One species of bristlecone pine, the Great Basin bristlecone, lives longer than any other tree. It is found at the timberline in the mountains of California, Nevada, and Utah. Dense, resinous wood and slow growth help keep the trees from drying out and protect the bristlecones from insects, harmful bacteria, and fungi.
The oldest living tree, at 4,765 years old, is a bristlecone pine named “Methuselah,” growing in the White Mountains of California.
Bristlecone pines thrive in exposed, rocky, and harsh environs. Wind and snow at high elevations distort the crowns of the trees. At 8,000 to 11,000 feet, there are years where temperatures do not rise above freezing. This prevents the trees from putting on a new year’s growth. However, bristlecone pine needles can stay on a limb for more than 40 years. In this way, the trees can survive successive years of drought or extreme cold until new leaves can grow again.
A bristlecone pine can survive even if most of its branches and roots die. Blowing sand and ice crystals will polish the trunk and wear away parts of the tree. In an ancient tree, a thin strip of living bark may be all that joins the roots with the few live branches still on the tree. And that is enough – the bristlecone lives on.
