Yellow pine forest
Yellow pine forest is a montane ecosystem plant community that is dominated by one or both of the "yellow pines": Ponderosa pine (Pinus ponderosa) and/or Jeffrey pine (Pinus jeffreyi).[1]:4[2]
Jeffrey pine is more stress tolerant than Ponderosa pine. At higher elevations, on poorer soils, in colder climates, and in dryer climates, Jeffrey pine replaces ponderosa as the dominant tree ("Jeffrey pine forest").[1] Ponderosa pine dominated forests ("Ponderosa pine forest") occur at elevations from about 300 to 2,100 metres (980 to 6,890 ft). Jeffrey pine dominated forests occur mostly in California, from 1,500 to 2,400 metres (4,900 to 7,900 ft) in the north, and 1,700 to 2,800 metres (5,600 to 9,200 ft) in the south. The highest elevations are typically on the east side of the Sierra Nevada.[1] "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.[1]
Ponderosa pine forests occurs in the Colorado Plateau[3] and in the Sierra Nevada[2] of the western United States, as well as other parts of North America.
