The bristlecone pine's root system is mostly composed of highly branched, shallow roots, while a few large, branching roots provide structural support. The bristlecone pine is extremely drought tolerant due to its branched shallow root system, its waxy needles, and thick needle cuticles that aid in water retention. [8] Gnarled bristlecone pine wood
Methuselah is a Great Basin bristlecone pine that is 4,856 years old and has been credited as the oldest known living non-clonal organism on Earth. [6] To protect it, the exact location of this tree is kept secret. In 1987, the bristlecone pine was designated one of Nevada's state trees. [7]
Pinus aristata is a medium-size tree, commonly reaching 15 meters (49 ft) in height and occasionally as much as 20 m (66 ft) in their natural habitat.In favorable conditions they are straight and upright trees, but they become increasingly stunted, short, and twisted the closer they grow to timberline.

Many pine trees turn yellow this time of year because of normal “needle drop” on the inside branches
A dendrochronology, based on these trees and other bristlecone pine samples, extends back to about 9000 BC, albeit with a single gap of about 500 years. [20] [3] 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 ...
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.
The Methuselah Grove in the Ancient Bristlecone Pine Forest is the location of the "Methuselah", a Great Basin bristlecone pine that is 4,856 years old. [7] It is considered to be the world's oldest known and confirmed living non-clonal organism. It was temporarily superseded by a 5,062 year old bristlecone pine discovered in 2010.
Once the pine cones are collected, they're brought to a network of nurseries, where the seeds are extracted and grown into seedlings. One million seedlings will plant about 4,500 acres of new forest.
