Évolution de la régénération après la coupe de peuplements récoltés selon différents procédés d'exploitation

摘要: Between 1982 and 1984, 289 sample plots were established on cutovers distributed across the mixed boreal forest zones of Quebec. Regeneration surveys before after clearcutting used to determine proportion regeneration destroyed by four different harvesting systems. Moreover, information evolution over medium term was gathered from realized five ten years following logging. For all stands combined, resulted in a reduction 25 40% stocking regeneration. The lowest decrease produced feller-forwarder that more efficient protect shorter than 50 cm as compared systems using cable skidders. Differences between no longer apparent first five-year-period logging because establishment new seedlings observed most sampled cutovers. ability balsam fir establish under canopy generally caused an incr...
