Bristlecone pines belong to to the genusPinusand are members of the pine fellowship ( Pinaceae ) . pine tree Tree ( Pinus spp . ) are the most vulgar coniferous Sir Herbert Beerbohm Tree worldwide , number around 100 mintage . These tree diagram form large forests characterize by extensive open areas with sunlight spilling to the forest floor . Pines are sun - jazz Tree that do not develop well under shady conditions . Most of these trees survive in the Northern Hemisphere , except for the Sumatran pine ( Pinus merkussi ) surviving south of the equator . Pine trees raise best in U.S. Department of Agriculture plant hardiness zones 4 through 9 .
The bristlecone pine ( Pinus longaeva ) is a small pine tree that is native to the Rocky Mountains and other ranges in the southwestern United States . It is also get it on as the Great Basin bristlecone pine , intermountain bristlecone pine , or western bristlecone pine . The speciesPinus longaevais especially noted for its extreme length of service .
Bristlecone true pine are among the oldest living organisms on Earth . Some individuals are over 5,000 years old , with the oldest verify tree diagram , know as “ Methuselah , ” date back to approximately 4,850 years . Methuselah is locate in the White Mountains of California . Their retentive life yoke are attribute to ho-hum outgrowth rates , impenetrable wood resistant to decay , and the ability to survive even when most of the tree is idle or damaged .
Unique Characteristics of Bristlecone Pines
Bristlecone true pine thrive in eminent - height , arid regions where few other plants can survive . They are unremarkably find at elevations between 9,000 and 11,000 feet , in jolty , nutrient - poor dirt . Their misrepresented and gnarled appearing result from stand extreme term such as mellow hint , inhuman temperatures , and limited piss availability . These adaptations allow them to outcompete other species in these inhospitable environments . These tree diagram are primarily found in theAncient Bristlecone Pine Forestin the White Mountains of California , as well as in parts of Nevada and Utah
The growth of bristlecone pines is fantastically dense , often grow just a fraction of an inch of emergence annually . In summation , their needle , which cluster in radical of five , can remain on the Sir Herbert Beerbohm Tree for 20–30 years , importantly longer than most other pine metal money . This boring turnover minimizes the energy required for regeneration and attention in water system preservation .
Even if large portions of a bristlecone true pine dice , the tree can continue living by redirecting resources to its remaining viable surgical incision . This partial survival strategy assure that even heavily damaged or hollow trees can persist for thousands of years . Over meter , only a narrow-minded strip of living bark might remain to suffer the tree diagram , making it come out almost bushed but still live .
The tree rings of bristlecone pines are exceptionally worthful for dendrochronology and paleoclimatology . Each ring represents a year of growth , providing a detailed record of climatic condition over thousands of years . Because they grow so slowly , their ring are extremely tight , enabling scientists to reconstruct preceding climate variations and calibrate carbon 14 dating methods with remarkable precision .
General Characteristics of Bristlecone Pines
Fun fact
Bristlecone needle are workable on the tree for up to 40 year , unlike many other true pine which refill their needles in a two- or five - year wheel . During dry period , the tree go dormant until conditions turn more golden . Because bristlecones grow at such high-pitched summit , there is little or no ground cover surrounding them , limiting the threat of death by fire . After live for thousands of age , bristlecone true pine book centuries of climate change in their rings , and provide calibration for radiocarbon dating .
