Population Size
Score0-1 - Moderate to Large: Population size is imprecisely known but is believed to be >10,000 individuals.
Range Extent
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
Score2 - Low: Generally occurring in 4-10 Subwatersheds (6th Code HUC’s).
Environmental Specificity
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).
Trends
Score0-1 - Stable to Minor Declines:
CommentTrends are undocumented, but it does not appear that the species has experienced moderate or severe declines.
Threats
Score0 - Low: Impacts, if any, to the species are expected to be minor or insignificant (affecting <10% of populations) in severity, scope and immediacy.
CommentImpacts to some populations are possible from various, localized activities but the scope of any impacts would be very low.
Intrinsic Vulnerability
Score0-1 - Low to Moderate Vulnerability.
Raw Conservation Status Score

6 to 9 total points scored out of a possible 19.
