Score1 - Moderate: Generally 10,000-100,000 individuals.
CommentPopulation size is unknown for Montana, but due to its sparse distribution is estimated to be <100,000 plants.
Score1 - Peripheral, Disjunct or Sporadic Distribution in MT: Widespread species that is peripheral, disjunct or sporadically distributed within MT such that it occurs in <5% of the state (<7,500 sq. miles or the combined area of Beaverhead and Ravalli Counties) or is restricted to 4-5 sub-basins.
CommentPeripheral and sporadically distributed in northwest Montana.
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).
Score0-1 - Stable to Minor Declines:
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.
