The wood of slash pine is known for its unusually high strength, especially for a pine. ... (9,940 lb/in 2), but because its average density is less than half that of ...
Map of wood-filled areas in the United States, circa 2000 [1]. In the United States, the forest cover by state and territory is estimated from tree-attributes using the basic statistics reported by the Forest Inventory and Analysis (FIA) program of the Forest Service. [2]
[10] [13] The pine has also been used as a source of rosin and turpentine. The wood is pale brown to red-brown, and used for general construction work. It has a dry density around 470 kg/m 3 (varying with growth conditions), an open porosity of 60%, a fibre saturation point of 0.25 kg/kg, and a saturation moisture content of 1.60 kg/kg. [13]
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).
It is the most extensively used wood in New Zealand. [citation needed] Use of pine in construction did not become widespread until forced by wartime shortages. It had been used in Southland from about 1920, [34] but doubts were being expressed about it as late as 1945, [35] when at least one MP considered it only suitable for interior studding ...
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.
A pine is any conifer tree or shrub in the genus Pinus (/ ˈ p aɪ n ə s /) [2] of the family Pinaceae. Pinus is the sole genus in the subfamily Pinoideae.. World Flora Online accepts 134 species-rank taxa (119 species and 15 nothospecies) of pines as current, with additional synonyms, [3] and Plants of the World Online 126 species-rank taxa (113 species and 13 nothospecies), [4] making it ...
The bristlecone pine's root system is mostly composed of highly branched, shallow roots, while a few large, branching roots provide structural support. The bristlecone pine is extremely drought tolerant due to its branched shallow root system, its waxy needles, and thick needle cuticles that aid in water retention. [8] Gnarled bristlecone pine wood
