The Pacific fisher, a relative to the mink and otter, is a medium-sized forest mammal that lives in mature and old growth forests.

It disappeared from more than half its former range in California and is in danger of becoming extinct in the state.

This project, funded by Conservancy donors, collected data necessary to determine the abundance, distribution, and possible population limiting factors that have led to the continuing scarcity of Pacific fishers.

Now that scientists have a better understanding of the causes behind Pacific fisher scarcity in the park, proactive steps are being taken to help restore the animal to the park.
