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.
By far the best-known is the very widespread and abundant North American species Pseudotsuga menziesii, a taxonomically complex species [14] divided into two major varieties (treated as distinct species or subspecies by some botanists): coast Douglas-fir or "green Douglas-fir", on the Pacific coast; and Rocky Mountain Douglas-fir or "interior ...
Coast Douglas-fir is the second-tallest conifer in the world (after coast redwood), and the third-tallest of all trees, (after Eucalyptus regnans).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. ...
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]
Some hybrids of Pseudotsuga macrocarpa (Bigcone Douglas-fir) × Pseudotsuga menziesii (Coast Douglas-fir) show promise for planting on drier restoration sites within the P. menziesii−Douglas-fir natural range. These hybrids produce wood of comparable quality to that of Douglas-fir and have the drought tolerance of bigcone Douglas-fir.
The Olympic rainforest of Washington supports dense stands of western hemlock, western red cedar, Sitka spruce, and Pacific silver and grand firs. Douglas fir is concentrated in Washington and Oregon. Alaska's predominate species is the western hemlock and Sitka spruce.
