  1. 1. 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

  3. 2. 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

  4. 3. Implementering av Skogliga Grunddata i hprGallring vid andragallring

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Felix Nilsson; Joakim Bengtsdahl; [2023]
    Nyckelord :gallring; uppföljning; laserskanning;

    Sammanfattning : Gallring är en av de skogsvårdsåtgärder som utförs i våra skogar för att bemöta de olika skogliga mål som skogsägarna har för sin skog. I Sveriges skogar så utförs gallringsåtgärder på ca 400 000 hektar årligen. LÄS MER

  5. 4. Water mapping in Scots pine stands after thinning

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Michalina Maria Grabowska; [2022]
    Nyckelord :Scots pine; Pinus sylvestris; drought; thinning; root system; water uptake; heavy water;

    Sammanfattning : Climate change is an ongoing issue in various fields, including forestry. More frequent and severe droughts have been already noted around the world, also in Europe. Visible reduction in available water in forests has adverse consequences such as increased tree mortality, higher vulnerability and smaller growth. LÄS MER

  7. 5. Forest damage in the eyes of scientists : framing damage perspectives in Swedish forestry

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Maria Jägerborg; [2022]
    Nyckelord :forest damage; frame analysis; discourses; scientists; qualitative interviews;

    Sammanfattning : Forest damage is a complex concept. Damaging agents appear naturally in ecological systems, but forest management also impacts their quantities. Damage can also be viewed from its interactions with a social system, where it appears and is understood. LÄS MER
