  1. 6. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

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

    Författare :Rasmus Staaf; [2024]
    Nyckelord :artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

    Sammanfattning : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

  3. 7. Effect of stand age on soil respiration in managed vs unmanaged Scots pine stands

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

    Författare :Richard Engholm; [2024]
    Nyckelord :chronosequence; soil respiration; total respiration; autotrophic respiration; heterotrophic respiration; forestry;

    Sammanfattning : How the forests in Sweden and around the world have been, and are still today, managed is a hot debate. The rotation forestry that is commonly used in Sweden has been the focus of debate regarding whether it is a sustainable management method, and whether it should be changed. LÄS MER

  4. 8. 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

  5. 9. Learning a Grasp Prediction Model for Forestry Applications

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Elias Olofsson; [2024]
    Nyckelord :Forwarder; Autonomous grasping; Deep learning; Multibody dynamics; Convolutional neural network;

    Sammanfattning : Since the advent of machine learning and machine vision methods, progress has been made in tackling the long-standing research question of autonomous grasping of arbitrary objects using robotic end-effectors. Building on these efforts, we focus on a subset of the general grasping problem concerning the automation of a forwarder. LÄS MER

  7. 10. Orsaker till och åtgärder för att förbättra ekonomin i förstagallringar på Åland

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Robert Hellgren; [2024]
    Nyckelord :förstagallring; ekonomiskt utfall; Åland;

    Sammanfattning : Röjningsbehovet på Åland är stort och andelen eftersatta ungskogar ökar för varje år. Det ekonomiska utfallet i förstagallringar är väldigt dåligt och i många fall obetydlig, vilket gör att intresset för att röja är litet. Det leder många gånger till att ungskogarna röjs för sent och ibland uteblir röjningen helt. LÄS MER
