From the IUCN Red List Species Account:


Range Description

This species can be found in Eastern North America. It is also found in Southern Quebec and eastern Ontario south to northern Virginia, eastern West Virginia, and central Ohio; isolated populations in southern Labrador (Jacobs 1987, Conant and Collins 1991, Sever 1999).

Habitat and Ecology

It can be found in rocky brooks, springs, and seepages; animals may disperse into wooded terrestrial habitats in wet warm weather. Bahret (1996) documented a breeding population in an acidic, fish-free lake in New York; occurred to depths of 19.5m. Adults hide under objects in or near water. In New York, rarely found on soils of low pH (Wyman 1988, Wyman and Jancola 1992). Eggs typically are laid on underside of submerged rocks, logs, or aquatic plants. Bahret (1996) found eggs in a lake at depths of 9.0-13.5 m, on the topmost leaves of water moss, far from shore and from surface drainage inlets.


Total adult population size is unknown but surely exceeds 100,000. Many stable populations.

Population Trend


Major Threats

No major pervasive threats. Often common in and along streams in semi-cleared areas and in second-growth woods surrounded by suburban areas (G. Hammerson pers. obs), though Petranka (1998) stated that the species is often absent from urban areas or highly disturbed landscapes such as result from intensive timbering, land clearing, stream pollution, and stream siltation.

Conservation Actions

In minimal need of protection (Petranka 1998).

Red List Status

Least Concern (LC)
