Bristlecone Pine

The oldest known living individual tree on Earth, the Great Basin bristlecone pine can live over 5,000 years in the harsh, windswept subalpine environments of the White Mountains of California and the Great Basin region. Their extreme longevity is linked to slow metabolism, dense resinous wood resistant to decay and insects, and harsh high-altitude conditions that limit competition. Tree ring records from bristlecone pines have provided an invaluable climate proxy record extending back thousands of years.
