This is converted to and cited as dbh ( diameter at breast height) in tree and forestry literature. Īs a general standard, tree girth is taken at "breast height". This tree has died, the likely cause being more frequent heatwaves and reduced rainfall. Note: all the references to this species are historical accounts - there is no currently known living klinki of this height. Note: Progressively lost height until falling in a storm. Largest known single-stemmed tree to have ever existed Note: Cut down in 1902 and measured on the ground Note: Cut down in 1872, and measured on the ground. List of tallest historically known non-surviving or lost trees All three of the tallest tree species continue to be Coast redwoods, Douglas fir and Giant mountain ash. Some of the heights recorded in this way exceed the maximum possible height of a tree as calculated by theorists, lending some limited credibility to speculation that some superlative trees are able to 'reverse' transpiration streams and absorb water through needles in foggy environments. Some, if not most, of these records are without a doubt greatly exaggerated, but some have been reportedly measured with semi-reliable instruments when cut down and on the ground. Messmate stringybark ( Eucalyptus obliqua)ĭespite the high heights attained by trees nowadays, records exist of much greater heights in the past, before widespread logging took place.
Neeminah Loggerale Meena, or Mother and Daughter This entry needs clarification: The photo provided of the tree in the reference shows a tree that is perhaps 50m tall - definitely not 94m Giant sequoia ( Sequoiadendron giganteum) Prairie Creek Redwoods State Park, California The correct height of the tree is 98.53m - that is the midpoint between the top of the bole at 96.26 and the low point of the buttress at 100.8 The original quoted figure of 100.8m was from the top leaves to the bottom of the buttresses on the low side of ground. Yarlung Zangbo National Nature Reserve, TibetĬoast Douglas-fir ( Pseudotsuga menziesii var. This table shows only currently standing specimens: The following are the tallest reliably measured specimens from the top 10 species. Historical claims of trees growing to 130 m (430 ft), and even 150 m (490 ft), are now largely disregarded as unreliable, and attributed to human error. Modern verified measurements with laser rangefinders or with tape drop measurements made by tree climbers (such as those carried out by canopy researchers), have shown that some older tree height measurement methods are often unreliable, sometimes producing exaggerations of 5% to 15% or more above the real height. The heights of the tallest trees in the world have been the subject of considerable dispute and much exaggeration. The coniferous Coast redwood ( Sequoia sempervirens) is the tallest tree species on earth.
