The park aims to protect black bear, mule deer, moose, mountain goat, cougar, and beaver. Ecologically sensitive animal populations found in the area include California bighorn sheep, grizzly bear, fisher, wolverine, bald eagle, and amphibian species. Sockeye salmon spawn along the shores of Chilko Lake the centerpiece of the park. The adjacent lands are also important habitat for Vaux's swift, Peregrine falcon, and Townsend's big-eared bat.
