State Rank Reason (see State Rank above)
See rank details.
- 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
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).
Trends
Score0 - Stable or Increasing: Population size, range, and/or available habitat stable, increasing or fluctuating in the recent past (approximately 30 years).
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 - 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
0 total points scored out of a possible 19.
General Description
Evergreen trees up to 60 m tall with spreading branches and narrow to broadly conical crowns. Bark of older trees thick, furrowed and gray with reddish brown between furrows. Leaves yellow- to blue-green, single, spirally arranged and spreading, 15–25 mm long, stomates lacking on upper surface. Leaf buds conical. Seed cones narrowly ellipsoidal, 3–6 cm long, maturing the first season and shed entire. Scales broadly rhombic, stiff, pubescent, subtended by a longer 3-lobed bract. Seeds winged. Our plants are var. glauca (
