Great Basin bristlecone pine

Great Basin bristlecone pines are restricted to the mountain ranges of California, Nevada and Utah and have a remarkable ability to survive in this extremely harsh and challenging environment. They grow extremely slowly, and are some of the oldest living organisms in the world. With some aged at almost 5,000 years these amazing trees can reveal information about Earth's climate variations. Amazingly, the leaves, or needles, can remain green for over 45 years.
