Black spruce reforestation in Kalmia heath: seedling response to forest floor mixing and mycorrhizal inoculation with Paxillus involutus
In the boreal forests of eastern Canada, black spruce ( Picea mariana (Mill.) Britton, Sterns, Poggenb.) regeneration often fails in nutrient-poor sites dominated by Kalmia angustifolia L. occurring after nonsevere forest fire, clearcut harvesting, and insect defoliation. Traditional silvicultural t...
