Pinus longaeva (commonly referred to as the Great Basin bristlecone pine, intermountain bristlecone pine, or western bristlecone pine) is a long-living species of bristlecone pine tree found in the higher mountains of California, Nevada, and Utah. Methuselah is a bristlecone pine that is 4,855 years old and has been credited as the oldest known living non-clonal organism on Earth. To protect it, the exact location of this tree is kept secret. In 1987, the bristlecone pine was designated one of Nevada's state trees.
