Tallest trees
The heights of the tallest trees in the world have been the subject of considerable dispute and much exaggeration. Modern verified measurement with
laser rangefinders combined with tape drop measurements made by tree climbers, carried out by the
U.S. Eastern Native Tree Society has shown that some older measuring methods and measurements are often unreliable, sometimes producing exaggerations of 5% to 15% above the real height. Historical claims of trees of 130 m (427 ft), and even 150 m (492 ft), are now largely disregarded as unreliable, and attributed to human error. Historical records of fallen trees measured prostrate on the ground are considered to be far more reliable. The following are now accepted as the top five tallest reliably measured species:
- Coast Redwood (Sequoia sempervirens): 115.56 m (379.1 ft), Redwood National Park, California, United States[10]
- Australian Mountain-ash (Eucalyptus regnans): 99.6 m (326.8 ft), south of Hobart, Tasmania, Australia[11]
- Coast Douglas-fir (Pseudotsuga menziesii): 99.4 m (326.1 ft), Brummit Creek, Coos County, Oregon, United States[12]
