Question
Moose and Winter Ticks Significant mortality of moose (Alces alces) occurred throughout broad regions of northern and western Alberta in early 1999. Occurrences* involving moose were recorded at local Alberta Natural Resources Service (NRS) district offices. A total of 1130 occurrence reports involving moose throughout Alberta between January 1 and April 30, 1999 were submitted to the author for review. Although there was considerable inherent bias in the sample, some general patterns emerged. Most moose (92 percent) had evidence of hairloss and 28 percent of them were dead. In the overall sample, 35 percent were calves; however in the subsample of dead moose with hairloss, 43 percent were calves. It is assumed that the hairloss was a result of infestation with winter tick, Dermacentor albipictus. Most occurrences (96 percent) were within the boreal habitats of northern and western Alberta and half of them were recorded in March (50 percent). It is apparent that excessive mortality of moose, particularly calves, occurred in late winter. The outbreak is considered a direct result of the interactions among moose, ticks, habitat, and weather. Weather appears to have been the ultimate force driving the interactions. Late winter snow cover, and moose densities may provide clues for potential management actions in the subsequent fall period. Occurrences include situations in which officers or biologists directly handle an animal, receive phone calls from the public or industry regarding animals in distress or found dead, and situations in which wildlife become a nuisance or a concern for public safety.
