Wolf-Caribou Interactions in the Fortymile Caribou Herd

January 2021 - April 2024


Participating Agencies

  • Alaska Department of Fish and Game Division of Wildlife Conservation

We are evaluating the interactions of wolves and migratory caribou in the Fortymile herd. Using detailed information from GPS collared wolves and caribou, we are evaluating the relative influence of habitat conditions on seasonal movements and predator-prey dynamics. Additionally, we are evaluating the extent to which caribou movements affect wolf distribution on the landscape during aerial surveys in order to assess the potential for bias in population estimates.
