Location: Western Quebec
Research Type: Radiocollar study
Forest Type: Black spruce, balsam fir, white birch, trembling aspen

Coarse woody debris (CWD): "The most important structural elements for marten habitat in winter are coarse woody debris and coniferous saplings." In mature black spruce stands, CWD was lower in older stands, thus no structural advantage to mature black spruce forests, opposed to western North America. Dense coniferous cover not required; more structure dependent.

Clearcuts: Martens in this study were "intolerant of habitat fragmentation and cannot tolerate more than 30-35% cutovers in its home range"

Management Recommendations: Greater than 50% uncut forest should be preserved inside 10 km2 units and less than 30% of area should be clearcut over a 30 year period. "Uncut forest patches should be large (>100 ha) to maximize core area and minimize edge with open cutovers.
