Groves of knobcone pine can be found around Pleasants Peak. These isolated groves may include Ponderosa pine, Douglas fir, and knobcone pine. Jeffrey pine, knobcone pine, and golden chinquapin have also been identified. Knobcone pine is also common along some dry, rocky ridges. The knobcone pine ("Pinus attenuata") crown is usually conical with a straight trunk. Knobcone pine ("Pinus attenuata") forests can occur further inland, on dry, rocky soils.
