Description: Martens and fishers, as predators, perform important functions that help sustain the integrity of ecosystems. Both species occur primarily in mature forest environments that are characterized by dense canopy, large-diameter trees, a diverse understory community, and abundant standing and downed dead trees. Martens occur in the upper montane forests, where the threat of wildfire is less, and fishers predominately occur in the lower montane forests, where the threat of severe wildfire is much greater. Both species use habitat at multiple scales: the resting/denning site, the stand, the home range, and the landscape. Thus, management of habitat may benefit from considering these components when evaluating the effects of treatment activities. These species’ diets are relatively diverse and their prey occurs in a variety of habitats within their home ranges. It appears that the heterogeneous conditions that are predicted to occur with the restoration of fire as a disturbance process may yield habitat for martens, fishers, and their diverse sources of food.
