Subalpine Ecosystem - U.S. National Park Service
Jul 5, 2022 · The subalpine ecosystem occupies elevations just below tree-line between 9,000 and 11,000 feet. A typical subalpine forest may consist mostly of subalpine fir and Engelmann spruce. However, previously-burned areas may contain varying amounts, or even almost pure stands, of lodgepole pine.

Subalpine forests | US Forest Service Research and Development
The subalpine forests of California comprise the highest elevation ecosystems that are dominated by upright trees. They are defined as a zone influenced primarily by abiotic controls, including persistent snowpack, desiccating winds, acute and chronic extreme temperatures, soil moisture and evapotranspirative stresses, and short growing seasons.
North America's subalpine forest ecosystems vary in altitude according to latitude and other geo- graphic considerations. Elevation ranges from about 2,600 m to 3,200 m in the middle Rockies; but is lower (1,300-1,900 m) in the northern Rockies, Blue Moun- tains, and northern Cascades (Romme and Knight 1981, MacMahon and Anderson 1982, Peet 1988).
