Species: P. attenuata. Binomial name. Pinus attenuata. Lemmon. The knobcone pine, Pinus attenuata (also called Pinus tuberculata), [2] is a tree that grows in mild climates on poor soils. It ranges from the mountains of southern Oregon to Baja California with the greatest concentration in northern California and the Oregon-California border.
The term bristlecone pine covers three species of pine tree (family Pinaceae, genus Pinus, subsection Balfourianae). All three species are long-lived and highly resilient to harsh weather and bad soils. One of the three species, Pinus longaeva, is among the longest-lived life forms on Earth. The oldest of this species is more than 4,800 years ...

P. radiata is a coniferous evergreen tree growing to 15–30 m (50–100 ft) tall in the wild, but up to 60 m (200 ft) in cultivation in optimum conditions, with upward pointing branches and a rounded top. The leaves ("needles") are bright green, in clusters of three (two in var. binata), slender, 8–15 cm (3–6 in) long and with a blunt tip.

Researchers in Chile identify a challenger to the world's oldest tree: an alerce in Alerce Costero National Park that may be over 5,000 years old. California's 'Methuselah' bristlecone pine may no ...
A Closed-cone conifer forest or woodland is a plant community occurring in coastal California and several offshore islands. The forests typically have a single-aged single-species conifer overstory with dense ladder fuels. Overstory species include coulter pine, monterey pine, bishop pine, shore pine, and several endemic cypresses, species ...
