A cross section of mammals associated with the life zones of the region is found on the Refuge. Some indigenous species have disappeared; bighorn sheep are only memories while fisher have not been seen for a generation. For specific information on the status and distribution of mammals on the Refuge, contact the Refuge office.

variation, scientific names have been included. Names follow Dr. Phillip Wright, Professor
