Abstract:
Population dynamics of moose (Alces alces) were investigated in Algonquin
Provincial Park based on long-term studies of moose population abundance
and factors influencing demographics, 1976-94. In addition, intensive
monitoring was conducted from 1990-93 on 76 radio-tagged animals (27 adults
and 1 yearling female, 47 neonates) and 16 untagged neonates to determine
reproductive performance, survival rates, and cause-specific mortality agents.
Aerial survey methods indicate that the detection of ±10% change in
population abundance is possible. Reproductive performance from 1990-93
shows average production of 0.95 calves/cow and twinning rate of 18% which
suggests Algonquin Park’s population may be near or at ecological carrying
capacity. Estimated yearling productivity was within the range reported
in the literature for moose populations across North America. Annual
survival rate for adults (0.94) and estimated yearling survival (0.88) correspond
to rates observed in other populations across North America. However,
annual calf survival (0.61) is high compared to other populations where both
black bear (Ursus americanus) and wolves (Canis lupus) are
sympatric. Winter weather had not played a significant role in moose
population dynamics in the past 18 years. Winter tick (Dermacentor
albipictus) causes mortality in both young and adults, but does not appear
to have a significant influence on overall population change in either the
current year or subsequent years. Long-term population trends and growth
rates appear to be mediated primarily by ecological carrying capacity.
Increasing visitor use of Algonquin Park and changes in policy allowing Native
harvest may place additional stress on the population, thus warranting continued
monitoring.
