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 Douglas fir (Pseudotsuga menziesii) [4] is an evergreen conifer species in the pine family, Pinaceae. It is native to western North America and is also known as Douglas-fir , [ 5 ] Douglas spruce , [ 6 ] Oregon pine , [ 7 ] and Columbian pine . [ 8 ]
It occurs from 600 m altitude in the north of the range, up to 3,000 m, rarely 3,200 m, in the south. Further west towards the Pacific coast, it is replaced by the related coast Douglas-fir (Pseudotsuga menziesii var. menziesii), and to the south, it is replaced by Mexican Douglas-fir in high mountains as far south as Oaxaca.
Pseudotsuga menziesii var. menziesii has attained heights of 393 feet (120* m). That was the estimated height of the tallest conifer ever well-documented, the Mineral Tree ( Mineral, Washington ), measured in 1924 by Dr. Richard E. McArdle, [ 7 ] former chief of the U.S. Forest Service. [ 8 ]
The range is part of the Northern California coastal forests ecoregion. It is largely forested with climax-dominant trees including coast Douglas-fir (Pseudotsuga menziesii ssp. menziesii), oak (Quercus garryana and Q. kelloggii), and tanoak (Lithocarpus densiflorus), with pockets of Sugar Pine (Pinus lambertiana) found along steep slopes above the fogline.
One of the most prominent is the Coastal Douglas-fir (Pseudotsuga menziesii) forest, which includes Coast live oak, Tanoak, and California bay and reaches across the southern half of Inverness Ridge toward Bolinas Lagoon. Unlogged parts of this Douglas-fir forest contain trees over 300 years old and up to 6 feet (1.8 m) in diameter.
The Wasatch Range is traversed by just seven highways, along with several rugged mountain roads and unpaved trails. The most prominent are I-80 through Parley's Canyon east of Salt Lake City and I-84 through Weber Canyon southeast of Ogden. They meet near the ghost town of Echo on the eastern slopes of the range and continue northeast as I‑80.
The Doerner Fir, also known as the Brummitt Fir, is a former record-setting Coast Douglas-fir (Pseudotsuga menziesii var. menziesii) in Oregon, is one of the tallest known trees in the world which is not a redwood (Sequoioideae), at 325.8 feet (99.3 m).
