Description
Most of this site will have a mix stand of mature Douglas-fir, western larch, lodgepole pine and some subalpine fir and Engelmann spruce. Subalpine fir and Engelmann spruce will be the main understory tree species. Intermittent mix severity or ground fires will maintain a mixed stand. Severe stand replacing fires will lead to dense lodgepole stands with subalpine fir and Engelmann spruce regeneration underneath. Long fire intervals of 100 - 200 years will produce a fir/spruce climax forest. This seldom occurs.
