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
Ponderosa pine: Pinus ponderosa: 1949 [34] Nebraska: Eastern cottonwood: Populus deltoides: 1972 [35] Nevada: Single-leaf pinyon: Pinus monophylla: 1959 [36] Great Basin bristlecone pine: Pinus longaeva: 1987 [36] New Hampshire: American white birch: Betula papyrifera: 1947 [37] New Jersey: Northern red oak: Quercus rubra: 1950 [38] New Mexico ...
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 It was temporarily superseded by a 5,062 year old bristlecone pine discovered in 2010.
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.
White fir, Douglas fir, and ponderosa pines are found in the middle elevations of some mountain ranges, while limber pine, subalpine fir, Engelmann spruce, and bristlecone pines occupy the higher elevations, continuing to the upper tree line. Mountain mahogany often dominates drier, warmer south-facing slopes. [3]
Pinus, the pines, is a genus of approximately 111 extant tree and shrub species. The genus is currently split into two subgenera: subgenus Pinus (hard pines), and subgenus Strobus (soft pines). Each of the subgenera have been further divided into sections based on chloroplast DNA sequencing [1] and whole plastid genomic analysis. [2]
The Great Basin is also home to the oldest species in the world, the bristlecone pine (Pinus longaeva). Its needles allow it to retain water and use very little of it during its lifetime. It is able to grow on exposed rocky surfaces in higher elevations about forested areas.
