Range Extent Comments: Coastal Plain, North Carolina to Lake Okeechobee, Florida, west to eastern Texas; range shown in Conant and Collins (1991) has been reduced somewhat by the recognition of yellow morph populations as distinct species (Eurycea chamberlaini) (Harrison and Guttman 2003). Record from Barry County, Missouri, reported in 1945, has not been substantiated by more recent collections; Johnson (1987) did not include this species as a part of the Missouri herpetofauna.

Number of Occurrences: 81 to >300
Number of Occurrences Comments: Many occurrences.

Population Size: 10,000 - 1,000,000 individuals
Population Size Comments: Total adult population size is unknown but presumably exceeds 10,000. Moderately abundant throughout the range (Petranka 1998).

Number of Occurrences with Good Viability/Integrity: Many to very many (41 to >125)
Viability/Integrity Comments: Probably many occurrences have good viability.

Overall Threat Impact: Medium
Overall Threat Impact Comments: In minimal need of protection, though many populations likely have been eliminated through loss of wetlands (Petranka 1998).

Short-term Trend: Relatively Stable (<=10% change)
Short-term Trend Comments: No data but likely stable in extent of occurrence and probably stable to slightly declining in population size, area of occupancy, and number/condition of occurrences.

Long-term Trend: Decline of <30% to increase of 25%
Long-term Trend Comments: Stable in extent of occurrence, likely has declined less than 25% in population size, area of occurrence, and number/condition of occurrences.

Intrinsic Vulnerability: Moderately vulnerable

Environmental Specificity: Narrow. Specialist or community with key requirements common.

Reproduction Comments: Lays up to about 60 eggs singly or in small clusters, late fall to early winter. Female attends eggs. Larvae hatch in 30-40 days, metamorphose in spring or early summer. Sexually mature in first year.
Non-Migrant: Y
Locally Migrant: Y
Long Distance Migrant: N
Mobility and Migration Comments: Distinct migrations between breeding and nonbreeding habitats occur in some areas.
Riverine Habitat(s): SPRING/SPRING BROOK
Lacustrine Habitat(s): Shallow water
Palustrine Habitat(s): FORESTED WETLAND, HERBACEOUS WETLAND, Riparian, TEMPORARY POOL
Special Habitat Factors: Benthic, Fallen log/debris
Habitat Comments: Low swampy areas, margins of pine savanna ponds, bottomland forests. Hides under logs or other debris during day. In Alabama, peaks in terrestrial activity coincided with late fall-early winter rains (Trauth 1983). Lays eggs in seepage areas or near the edge of shallow ponds on undersides of logs or leaves, under or on sphagnum or pine needles, or on rootlets beneath logs.
Adult Food Habits: Invertivore
Immature Food Habits: Invertivore

Adult Phenology: Nocturnal

Management Requirements: Intensive site preparation or clearcutting of bottomland forest, and stream channelization or impoundment, should be avoided.
Population/Occurrence Delineation
Help
Group Name: Aquatic/Wetland Plethodontid Salamanders

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: Busy highway, especially with high traffic volume at night; other totally inappropriate habitat that the salamanders cannot traverse.
Alternate Separation Procedure: Separation distance for stream-dwelling species along riverine corridors: 10 stream km. Separation distance for other freshwater aquatic and wetland habitats: 3 km. Separation distance for upland habitat: 1 km.
Separation Justification: These salamanders rarely successfully cross roadways that have heavy traffic volume at night, when most movements occur. Salamanders in this Specs Group, except strictly subterranean species, tend to be able to traverse upland habitat when conditions are wet, and generally they can pass through atypical wetland and aquatic habitats to reach another patch of suitable habitat. However, Grover and Wilbur (2002) created replicated seeps at distances of 3, 15, and more than 30 m from streams or natural seeps and found that Desmognathus fuscus and Gyrinophilus porphyriticus colonized the new seeps at 3 m and 15 m but were rare or absent at new seeps more than 30 m from the nearest stream or natural seep.

Although these specifications do not include rivers as barriers, Adams and Beachy (2001) documented morphological variation among populations of Gyrinophilus porphyriticus in the southern Appalachian Mountains and found patterns "consistent with the hypothesis that large rivers restrict sizable gene flow." Large rivers probably function at least as unsuitable habitat for many species in this Specs Group.

Compared to larger ambystomatid salamanders, the movements of plethodontids are poorly documented, but home ranges likely tend to be very small, on the order of a few meters to a few dozen meters in length or diameter. Yet, on occasion, dispersing individuals likely travel at least several hundred meters, and stream-dwelling species likely disperse much farther along riverine corridors. Over a number of years, it is likely that these salamanders can spread multiple kilometers through suitable habitat.

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