Pinus ponderosa, commonly known as the ponderosa pine, [3] bull pine, blackjack pine, [4] western yellow-pine, [5] or filipinus pine, [6] is a very large pine tree species of variable habitat native to mountainous regions of western North America. It is the most widely distributed pine species in North America.
Ponderosa pine forest is a plant association and plant community dominated by ponderosa pine and found in western North America. It is found from the British Columbia to Durango, Mexico . [ 1 ] In the south and east, ponderosa pine forest is the climax forest , while in the more northern part of its range, it can transition to Douglas-fir or ...
The pure stands of Rocky Mountain ponderosa pine forest receive about 15–20 inches (380–510 mm) of annual precipitation. [7] In the northern Rockies, about 40-50% falls in April through September, while in the southern Rockies, about 66-75% falls during these months. [7]
The ponderosa pine forests were close to the developing population centers at the forest-prairie edge. The scale of the loss of ponderosa pine habitat is demonstrated best in several hundred paired photographs from the early 20th century and 1980s. However, nearly all the paired photographs also reveal that the most important feature of the ...
The Willamette Valley ponderosa variant only grows on the valley floor, unlike the Douglas-fir, which grows on hillsides, and the wood is softer and easier to mill than the native hardwoods. [1] Because of this, when early settlers used wood from the trees to build homes and cleared land for agriculture, the population was "decimated". [ 1 ]
Jeffrey pine wood and ponderosa pine wood are sold together as yellow pine. [6] Both kinds of wood are hard (with a Janka hardness of 550 lbf (2,400 N)), but the western yellow pine wood is less dense than southern yellow pine wood (28 lb/cu ft (0.45 g/cm 3 ) versus 35 lb/cu ft (0.56 g/cm 3 ) for shortleaf pine).

The tree was 202 feet (62 m) tall [2] [3] with a diameter of 7 feet (210 cm), [4] and was one of the largest known Ponderosa pines in the world. [1] After stress by attacks from mountain pine beetles [ 4 ] its death in 2015 was confirmed the following year.
