Douglas-fir is a medium-sized to extremely large evergreen tree, 20–100 metres (70–330 feet) tall (although only coast Douglas-firs, reach heights near 100 m) [10] and commonly reach 2.4 m (8 ft) in diameter, [11] although trees with diameters of almost 5 m (16 ft) exist. [12]
The difficulty of getting water so far up into the sky is what ultimately constrains growth. [45] Other researchers have developed models of maximum height for Coast Douglas-fir ( Pseudotsuga menziesii var. menziesii ) trees that yield similar estimates of 109–138 meters (357–452 feet), [ 46 ] a range that includes the height of the tallest ...
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 ...
Cragside House Fir: Douglas Fir (Pseudotsuga menziesii) 61.5 202 Cragside House, Northumberland: This is the tallest tree in England and has a girth exceeding 5 meters, which has been rapidly increasing in size. It was reported that the tree lost its original top in 2016. [30] Center Parcs Sequoia: Giant Sequoia (Sequoiadendron giganteum) 58 190
Coast Douglas-fir seed cone, from a tree grown from seed collected by David Douglas 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 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). [2] The Doerner Fir was previously measured in 1991 at 329 feet (100.3 m) tall but had lost ...
LiDAR-derived height measurements were more accurate for ponderosa pine (-0.43 i: 0.13 m) than for Douglas-fir (-1.05 i: 0.41 m) at the narrow beam setting. Tree heights acquired using conventional field techniques (-0.27 2 0.27 m) were more accurate than those obtained using LiDAR (-0.73 i: 0.43 m for narrow beam setting).
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. ...
