Rank Reasons

Phacelia lyallii is known from the southern Canadian Rockies south to Montana and a few locations in east central Idaho. The plant is also rare in extreme southeastern British Columbia. Its distribution is mainly confined to western Montana and Alberta. The remoteness and disturbed nature of the plant's habitat protect this species, although the potential use by wild sheep and goats needs to be determined.

Range Extent Comments

From extreme southeastern British Columbia, east to southwestern Alberta and south to Montana and a few locations in Lemhi County, in east-central Idaho (Spahr, R., L. Armstrong, D. Atwood, and M.Rath 1991 and Douglas, Straley, and Meidinger 1990).

Occurrences Comments

Only a few populations are known in Idaho (Spahr, R., L. Armstrong, D. Atwood, and M.Rath 1991).

Threat Impact Comments

The remoteness and disturbed nature of the plant's habitat seems to protect this species. Potential use by wild sheep and goats needs to be determined (Spahr, R., L. Armstrong, D. Atwood, and M.Rath 1991).

Ecology & Habitat

Habitat

Subalpine to alpine talus and rock crevices only from quartzite rocks (Spahr, R., L. Armstrong, D. Atwood, and M.Rath 1991). Found on talus slopes and in rock crevices on north- and east-facing slopes near or above timberline (Lackschewitz 1991).
