The Oregon slender salamander (Batrachoseps wrighti) is a species of salamander in the family Plethodontidae from the Northwestern United States.[2][3]

Distribution

The Oregon slender salamander is endemic to north-central Oregon, found particularly on the western slopes of the Cascade Range but also in some sites on the eastern slopes.[1][3][4]

Conservation

The Oregon slender salamander is threatened by habitat loss and classified as IUCN Red List Near threatened.[1] It is federally listed as a Species of Concern. The state of Oregon has listed it as sensitive in the Oregon Conservation Strategy.[5]

Habitat

The species' natural habitats are temperate forests of moist Douglas fir, maple, and red cedar woodlands in Oregon, to 910 metres (3,000 ft).[1] 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 much downed woody debris. They are found in large diameter decayed logs. They prefer habitats that have a closed canopy.[6] The species has also been found in a suburban landscape.[7]

Description

They have a long thin body and grow to 61 mm (2.4 in) in snout–vent length and 120 mm (4.7 in) in total length, though most individuals are smaller. They have four toes on the hind feet.[3]

Clutch size is 3–11 and the eggs are 4 mm in diameter.[3]

Behaviour

When found this species will coil its body up and remain motionless.[3]
