Pinus longaeva

Pinus longaeva, commonly known as the Great Basin bristlecone pine, is a species of exceptionally long-lived pine tree native to the western United States. It thrives in high-altitude, arid mountainous regions where few other trees survive. These trees are known for their remarkable age, with some individuals living over 5,000 years, making them among the oldest living organisms on Earth. They have dense, resinous wood that helps prevent decay and withstand harsh conditions. Their slow growth rate and resilience to extreme environments contribute to their longevity and scientific interest.
