NatureServe Global Conservation Status Factors

Range Extent Comments: Nearly circumpolar. Northern North America. Alaska to Labrador south to Oregon, Montana, Iowa, Michigan, and West Virginia, with disjunct populations in Wyoming, New Mexico, and Utah. Europe, Asia. (Welsh 1974; Porsild and Cody 1980; USDA NRCS 2012).

Number of Occurrences: 81 to >300
Number of Occurrences Comments: More than thirty collections in Canada. Very widespread, nearly circumpolar distribution. Mickel says frequent in northern North America, Europe, and Asia.

Population Size Comments: Usually rare and scattered (Hulten, 1968), very local and restricted to limestone outcrops (Porsild and Cody, 1980).

Overall Threat Impact Comments: Human disturbance is a low-level threat, as a population occurs along the trail to a highly-used cave. (Southern Appalachian Species Viability Project 2002).
