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.

The core is sanded and treated with a wood oil to make the rings more distinct.

The 1906 ring pattern in wood Sample A (which was cut from Stump A) correlates with a 1906 ring pattern in Sample B which was cut from an older, undated Stump B. By matching up similar spaced rings in Samples B, C and D, the ages of ancient timbers can be determined.

As long as the wood samples being compared have some ring patterns that coincide, time may be extended back through an unbroken succession of growth rings.

This is a list of the oldest-known trees, as reported in reliable sources.

Definitions of what constitutes an individual tree vary.

Many of these trees may be even older than their listed ages, but the oldest wood in the tree has rotted away.

Since the rings are so close together, they must be counted under a dissecting microscope.
