Official State Tree of Nevada
Nevada designated bristlecone pine as an official state tree in 1987 (single-leaf piñon was the first tree symbol of Nevada, adopted in 1953). All State Trees
From Nevada Legislature: "The bristlecone pine (Pinus longaeva) is the oldest living thing on Earth, with some specimens in Nevada more than 4,000 years old. The tree can be found at high elevations.
Normal height for older trees is about 15 to 30 feet, although some have attained a height of 60 feet. Diameter growth continues throughout the long life of the tree, resulting in massive trunks with a few contorted limbs."
