  1. 1. Growth and quality of silver birch with different improvement levels

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Hanna Liebner; [2023]
    Nyckelord :Betula pendula Roth; genetic improvement; tree breeding; diameter growth; stem quality; branches quality;

    Sammanfattning : Silver birch is the most important broadleaf tree species in the context of wood production in Fennoscandia stating 12.9% of the total volume in Sweden (Nilsson et al., 2021). LÄS MER

  3. 2. Basal Area Growth and Yield Models for Siberian Larch

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Alfred Deutgen; [2023]
    Nyckelord :Growth model; Yield model; Siberian Larch; Russian larch; Larix sibirica; Larix sukaczewii; Lundqvist-korf model; Mixed effect model;

    Sammanfattning : There is no species-specific basal area growth model for Siberian Larch in Sweden, which is necessary in evaluating forest management decisions. Three different models were created from stand trials around Sweden. LÄS MER

  4. 3. Validation of basal area growth functions for larch in Heureka DSS

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Sebastian Carlzon; [2022]
    Nyckelord :validation; Heureka; Larix; Larix sibirica; Larix sukaczewii; Larix decidua; Larix x eurolepis; Siberian larch; European larch; hybrid larch; growth model validation; Heureka DSS; basal area growth;

    Sammanfattning : Larch is getting more common in Sweden. This highlights the need of reliable growth models for larch species in Heureka DSS. Precise and accurate growth models are essential for long-term forest planning. LÄS MER

  5. 4. Ståndortens påverkan på övre höjd : en jämförelse mellan tall (Pinus sylvestris) och contorta (Pinus contorta)

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Alfred Deutgen; Sixten Walheim; [2020]
    Nyckelord :Contorta; tall; höjdtillväxt; markfuktighet; översilning; jordtextur; övre höjd;

    Sammanfattning : En framtida befarad virkessvacka under 2000-talet gjorde att skogsbruket i Sverige började experimentera med främmande trädslag på 1960-talet. Målet var att öka produktionen med det snabbväxande trädslaget contortatall. Idag finns mer än 650 000 ha contortaskog på varierande marker i Norrland. LÄS MER

  7. 5. Thuja plicata : provenance experiments and cultivation trials in South Sweden

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Carolin Kemper; [2019]
    Nyckelord :Thuja plicata; Western red cedar; Provenances; Sweden; South Sweden;

    Sammanfattning : In times of climate change and an increasing number of threats for native tree species in Sweden and other countries in Europe, exotics as Thuja plicata (Donn ex D. Don) might be considered to a greater extent. LÄS MER
