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 ...
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 reliably-measured historical (dead) specimen, a 126-meter tree.
The President Tree (Sequoiadendron giganteum) [3] was measured in 2012 to have a trunk volume of 54,000 cubic feet (1,500 m 3) of wood and a branch volume of 9,000 cubic feet (250 m 3) of wood in the branches. In this giant tree the branch volume was only 16.7% that of the trunk volume.
This enables the shapes of different trees of different sizes to be compared. The final step is to plot these results as a ternary graph to better compare the results. As an example, the measurement data for 140 live oaks measured as part of the NTS Live Oak Project [39] were graphically plotted using this process. Tree shape diagram for live oak
Douglas-fir seeds are an extremely important food source for small mammals such as moles, shrews, and chipmunks, which consume an estimated 65% of each annual seed crop. The Douglas squirrel harvests and hoards great quantities of Douglas-fir cones, and also consumes mature pollen cones, the inner bark, terminal shoots, and developing young ...
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).
The Queets Fir is a superlative Douglas fir about 2.5 miles from the Queets River Trail trailhead, [1] [2] on Coal Creek, a tributary of Queets River in the Olympic National Park in Washington State. It was known for fifty years, beginning in 1945, as the largest known fir by volume, and is still largest known in diameter. [ 3 ]
