From the IUCN Red List Species Account:

 

Range Description

This species can be found throughout the eastern USA and adjacent southern Canada; west to Minnesota, eastern Kansas, and eastern Texas (Petranka 1998). There are thousands of occurrences.

Habitat and Ecology

Adults and larvae inhabit ponds, swamps, and quiet stream pools. Animals may burrow into mud if pond dries. Efts and sometimes adults (i.e. over wintering ones) inhabit wooded areas (terrestrial eft stage lasts 2-7 years). The adults are generally permanently aquatic in northeastern USA, but may leave ponds in summer or fall in some areas (e.g. montane Virginia). Eggs are attached to submerged vegetation.

Population

It is widespread and abundant with a stable population. It might have increased as creation of farm ponds augmented available habitat (Petranka 1998). It could be increasing with increasing beaver populations (Petranka 1998).

Population Trend

stable

Major Threats

Roads negatively impact salamander abundance in roadside habitat and might serve as partial barriers to movement (deMaynadier and Hunter 2000). Introduced Bluegill Sunfish might cause declines in larval abundance (Smith et al. 1999). However, on a range-wide basis, the species has no major threats

Conservation Actions

Conservation Actions
It occurs in many protected areas. 

Research Needed
Monitoring and research on population trends are lacking.

Red List Status

Least Concern (LC)

Rationale

Listed as Least Concern in view of the large extent of occurrence, large number of sub-populations and localities, large population size and use of a wide range of habitats.
