Crowsnest Firesthe fallout
• Example: Spray Lake Sawmills • Benefits:
– able to use a significant amount of the burnt lumber.– With large salvage quota (28%) able to ensure burnt
lumber not wasted
• Difficulties:– Root scorch– cost of accessibility– Debarking dilemma
• burnt bark is not useable but de-barking the trees will keep the chips clean and reduce the carbon content.

Crowsnest Firesthe fallout: Ecological Pros and Cons
Positive• Certainly a burned area is
black and looks devoid of life.
• A burned area creates ecological diversity and allows for the development of rich undergrowth that wasn’t there before.
Negative• Over time burned area
creates diversity that wasn’t there before
• Large stands of timber smother the light and inhibit undergrowth – even though large stands of trees are aesthetically pleasing and profitable for the lumber industry.
