Subalpine fir

Subalpine fir (Abies lasiocarpa) also known as balsam fir, is a medium sized softwood tree which grows well at high elevations in the interior of British Columbia, Canada. It is one of the "true firs" and has smooth grey bark with resin blisters when young and can reach heights of 20 to 35 meters. Subalpine fir does not live long because of its susceptibility to wood-rotting fungi, especially Indian paint fungus and bleeding conk fungus. Between 120 and 140 years of age, many trees become infected and die.
