Distribution Overlap between Fishers and American Marten Poster - 2012 West Coast Fisher Symposium


Fishers are much larger than American marten and compete with marten for the same prey types (squirrels and other small rodents). As part of resource competition between the two species, fishers will attack and attempt to kill marten when they come across them. For this reason marten avoid fishers by occupying higher elevation habitats where winter snow conditions are difficult for the larger, heavier fishers to negotiate. This poster uses survey camera detections for fishers and marten to evaluate how much distribution overlap there is between the two species in the Sierra National Forest, and those data are interpreted in relation to competitive interactions and coexistence.

This poster is presented by the Fisher team at the 2012 West Coast Fisher Symposium.
