Rank Reasons

Occurs in Montana, Wyoming, Colorado, British Columbia and Alberta. Hiking may be a threat to this species.

Range Extent Comments

Occurs from southern British Columbia and Alberta to northwestern Montana, with disjunct populations in west-central Wyoming and central Colorado.

Occurrences Comments

Five occurrences are documented in three counties in Colorado (CNHP 1998). There are ten documented specimens from Alberta. Most of these are from the 1980's (Alberta NHIC 1998). Montana Heritage (MTNHP 1998) reports between 6-100 occurrences documented by 1984, when it was taken off their list. In Wyoming there are at least 2 occurrences. It appears locally abundant in British Columbia, based on its S3 rank.

Threat Impact Comments

Hiking and mining may be concerns for this species (CNHP 1998). The Montana Natural Heritage Program reports that all of the occurrences in MT are pretty well protected (1998).
