Great Basin Bristlecone Pine (Pinus longaeva)

General: Great Basin Bristlecone Pines (Pinus longaeva) are coniferous (cone-bearing) trees with short, dark green, roundish needles set in bundles of five. The needle-bundles are crowded onto the ends of twigs, and the bundles radiate in all directions from the twigs, giving the branch a "bottle-brush" appearance. Cones are sappy, prickly, cylindrical, and about 4-inches long. Great Basin Bristlecone Pines are closely related to Foxtail Pines.

In Nevada, Great Basin Bristlecone Pine is the dominant component of the montane vegetation in the Spring and Sheep mountains in the Hudsonian (Bristlecone Forest) life zone. On Mt. Charleston, a popular 3-mile hike runs out to the Raintree, a 3000-year-old Bristlecone Pine.

For many more photos of bristlecone pine, see the North Loop Trail (Mt. Charleston) webpage.

Family: Pine (Pinaceae).

Other Names: Western Bristlecone Pine, Pinus aristata.
