Winter rains are infrequent, and the summer is dry with occasional summer thunderstorms. [3] It is a native of the coastal mountains of Southern California in the United States and northern Baja California in Mexico.

The higher elevation Madrean Sky Islands are dominated by pinyon pine and California juniper (Juniperus californica), with areas of Manzanita and Coulter pine (Pinus coulteri). More than half of the Colorado Desert's plant species are herbaceous annuals, and appropriately timed winter rains produce abundant early Spring wildflowers. In the ...
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.
Subsection Ponderosae is native to Central America, Mexico, the western United States, and southwestern Canada, [4] [13] although its former range was possibly much wider as evidenced by upper Miocene fossils belonging to this subsection found in Japan [14] P. arizonica – Arizona pine; P. cooperi – Cooper's pine; P. coulteri – Coulter pine
Jeffrey pine wood and ponderosa pine wood are sold together as yellow pine. [10] Both kinds of wood are hard (with a Janka hardness of 550 lbf (2,400 N)), but the western yellow pine wood is less dense than southern yellow pine wood (28 lb/cu ft (0.45 g/cm 3 ) versus 35 lb/cu ft (0.56 g/cm 3 ) for shortleaf pine).
A developed hardwood forest and mixed community of Valley Oak (Quercus lobata) and Coulter pine (Pinus coulteri) thrives on the slopes of Chews Ridge. The ridge unusually supports extensive areas of savanna with large valley oaks, with many patches of open grassland than other peaks in the Santa Lucia Range.
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.
