Abstract

There were no significant differences in black spruce (Picea mariana [Mill.] B.S.P.) regeneration among strips 20, 40 and 80 m wide. Regeneration increased from marginally acceptable stocking levels (avg 53%) to desirable levels (avg 65%) during the third year of seeding. With only two years of seeding, scarified strips had better black spruce regeneration than non-scarified strips; after three years of seeding there were no differences between scarified and non-scarified strips. Scarification produces poorer regeneration in peaty drainageways than does non-scarification. Composition has changed from black spruce dominated in the pre-cut forest to a black spruce-white birth (Betula papyrifera Marsh.)-trembling aspen (Populus tremuloides Michx.) mixed-wood in the regenerated first-cut strips. Some silvicultural implications of these findings with respect to improvement of the alternate strip cutting system are discussed.
