The Oregon slender salamander (Batrachoseps wrightorum) is a species of salamander in the Plethodontidae family. Batracho-seps means "frog-lizard."


The Oregon slender salamander is endemic to the Northwestern United States specifically the western slopes of the Oregon Cascade Range.[1][2]

Its natural habitat is temperate forests of moist Douglas fir, maple, and red cedar woodlands in Oregon, to 3,000 feet (910 m).[1]

The species while noted to be an old growth obligate, was found in the suburban landscape.[3]


The Oregon slender salamander is threatened by habitat loss, it is an IUCN Red List Vulnerable species.[1] It is Federally listed as a Species of Concern. The state of Oregon has listed it as sensitive in the Oregon Conservation Strategy.[4]


They are typically found in old growth habitat, associated with late-successional Douglas- Fir forests. However they have been found in earlier succession forest with larger logs and lots of downed woody debris. They are found in large diameter decayed logs. They prefer habitats that have a closed canopy.[5]


They have four toes on the hind feet. The toes have slightly widened round tips. Juveniles are black to dark grey with mottled reddish dorsal strip, they have a black to silver speckled pattern on their under belly. They have a long thin body and are 14–64 mm long SVL.

The eggs while very rare to find are enclosed in a long thing strand of jelly and are 4 mm diameter.


When found this species will coil it's body up and remain motionless.
