The park's most audible amphibians serenade springtime visitors from their catchment and water-filled ditches throughout the area. The Pacific treefrog spends most of its time toe-padding the wet lengths of branches and shrubs in the temperate rainforest. During spring breeding, treefrogs descend to the forest floor and into the water to join a cacophony of frog symphonics!
Red-legged frogs are also resident forest-dwelling amphibians. They flourish in damp coastal forest and never venture far from standing water. Red-legged frogs, like Pacific treefrogs, are members of the spring breeding chorus. Their low-pitched croaks are sung underwater and may not be noticed under the din of the more vocal treefrogs.
Rough-skinned newts and northwestern salamanders are found among the decomposing deadfall and leaf litter characteristic of coastal forests. Also resident, although not as dependent upon wet environments, are terrestrial western red-backed salamanders. Still requiring moisture, they can be found under fallen logs and mosses in damp, but not wet, locations. Another resident amphibian is the clouded salamander. It is a very nimble tree-climber, most active at night.
