Rank Reasons
Draba subalpina is known only from southwestern Utah in soil in meadowland or forest. The species is evidently one of the more widespread and frequently encountered endemics on the Claron Formation limestone. In 1979, potential threats were limestone exploitation, potential railroad construction and mineral exploration; it is not known if these threats remain.
Range Extent Comments
Occurs on the Markagunt, Pausaugunt, and Table Cliff plateaus in southwestern Utah; also known disjunctedly from the Pavant Range in Millard County and near the northern end of the Tushar Mountains in Sevier County; from Bryce Canyon and Cedar Breaks (Stone 1998).
Threat Impact Comments
Potentially threatened by limestone exploitation, potential railroad construction and mineral exploration (Welsh 1979).
Ecology & Habitat

Habitat

Ponderosa pine, pinyon-juniper, Douglas fir, bristlecone pine, and spruce-fir communities on the pink and white limestone members of the Claron Formation (Welsh et al. 2008).
