Details on Status Ranking and Review
Score 1 - Moderate: Generally 10,000-100,000 individuals.
CommentEstimated as population levels from specimen collections are largely unknown. Range Extent
Score 2 - 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
Score 1 - Moderate: Generally occurring in 11-25 Subwatersheds (6th Code HUC’s). Environmental Specificity
Score 1 - 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
