Pinus ponderosa
"Pinus jeffreyi" is more stress tolerant than "Pinus ponderosa". At higher elevations, on poorer soils, in colder climates, and in dryer climates, "Pinus jeffreyi" replaces "Pinus ponderosa" as the dominant tree. "Pinus jeffreyi" is also tolerant of serpentine soils and is often dominant in these conditions, even on dry sites at fairly low altitudes.
