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.
An older bristlecone pine was reportedly discovered by Tom Harlan in 2009, based on a sample core collected in 1957. According to Harlan, the tree was 5,062 years old and still living in 2010. Neither the tree nor the sample core could be located after Harlan's death in 2013. [4]
Old Tjikko originally gained fame as the "world's oldest tree". [1] Old Tjikko is, however, a clonal tree that has regenerated new trunks, branches and roots over millennia rather than an individual tree of great age. Old Tjikko is recognized as the oldest living Picea abies and the fourth-oldest known clonal tree.
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]
Researchers in Chile identify a challenger to the world's oldest tree: an alerce in Alerce Costero National Park that may be over 5,000 years old. California's 'Methuselah' bristlecone pine may no ...
While it has been on the list of oldest trees, this Alerce tree (Fitzroya cupressoides) is now rivalling others to be possibly the oldest tree in the world. [3] [4] [2] Jonathan Barichivich and Antonio Lara, of the Austral University of Chile, bored a partial hole into the tree as far as possible without damaging it. They used an increment ...
This standing tree may have died hundreds of years ago. Scientific matching of dead trees' growth rings with living ones has created a 9,000-year-long record. Bristlecone pines are known for attaining great ages. The oldest bristlecone pine in the White Mountains is Methuselah, which has a verified age of 4,856 years.
An Inland Empire city has approved a development project within 450 feet of the third oldest known living organism in the world — a sprawling, shrub-like oak tree that is more than 13,000 years old.
