Committee on the Status of Endangered Wildlife in Canada (COSEWIC): Not at Risk (01May2000)
Comments on COSEWIC: Reason for designation: This large aquatic salamander is adversely affected by industrial contaminants and sedimentation of waterways, yet remains widespread and is, as we now know, abundant.

Status history: Designated Not at Risk in May 2000.

Population/Occurrence Delineation

Group Name: Proteid Salamanders (Waterdogs)

Use Class: Not applicable
Minimum Criteria for an Occurrence: Occurrences are based on evidence of historical presence, or current and likely recurring presence, at a given location. Such evidence minimally includes collection or reliable observation and documentation of one or more individuals (including larvae or eggs) in or near appropriate habitat where the species is presumed to be established and breeding.
Separation Barriers: Dams and impoundments (except N. maculosus); upland habitat
Separation Distance for Unsuitable Habitat: 1 km
Separation Distance for Suitable Habitat: 10 km
Separation Justification: These salamanders are strictly aquatic and cannot cross upland habitat. With the exception of N. maculosus, these salamanders are unlikely to successfully traverse an impoundment to reach suitable habitat downstream from a dam, unless the impoundment is very small. Because waterdogs do not climb and probably cannot use fishways, virtually all dams constitute a barrier to upstream movements.

Heavily silted or polluted streams may constitute a barrier or at least unsuitable habitat, depending on the severity of the conditions.

Based on data for the hellbender (Cryptobranchus allegheniensis), home ranges probably tend to be small, but information on periodic long-range movements, dispersal distances, and recolonization ability is not available.

The separation distance for unsuitable habitat reflects the nominal minimum value of 1 km. The 10-km separation distance for suitable habitat reflects the ease of movement and dispersal along riverine habitats and the likely low probability than locations separated by less than 10 km of suitable habitat would represent independent populations.

Inferred Minimum Extent of Habitat Use (when actual extent is unknown): .1 km
