Pando, a colony of quaking aspen, is one of the oldest-known clonal trees. Recent estimates of its age range up to 14,000 years old, and 18,000 years by the latest (2024) estimate. [1] It is located in Utah, United States. This is a list of the oldest-known trees, as reported in reliable sources. Definitions of what constitutes an individual ...
The tree's age was determined by carbon-14 dating of the root system, which found roots dating back to 375, 5,660, 9,000, and 9,550 years before 2008. [7] Carbon dating is not accurate enough to pin down the exact year the tree sprouted from seed; however, given the estimated age, the tree is supposed to have sprouted around 7550 B.C.
The claim that Methuselah is the oldest known tree is controversial. Methuselah was 4,789 years old when sampled in 1957 [13] by Edmund Schulman and Tom Harlan, [1] with an estimated germination date of 2833 BC. Dendrochronologist Matthew Salzer of the University of Arizona has been unable to reproduce Schulman's age estimate, due to a missing ...
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 ...
Extreme drought and bark beetles now threaten California's Ancient Bristlecone Pine Forest, home to Methuselah, a 4,853-year-old bristlecone pine.
A Palmer oak in Jurupa Valley is estimated to be 13,000 to 18,000 years old. The plant, which looks like a sprawling, dark green shrub, is now at the center of a development battle.
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.
