Threat ImpactLow
Range Extent20,000-200,000 square km (about 8000-80,000 square miles)
Rank ReasonsCommon and still well distributed throughout the historical range in western Oregon, western Washington, and southwestern British Columbia.
Range Extent CommentsSouthwestern British Columbia, including Vancouver Island, south through western Washington to southwestern Oregon (Petranka 1998). Sea level to about 4100 ft (1250 m) (Stebbins 1985).
Occurrences CommentsRepresented by many and/or large occurrences throughout most of the range.
Threat Impact CommentsLogging is not a major threat because this species maintains thriving populations in young forests.
Ecology & Habitat
Habitat
Humid coniferous forests; damp talus slopes and shaded ravines. Found under rocks, logs, leaf litter, and other forest debris. On Vancouver Island, small individuals were found under small rocks and away from discrete cover objects in leaf litter and under moss more frequently than were larger individuals (Ovaska and Gregory 1989). Lays eggs on land in moist retreats.
Ecology
In British Columbia, mean distance between the two farthest captures over several months was 2.7 m (range up to 8-9 m) for adult males, which moved greater distances than did adult females and juveniles (Ovaska 1988); captures during the active season ranged from 0.3-1.16 per sq m, highest in spring (Ovaska and Gregory 1989).
Reproduction
In Oregon, breeds mainly from November-early March; courtship occurs in autumn on Vancouver Island (Ovaska and Gregory 1989). Female lays a clutch of about 10 eggs in the spring, broods them during the summer. Hatchlings appear in autumn. Female oviposits at intervals of 2 years or more; male produces sperm every year.
