Methuselah is a 4,856-year-old [1] Great Basin bristlecone pine (Pinus longaeva) tree growing high in the White Mountains of Inyo County in eastern California. [2] [3] It is recognized as the non-clonal tree with the greatest confirmed age in the world. [4] Its old age is a result of harsh weather and a lack of nutrients, which slow down the decaying process. [5] The tree's name refers to the biblical patriarch Methuselah, who is said to have reached 969 years of age before his death, thus becoming synonymous with longevity or old age in many European languages including English. [6] [7]
Methuselah is located between 2,900 and 3,000 m (9,500 and 9,800 ft) above sea level in the "Methuselah Grove" in the Ancient Bristlecone Pine Forest within the Inyo National Forest. The United States Forest Service does not disclose its exact location, although the tree's location is now widely known and available on the internet following a high-profile leak in 2021 after photos of the exact tree were found in a National Geographic article as well as its appearance in a documentary. [8] [9] [10] [11] [12] The tree's location was withheld for years out of fear the tree would be damaged.
The claim that Methuselah is the oldest known tree is controversial.
Methuselah was 4,789 years old when sampled in 1957 [13] by Edmund Schulman and Tom Harlan, [1] with an estimated germination date of 2833 BC.
Dendrochronologist Matthew Salzer of the University of Arizona has been unable to reproduce Schulman's age estimate, due to a missing core. Salzer's estimate is approximately 4,667 years old. [14]
After the Llangernyw Yew was assessed by David Bellamy as 4,000 to 5,000 years old [15] "using all available data", and the Fortingall Yew, with its former 16 to 17-meter girth, [16] assessed as 5,000 years old, Methuselah may have lost claim to the title of world's oldest non-cloning tree. [17] Though newer studies indicate a younger age between 2,000-3,000 years old. [18] The Rocky Mountain Tree-Ring Research Old List does not list these trees. [19]
Another bristlecone specimen, WPN-114, nicknamed "Prometheus", was more than 4,844 years old when cut down in 1964, with an estimated germination date of 2880 BC. A dendrochronology, based on these trees and other bristlecone pine samples, extends back to about 9000 BC, albeit with a single gap of about 500 years. [20] [3]
An older bristlecone pine was reportedly discovered by Tom Harlan in 2009, based on a sample core collected in 1957. According to Harlan, the tree was 5,062 years old and still living in 2010. Neither the tree nor the sample core could be located after Harlan's death in 2013. [4]
Although Methuselah is the oldest known non-clonal organism for which a reliable age has been established, the Alerce Milenario in Chile (5,484 years old), [21] [22] Llangernyw Yew in Wales (4,000 – 5,000 years old) and especially the Fortingall Yew in Scotland (3,000 – 9,000 years old) have some age estimates exceeding that of Methuselah. [23] [24] [25] [26] [27]
Other, longer-lived organisms are clonal colonies, such as a quaking aspen (Populus tremuloides) colony named "Pando" in the Fish Lake National Forest in south-central Utah that has been estimated to be 80,000 years old, although precise estimates of clonal organisms such as this aspen colony are impossible with current technologies, and other scientific attempts to age Pando have estimated it may be much younger; the 11,700-year-old creosote bush (Larrea tridentata) colony, named "King Clone", in the Mojave Desert near the Lucerne Valley in California; and the 9,500-year-old Norway spruce (Picea abies) colony named "Old Tjikko" in Sweden. [28] [29] [30]
Methuselah was a biblical patriarch and a figure in Judaism, Christianity, and Islam. He is claimed to have lived the longest life, dying at 969 years of age. According to the Book of Genesis, Methuselah was the son of Enoch, the father of Lamech, and the grandfather of Noah. Elsewhere in the Bible, Methuselah is mentioned in genealogies in 1 Chronicles and the Gospel of Luke.
Larrea tridentata, called creosote bush and greasewood as a plant, chaparral as a medicinal herb, and gobernadora in Mexico, due to its ability to secure more water by inhibiting the growth of nearby plants. In Sonora, it is more commonly called hediondilla; Spanish hediondo = "smelly".
The term bristlecone pine covers three species of pine tree. All three species are long-lived and highly resilient to harsh weather and bad soils. One of the three species, Pinus longaeva, is among the longest-lived life forms on Earth. The oldest of this species is more than 4,800 years old, making it the oldest known individual of any species. Many scientists are curious as to why this tree is able to live so long. In one study, they discovered that Pinus longaeva has higher levels of telomerase activity, which further slows or prevents the attrition rate of telomeres. This potentially contributes to the extended life of the bristlecone pine.
