This is a list of the oldest-known trees, as reported in reliable sources. Definitions of what constitutes an individual tree vary. Definitions of what constitutes an individual tree vary. In addition, tree ages are derived from a variety of sources, including documented "tree-ring" ( dendrochronological ) count core samples, and from estimates.
The Jurupa Oak, or Hurungna Oak, [1] [2] is a clonal colony of Quercus palmeri (Palmer's oak) trees in the Jurupa Mountains in Crestmore Heights, Riverside County, California. The colony has survived an estimated 13,000 years through clonal reproduction, [ 3 ] [ 4 ] [ 5 ] making it one of the world's oldest living trees . [ 5 ]
In forestry, the largest trees are measured by the greatest volume of a single stem, regardless of species. In that case, the General Sherman Tree is the largest unitary (single-stem) tree. While many emphasize that Pando is the largest clonal organism, other large trees, including Redwoods can also reproduce via cloning. Pando being the ...
On the one hand, the researchers found, trees in forests "desire" to grow as tall as possible to overtake neighboring trees and reach stronger sunlight. On the other hand, gravity makes it more and more difficult to haul water upwards from the roots to the canopy as the tree grows, and leaves thus become smaller near the top. They discovered ...

These trees are also among the longest-living trees on Earth. Before commercial logging and clearing began by the 1850s, this massive tree occurred naturally in an estimated 810,000 ha (2,000,000 acres) [ 5 ] [ 6 ] [ 7 ] along much of coastal California (excluding southern California where rainfall is not sufficient) and the southwestern corner ...
While it is the largest tree known, the General Sherman tree is neither the tallest known living tree on Earth (that distinction belongs to Hyperion, a coast redwood), [8] nor is it the widest (both the largest cypress and largest baobab have a greater diameter), nor is it the oldest known living tree on Earth (that distinction belongs to Prometheus, a Great Basin bristlecone pine).

Hyperion is a coast redwood (Sequoia sempervirens) in California that is the world's tallest known living tree, measured at 116.07 metres (380.8 ft) tall in 2019. [1] [3] Hyperion was discovered on August 25, 2006, by naturalists Chris Atkins and Michael Taylor. [4]
