Clouded salamanders are slim, relatively long-legged amphibians that are both terrestrial and arboreal; they live their lives in damp coastal mature forests, and are often found high above the ground in the forest canopy. They are members of the large family of plethodontid salamanders, which are characterized by reduced lungs and two grooves that extend from their nostrils to each side of the mouth. Adult clouded salamanders have smooth, moist skin that is brown to gray in color with metallic patches of gray, silver, pale gold, or bronze. At maturity, they are 1.8 to 3.0 inches in length from snout to vent, and 3.0 to 5.1 inches in total length. They have long, squared-off toes and strong, prehensile tails (capable of grasping) adapted for climbing. Males have broader, more triangular heads than females. They have 16 costal grooves on their sides between the front and back legs. Juveniles are similar in appearance to adults, with an orange stripe that runs down the center of their backs. Similar species to clouded salamanders are the wandering salamander and the black salamander. Black salamanders have toes with rounded tips, whereas clouded salamanders have toes that are squared off. The clouded salamander and wandering salamander were separated into two species in 1998 based on genetic evidence, and are difficult to distinguish in the field. The range of these two species overlaps in a small portion of northwestern California. Outside of this area of overlap, geographic location is the best way to distinguish between the two species. The clouded salamander is endemic to Oregon and extreme northern California.

Ecoregions

Special needs

Clouded salamanders do not have an aquatic life history, and occur in terrestrial and arboreal forest habitats in western Oregon. They are often found in large decaying logs, particularly of Douglas fir, but can also be found in talus, crevices, and other debris. In forest interiors, the clouded salamander may occur in standing or dead trees in cavities or in nests of other arboreal species including red tree vole. The species occurs in disturbed areas, provided that there is enough woody debris to provide necessary shelter from high temperature or low humidity conditions.

Limiting factors

Clouded salamanders have a restricted range, occurring primarily in Oregon. The availability of microhabitat features, namely large logs, that meet temperature and moisture requirements is believed to be a key limiting factor. Connectivity of habitat for this species is affected by forest management practices and land-use change, and the species may be slow to recover following declines in habitat quality or extent. Climate change may further exacerbate threats to this species. High severity wildfire may result in habitat loss for arboreal populations.

Conservation actions

• Retain patches of intact habitat, including large logs, during forest management activities
• Identify areas of high salamander density as source populations to support dispersal and recolonization
• Provide adequate riparian buffer strips (see Partners in Amphibian and Reptile Conservation recommendations) and downed wood debris
