Published by U.S. Fish and Wildlife Service | Department of the Interior | Metadata Last Checked: January 07, 2026 | Last Modified: 2006-01-01T00:00:00Z
We conducted moose surveys in the western Yukon Flats in March and November 2006. The surveys were initiated to estimate early winter moose abundance in the traditional2,269 mi2 moose survey area and to estimate early and late winter moose densities in lands proposed for exchange between the Yukon Flats National Wildlife Refuge (Refuge) and Doyon, Limited (Doyon). The March 2006 population estimate for exchange lands in the western Yukon Flats (578 rni2 survey area) was 65 moose+/- 33% at the 0.90 confidence level; the mean density estimate was 0.11 moose per mi2 +/-33%, 0.90 confidence level. The November 2006 population estimate for exchange lands surveyed in the eastern and western Yukon Flats (1,108 mi survey area) was 249 moose +1- 31% at the 0.90 confidence level; the mean density estimate was 0.22 moose per rni2 +/- 31%, 0.90 confidence level. Of the land parcels proposed to be received by the Service in the proposed land exchange, approximately 63% include average to high moose densities in early winter and all parcels have low densities of moose in late winter. Parcels proposed to be received by Doyon are characterized by low moose densities in both early and late winter.
