Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor/s: Geoffrey Hammerson
Reviewer/s: Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Least Concern in view of its relatively wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Population: Many unthreatened populations are known.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: It is found along shady streams or stream seepages in wet rocky areas; talus slopes, moss-covered outcrops, often under rocks, logs, moss and leaf-litter. Animals may enter water to escape predators. Eggs are laid on land in moist crevices or cavities, where they develop directly without a larval stage.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): It is not strongly tied to old growth forest; it can be abundant in forests of all ages, though it is more likely present in logged forests when mature timber is present upstream (Corn and Bury 1991); hence logging is not a major threat to this species

Conservation Actions [top]

Conservation Actions: No conservation measures are needed for this species. It occurs in many protected areas.
