Scientific Name: Eurycea wallacei (Carr, 1939)
Common Name(s):
English Georgia Blind Salamander
Haideotriton wallacei Carr, 1939

Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Geoffrey Hammerson
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Vulnerable, because its Extent of Occurrence is less than 20,000 km2 and its Area of Occupancy is less than 2,000 km2, its distribution is severely fragmented, and there is probably a continuing decline in the quality of its habitat.

Geographic Range [top]

Range Description:This species can be found throughout the Marianna Lowlands-Dougherty Plain physiographic region, in the states of Florida and Georgia, USA. It is known from several caves in Jackson County, Florida; also occurs in Dougherty and Decatur counties, Georgia. It occurs in at least two sites in Georgia and at least 11 sites in Jackson County, Florida.
Countries occurrence:
United States

Population [top]

Population:The total adult population size is unknown, and the current trend is also unknown. In the period 1969-1992, populations seemed fairly abundant, in spite of heavy collecting in one or two localities (Means 2005).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is a resident of the Marianna Lowlands (Dougherty Plain) karst aquifer; it is found in subterranean streams and clear pools in caves and deep wells. It may sometimes leave water and climb limestone walls of caves. It may ultimately depend on guano from associated bat populations.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): Threats include pollution from agricultural runoff and fluctuations in the water table due to impoundments and human use. Over-collecting for science or by herp enthusiasts is a potential threat.

Conservation Actions [top]

Conservation Actions: Caves in the Marianna Caverns State Park are protected. Conservation measures include: monitoring known populations and water quality; limiting human intrusion into caves by means of signs, fences, or gates as appropriate; protecting associated bat populations; and limiting pollution and water table fluctuations. Populations cannot be considered adequately protected just because cave mouths are protected.
