Tree House Clapham – Methuselah, Bristlecone Pine, Pinus longaeva (usually known as the Great Basin bristlecone pine, intermountain bristlecone pine, or western bristlecone pine) is a long-residing species of bristlecone pine tree discovered withinside the better mountains of California, Nevada, and Utah. Methuselah is a bristlecone pine this is 4,853 years vintage and has been credited because the oldest recognised residing non-clonal organism on Earth. To guard it, the precise region of this tree is stored mystery. In 1987, the bristlecone pine turned into exact one in every of Nevada’s country bushes.

The oldest bushes withinside the international are the bristlecone pines (Pinus longaeva) of California’s White Mountains, USA. The oldest named person tree, christened “Methuselah”, turned into discovered with the aid of using Dr Edmund Schulman (USA) and dated in 1957 from center samples as being greater than 4,800 years vintage (4,852 years as of 2020); this age turned into later crossdated and showed with the aid of using dendrochronologist Tom Harlan (d. 2013) on the Laboratory of Tree-Ring Research on the University of Arizona. An even older specimen of bristlecone sampled with the aid of using Schulman withinside the White Mountains earlier than he died turned into additionally crossdated with the aid of using Tom Harlan, however now no longer till 2009. This pattern turned into additionally from a residing tree, so the tree is elderly 5,070 years as of 2020; this unnamed tree is presently the oldest proven residing tree withinside the international. The particular places of those bushes are stored mystery to guard them from vandalism/harm from over-trampling. The annual increase jewelry of vintage bushes offer a treasured perception into our converting weather: the bristlecone weather document from lifeless wooden extends returned greater than 9,000 years. The Ancient Bristlecone Pine Forest is placed at round 3,050 metres (10,000 feet) above sea stage withinside the White Mountains, east of the Sierra Nevada. Over time, the wind and rain has moulded the bushes into unusual shapes and bureaucracy made even greater uncommon with the aid of using the sunshine, altitude and crisp air. Dr Schulman turned into a scientist from the University of Arizona while he got here throughout Methuselah and a place withinside the wooded area is known as the Schulman Grove in his honour.
Methuselah is classified as “person” because it isn’t a clone. It is uncommon for any person tree to exceed 3,000–4,000 years vintage.
Other long-lived person tree species include: large sequoia (Sequoiadendron giganteum, western juniper (Juniperus occidentalis and Patagonian cypress (Fitzroya cupressoides), all of that have had specimens elderly to among 3,000–4,000 years and over.
There are older examples of clonal plants. For instance, a creosote bush (Larrea tridentata) discovered in 1980 withinside the wasteland close to Palm Springs, California, USA – elderly at 11,seven-hundred years vintage – is a clone, as person specimens of this species hardly ever exceed two hundred years. Some scientists have cautioned that the clonal wooded area of quaking aspen (Populus tremuloides), called Pando, withinside the Wasatch Mountains of Utah, USA (the international’s maximum big unmarried plant and heaviest organism) ought to date returned as some distance as 14,000 years, which could additionally make it the international’s oldest residing organism, however that is extensively debated and unconfirmed at this point.
Similarly, lifeless wooden retrieved from the bottom of a Norway spruce (Picea abies), dubbed “Old Tjikko”, in Dalarna Province, Sweden, has been radiocarbon-dated to as vintage as 9,550 years. However, this too could be an instance of vegetative cloning in preference to an person tree of this age, as spruce bushes are notion to simplest stay for, at maximum, some centuries. Further, extreme doubts had been solid that the lifeless wooden is genetically related to the contemporary residing specimen (Mackenthun, 2016; Farjon, Oct 2015), so it can be from a distinct spruce that previously existed at the identical site.
