Woodland caribou conservation in the Little Smoky: wolf management and the role of bears

  • Woodland caribou population declines in west-central Alberta precipitated a wolfcontrol. This program to protect caribou could be compromised if (1) there are strong public pressures against helicopter gunning and strychnine poisoning of wolves and/or (2) other predators compensate to kill caribou. Because bears can be important ungulate predators, I used stable isotope techniques to reconstruct black and grizzly bear diets including contributions of caribou, caribou calves, ants, ungulates (moose, deer and elk), and 3 plant groups. Bears assimilated 2-58% terrestrial protein indicating large variation among individuals. As an alternative to current wolf-control practices, I reviewed spatial and temporal patterns of harvests (1985-2006) on registered traplines. Wolf trapping has increased during the past 2 decades, but on average trappers harvested only 10% of the provincial wolf population, well below culls required to control the population. Under the registered trapline system it is unlikely that trapping could control wolf abundance.
