List of oldest trees

This is a list of the oldest-known trees. Definitions of longevity vary between clonal trees, ones where parts of the tree continue to live after the death of the first trunk or trunks, and non-clonal trees. Tree ages are derived from a variety of sources, including documented "tree-ring" count core samples, radiocarbon dating, girth-to-age formulas, and estimates from growth rates. For these reasons, there are three lists of "oldest trees" here, using different criteria.
The three tables of trees are listed by age and species. The first table includes trees for which a minimum age has been directly determined, either through counting or cross-referencing tree rings or through radiocarbon dating. Many of these trees may be even older than their listed ages, but the oldest wood in the tree has rotted away. For some old trees, so much of the center is missing that their age cannot be directly determined. Instead, estimates are made based on the tree's size and presumed growth rate. The second table includes trees with these estimated ages. The last table lists clonal colonies in which no individual tree trunks may be remarkably old but in which the organism as a whole is thought to be very old.
The record-holders for individual, non-clonal trees are the Great Basin bristlecone pine trees from California and Nevada, in the United States. Through tree-ring cross-referencing, they have been shown to be almost five millennia old.
A clonal colony can survive for much longer than an individual tree. A colony of 48,000 quaking aspen trees, covering in the Fishlake National Forest of Utah, is considered one of the oldest and largest organisms in the world. Recent estimates set the colony's age at about 16,000 to 80,000 years, although tree ring samples date individual stems at rarely more than 130 years. A colony of Huon pine trees covering on Mount Read is estimated to be around 10,000 years old, as determined by DNA samples taken from pollen collected from the sediment of a nearby lake. Individual trees in this group date to no more than 4,000 years old, as determined by tree ring samples.

Clonal trees

As with all long-lived plant and fungal species, no individual part of a clonal colony is alive for more than a very small fraction of the life of the entire clone. Some clonal colonies may be fully connected via their root systems, while most are not actually interconnected, but are genetically identical clones which populated an area through vegetative reproduction. Ages for clonal colonies, often based on current growth rates, are estimates.

Name	Age	Species	Location	Country	Notes
Wollemi Pines		Wollemi pine Wollemia nobilis	Wollemi National Park, New South Wales	Australia	According to Cris Brack and Matthew Brookhouse at the ANU Fenner School of Environment & Society: "Once you accept that a common, genetically identical stock can define a tree, then the absolute "winner" for oldest tree must go to the Wollemi pine. It may be more than 60 million years old. The Wollemi pine clones itself, forming exact genetic copies. It was thought to be extinct until a tiny remnant population was discovered in Wollemi National Park in 1994... There is also substantial evidence that the tree has been cloning itself and its unique genes ever since it disappeared from the fossil record more than 60 million years ago."
Unknown		King's lomatia Lomatia tasmanica	Southwest National Park, Tasmania	Australia	Lomatia tasmanica is an endangered species with only one population, consisting of several hundred genetically identical individuals. Although it flowers occasionally, fruit production has never been observed, and it propagates vegetatively. Fossilized leaves are dated as at least 43,600 years old, found in sediments with a maximum age of 130,000.
Pando		Quaking aspen Populus tremuloides	Fishlake National Forest, Utah	United States	Covers and has around 47,000 stems, which continually die and are renewed by its roots. Is also the heaviest-known organism, weighing 6,000 tonnes.
Jurupa Oak		Palmer oak Quercus palmeri	Jurupa Mountains, California	United States	Quercus palmeri Engelm. = Quercus dunnii Kellogg.
Old Tjikko		Norway spruce Picea abies	Fulufjället National Park, Dalarna	Sweden	The tree's stems live no more than 600 years, but its root system's age was established using carbon dating and genetic matching. Elsewhere in the Fulu mountains, 20 spruces have been found older than 8,000 years.
Old Rasmus		Norway spruce Picea abies	Sonfjället, Härjedalen	Sweden
Mongarlowe mallee		Mongarlowe mallee Eucalyptus recurva	Mongarlowe, New South Wales	Australia	Alive. A critically endangered species, known only from 6 wild individuals, first described in the 1980s. Based on the size and growth rate of its lignotuber, the largest single specimen is estimated to be 3,000 years old. However, it is possible that two other specimens are actually the result of a split in the original rootstock, and based on their spread of 26m would be estimated at 13,000 years old, potentially the oldest single tree on earth.
unknown	–10,000	Huon pine Lagarostrobos franklinii	Mount Read, Tasmania	Australia	Several genetically identical males that have reproduced vegetatively. Although single trees in this stand may be around 3 to 4 thousand years old, the stand itself as a single organism has existed for 10,000 years.
Antarctic Beech		Antarctic beech Nothofagus moorei	Repeater Station Road, Springbrook National Park, Queensland	Australia	Three individuals approximately 2000 years old are the parent trees to others in the surrounding forest; they grow clones by coppicing new shoots radially, forming a ring at the base of the parent tree trunk.
