Data from standardized aerial surveys during 1964-90 were used to study the timing, extent and rate of decline of winter densities of moose (Alces alces) in early seral forest burned in 1969 (13-21 yr post-fire), in mid-successional forest burned in 1947 (17-43 yr post-fire) and in older successional forests (60-90+ yr post-fire) on the Kenai Peninsula. Results are discussed in relation to habitat management required to maintain moose populations.
