Conifer Regeneration After Experimental Shelterwood and Seed Tree Treatments in Broeal Forests - Finding Silvicultural Alternatives

This study aimed to identify viable silvicultural alternatives to conventional clearcutting for promoting successful forest renewal in black spruce stands across the eastern Canadian boreal zone. Researchers evaluated whether partial harvesting techniques, specifically variations of shelterwood and seed-tree cutting, could achieve adequate conifer density over a ten-year period. The results confirmed that these partial harvest methods, when implemented alongside mechanical site preparation such as spot scarification, successfully facilitated sufficient density of black spruce regeneration. The research supports the use of shelterwood and seed-tree systems combined with soil disturbance as effective management strategies for meeting sustainable forest productivity objectives.
