Tree to 10(-20) m tall, with trunk to 0.6(-1.7) m in diameter, but often dividing into several trunks at or near the base. Bark light brown, becoming shallowly furrowed between irregularly shaped and uneven small plates. Crown egg-shaped when young, progressively broadening with age, with numerous, upwardly angled branches from the base moderately clothed with foliage. Twigs hairless, light reddish brown at first, becoming light gray. Buds 5-10 mm long, resinous. Needles in bundles of (one or) two (or three), each needle 2-4.5(-6) cm long, gently curved, stiff, and sticking together, lasting 4-9 years, bright light green to bluish green. Individual needles with lines of stomates on both the inner and outer faces, an undivided midvein, and two resin canals touching the epidermis of the outer face about midway between the corners and the midline. Sheath 5-7 mm long, curling back and soon shed. Pollen cones 7-10 mm long, yellowish brown.

 Conservation Status

Red List Category & Criteria: Least Concern

(Despite evidence of some decline due to clearance of pinyon-juniper woodland in favour of pastureland, and extensive recent dieback associated with repeated droughts and pine bark beetle infestations, the extent of occurrence and area of occupancy of Pinus edulis are still well beyond any thresholds for a threatened category and it is therefore assessed as Least Concern)
