On the coast, the knobcone pine may hybridize with bishop pine (Pinus muricata), and Monterey pine (Pinus radiata). In the western foothills of the Sierra Nevada, knobcone pine is often a co-dominant with blue oak (Quercus douglasii). [7] The species is susceptible to fire, but this melts the cone resin, releasing seeds for regrowth. [4]

The most widespread naturally of the closed-cone pines is bishop pine (Pinus muricata), which can be found along the coast from Humboldt County, California in the north to the northwestern corner of Baja California in the south. Knobcone pine (Pinus attenuata) forests can occur further inland, on dry, rocky soils.
Arceuthobium siskiyouense is a species of dwarf mistletoe known as knobcone pine dwarf mistletoe. It is endemic to the Klamath Mountains of northern California and southern Oregon, where it lives as a parasite on knobcone pine trees. This is a brownish shrub which is visible as a network of scaly stems extending above the bark of its host tree.
Pinus muricata forest growing at Point Reyes, California. Closed-cone conifer forests are found in small, scattered patches throughout the ecoregion, typically adjacent to maritime chaparral. Common pines are lodgepole pine (Pinus contorta), bishop pine (Pinus muricata), Monterey pine (Pinus radiata), and knobcone pine (Pinus attenuata).

Unusually for a pine, the cones normally point forward along the branch, sometimes curling around it. That is an easy way to tell it apart from the similar lodgepole pine in more western areas of North America. The cones on many mature trees are serotinous. They open when exposed to intense heat, greater than or equal to 50 °C (122 °F). [16]
