MANAGEMENT OF MOOSE POPULATIONS: WHICH PARAMETERS ARE USED?
This paper discusses the collection and application of moose aerial survey data by management jurisdictions in North America. Of 17 jurisdictions sampled, 16 flew surveys and of these 15 did population surveys and classified counts while one did classified counts only. The frequency of aerial surveys varied from 1 to 10 years with most flying at 2 to 5 year intervals. Information relative to how the data are used and criteria for assessing population health are presented. Eleven agencies collected age data and the use of it is presented. Ten agencies indicated that they use a population model for simulating populations. Twelve parameters for assessing the health of moose populations are presented and recommended for use. In the interest of maintaining long term monitoring programs, parameters used should be simple, stable and cost effective. These are more likely to be used by managers. Monitoring programs should be directed at those parameters which will be leading indicators of future trends in moose populations.
