Status in the Cedar

Larch Mountain Salamander.

First Larch Mountain Salamander found in the Cedar River Municipal Watershed.

Stream-breeding amphibians documented in the Cedar River Municipal Watershed include tailed frog (Ascaphus truei) and pacific giant salamander (Dicamptodon tenebrosus). Both these species are common and found throughout the watershed. Also common around streams, although they lay eggs in riparian and upland forest habitat rather than in streams, are the more terrestrial amphibians, western red-backed salamanders (Plethodon vehiculum) and ensatinas (Ensatina eschscholtzii).

The larch mountain salamander (Plethodon larselli) lives in talus slopes typically away from streams. In 2011, this species was found for the first time in the Cedar River Municipal Watershed. Read the report Larch Mountain Salamander Detected in the CRMW (pdf). This record represents one of the northernmost observations of this species in Washington State.

Two other amphibian species are listed in the HCP, but historic distribution records suggest their presence is unlikely in the watershed. These include the cascade torrent salamander (Rhyacotriton cascadae) and Van Dyke’s salamander (Plethodon vandykei), both heavily associated with small streams.

No formal surveys documenting the distribution of stream-breeding amphibians have been conducted in the watershed.
