List of superlative trees

From Wikipedia, the free encyclopedia

The coniferous Coast redwood (Sequoia sempervirens) is the tallest tree species on earth.

The world's superlative trees can be ranked by any factor. Records have been kept for trees with superlative height, trunk diameter (girth), canopy coverage, airspace volume, wood volume, estimated mass, and age.

Tallest

[edit]
Main article: List of tallest trees

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:

Tallest historically

[edit]

Despite the tall heights attained by trees in the present, records exist of much greater heights in the past, before widespread logging took place. Some, if not most, of these records are likely greatly exaggerated, but some have been reportedly measured with semi-reliable instruments when cut down and on the ground. Some of the heights recorded in this way exceed the maximum possible height of a tree as calculated by theorists,[24] lending some limited credibility to speculation that some superlative trees are able to 'reverse' transpiration streams and absorb water through needles in foggy environments. All three of the tallest tree species continue to be Coast redwoods, Douglas-fir and Giant mountain ash.

Stoutest

[edit]
Árbol del Tule

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".[40]
Trunk of Te Matua Ngahere

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.[41][42] Breast height is defined differently in different situations, with most forestry measurements taking girth at 1.3 m above ground,[42] while those who measure ornamental trees usually measure at 1.5 m above ground;[41] 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,[41][42] but in North America a point is usually used which is the average of the highest point and the lowest point the tree trunk appears to contact the soil.[43] 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.[40] 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%[44]), 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.[59] 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]

Largest

[edit]
The General Sherman, a California giant sequoia, is the largest tree by volume
Further information: List of largest giant sequoias

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.

Oldest

[edit]
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)[92] 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 5,000 years[99][100]), Sugi (Cryptomeria japonica) (3,000 years or more[101]), 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. The Llangernyw Yew has been estimated as between 4000 and 5000 years in age by David Bellamy,[102] who also used radiocarbon dating to estimate an age of around 4000 years for the Tisbury Yew in Wiltshire,[103] while the Fortingall Yew with its former 16 to 17-meter girth is estimated at 5,000 years of age.[104][105] However, ageing yews is very difficult due to the loss of heartwood in very ancient trees, and one or two sources believe the trees to be far younger at around 1500–3000 years.

Lagarostrobos franklinii, known as Huon pine, is native to the wet southwestern corner of Tasmania, Australia. A stand of trees in excess of 10,500 years old was found in 1955 in western Tasmania on Mount Read.[106] Each of the trees in this stand is a genetically identical male that has reproduced vegetatively. Although no single tree in this stand is of that age, the stand itself as a single organism has existed that long.[107] Individual trees in the clonal patch have been listed as having ages of 2000[108][109] or even to 3000 years old.[110][111]

The olive tree also can live for centuries. Previously the oldest age verified by carbon dating was 900 years for a tree in the Gethsemane garden in Jerusalem.[112] In 2024 research was published showing that one of the trees in the Sisters Olive Trees of Noah to be 1,161 years old, plus or minus 131 years, by carbon dating.[113] Previously they had been reputed to be around 6,000 years old.[114]

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

[edit]

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.[115] El Drago Milenario, a tree of species Dracaena draco on Tenerife, Canary Islands, Spain, is reported to have 200-meter-long (660 ft) superficial roots.[116]

Thickest tree limbs

[edit]

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]

Giant Sequoia (Sequoiadendron giganteum) Sierra Nevada Mountains of California. The greatest thickness which has been reliably measured is 75 cm (2+1⁄2 ft) for one in Redwood Canyon, Kings Canyon National Park.[131] However it is asserted that the basal bark of the "General Sherman" Big Tree is in places up to 1.2 m (4 ft) in thickness.[132] 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 46 cm (18 in) thick.[133] 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 34 cm (13+1⁄2 in) in thickness.[134]
Cork Oak (Quercus suber) circum-Mediterranean distribution. One Cork Oak at the chapel of São Gonçalo 16 km (10 mi) south of Lisbon, Portugal had cork measuring 20 cm (8 in) deep.[135] This is the thickest bark among 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 18 cm (7 in) in depth plus an unknown depth of unfissured bark beneath. In 1996 the bark had grown about an additional 25 mm (1 in).
Monkey Puzzle Tree (Araucaria araucana) The Patagonian Andes of Chile and Argentina. Bark up to seven inches (18 centimeters) in thickness.[136][137]
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 18 cm (7 in) with again an unknown depth of unfissured bark below that.
Parana Pine (Araucaria angustifolia) Mostly in southernmost Brazil. Bark can be over 15 cm (6 in) thick.[138]
Renala (Adansonia grandidieri) Madagascar. Bark is up to 15 cm (6 in) thick.[139] 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 15 cm (6 in) in thickness.[140]
Plains Cottonwood (Populus deltoides ssp. monilifera) North American Plains. "Almost six inches (15 centimeters) thick"[141]
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+3⁄4 in (120 mm) deep. This is the thickest bark among Monocots.

