Oldest tree
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.
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 record-holders for individual, non-clonal trees may be 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 5,000 years 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 the United States, 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.

This Nonprofit Is Quietly Cloning the World's Largest (and Oldest) Trees
The 2,500-year-old Ankerwycke Yew, which sits near a medieval nunnery in Southern England, has borne witness to some serious history. It shaded the King of England during the signing of the Magna Carta. It was a favorite meeting spot of Anne Boleyn and King Henry. And it’s likely going to see a whole lot more, after the Archangel Ancient Tree Archive finishes cloning it.
