Describing Old Growth Forests in the Boreal Foothills Natural Disturbance Unit
This report examines how to define and identify old-growth forests in the Boreal Foothills of British Columbia, emphasizing that age alone is an insufficient measure.

It introduces an index of old-growthness, a quantitative scoring system based on multiple structural attributes like tree and snag diameters, coarse woody debris volume, and the presence of specific wildlife habitat features. The study aims to move beyond simple age-based classifications, providing forest managers with a more biologically meaningful tool to assess and conserve these vital ecosystems, acknowledging that structural characteristics, rather than just age, are the true indicators of an old-growth forest's ecological value. -
Recent Crown Thinning in a Boreal Black Spruce Forest Does Not Reduce Spread Rate nor Total Fuel Consumption - Results from an Experimental Crown Fire in Alberta, Canada
This paper details an experimental crown fire conducted in an Alberta, Canada, boreal black spruce forest to assess the effectiveness of recent crown thinning as a fuel treatment. Researchers ignited a 3. 6-hectare fire, observing its behavior in bot...This paper details an experimental crown fire conducted in an Alberta, Canada, boreal black spruce forest to assess the effectiveness of recent crown thinning as a fuel treatment. Researchers ignited a 3. 6-hectare fire, observing its behavior in both untreated and thinned sections. The key finding was that while thinning led to a significant reduction in fire intensity, it did not reduce the fire's spread rate nor total fuel consumption. This suggests that in dense boreal black spruce with high surface fuel loads and low crown base heights, thinning alone may not prevent the rapid progression of crown fires, but it could potentially aid suppression efforts by reducing the intensity. -
