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.
The trees of Closed-cone pine forest burned in every 25–50 years, and a few species including the knobcone pine (Pinus attenuata) are adapted to open the cones and release seeds for new growth following the heat of forest fires. However, as fire regulation and suppression becomes more effective these communities cannot renew themselves.

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.
Elevations generally are less than 3,500 feet (1,100 m). Forest and woodland types can include areas of Douglas-fir, ponderosa pine, canyon live oak, and knobcone pine, along with chaparral of chamise, deer brush, and manzanita. Along streams, cottonwoods, white alder, and willows occur. [7]

In the modern classification, they are placed into subgenus Strobus, yet they did not fit entirely well in either so they were classified in a third subgenus. In 1888 the Californian botanist John Gill Lemmon placed them in subgenus Pinus. In general, this classification emphasized cone, cone scale, seed, and leaf fascicle and sheath morphology ...
