Ponderosa Pine – Pinus ponderosa

Pinus ponderosa, commonly known as the ponderosa pine, bull pine, blackjack pine,or western yellow pine, is a very large pine tree species of variable habitat native to the western United States and Canada. The tree is a major source of timber, ponderosa pine forests are also important as wildlife habitat, for recreational use, and for esthetic values.
Ponderosa pine is a large tree with an irregular crown, eventually developing a flat top or short conical crown. Ponderosa pine self-prunes well and develops a clear bole. Trees grow to 72 feet with 250 inch diameter trunks. Bark is yellow- to red-brown, deeply irregularly furrowed, and cross-checked into broadly rectangular, scaly plates. Younger trees have blackish-brown bark, referred to as “blackjacks” by early loggers. Ponderosa pine’s five subspecies, as classified by some botanists, can be identified by their characteristically bright, green needles. Evergreen needles, 5 to 10 inches long, with three (sometimes 2) tough, yellow-green needles per fascicle. When crushed, needles have a turpentine odor sometimes reminiscent of citrus. Male cones are oval to round, yellow or red. Female cones mature in 2 years, shedding seeds soon thereafter, leaving rosettes of scales on branchlets. They are borne solitary or rarely in pairs, spreading to reflexed, oval to round before opening, broadly ovoal when open. Mature cones are reddish brown, with scales in steep spirals of 5-7 per row as viewed from side.
