Subalpine Fir Range

USFS/Little
Abies lasiocarpa is a high altitude western North American fir, native to the mountains of western Canada, the Unites States Pacific Northwest, and the Intermountain Western Rockies. The tree occurs at high altitudes and is commonly found at the tree line.

Throughout much of the Rocky Mountains, subalpine fir has no special or unique properties. In the high Cascades and in the Rocky Mountains of Idaho and Montana, it is a forest pioneer on severe and disturbed sites. By providing cover, subalpine fir assists in protecting watersheds and rehabilitating the landscape. Forests in which subalpine fir grows occupy the highest water yield areas in much of the West.
