Which tree species dominates the ancient bristlecone pine groves of California’s White Mountains?

The Great Basin bristlecone pine, Pinus longaeva, dominates the ancient bristlecone pine groves of California’s White Mountains.

These trees survive in high, dry environments near and above the timberline, where cold temperatures, thin soils, strong winds and short growing seasons limit competition. Their slow growth produces dense, resin-rich wood that resists insects and decay. When part of a tree dies, the remaining living strip can continue growing for centuries.

The species is celebrated for extreme longevity. Individual trees are among the oldest known non-clonal organisms, and some have been dated to more than 4,800 years. “Methuselah” is the traditional name given to one especially old individual, although its exact location is kept secret to protect it.

Great Basin bristlecone pine is different from the Rocky Mountain bristlecone pine, Pinus aristata, which has a separate range and generally does not reach the same recorded ages.
