This ecoregion provides important habitat for large mammals such as mountain goats, elk, and black bear. Wide-ranging and rarely seen carnivores, including lynx, gray wolves, grizzly bears, and wolverines, can find a home here because it has experienced less residential development and logging disturbance than other regions of the Cascade Mountains.

The North Cascades host a wide variety of breeding birds, including bald eagles, osprey, harlequin ducks, spotted owls, marbled murrelets, and many species of  Neotropical migrants, such as Wilson’s warbler, Swainson’s thrush, and rufous hummingbird.
