Characteristics of wolverine reproductive den sites

Article Abstract:

Wolverine reproductive dens in Idaho and Alaska were characterized and compared. Dens in Alaska were usually long, complex snow tunnels with no trees or boulders, while dens in Idaho were associated with fallen trees or boulders. Most of the dens had been located in alpine, subalpine, taiga or tundra habitat. Thermoregulatory advantages, protection from predators, suitability of the site during spring and location of rearing habitat were factors which may have influenced den site selection.
