Jeffrey pine is more stress tolerant than ponderosa pine in the Sierra Nevada. At higher elevations, on poorer soils, in colder climates, and in drier climates, Jeffrey pine replaces ponderosa as the dominant tree (Jeffrey pine forest). Ponderosa pine-dominated forests (Ponderosa pine forest) occur at elevations from about . Jeffrey pine-dominated forests occur mostly in California, from in the north, and in the south. The highest elevations are typically on the east side of the Sierra Nevada. Eastside pine forest refers to areas of Lassen National Forest, Plumas National Forest, and Tahoe National Forest, all on the east of the Sierra Nevada crest, where ponderosa and Jeffrey pine codominate.
