White Fir
Abies concolorAlso known as Concolor Fir, Colorado Fir, Silver Fir, Rocky Mountain White Fir
White fir is a stately montane conifer recognized by long, silvery blue-green needles that curve outward from pale grey twigs like gentle sickles. Mature trees develop thick, deeply furrowed ash-grey bark that provides modest insulation against low-intensity ground fires. Dense branches provide vital winter shelter and thermal cover for mule deer, porcupines, and songbirds across western mountain ranges.
