Coulter pine is an indicator of serpentine soils, but also occurs on a variety of other substrates. Soils range from loamy to gravelly or rocky in texture. [15] [16] [17] Coulter pine occurs between 500 to 7,000 feet (150-2,120 m) elevation. [18] [19]
Overstory species include coulter pine, monterey pine, bishop pine, shore pine, and several endemic cypresses, species which generally rely on fire to open their cones and release seeds. Closed-cone forests often grow in low nutrient and/or stressed soils, which can lead to slow growth.
Coulter pine (Pinus coulteri) or; Gray pine (Pinus sabiniana) Common wildlife include Steller's jay, chestnut-backed chickadee, western gray squirrel, raccoon and many others. These forests are more diverse in animal life than those having only conifers. The predominance of broadleaf trees provide a greater abundance of food sources.
The gray pine (Pinus sabiniana) and rarer Coulter pine (Pinus coulteri) can be found at all elevations, especially between 800–3,000 feet (240–910 m). Coulter pine reaches its northern limit on northern of Mt. Diablo.
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.
It is dominant by interior live oaks (Q. wislizeni), blue oaks, foothill pine, and shrubs in common with blue oak woodland. Valley oak woodland is found in the interior valleys of northern, central and southern California, and is dominated by valley oak and coast live oak, together with gray pine and Coulter pine (Pinus coulteri).

Montane forests are generally pine and fir dominated communities that occur at higher elevations in southern California’s mountain areas from 3000 up to 8500 ft. At the lower parts of the range, dominant trees include big-cone Douglas fir and Coulter pine as well as canyon live oak and California bay.
