The experimental design compared four cutting treatments: an uncut control (26\u00a0m<sup>2<\/sup>\u00b7ha<sup>\u22121<\/sup> of merchantable basal area [BA], with mean natural canopy gap areas of\u00a0\u2264\u00a0100\u00a0m<sup>2<\/sup> each) and three hybrid single-tree and group-selection cuttings corresponding to a light cut (20% removal; residual BA [RBA]: 21\u00a0m<sup>2<\/sup>\u00b7ha<sup>\u22121<\/sup&gt;; mean harvest gap area: 220\u00a0m<sup>2<\/sup>), a moderate cut (31% removal; RBA: 18\u00a0m<sup>2<\/sup>\u00b7ha<sup>\u22121<\/sup&gt;; gap area: 270\u00a0m<sup>2<\/sup>), and a heavy cut (42% removal; RBA: 15\u00a0m<sup>2<\/sup>\u00b7ha<sup>\u22121<\/sup&gt;; gap area: 340\u00a0m<sup>2<\/sup>). In the cuts, large-sized containerized seedlings of red spruce were planted within harvest gaps, while in the control, seedlings were planted systematically, for comparison. Three years later, a mechanical release treatment was applied in half of planted plots to limit competing vegetation. After eight years, seedling survival in the three cuts was equally high (&gt; 80%), and greater than in the control (40%). Morphophysiological performance of seedlings was best in the heavy cut creating the largest gaps. In general, the release treatment enhanced survival in the control and in the light cut with the smallest gap sizes. Release also improved morphophysiological performance (which, however, remained suboptimal) in all cutting treatments, but especially in the heavy cut. Although red spruce is highly shade-tolerant, the low survival and performance in the control suggest that for this species, seedlings grown with traditional forest nursery practices are not adapted to plantation under a closed canopy. Results indicate that enrichment planting in intermediate-size harvest gaps (of about 340\u00a0m<sup>2<\/sup> in area) of partially cut stands (of about 40% in BA) combined to mechanical release could be a good strategy to maintain or reintroduce red spruce and promote its morphophysiological performance.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Published in Forest Ecology and Management\u00a0478: 118514. https:\/\/doi.org\/10.1016\/j.foreco.2020.118514 In order to compensate for regeneration failure of red spruce (Picea rubens) in the managed temperate mixedwood forest, an enrichment planting study was conducted in yellow birch (Betula alleghaniensis)\u2013conifer stands, in Quebec, Canada.
