- Details on Status Ranking and Review
Population Size
Score0-1 - Moderate to Large: Population size is imprecisely known but is believed to be >10,000 individuals.
Range Extent
Score2 - Regional or State Endemic or Small Montana Range: Generally restricted to an area <100,000 sq. miles (equivalent to 2/3 the size of Montana or less) or Montana contributes 50% or more of the species’ range or populations OR limited to 2-3 Sub-basins in Montana.
Area of Occupancy
Score0 - High: Occurs in >25 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
ScoreNA - Rank factor not assessed.
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.
Intrinsic Vulnerability
Score0-1 - Low to Moderate Vulnerability.
Raw Conservation Status Score
Score
3 to 5 total points scored out of a possible 16.
