Lack of fire has profoundly changed forest structure across the region, significantly increasing true fir occurrence and density. The recent drought and bark beetles have led to a large mortality event.
Primary purpose of salvage harvesting is to recover the economic value of trees killed or damaged by unforeseen and uncontrollable events (insects, wildfire, wind, ice & snow, volcanoes, etc.).
Extensive research on the fate of fire damaged trees provides guidance for assessing survival based on post-fire observations of crown scorch, bark char, and root damage.
