Occurrences Comments
Baxter (1987) cites occurrences in Alaska in the Aleutian Islands with potential occurrences in the North Gulf Coast and southeastern part of the state. Forsyth (2005) documented it in the Upper Fraser Basin of central British Columbia in several open mixed-wood forests and pure stands of trembling aspen. Forsyth (2005) documented it in British Columbia in the Peace River- Northern Rockies region within the Sub-boreal Spruce and perhaps Engelmann Spruce- Subalpine Fir zones at a single site near Mackenzie. Most recently, it was discovered in the Ktunaxa Traditional Territory in southeastern British Columbia (which extends from near Canada - U.S. border north to about 50 km north of Cranbrook) (Ovaska and Sopuck, 2009).
