Methuselah (tree)

Methuselah is a -year-old Great Basin bristlecone pine (Pinus longaeva) tree growing high in the White Mountains of Inyo County in eastern California. It is recognized as the non-clonal tree with the greatest confirmed age in the world. The tree's name refers to the biblical patriarch Methuselah, who ostensibly lived to 969 years of age, thus becoming synonymous with longevity or old age in many European languages including English. Methuselah is located between 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. Methuselah was 4,789 years old when sampled in 1957 by Edmund Schulman and Tom Harlan, with an estimated germination date of 2833 BC. Since this tree ages back to this date, using tree rings, research shows precipitation patterns that date back to 1983 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 years old. 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. 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. 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.

Pinus longaeva

Pinus longaeva (commonly referred to as the Great Basin bristlecone pine, intermountain bristlecone pine, or western bristlecone pine) 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 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.

Bristlecone pine

The term bristlecone pine covers three species of pine tree (family Pinaceae, genus Pinus, subsection Balfourianae). 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. Despite their potential age and low reproductive rate, bristlecone pines, particularly Pinus longaeva, are usually a first-succession species, tending to occupy new open ground.

Pine

A pine is any conifer tree or shrub in the genus Pinus (ˈpiːnuːs) of the family Pinaceae. Pinus is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere.
