Score1 - Moderate: Generally 10,000-100,000 individuals.
CommentPopulation size is unknown for Montana, but due to its limited distribution is estimated to be <100,000 plants.
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
CommentIn Montana, the species is known from Carbon County, though may also occur in Big Horn County.
Area of Occupancy
Score1 - Moderate: Generally occurring in 11-25 Subwatersheds (6th Code HUC’s).
Score1 - Moderate: Species is restricted to a specific habitat that is more widely distributed or to several restricted habitats and is typically dependent upon relatively unaltered, good-quality habitat (C Values of 5-7).
ScoreNA - Rank factor not assessed.
CommentTrends are unknown, though habitat is generally stable and populations have probably not declined significantly.
Score0-1 - Low to Medium.
CommentThreats to the species' viability appear to be insignificant to low.
Score0 - Low Vulnerability: Species does not have any unusual or specific life history or biological attributes or limted reproductive potential which makes it susceptible to extirpation from stochastic events or other adverse impacts to its habitat and thus slow to recover.
CommentNo specific factors are known which are believed to increase the species' vulnerability.
