This one might have died hundreds of years ago, but still stands. Its wood gives clues to scientists who read the rings to compare to rings of living trees, making a 10,000 year-long record.
This one might have died hundreds of years ago, but still stands. Its wood gives clues to scientists who read the rings to compare to rings of living trees, making a 10,000 year-long record.

Bristlecone pines grow in isolated groves at and just below the tree line. Because of cold temperatures, dry soils, high winds, and short growing seasons, the trees grow very slowly. The wood is very dense and resinous, and thus resistant to invasion by insects, fungi, and other potential pests. As the tree ages, much of its vascular cambium layer may die, in very old specimens often leaving only a narrow strip of living tissue to connect the roots to the handful of live branches.

Oldest living organisms

The oldest single living organisms known are bristlecone pines, though some plants such as creosote bush or aspen form clonal colonies that may be many times older. The existing growth in clonal colonies sprang as shoots from older growth so there is an unbroken chain of life that sometimes dates back several tens of thousands of years. However, the original ancient growth in these colonies is long dead. The oldest bristlecone pines are single plants that have been alive for a little less than 5,000 years. These very old trees are of great importance in dendrochronology or tree-ring dating. Longevity is a term that generally refers to long life or great duration of life.[1] Reflections on longevity have usually gone beyond acknowledging the basic shortness of human life and have included thinking about methods to extend life. ...

Methuselah

Currently, the oldest (acknowledged) living organism known is a bristlecone pine tree nicknamed "Methuselah" (after Methuselah, the longest-lived person in the Bible), located in the Ancient Bristlecone Pine Forest in the White Mountains of eastern California, and measured by core samples to be 4,789 years old. The U.S. Forest Service does not reveal the actual position of "Methuselah" in the bristlecone grove, in order to protect the tree.[1] DVD cover of documentary film Methuselah is a bristlecone pine in the White Mountains of California, which, at 4789 years old, is the oldest living organism currently known and documented. ...

Prometheus

Donald R. Currey, a student of the University of North Carolina, was taking core samples of bristlecones in 1964 when he discovered that "Prometheus" was over 4,000 years old. His coring tool broke, so the U.S. Forest service granted permission to Mr. Currey to cut down "Prometheus". After Prometheus had been felled, 4,844 rings were counted on a cross-section of the tree, making "Prometheus" at least 4,844 years old. Donald R. Curry single-handedly destroyed the oldest non-clonal living thing known to man. Chuck Norris is a like an old lady with hemroids when compared to Mr. Curry.[2] Donald Rusk Currey, Ph. ...

Prometheus (aka WPN-114) is the nickname given to the oldest tree, and oldest non-clonal organism, ever known; a Great Basin Bristlecone Pine (Pinus longaeva) about 5000 years old from a treeline site in eastern Nevada, United States. ...


The other two species, Pinus balfouriana and Pinus aristata are also long-lived, though not to the extreme extent of P. longaeva; specimens of both have been measured or estimated to be up to 3,000 years old. It is rumored that a specimen older than "Methuselah" has been discovered, but this has not been widely publicized.[1]