Guyana Chestnut, or Provision Tree (Pachira aquatica) Central America, northern South America and the West Indies. Up to 66 cm (26 in) if the 33 cm (13 in) yellow petals are held outright.[142] The red tipped, yellow stamens[143] are united into a column in the lower third, divided into five or more sub-groups in the middle third, and into as many as 250 individual stamens in the upper third. According to Perry, P. aquatica petals can reach 14 inches (35 centimeters) in length.[144][145] The tree gets about 65 feet (20 meters) in height.[146]
Cacao Sauvage (Pachira insignis) Along brackish estuaries of South America and the Lesser Antilles. Its 33–36 cm (13–14 in) pink or red petals are 66–71 cm (26–28 in) wide if held horizontally.[147][148] The white stamens of P. insigna, arranged in the same manner as P. aquatica, can number as many as one thousand. This tree may grow up to 20 m (70 ft) in height in exceptional cases.[149]
Big Leaf Magnolia (Magnolia macrophylla) The deep southern United States, especially Alabama and Mississippi, but excluding Florida. The largest on record was 55 cm (21+1⁄2 in) in width.[150] Magnolia macrophylla has the largest flowers of any temperate (non-tropical) plant. This, like all Magnolias, is 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 51 cm (20 in) long and up to 20 cm (8 in) wide at the mouth.[151][152] At 5 m (16 ft) height, this is the smallest tree in this table. The pollinator is unknown,[153] but would seem to require a very long tongue or beak. The horticultural variety "Supernova" can be up to 24 in (61 cm) in length. B. versicolor is now believed to be extinct in the wild, but fortunately is widely cultivated.
Cloudforest Magnolia (Magnolia dealbata) The humid regions of Mexico. Up to 41 cm (16 in) in diameter.[154] Considered by some taxonomists to be a subspecies of M. macrophylla. One credible source states that M. dealbata can have flowers up to 50 cm (19+1⁄2 in) in width.[155]
Goniothalamus grandiflorus Annonaceae Solomon Islands Each of the three red petals up to seven inches (17 centimeters) in length,[156] for a potential width of fourteen inches (34 cm) Tree is cauliflorous (flowers borne directly on trunk, or major limbs). Each flower produces a multiple fruit, where each carpel develops as a separate berry and together forming a cluster resembling a cluster of large grapes.
Mandacaru (Cereus jamacaru) Cactaceae The Caatinga region of N.E.ern Brazil. Also naturalized to South Africa. Up to 30 cm (12 in) long by up to 20 cm (8 in) wide.[157][158] One of the largest tree-cacti at up to 18 m (59 ft) in height, 10 m (33 ft) crown spread and up to 102 cm (40 in) trunk thickness.[157] It can bear spines up to 19 cm (7+1⁄2 in) long.[citation needed] By reason of its succulence, these may be the most massive (heaviest) of all tree flowers.[citation needed]
The Paloeloe (Phenakospermum guianense) (Strelitziaceae) Amazon Rainforest. Each cicinnus contains up to 25 individual flowers, each up to eleven inches (28 centimeters) in length.[159]
Calabash Nutmeg (Monodora myristica) (Annonaceae) Native to tropical Africa. Ornate, pendant, multicolor flower up to 25 cm (10 in) in width. Usually found in sets of three flowers.[160] The name comes from the 15 cm (6 in) calabash-like fruit filled with fragrant seeds.
Ceiba schottii (Bombacaceae) Southern Mexico and Guatemala Up to 10.5 in (26 cm) wide by 7.5 in (19 cm) long.[161]
Gigasiphon humboldtianum (Caesalpinaceae) Madagascar, with very similar G. macrosiphon in coastal Kenya and Tanzania. Up to ten inches (25 centimeters) in length the hypanthium or floral tube surrounding the pistel-stipe or gynophore; both being the longest known for any plant.[162] The five petals( upper, central one yellow, the side ones white) are each five inches (13 centimeters) long and 2.5 inches (6.5 centimeters) wide.[163] for a total width of ten inches (25 centimeters| Many botanists consider G. humboldtianum and G. macrosiphon to be conspecific.
The Za or Boji (Adansonia za) Bombacaceae Widespread in Madagascar. Five mostly yellow petals, each up to 9.5 inches (24 centimeters) long by 0.6-inch (1.5 cm) wide, and reflexed.[164] Flower 9 to 10 inches (23 to 25 cm) wide with long stamens bringing the length to nine inches (23 centimeters). Largest of the Baobab flowers.
Hibiscus waimeae Malvaceae Endemic to the island of Kauai, in Hawai'i. Each of the five white petals is up to 5.5 inches (thirteen cm) in length for a potential diameter of eleven inches (26 centimeters) The central staminal column is up to six inches (fifteen cm) in length.[165]
Spotted Randia (Rothmannia longiflora) (Rubiaceae). Native to tropical Africa. Has trumpet-shaped Purple and white flowers up to ten inches (25 cm) long[166] by about five inches (12 cm) across the mouth.[167]
The Elephant Apple (Dillenia indica) (Dilleniaceae) Native to India, Burma, Southeast Asia and the East Indies. The 20 cm (8 in) wide flower consists of five large 50–65 mm (2–2+1⁄2 in) roundish, fleshy white petals, two concentric circles of several hundred stamens surrounding a circle of up to twenty stigmas.[168][169] Forms a fruit up to 18 cm (7 in) in diameter.[170] A second species, D. megalantha of the Philippines, also produces 8-inch (20 centimeter) wide flowers.[171]
