The Cascade torrent salamander is a small, secretive amphibian of the coldest, cleanest water in the forest. Adults reach only about four inches long, with a tan to brown back peppered with black spots and pale flecks, a short rounded snout, big prominent eyes, and a bright yellow belly. Adult males have squared-off lobes around the vent, a feature found only in torrent salamanders.
These salamanders live in and beside cold, fast, clear water: headwater creeks, seeps and the splash zones of waterfalls, usually under a thick forest canopy. Their lungs are tiny and they breathe mostly through their skin, which makes them very sensitive to warm water, silt and drying out. Larvae stay in the water for years, about four to five before they transform. Adults eat small aquatic and streamside animals such as stoneflies, beetles and snails, and they move very little, often staying within a few meters for months.
The species lives only on the west slope of the Cascades, from just north of Mount St. Helens to northeastern Lane County, so Mt. Hood sits near the middle of its small range. Logging, roads and a warming climate threaten it by heating streams and clogging gravel with silt. If you find one under a streamside rock, look without handling it, then set the rock back exactly as it was.
How to identify it
A small salamander up to about 4 inches long, with a tan to brown back covered in black spots and whitish flecks, a short rounded snout, large eyes, and a bright yellow to orange-yellow belly with few spots. Adult males have squared vent lobes.
Look-alikes
Woodland salamanders and ensatinas have a groove from nostril to lip, and ensatinas have a pinched tail base; rough-skinned newts are stockier with thick, often rough skin. Other torrent salamanders look nearly the same, but the Cascade species is the only one in the Mt. Hood area.
Habitat
Permanent, cold, clear headwater streams, seeps and waterfall splash zones with silt-free gravel, usually in older, shaded conifer forest on the west slope of the Cascades. Adults may move into wet forest near streams during rainy periods.
