Score1 - Moderate: Generally 10,000-100,000 individuals.
CommentPopulation size is imprecisely known, though available data supports an estimate of at least 10,000 plants and the total could easily be much larger.
Score3 - Local Endemic or Very Small Montana Range: Generally restricted to an area <10,000 sq. miles (equivalent to the combined area of Phillips and Valley Counties) or <6 Sub-basins (4th code watersheds) Range-wide OR limited to one Sub-basin in Montana
Area of Occupancy
Score1 - Moderate: Generally occurring in 11-25 Subwatersheds (6th Code HUC’s).
Score1-2 - Moderate to High.
CommentLimited to limestone or calcareous talus, scree or cliffs in the alpine.
Score0-1 - Stable to Minor Declines:
CommentTrend are undocumented, though populations are likely stable or experiencing only minor declines. Monitoring data are needed.
Score0-1 - Low to Medium.
CommentThreats appear to be minimal and would primarily be limited to potential impacts related to climate change.
Score1 - Moderate Vulnerability: Specific biological attributes, unusual life history characteristics or limited reproductive potential makes the species susceptible to extirpation from stochastic events or other adverse impacts to its habitat and slow to recover.
CommentSpecific life history characteristics and limitations are unknown.
