Effectsof biomass harvest intensity and soil disturbance on jack pine stand productivity: 15-year results

Abstract: Rising demands for forest biomass have raised concerns that the increased removal of organic residues and harvest impacts may reduce longer term site productivity. Replicated field experiments examining the effects of stem-only harvest with disc trenching (SO T ), whole-tree harvest with (WT T ) and without (WT) disc trenching, whole-tree harvest with forest-floor removal by blading (WT B ), and blading followed by compaction (WT BC ) were installed on nine sandy jack pine (Pinus banksiana Lamb.) sites in nort… Show more

“…For example, the use of double-pass treatments (Thiffault et al 2005) or increasing disc angle to create larger furrows (Buitrago et al 2015) is expected to increase planted seedling growth, given that the treatments create larger areas free of the direct and indirect interferences of competing species, especially ericaceous species. Site preparation intensity, however, interacts with site characteristics; more severe treatments are not always followed by increased seedling growth (e.g., Fleming et al 2014). Also, responses to mechanical site preparation are routinely species-specific.…”

“…soil texture, humus thickness, dominant competing vegetation) can also lead to a limited effect of soil management intensity on planted seedling performance (e.g. Fleming et al 2014). In such contexts, managers can adapt prescriptions based on environmental, economic or social constraints, with limited (if any) impact on productivity (Barrette et al 2014).…”
