  1. 1. 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

  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. Granbarkborreangrepp i och kring naturreservat : hur påverkar åtgärder?

  5. 4. Effects of management and plant traits on tree-related microhabitats in second-growth stands of the Białowieża Forest

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Weronika Mysiak; [2022]
    Nyckelord :tree-related microhabitats; TreMs; Białowieża Forest; post-Century stands; second-growth forest;

    Sammanfattning : The study presents research conducted on Tree-related Microhabitats (TreM) in managed stands and nearly unmanaged stands in the Białowieża Forest (BF). A TreM is an above-ground structure that creates substrate, site or place for forest-dwelling species, and could be an important tool for assessing the level of biodiversity. LÄS MER

  7. 5. Impact of forest management on the diversity of wood decaying fungi : A comparison between two closely related forests in southern Sweden

    Kandidat-uppsats, Linköpings universitet/Biologi

    Författare :Johanna Sollén Mattsson; [2022]
    Nyckelord :Biodiversity; Boreal forests; Forest management; Forestry; Natural forests; Wood decaying fungi;

    Sammanfattning : Modern forestry practices have negative effects on many organisms because they change the forest’s disturbance dynamics, makes the forest’s structure less complex, and fragments old-growth forests. This study examined how commercial forestry practices affect the diversity of wood-decaying fungi, by comparing two closely related forests with different management in Östergötland, Sweden. LÄS MER
