Ponderosa Pine - Pinus ponderosa
(see State Rank Reason below)
State Rank Reason (see State Rank above)
Widespread and abundant across low-elevations in most of Montana.
- 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).
ScoreNA - Rank factor not assessed.
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.
Raw Conservation Status Score
0 points scored out of a possible 16 (Rarity factors and threats only).
Large trees to 65 m tall with an open, rounded crown and spreading branches. Bark of old trees thick, furrowed, covered with scales that resemble pieces of a jigsaw puzzle. Leaves yellow-green, 7–25 cm long, 2–3 per fascicle, clustered on branch ends. Seed cones broadly ovoid, 7–15 cm long. Scales thick with a terminal prickle. Seeds with a conspicuous wing. Our plants are var. scopulorum (Lesica et al. 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX
