This park has a diversity of animal species including 75 mammal species. A total of 18 species of carnivores including coyote, bobcat, lynx, cougar, mink, river otter and black bear have been reported within this park. Several species of deer such as the elk and moose, several more species of bovids including the mountain goat and bighorn sheep, and more than two dozen species of rodents like the beaver, hoary marmot and pika are also present. Ten species of bats have been documented. The grey wolf is listed as an endangered species, while the grizzly bear is listed as threatened. North Cascade National Park has management plans in place to return grizzly bears to the park but not wolves, as the latter is seen as likely to reestablish themselves naturally over time.
