The Knobcone Pine (Pinus attenuata) 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. This pine reaches heights of 8-24 m; however, it can be a shrub on especially poor sites. It prefers dry rocky mountain soils. The crown is usually conical with a straight trunk. The bark is smooth, flaky and gray-brown when young, becoming dark gray-red-brown and shallowly furrowed into flat scaly ridges. The twigs are red-brown and often resinous.
