Dominant Species: Engelmann Spruce (Picea engelmannii) and Subalpine fir (Abies lasiocarpa).
Description: Spruce fir forest not significantly affected by logging. Engelmann spruce and/or subalpine fir must be dominant or co-dominant in the canopy. This type will also include spruce fir krummholz communities. Total canopy coverage by all tree species must be greater than 25%.
Distribution: Abies lasiocarpa and Picea engelmannii are found in the subalpine zone throughout the state of Colorado. The subspecies A.l. arizonica begins to replace the subspecies A.l. lasiocarpa in the southern part of the state. Abies is absent from the relatively dry subalpine zone of Pike's Peak.
Elevation Range: 2590-3659m (8500 - 12000')
