Successful moose management depends on knowledge of population dynamics. The principal population parameters required are size, rate of change, recruitment, sex composition, and mortality. Moose management in Alaska has been severely hampered by the lack of good estimates of these parameters, and unfortunately, this lack contributed to the decline of many Alaskan moose populations during the 1970s. The problems were: 1) population size was not adequately estimated, 2) rapid rates of decline were not acknowleged until populations were low, 3) meaningful recruitment rates were not available in the absence of good population estimates, and 4) calf and adult mortality rates were grossly underestimated.
