Sugar pine is notable for having the longest cones of any conifer, mostly 10–50 cm (4– 19 + 3 ⁄ 4 in) long, [2] [5] exceptionally to 60 cm (23 + 1 ⁄ 2 in) long [citation needed] (although the cones of the Coulter pine are more massive); their unripe weight of 1–2 kilograms (2.2–4.4 lb) makes them perilous projectiles when chewed off ...
Each segment, or "scale", of the cone is tipped with a talon-like hook. Coulter pines produce the largest cones of any pine tree species and people are advised to wear hardhats when working in Coulter pine groves, although the slender cones of the sugar pine are longer. The large size of the cones, combined with the claw-like scales, has earned ...
In general, this classification emphasized cone, cone scale, seed, and leaf fascicle and sheath morphology, and species in each subsection were usually recognizable by their general appearance. Pines with one fibrovascular bundle per leaf, (the former subgenera Strobus and Ducampopinus ) were known as haploxylon pines , while pines with two ...
Once the pine cones are collected, they're brought to a network of nurseries, where the seeds are extracted and grown into seedlings. One million seedlings will plant about 4,500 acres of new forest.
Cones occur in one to five clusters. [4] The cones are strongly reflexed down the branch, 5-to-10-centimetre-long (2.0 to 3.9 in) long; the scales are stiff, thin on the side of the cone facing the stem, but greatly thickened on the side facing away and with a stout 5 to 12 millimetres (0.20 to 0.47 in) spine; both features adaptive to minimise ...
Unusually for a pine, the cones normally point forward along the branch, sometimes curling around it. That is an easy way to tell it apart from the similar lodgepole pine in more western areas of North America. The cones on many mature trees are serotinous. They open when exposed to intense heat, greater than or equal to 50 °C (122 °F). [16]

Pinus jeffreyi occurs from southwest Oregon south through much of California (mainly on the eastern side of the Sierra Nevada), to northern Baja California in Mexico. It is a high-altitude species; in the north of its range, it grows widely at 1,500 to 2,100 m (4,900 to 6,900 ft) altitude, and at 1,800 to 2,900 m (5,900 to 9,500 ft) in the south of its range.
