List of superlative trees
The world's superlative trees can be ranked by any factor. Records have been kept for trees with superlative height, trunk diameter or girth, canopy coverage, airspace volume, wood volume, estimated mass, and age.
The heights of the tallest trees in the world have been the subject of considerable dispute and much exaggeration. 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. 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.

The largest trees are defined as having the highest wood volume in a single-stem. These trees are both tall and large in diameter and, in particular, hold a large diameter high up the trunk. Measurement is very complex, particularly if branch volume is to be included as well as the trunk volume, so measurements have only been made for a small number of trees, and generally only for the trunk. Few attempts have ever been made to include root or leaf volume.

The girth of a tree is usually much easier to measure than the height, as it is a simple matter of stretching a tape round the trunk, and pulling it taut to find the circumference. Despite this, UK tree author Alan Mitchell made the following comment about measurements of yew trees:
The aberrations of past measurements of yews are beyond belief. For example, the tree at Tisbury has a well-defined, clean, if irregular bole at least 1.5 m long. It has been found to have a girth that dilated and shrunk in the following way: 11.28 m (1834 Loudon), 9.3 m (1892 Lowe), 10.67 m (1903 Elwes and Henry), 9.0 m (1924 E. Swanton), 9.45 m (1959 Mitchell) ... Earlier measurements have therefore been omitted.— Alan Mitchell; in a handbook "Conifers in the British Isles".
As a general standard, tree girth is taken at "breast height". This is converted to and cited as dbh (diameter at breast height) in tree and forestry literature. Breast height is defined differently in different situations, with most forestry measurements taking girth at 1.3 m above ground, while those who measure ornamental trees usually measure at 1.5 m above ground; in most cases this makes little difference to the measured girth. On sloping ground, the "above ground" reference point is usually taken as the highest point on the ground touching the trunk, but in North America a point, that is the average of the highest point and the lowest point the tree trunk appears to contact the soil, is usually used. Some of the inflated old measurements may have been taken at ground level. Some past exaggerated measurements also result from measuring the complete next-to-bark measurement, pushing the tape in and out over every crevice and buttress. The measurements could also be influenced by deviation of the tape measure from a horizontal plane (which might seem called for if the trunk does not grow straight up), and the presence of features such as branches, spikes, etc.
Modern trends are to cite the tree's diameter rather than the circumference. The diameter of the tree is calculated by finding the mean diameter of the trunk, in most cases obtained by dividing the measured circumference by π; this assumes the trunk is mostly circular in cross-section (an oval or irregular cross-section would result in a mean diameter slightly greater than the assumed circle). Accurately measuring circumference or diameter is difficult in species with the large buttresses that are characteristic of many species of rainforest trees. Simple measurement of circumference of such trees can be misleading when the circumference includes much empty space between buttresses. See also Tree girth measurement
Baobabs (genus Adansonia) store large amounts of water in the very soft wood in their trunks. This leads to marked variation in their girth over the year (though not more than about 2.5%), reaching maximum at the end of the rainy season, and minimum at the end of the dry season.

Measurements become ambiguous when multiple trunks (whether from an individual tree or multiple trees) grow together. The Sacred Fig grows adventitious roots from its branches, which become new trunks when the root reaches the ground and thickens; a single sacred fig tree can have hundreds of such trunks. The multi-stemmed Hundred Horse Chestnut was known to have a circumference of 57.9 m (190 ft) when it was measured in 1780.
There are known more than 50 species of trees exceeding the diameter of 4.45 m or circumference of 14 m.
The trees with the broadest crowns have the widest spread of limbs from a single trunk.

The oldest trees are determined by growth rings, which can be seen if the tree is cut down, or in cores taken from the bark to the center of the tree. Accurate determination is only possible for trees that produce growth rings, generally those in seasonal climates. Trees in uniform non-seasonal tropical climates grow continuously and do not have distinct growth rings. It is also only possible for trees that are solid to the center. Many very old trees become hollow as the dead heartwood decays. For some of these species, age estimates have been made on the basis of extrapolating current growth rates, but the results are usually largely speculation. White (1998) proposes a method of estimating the age of large and veteran trees in the United Kingdom through the correlation of a tree's age with its diameter and growth character.
The verified oldest measured ages are:
|Species||Age||Tree name||Location||Notes and References|
|Great Basin bristlecone pine (Pinus longaeva)||5,067 years||Inyo County, California|||
|Alerce (Fitzroya cupressoides)||3,647 years||Gran Abuelo||Cordillera Pelada, Chile|||
|Giant sequoia (Sequoiadendron giganteum)||3,266 years||Sierra Nevada, California||Dead|
|Western juniper (Juniperus occidentalis)||2,675 years||Sierra Nevada, California||Dead|
|Rocky Mountain Bristlecone Pine (Pinus aristata)||2,460 years||central Colorado|||
|Sacred fig (Ficus religiosa)||2,302 years||Anuradhapura, Sri Lanka|||
|Coast Redwood (Sequoia sempervirens)||2,200 years||northern California||Dead|
Other species suspected of reaching exceptional age include European Yew (Taxus baccata) (probably over 2,000 years), Sugi (Cryptomeria japonica) (3,000 years or more), and Western Redcedar (Thuja plicata). The oldest known European Yew may be the Llangernyw Yew in the Churchyard of Llangernyw village in North Wales, or the Fortingall Yew in Perthshire, Scotland. These yews may be from 1,500 to 3,000 years old.
The olive tree also can live for centuries. The oldest verified age is 900 years at Gethsemane (Mount of Olives, as mentioned in the Bible), while several other olive trees are suspected of being 2,000 to 3,000 years old.
The pond cypress, Taxodium ascendens, has been known to live more than 1,000 years. One specimen in particular, named "The Senator", was estimated to be more than 3,400 years old at the time of its demise in early 2012.
Thickest Tree LimbEdit
This list is limited to horizontal or nearly horizontal limbs, in which the governing growth factor is phototropism. Vertical or near vertical limbs, in which the governing growth factor is negative geotropism, are called "reiterations" and are really divisions of the trunk, which by definition must be less than the trunk as a whole and therefore less remarkable. The thickest trunks have already been dealt with under "stoutest".[clarification needed]
