美洲獾
Eighty-two mammal species are predicted to be found in the Noyo River watershed including several rodents, bats, and squirrels, beaver ("Castor canadensis"), black bear ("Ursus americanus"), ring-tailed cat ("Bassariscus astutus"), American marten ("Martes americana"), fisher ("Martes pennanti"), weasels, American badger ("Taxidea taxus"), western spotted skunk ("Spilogale gracilis") and striped skunk ("Mephitis mephitis"), mountain lion ("Puma concolor"), bobcat ("Lynx rufus"), seals and sea lions, mule deer ("Odocoileus hemionus"), and elk ("Cervus elaphus"). However, recent surveys have found no fishers or martens.
