative to past spring surveys. Moose on the western Yukon Flats continue to persist at low densities, which has been documented for >60 years.
