Spruce-fir

In our region this community is represented only by a small patch in the highest elevations of the Pinaleño Mountains in southeastern Arizona, its southernmost location in North America. Here it occurs generally above 2800 meters⁽¹⁾ and is represented by the dominate tree species Engelmann spruce and subalpine or "corkbar" fir. This vegetation community is in danger in the Pinaleño Mountains due to climate change/drought and fire regime changes in the last century.
