Régénération dans les sentiers de débardage en pessière noire irrégulière du Québec
|Advisor:||Ruel, Jean-Claude; Bégin, Jean|
|Abstract:||Regeneration in logging trails following irregular shelterwood cutting was assessed in Quebec’s boreal forest. In each of five sites, a regeneration inventory was carried out and study plots were installed for this evaluation. Two years after harvest, average regeneration density and stocking in logging trails were 10 780 stems•ha-1 and 77%, respectively. Regeneration density was negatively affected by increasing slash cover across all study sites. Seedling establishment was influenced by direct seeding, position within the logging trail, and substrate type. Environmental conditions were adequate: light availability was sufficient and severe soil compaction was limited. Direct seeding was not very effective on these sites, but the planted black spruce stock responded well. Results suggest that regeneration in logging trails was abundant and well distributed in the first two years after harvest.|
