Alternative Silvicultural Systems on Steep-Sloped Old-Growth Forests on the Queen Charlotte Islands Project Overview and Regeneration Development

This case study details a research project investigating alternative silvicultural systems to clearcutting in the steep-sloped old-growth forests of the Queen Charlotte Islands (now Haida Gwaii). The study, initiated in 1992, compared the effects of single-tree selection, two levels of group selection, and clearcutting on regeneration (both natural and planted) and residual stand characteristics over a seven-year period. Key findings address the effectiveness of these methods in promoting the regeneration of western hemlock, Sitka spruce, and western redcedar, as well as the impact on residual tree damage and browsing pressure from Sitka black-tailed deer, ultimately aiming to inform sustainable forest management practices in this sensitive ecosystem.
