Harvesting Method Affects Survival of Black Spruce Advance Growth
Careful harvesting to preserve advance growth is an attractive regeneration option for many peatland black spruce stands. Success of this option depends on enough well-distributed trees surviving harvesting. This study examines the fate of black spruce advance growth following overstory harvesting by three methods. About 80% of the original advance growth stocking remained after winter harvesting, 70% after summer harvesting using wide-tired skidders, and 60% after summer harvesting using narrow-tired skidders. Mortality of advance growth occurred mainly during harvesting and in the first growing season after harvesting. North. J. Appl. For. 12(1):8-11.
