Owen PA and Meier TJ. 2009. 2008 Aerial Moose Survey Denali National Park and Preserve. Denali Park, Alaska
We estimated the number of moose (Alces alces) on the north side of the Alaska Range mountains in Denali National Park and Preserve. The 10,004 km2 (3862 mi2) area was surveyed from 3 through 25 November 2008. We observed 830 moose during the aerial survey and estimated (+90% confidence interval [CI]) 1279 +135 moose for the entire survey area. Overall density was 0.13 moose/km2(.33 moose/ mi2). The calf:bull:cow ratio was 24:54:100. We estimated that 77% of cows were without calves, 22% of cows had 1 calf, and 1% of cows had 2 calves present. Two smaller portions of the survey area (East End and Kantishna) were also analyzed.
