Résumé

Regeneration was studied 5 years after harvesting on 128 permanent blocks located before logging in black spruce (Picea mariana (Mill.) BSP) stands. Regeneration after 5 years was related to the abundance of advance growth, mainly black spruce layers. Regeneration also differed with the harvesting system used. Best results were obtained with the use of feller-forwarders while tree-length harversting gave the lowest softwood stockings. Regional climax and soit texture also had an effect, mostly by modifying the advance growth abundance. The better softwood stocking observed on thick humus and in the black spruce - moss climax zone was related to higher precutting regeneration levels. The regeneration problems observed on coarse textured soils were also associated with initial differences in the amount of advance growth. The duration of spruce budworm (Choristoneura fumiferana (Clem.)) infestations seemed to have an impact on the regeneration of the stands studied. Hardwoods regeneration, mostly white birch (Betula papyrifera (Marsh.)), became established after logging or after defoliation by the spruce budworm. Their abundance was also dependent on regional climax and soil texture.
