Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA CAUDATA PLETHODONTIDAE

Scientific Name: Plethodon cinereus
Species Authority: (Green, 1818)
Common Name/s:
English Redback Salamander
Taxonomic Notes: Some published literature on this species actually pertains to Plethodon serratus, which was given species status in mid-1970s.

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)
Justification:
Listed as Least Concern in view of its 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.

Geographic Range [top]

Range Description: This species can be found in North America in Minnesota and western Ontario to southern Quebec and Newfoundland, south to North Carolina and northeastern Tennessee (Conant and Collins 1991, Petranka 1998).

Population [top]

Population: This is an extremely abundant species. Total adult population size is unknown but certainly exceeds many millions of individuals. Thousands of localities are known.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: It can be found in damp microhabitats in wooded areas; inside logs, under leaf-litter, or under surface objects during day. Goes underground during freezing or hot, dry weather. In New York, tended to be absent where soil pH was less than 3.8; much more abundant in beech forest than in hemlock forest (Wyman 1988, Wyman and Jancola 1992, Frisbie and Wyman 1992). It occurs in altered habitats where damp microhabitats remain, such as in urban and suburban gardens. Lays eggs in cavity in log or stump or under rock or other objects on ground, where they develop directly without a larval stage.
Systems: Terrestrial

Threats [top]

Major Threat(s): Intensive timber harvest causes major declines in abundance (deMaynadier and Hunter 1995). Negative impacts of intensive timber harvesting extend at least 25-35m into uncut forest (deMaynadier and Hunter 1998). Roads negatively impact salamander abundance in roadside habitat and might serve as partial barriers to movement (deMaynadier and Hunter 2000). Animals have been exported from the United States to Canada as part of the international pet trade. However, none of these factors pose serious threats to the global population, and the species can adapt to certain modified habitats.

Conservation Actions [top]

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