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.

Tallest

Main article: List of tallest trees
The coniferous Coast redwood (Sequoia sempervirens) is the tallest tree species on earth.

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.[1] 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 following are the tallest reliably measured specimens from the top 10 species. This table shows only currently standing specimens:

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.

All 12 of the world's largest trees are Giant sequoias. Grogan's Fault, the largest living Coast redwood, would rank as the 13th largest living tree. Tāne Mahuta, the largest living tree outside of California, would rank within the top 100 largest living trees.

Stoutest

Trunk of Te Matua Ngahere

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".[31]

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.[32][33] Breast height is defined differently in different situations, with most forestry measurements taking girth at 1.3 m above ground,[33] while those who measure ornamental trees usually measure at 1.5 m above ground;[32] 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,[32][33] 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.[34] 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.[31] 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%[35]), 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.[49] 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.[citation needed]

Oldest

Great Basin bristlecone pine (Pinus longaeva) is the longest living tree species on Earth.
Main article: List of oldest trees

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)[73] 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:

Other species suspected of reaching exceptional age include European Yew (Taxus baccata) (probably over 2,000 years[78][79]), Sugi (Cryptomeria japonica) (3,000 years or more[80]), 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.[81]

The olive tree also can live for centuries. The oldest verified age is 900 years[82] 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.[83]

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.

Deepest and longest tree roots

A wild fig tree growing in Echo Caves near Ohrigstad, South Africa has roots going 120 m (400 ft) deep, giving it the deepest roots known of any tree.[84] El Drago Milenario, a tree of species Dracaena draco on Tenerife, Canary Islands, Spain, is reported to have 200-metre-long (660 ft) aerial roots.[85]

Thickest tree limbs

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]

Thickest tree bark

List of trees by thickest bark
Species Native range Greatest thickness or depth Comments
Giant Sequoia (Sequoiadendron giganteum) Sierra Nevada Mountains of California. The greatest thickness which has been reliably measured is 2.5 feet (76.2 cm) for one in Redwood Canyon, Kings Canyon National Park.[101] However it is asserted that the basal bark of the "General Sherman" Big Tree is in places up to four feet (121.9 centimeters) in thickness.[102] This could be determined non-invasively with sonograph equipment.
Coast Redwood (Sequoia sempervirens) Coastal Northern and Central California and extreme southern Oregon. The "Mill Creek Giant" near the Mill Creek bridge in Redwood National Park, Crescent City, California has bark eighteen inches (45.7 centimeters) thick.[103] Coast Redwood bark is often deeply fissured, making it easy to measure most of the depth of the bark even on live trees.
Douglas Fir (Pseudotsuga menziesii) Northwestern North America. A tree felled in North Vancouver, British Columbia in 1902 had bark 13.5 inches (34.3 centimeters) in thickness.[104]
Cork Oak (Quercus suber) circum-Mediterranean distribution. One Cork Oak at the chapel of Sao Goncalo ten miles (16 kilometers) south of Lisbon, Portugal had cork measuring eight inches (20 cm) deep.[105] This is the thickest bark amongst Dicots. One Cork Oak at the Mission-Basilica San Carlos de Borromeo del Rio Carmelo, Carmel-by-the-Sea, California had bark in 1971 with fissures seven inches (17.8 cm) in depth plus an unknown depth of unfissured bark beneath. In 1996 the bark had grown about one additional inch (2.54 cm).
Bangalay (Eucalyptus botryoides) Victoria and New South Wales, Australia. In 1973, one Bangalay in Alameda Park, Santa Barbara, California had bark fissured to a depth of seven inches (17.8 cm) with again an unknown depth of unfissured bark below that.
Parana Pine (Araucaria angustifolia) Mostly in southernmost Brazil. Bark can be over six inches ("more than 15 centimeters") thick.[106]
Renala (Adansonia grandidieri) Madagascar. Bark is up to six inches (fifteen centimeters) thick.[107] This is the species with the colossal columnar trunks.
Valley Oak (Quercus lobata) Central Valley of California southward to the San Gabriel Valley. This bark also up to six inches (i5 cm) in thickness.[108]
Nolina longifolia Mexico One plant at the Huntington Library, Galleries and Botanical Gardens, San Marino, California in 1996 had bark with fissures up to 4.75 inches ( 12.1 centimeters) deep. This is the thickest bark amongst Monocots.

Guyana Chestnut, or Provision Tree (Pachira aquatica) Central America, northern South America and the West Indies. Up to 26 inches (66 cm) if the thirteen inch (33 cm) pale yellow petals are held outright.[109] The stamens are united into a column in the lower third, divided into five sub-groups in the middle third, and into several hundred individual stamens in the upper third.
Cacao Sauvage (Pachira insigna) Along brackish estuaries of South America and the Lesser Antilles. Its 13-to-14-inch (33 to 36 cm) pink petals are 26 to 28 inches (66 to 71 cm) wide if held horizontally.[110][111] This is a much taller tree than P. aquatica, up to one hundred feet (30 meters) in height.
Big Leaf Magnolia, or Big Bloom (Magnolia macrophylla) The deep southern United States, especially Alabama and Mississippi, but excluding Florida. The largest on record was 21.5 inches (54.6 cm) in width,[112] while another found and photographed by Adele Sayle was twenty inches (51 cm) wide.[113] Magnolias are pollinated by flower beetles.
Giant White Angel's Trumpet (Brugmansia versicolor) Northern Guayaquil River Basin of Ecuador. Pendant white or cream trumpet-like flowers up to twenty inches (51 cm) long and up to eight inches (20 cm) wide at the mouth.[114][115] At 16.4 feet (five meters) height, this is the smallest tree in this table. The pollinator is unknown,[116] but would seem to require a very long tongue or beak.
Magnolia dealbata The humid regions of Mexico. Up to 16 inches (41 cm) in diameter.[117] Considered by some taxonomists to be a subspecies of M. macrophylla. One credible source states that M. dealbata can have flowers up to 19.5 inches (50 centimeters) in width.[118]
Mandacaru (Cereus jamacaru) The Caatinga region of N.E.ern Brazil. Also naturalized to South Africa. Up to 12 inches (30 cm) long by up to 8 inches (20 cm) wide.[119] One of the largest tree-cacti at up to 59 feet (18 meters) in height, 33 feet (ten meters) crown spread and up to 39 inch (one meter) thick trunk.[119] It can bear spines up to 7.5 inches (19 cm) long.[citation needed] By reason of its succulence, these may be the most massive (heaviest) of all tree flowers.[citation needed]
Calabash Nutmeg (Monodora myristica) Native to tropical Africa. Ornate, multicolor flower up to 10 inches (25 cm) in width.[120] The name comes from the six inch (15 cm) calabash-like fruit filled with fragrant seeds.
The Elephant Apple (Dillenia indica) Native to India, Burma, Southeast Asia and the East Indies. The eight inch (20 cm) wide flower consists of five large 2-to-2+1⁄2-inch (5.1 to 6.4 cm) roundish, fleshy white petals, two concentric circles of several hundred stamens surrounding a circle of up to twenty stigmas.[121][122] Forms a fruit up to 6 in. (15 cm) in diameter.
