    Nyckelord :single-tree stem volume; stem diameter;

    Sammanfattning : The aim of this study was to evaluate different types of volume and taper equations that can be used to predict single-tree stem volume and stem diameter at any given height along the tree stem for plantation grown Sitka spruce (Picea sitchensis (Bong.) Carr.), Norway spruce (Picea abies (L. LÄS MER

  3. 2. Produktivitetseffekter av flerträdshantering

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Andreas Rönnqvist; [2011]
    Nyckelord :Gallring; Flerträd; Skördare;

    Sammanfattning : The main purpose of this study is to investigate the productivity effects of multiple tree handling in thinnings. Other important elements have been to investigate in which extent multi-tree handling is used in stands with different stem volumes and the impact of collecting partially delimbed fuelwood assortments has on harvesting performance.

    Sammanfattning : I Sverige är trakthyggesbruk med kalhuggning det dominerande skötselsystemetmen intresset för kalhyggesfritt skogsbruk har ökat de senaste åren. Alternativentill kalavverkning är omdiskuterade och kritiseras ofta för att inte vara lönsamma. LÄS MER

  5. 4. Vegetation succession and biomass production after peat ash and PK-fertilization on the cutaway peatland of Näsmyran in Hälsingland, Sweden

    L3-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Stefanie Leupold; [2005]
    Nyckelord :biomass production; afforestation; cutaway peatlands; fertilization; vegetation succession;

    Sammanfattning : By 2010, the total area of cutaway peatlands ready for after use in Sweden is expected to be 3 000 – 5 000 ha. Afforestation of terminated peat cuttings is one of the most favoured after use options and can be suitable for commercial timber production if drainage and nutrition status are taken care of. LÄS MER