Pinus longaeva is a long-living species of bristlecone pine tree found in the higher mountains of California, Nevada, and Utah. Methuselah is a bristlecone pine that is 4,856 years old and has been credited as the oldest known living non-clonal organism on Earth. To protect it, the exact location of this tree is kept secret. In 1987, the bristlecone pine was designated one of Nevada's state trees.
A clonal colony or genet is a group of genetically identical individuals, such as plants, fungi, or bacteria, that have grown in a given location, all originating vegetatively, not sexually, from a single ancestor. In plants, an individual in such a population is referred to as a ramet. In fungi, "individuals" typically refers to the visible fruiting bodies or mushrooms that develop from a common mycelium which, although spread over a large area, is otherwise hidden in the soil. Clonal colonies are common in many plant species. Although many plants reproduce sexually through the production of seed, reproduction occurs by underground stolons or rhizomes in some plants. Above ground, these plants most often appear to be distinct individuals, but underground they remain interconnected and are all clones of the same plant. However, it is not always easy to recognize a clonal colony especially if it spreads underground and is also sexually reproducing.
Pinus aristata, the Rocky Mountain bristlecone pine or Colorado bristlecone pine is a long-lived species of bristlecone pine tree native to the United States. It is found in the Rocky Mountains in Colorado and northern New Mexico, with an isolated population in the San Francisco Peaks of Arizona. It is found at very high altitudes, from 2,100 to 4,000 meters in cold, dry subalpine climate conditions, often at the tree line, although it also forms extensive closed-canopy stands at somewhat lower elevations.
King Clone is thought to be the oldest creosote bush ring in the Mojave Desert. The ring is estimated to be 11,700 years old, making it one of the oldest living organisms on Earth. This single clonal colony plant of Larrea tridentata reaches up to 67 feet in diameter, with an average diameter of 45 feet (14 m).
Inyo National Forest is a United States National Forest covering parts of the eastern Sierra Nevada of California and the White Mountains of California and Nevada. The forest hosts several superlatives, including Mount Whitney, the highest point in the contiguous United States; Boundary Peak, the highest point in Nevada; and the Ancient Bristlecone Pine Forest, which protects the oldest living trees in the world. The forest, encompassing much of the Owens Valley, was established by Theodore Roosevelt as a way of sectioning off land to accommodate the Los Angeles Aqueduct project in 1907, making the Inyo National Forest one of the least wooded forests in the U.S. National Forest system.
The Ancient Bristlecone Pine Forest is a protected area high in the White Mountains in Inyo County in eastern California.
Prometheus was the oldest known non-clonal organism, a Great Basin bristlecone pine tree growing near the tree line on Wheeler Peak in eastern Nevada, United States. The tree, which was at least 4,862 years old and possibly more than 5,000, was cut down in 1964 by a graduate student and United States Forest Service personnel for research purposes. Those involved did not know of its world-record age before the cutting, and the circumstances and decision-making process remain controversial.
The Fortingall Yew is an ancient European yew in the churchyard of the village of Fortingall in Perthshire, Scotland. Considered one of the oldest trees in Britain, modern estimates place its age at an average of 5,000 years.
Donald Rusk Currey was an American professor of geography. While known in academia for his extensive research and exploration of relics of the ancient Lake Bonneville in the eastern Great Basin, he was best known to the public for his controversial felling of Prometheus, the oldest living non-clonal organism known at the time, while a graduate student in 1964.
The Madrean region is a floristic region within the Holarctic kingdom in North America, as delineated by Armen Takhtajan and Robert F. Thorne. It occupies arid or semiarid areas in the southwestern United States and northwestern Mexico and is bordered by the Rocky Mountain floristic region and North American Atlantic region of the Holarctic kingdom in the north and in the east, Caribbean region of the Neotropical kingdom in the south.
Negligible senescence is a term coined by biogerontologist Caleb Finch to denote organisms that do not exhibit evidence of biological aging (senescence), such as measurable reductions in their reproductive capability, measurable functional decline, or rising death rates with age. There are many species where scientists have seen no increase in mortality after maturity. This may mean that the lifespan of the organism is so long that researchers' subjects have not yet lived up to the time when a measure of the species' longevity can be made. Turtles, for example, were once thought to lack senescence, but more extensive observations have found evidence of decreasing fitness with age.
The Llangernyw Yew ( ) is an ancient yew in the village of Llangernyw, Conwy, Wales. The tree is fragmented and its core part has been lost, leaving several enormous offshoots. The girth of the tree at the ground level is 10.75 m (35.3 ft).
