  1. 1. Can the disappearance of the forest orchid Goodyera repens be linked to clearcutting? : a spatial analysis using citizen science data from southern Sweden.

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Ines Diaz Garcia; [2024]
    Nyckelord :Goodyera repens; knärot; Artportalen; forestry; clearcut; citizen science; southern Sweden; conservation;

    Sammanfattning : Habitat transformation through forestry has an impact on boreal species in northern Europe. In Sweden, even-aged plantations with clearcut harvesting are forestry practices that affect the understory vegetation. This study focuses on the red-listed Goodyera repens, a rhizomatous evergreen orchid. LÄS MER

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

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

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

    Sammanfattning : 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. LÄS MER

  4. 3. Are large clearcuts the only way to manage forests? : a study of economic performance and deadwood production of various silviculture systems

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Haidi Andersson; [2023]
    Nyckelord :uneven-aged forestry; continuous cover forestry; CCF; clearcut; deadwood; RFM; even-aged forest; Net present value; Heureka;

    Sammanfattning : Our forests are a natural resource which is needed for many purposes. Their importance and different values are expressed in the Swedish legislation, where production and environmental goals are set as equal. To many it is not sufficient, there has been a debate regarding how forests are managed and the practice of clear-cutting for decades. LÄS MER

  5. 4. Attitudes, existing support and required incentives to increase Continuous Cover Forestry in Sweden

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Victoria Lejon; [2023]
    Nyckelord :Continuous Cover Forestry; Conventional forestry; forest management; Sweden;

    Sammanfattning : An increasing wave of critique against conventional forestry favouring even-aged monoculture plantations and intense ground preparation in Sweden is arising, where some researchers are warning about the negative consequences of the long history of intense forestry and increasing extraction due to the growing demand for bioenergy has caused devastating consequences on ecosystems in forests such as loss of biodiversity. Additionally, reports are revealing that Sweden will not meet its own national environmental goals. LÄS MER

  7. 5. Omställning till hyggesfritt skogsbruk – föryngring i skog som ställts om från trakthyggesbruk till blädningsbruk

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Ida Pontén; Ludvig Renell; [2022]
    Nyckelord :plantetablering; omföring; markstörning;

    Sammanfattning : Skogsstyrelsen har fått uppdraget att öka kunskapen och användandet av hyggesfria metoder i det svenska skogsbruket. För att hyggesfri skogsskötsel ska kunna bli vanligare behöver skog som tidigare skötts med trakthyggesbruk istället börja skötas med hyggesfria metoder. LÄS MER
