INTERRELATIONS OF WEATHER, FIRE, AND MOOSE ON THE KENAI NATIONAL MOOSE RANGE, ALASKA

Abstract

Moose populations on the Kenai National Moose Range in Alaska were monitored by spring, fall, and winter aerial surveys. Data indicate a positive response in moose productivity and density to disturbance by wildfire. Weather data indicated that summer precipitation and temperature influenced the type of habitat created by fire. Precipitation, temperature, and snow depth during the winter modified moose productivity and density. Severe winter weather slowed increases and accelerated declines while mild winter weather accelerated increases. Habitat quality appeared to determine whether the population was increasing or decreasing.
