Mountain zones


Mountain zones and boundaries
Mountain slopes host a great variety of trees and plants according to elevation. Zone elevations move downward in cold, northern locations. In southern B.C., the alpine-subalpine boundary, discernible at the treeline, is found at the 1,800-m level; in the Yukon, it lies near the foot of the mountain.

Alpine zone. From the icy rock terrain on the mountaintop to the treeline: lichens, mosses, shrubs, sedges

Subalpine zone. From the treeline to the lower slopes: alpine fir, Engelmann spruce

Montane zone. On the densely forested lower slopes: lodgepole pine, Douglas fir, Douglas maple. At the mountain base lie the Parkland and Prairie zones
