The park's extensive and diverse wetlands support a relatively high number of amphibians. Of 11 confirmed species, fourare uncommon or rare. Imperiled due to habitat loss, Cope's giant salamander and the Columbia torrent salamanders are aquatic inhabitants of small cold streams. Pacific giant salamanders live in the park's small streams and adjacent moist forests. Northern red-legged frog, a federal species of concern, inhabit park forests and freshwater wetlands.
