Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012
Date Assessed: 2012-03-05
Assessor(s): Cummings, K. & Cordeiro, J.
Reviewer(s): Bohm, M., Collen, B. & Seddon, M.
Contributor(s): Richman, N., Dyer, E., Soulsby, A.-M., Whitton, F., Kasthala, G., McGuinness, S., Milligan, HT, De Silva, R., Herdson, R., Thorley, J., McMillan, K., Collins, A., Offord, S. & Duncan, C.
Justification:
Lampsillis fasciola has been assessed as Least Concern because it has a wide range across the USA. Some populations have declined in the northern and southern parts of its range and it is critically imperiled, or vulnerable, in Ontario, New York, Illinois, Michigan, North Carolina, Georgia, Indiana and Ohio. However, the main central populations are considered to be stable with no major threats impacting the population.

Geographic Range [top]

Range Description:Clarke (1981) cites the range of this species as the Great Lakes drainage in the tributaries of Lake Michigan, Lake Huron, Lake St. Clair, and Lake Erie, and the Ohio-Mississippi drainage south to the Tennessee River system. Strayer and Jirka (1997) list distribution as the Ohio River basin, and in the tributaries of Lake St. Clair, Lake Erie, southern Lake Huron, and southwestern Lake Ontario. The only reproducing populations left in Canada are in Ontario on the Grand and Maitland Rivers (Metcalfe-Smith and Cudmore-Vokey 2004). It probably still persists in the Upper, North, and Middle Thames River in Ontario but may no longer be successfully reproducing (Cudmore et al. 2004). The species has a large extent of occurrence in excess of 200,000 km2.
Countries occurrence:
Native:
Canada (Ontario); United States (Alabama, Florida, Georgia, Illinois, Indiana, Kentucky, Michigan, Mississippi, Missouri, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia)
