- Details on Status Ranking and Review
Score0 - Large: Generally >100,000 individuals.
Score0 - Widespread species within Montana (occurs in 5% or more of the state or generally occurring in 6 or more sub-basins.) as well as outside of Montana.
Area of Occupancy
Score0 - High: Occurs in >25 Subwatersheds (6th Code HUC’s).
Score0 - Low: Species is a generalist that occurs in a variety of habitats and/or is tolerant of disturbed or degraded habitats (C -Values of 1-4).
CommentTolerant of disturbance and nutrient enrichment.
Score0 - Stable or Increasing: Population size, range, and/or available habitat stable, increasing or fluctuating in the recent past (approximately 30 years).
Score0 - Low: Impacts, if any, to the species are expected to be minor or insignificant (affecting <10% of populations) in severity, scope and immediacy.
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.
