The Great Bristlecone pine

- THE OLDEST TREE EVER FOUND IN THIS EARTH …..

HELLO FRIENDS , WELCOME !!!!

TODAY WE , UPON STARTING THE LESSON – DIVERSITY IN LIVING ORGANISMS ARE GOING TO SEE ABOUT ‘ THE GREAT BRISTLE CONE PINE ‘ from the kingdom PLANTAE

A SHORT INTRO TO BRISTLE CONE PINE { SCIENTIFIC CLASSIFICATION }

Kingdom : Plantae

Division: Pinophyta

Class: Pinopsida

Order: Pinales

Family: Pinaceae

BRISTLE CONE PINE…

The bristlecone pines are one of the world’s oldest living organisms  the oldest known living tree is called ‘Methuselah’ and has been dated at a mighty 4,789 years of age  These ancient trees have a fittingly gnarled and stunted appearance, especially those found at high altitudes, and have reddish-brown bark with deep fissures The green pine needles give the twisted branches a bottle-brush appearance. The name bristlecone pine refers to the dark purple female cones that bear incurved prickles on their surface

their root systems. Bristlecones are only found in six states, Utah included. The oldest LIVING tree is called "Methuselah" and is 4,765 years old. This tree is nearly 1,000 years older than any other bristlecone alive today. It lives in a secret location in the White Mountain range of eastern California. The oldest known tree named "Prometheus" was cut down in 1964 by a doctoral student. He was studying climate change as expressed in receding glaciers whose historic size could be measured by influence on the growth rings of nearby ancient bristlecones. This happened in what is now known as Great Basin National Park. The tree was later confirmed to be almost 4,900 years old. 

Bristle cones have 5 needles per fascicle, and can grow to be 40-60 feet in height (under most favorable conditions.) Often they will die in portions. As the roots become exposed they will dry out and die. The tree directly connected above those roots will eventually die as well. The remainder of the tree will continue to live. This is among the causes that create the twisted tortured look of the trees. It also may prompt the question "why do they take so long to die?" as opposed to "why do they live so long?" 

Bristlecone pine is also known as "Wind Timber", "Hickory Pine", "Krummholz" and "Foxtail Pine." It is a member of the group of pines known as foxtail pines, because of the shape of the branches and the way the needles stay attached all the way up the limb. The limbs look like small foxtails. 

In recent decades, two species of bristlecone have been distinguished. Pinus longaeva is called the Great Basin Bristlecone. Pinus aristata is the Rocky Mountain Bristlecone. The biological distinction is based on the numbers of resin ducts per needle, which are difficult to see even with a powerful hand lens.
