Crowsnest Firesthe fallout

• Crowsnest Fire blaze (2003)– burned over 20,000 hectares of forest– Affecting:

• Timber industry, local businesses, tourism (especially hard hit

– But• local dry cleaners, gas stations, restaurants and office

services maintained a steady business.

• 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.
