However, on some boreal sites characterized by a thick humus layer and dominated by ericaceous shrubs, competition seems to limit the benefits of scarification. A potential solution would be to remove OM completely through scalping. The objective of our study was to compare the short-term effects of scarification and scalping on the growth of <em>Picea mariana<\/em> and <em>Pinus banksiana<\/em> on such sites. After three growing seasons, we explored the relationships between seedling growth, groups of competing vegetation species, planting depth and distance to the nearest OM accumulation. The two treatments had similar effects on these variables. Growth on plots subjected to scalping was independent from the distance to OM. Planting depth had a nil or positive effect on seedling growth. <em>Pinus <\/em>seedlings largely outgrew <em>Picea <\/em>seedlings. However, the lack of short-term difference between scarification and scalping must be interpreted with caution, given the potential mid- and long-term effects of OM exportation on soil fertility, erosion and seedling nutrition.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Published in The Forestry Chronicle 92(2): 221-231. https:\/\/doi.org\/10.5558\/tfc2016-041 Scarification contributes to creating planting microsites for reforestation by mixing organic matter (OM) with the upper layers of mineral soil.
