Other Statuses

Canadian Species at Risk Act (SARA) Schedule 1/Annexe 1 Status: SC (05Jun2003)
Committee on the Status of Endangered Wildlife in Canada (COSEWIC): Special Concern (27Nov2009)
Comments on COSEWIC: Reason for designation: A highly disjunct Atlantic Coastal Plain species restricted in Canada mainly to two connected, extensive, lakeshore populations in southern Nova Scotia. Comprehensive new surveys and other information indicate that the risk of extinction for this species is less than previously thought. Its lakeshore habitat has been subject to slow but steady loss and decline in quality due to cottage and residential development for 30 to 40 years. Losses are likely to continue through the foreseeable future with new development and intensification of existing development, but the proportion of habitat currently developed is still low and the species' locally widespread occurrence and asexual reproduction mitigates the threat of extinction in the short term.
Assessment Criteria: not applicable
Status History: Designated Threatened in April 1994. Status re-examined and confirmed in May 2000. Status re-examined and designated Special Concern in November 2009.

NatureServe Global Conservation Status Factors

Overall Threat Impact Comments: Land-use conversion and habitat fragmentation present low-level threats to this species (Southern Appalachian Species Viability Project 2002).
