LIST OF OLDEST TREES

This is a list of the oldest known trees, as reported in reliable sources. Definitions of what constitutes an individual tree vary. In addition, tree ages are derived from a variety of sources, including documented "tree-ring" count core samples, and from estimates. For these reasons, this article presents three lists of "oldest trees," each using varying criteria.

Pando an 80,000-year-old colony of quaking aspen, is the oldest known clonal tree, located in Utah, United States.

There are three tables of trees, which 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 centre 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 current 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 more than five millennia old.

A clonal colony can survive for much longer than an individual tree. A colony of 47,000 quaking aspen trees (nicknamed "Pando"), covering 106 acres (43 ha) in the Fishlake National Forest of Utah,  is considered one of the oldest and largest organisms in the world. The colony has been estimated to be 80,000 years old, although tree ring samples date individual, above-ground, trees at only an average of about 130 years. A colony of Huon pine  trees covering 2.5 acres (1.0 ha) on Mount Read, Tasmania 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 in the sense of active metabolism) 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 (years)	Species	Location	Notes
Pando	80,000-1,000,000	Quaking aspen, Populus tremuloides	Fishlake National Forest, Utah, United States	Covers 107 acres (0.43 km2) and has around 47,000 stems (average age 130 years), which continually die and are renewed by its roots. Is also the heaviest known organism, weighing 6,000 tonnes.
Jurupa Oak.	13,000	Palmer oak, Quercus palmeri	Jurupa Mountains, California, United States.	Quercus palmeri Engelm. = Quercus dunnii Kellogg.

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	9,500	Norway spruce, Picea abies	Härjedalen, Sweden	[45]
?	3,000 - 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.

Notes

1. ^ It is uncertain when Methuselah's age was determined, but "it seems likely the tree had 4,789 rings (crossdated) in the summer of 1957". The age given here is based on this reference point.
