  1. 1. Can precommercial thinning be used to create more diversity after planting spruce?

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Astrid Bygge; [2024]
    Keywords : Forestry; pre-commercial; stand structure; heterogeneity; silviculture; mixed forests; monoculture; Picea abies; Betula spp.;

    Abstract : Mixed forests will harbour other ecosystem services than a planted coniferous monoculture. This study used early results from a long-term experiment to examine if different precommercial thinning treatments can be used to increase diversity in planted stands of Norway spruce (Picea abies) mixed with high densities of natural regeneration of birch (Betula spp. READ MORE
