  1. 1. Effects on natural seed regenerated Silver birch (Betula pendula Roth) and Downey birch (Betula pubescens Ehrh) by mechanical soil scarification and environmental factors : påverkan på naturligt fröföryngrad Glasbjörk (Betula pubescens Ehrh) och Hängbjörk (Betula pendula Roth) av mekanisk markberedning och omgivande faktorer

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

    Författare :Oskar Karlsson; [2022]
    Nyckelord :natural birch regeneration; Birch seed regeneration; soil scarification;

    Sammanfattning : The awareness of forest biodiversity as well as the demand for a higher proportion of deciduous tree species in Swedish forests increases. As such, focus is shifting towards the management of naturally seed regenerated Silver birch (Betula pendula Roth) and Downey birch (Betula pubescens Ehrh). LÄS MER

  3. 2. Restoration of mixed forest : effects of fencing, site preparation and distance to existing mixed forest on planted European beech and natural tree regeneration

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Mateusz Szydło; [2017]
    Nyckelord :European beech; fencing; mixed forest restoration; mechanical site preparation; Scots pine; Raslången ecopark;

    Sammanfattning : During restoration of mixed forest from mono-specific spruce forest there is a great need for knowledge of the extent to which proximity to other mixed forest affects regeneration results and diversity of tree and shrub layers. There is also lack of knowledge of what fencing means for the regeneration of individual species, as well as how mechanical site preparation (MSP) influences both planted and naturally regenerated plants.

  4. 3. Högskärmar och kalhyggesfritt skogsbruk på bördig mark i Medelpad

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

    Författare :Elsa Järvholm; [2011]
    Nyckelord :högskärm; gran; föryngring; skador; kontinuitetsskogsbruk;

    Sammanfattning : Under senare år har intresset för ett alternativ till kalhyggesbruk vuxit sig starkare i både Sverige och andra länder i Europa. I Sverige ses skärmskogsbruk och blädning i granskogar som två högst intressanta alternativ till kalhyggesbruk. 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
