Justification:
Pyganodon lacustris has been assessed as Least Concern due to its widespread distribution. Further research is recommended regarding population trends and threats impacting this species.

Geographic Range [top]

Range Description: This species is endemic to the United States of America and is found in Illinois, Ohio, Michigan and New York (Hoeh 1990, NatureServe 2009), as well as Indiana and Wisconsin (A. Bogan pers. comm. 2010). However, this species is likely to occur in the Great Lakes and into Canada, but the specific range has not been assessed (NatureServe 2009).

Population [top]

Population: There is no population information available for this species (NatureServe 2009).
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This species is rarely found in rivers and is predominantly a lake dweller, where it favours muddy bottom substrata (Hoeh and Burch 1989 in NatureServe 2009).
Systems: Freshwater

Threats [top]

Major Threat(s): There is no specific threat information available for this species; however, it is likely that this species is being impacted upon by general freshwater threats within this region.

Conservation Actions [top]

Conservation Actions: There are no specific conservation measures in place for this species. Further research into the population size, distribution and trends is suggested as these data are lacking. Also an investigation into the threats this species may be facing is recommended. Monitoring should be carried out because if threat levels do increase, significant population declines may occur in the future. Williams et al. (in press, from K. Cummings pers. comm. 2010) list this species as being currently stable according to the AFS assessment.
