|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
|Facilitator/Compiler(s):||Green, C., Sharp, D. & Garcia Moreno, J.|
Listed as Least Concern in view of the large extent of occurrence, large number of subpopulations and locations, and presumed large population size.
|Previously published Red List assessments:||
|Range Description:||This species is found in North America from southeastern Quebec to Lake Winnipeg, south through Great Lakes region and New England to northern Indiana and New Jersey. Several apparently disjunctive populations occur around the periphery of the range (e.g., see Brownlie (1988) for Nova Scotia record). Hybridises with A. jeffersonianum over a large area south of this range.|
Native:Canada (Labrador, New Brunswick, Nova Scotia, Ontario, Prince Edward I., Québec); United States (Connecticut, Illinois, Indiana, Iowa, Maine, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Ohio, Vermont, Wisconsin)

|Population:||The total adult population size is unknown, but it probably exceeds 100,000.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||In New England and New Jersey, this species generally is associated with lowland swamps and marshes and surrounding uplands with sandy or loamy soils (Nyman et al. 1988, Klemens 1993). It may occur in overgrown pastures. Adults spend much time underground. Eggs are attached to submerged sticks or the bottom of shallow forest ponds and pools. A free-living larval stage is present. At Isle Royale, Michigan, breeding sites include splash pools on exposed rocky shorelines (Van Buskirk and Smith 1991). In northern Minnesota, successful reproduction in acidic bog water either does not occur or is a rare event (Karns 1992).|
|Use and Trade:||There are no reports of this species being utilized.|
|Major Threat(s):||The biggest threat is loss and degradation of habitat as a result of conversion to agricultural and urban use. Roads negatively impact salamander abundance in roadside habitat (deMaynadier and Hunter 2000). Increased acid deposition is a potential threat.|
The species would benefit from increased protection of lowland forested wetlands.
Research is needed in population size, trends and taxonomy.
