- Details on Status Ranking and Review
Population Size
Score0 - Large: Generally >100,000 individuals.
Range Extent
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).
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 unknown, though populations are likely stable or experiencing only minor declines.
Threats
Score0-1 - Low to Medium.
Intrinsic Vulnerability
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.
Raw Conservation Status Score
Score
1 to 3 total points scored out of a possible 19.
General Description
Perennial with fibrous roots. Stems erect, 5–50 cm high, expanding with maturity. Leaves petiolate, the blades broadly cordate, 3–7 cm wide, deeply palmately divided into ca. 5 toothed or lobed, ovate segments. Flowers solitary; sepals 5 to 7, petal-like, white, 1–2 cm long; petals inconspicuous, stamen-like; stamens many; pistils 10 to 20. Fruit a hemispheric cluster of cylindrical several-seeded follicles 8–15 mm high, opening at the top (
