Douglas-fir is one of the world's best timber-producing species and yields more timber than any other species in North America, making the forestlands of western Oregon, Washington, and British Columbia the most productive on the continent. In 2011, Douglas-fir represented 34.2% of US lumber exports, to a total of 1.053 billion board-feet.
Anecdotal reports do exist of other Douglas fir and mountain ash trees reaching 400 to 500 feet (122 to 152 m), such as the 435 ft (133 m) "Ferguson Tree," a Eucalyptus regnans of the Watt's river, Australia in 1872, or the 415 ft (126 m) Lynn Valley Tree, a Douglas fir felled in 1902. They are often dismissed as unreliable; however, some are ...
Pseudotsuga menziesii (Douglas fir proper) is widespread in western North America and is an important source of timber. The number of species has long been debated, but two in western North America and two to four in eastern Asia are commonly acknowledged.
Big Lonely Doug is a large Coast Douglas-fir (Pseudotsuga menziesii) tree located in the Gordon River Valley, 10km north of Port Renfrew on Vancouver Island, British Columbia, Canada. It is the second largest Douglas-fir tree in Canada after the Red Creek Fir in nearby San Juan Valley .
Pseudotsuga macrocarpa, commonly called the bigcone spruce or bigcone Douglas-fir, is an evergreen conifer native to the mountains of southern California. It is notable for having the largest (by far) cones in the genus Pseudotsuga , hence the name.
Pseudotsuga menziesii var. glauca, or Rocky Mountain Douglas-fir, is an evergreen conifer native to the interior mountainous regions of western North America, from central British Columbia and southwest Alberta in Canada southward through the United States to the far north of Mexico. [2]
Coast Douglas-fir is the fourth tallest conifer and fifth tallest of all trees in the world (after sitka spruce).Currently, coast Douglas-fir trees 60–75 metres (197–246 ft) or more in height and 1.5–2 metres (4.9–6.6 ft) in diameter are common in old growth stands, [4] and maximum heights of 100–120 metres (330–390 ft) and diameters up to 4.5–5.5 metres (15–18 ft) have been ...
The timber is used for construction, bridge building, furniture, and wood fiber. [2] [4] Pseudotsuga sinensis var. wilsoniana, Taiwan Douglas-fir, is sometimes treated as its own species, Pseudotsuga wilsoniana. This variety is geographically isolated (being restricted to Taiwan) but is not markedly distinct morphologically from var. sinensis ...
