- 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.

General Description
Tree up to ca. 50 m tall with a conical crown and branches that bend down and then out. Bark gray with reddish furrows, becoming brown in older trees. Leaves 2–4 cm long, blunt-tipped, borne in a single plane opposite each other on the twigs, erect. Stomates on underside only. Seed cones usually green, 6–11 cm long (
