  1. 21. The wood-inhabiting fungal community on standing dead birches : a comparison of ring-barked and naturally dead trees

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Samuel Persson; [2022]
    Nyckelord :Wood-inhabiting fungi; ring-barking; community ecology;

    Sammanfattning : Dead wood is an important part of forest ecosystems, especially since so many organisms depend on it for nutrients or as substrate for breeding or foraging. Since forestry intensified in northern Europe during the mid 1900s, the amount of dead wood in Fennoscandian forests has drastically decreased. LÄS MER

  2. 22. Restaureringens effekt på öringpopulationen

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

    Författare :Ola Carlström; Sebastian Dagman; [2022]
    Nyckelord :restaurering; flottning; öring; älv; bäck;

    Sammanfattning : Until the 1970s, rivers in Sweden were used for timber floating. In order for the floating to be as efficient as possible, with a minimum of timber getting stuck, many rivers were cleared. Large rocks and boulders were removed from the main channel and tributaries, backwaters and shallow areas were secluded. LÄS MER

  3. 23. Insektsamhällen i restaurerade skogar : en studie på hur abundansen av insektordningarna skalbaggar (Coleoptera), tvåvingar (Diptera), steklar (Hymenoptera) och fjärilar (Lepidoptera) ser ut i luckhuggna och brända bestånd jämfört med kontrollskogar

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

    Författare :William Arnvik; Emil Gustavsson; [2022]
    Nyckelord :Naturvårdsbränning; Luckhuggning; Skogsrestaurering; Boreal skog; Död ved; Naturvård;

    Sammanfattning : Den biologiska mångfalden i de boreala skogarna har minskat. Det finns flera orsaker till detta, varav ett är trakthyggesbruket. På grund av trakthyggesbruk har dynamiken och strukturen i skogarna förändrats och strukturen till ett onaturligt tillstånd. Det skapas inte mycket gammal skog p. LÄS MER

  4. 24. Alteration of the forest structure in historically impacted Nothofagus spp. forests on the Brunswick peninsula : recommendations for their protection and management

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

    Författare :Leon Hauenschild; [2022]
    Nyckelord :Nothofagus spp. forests; Brunswick peninsula; Forest history; Indigenous land use; Holistic conservation;

    Sammanfattning : Despite exhibiting a seemingly low degree of human alteration when compared to other types of landscapes, most forest ecosystems in the world have a long history of human use and are prod-uct thereof. The southern Brunswick peninsula is no exception to this and has an extensive history of anthropogenic activity, both pre-colonial and modern. LÄS MER

  5. 25. Ekologiska restaureringsåtgärders påverkan på unga trädplantor : bränning och luckhuggnings effekt på unga trädplantor

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

    Författare :Atle Brevik Svensson; Ludwig Olofsson; [2022]
    Nyckelord :biodiversitet; bränning; luckhuggning; ekologisk restaurering; skogsbruk; störning; succession; trädslagsblandning; unga trädplantor;

    Sammanfattning : Biodiversity is fundamental for a stable and functional ecosystem. However, studies have shown that biodiversity in Sweden is slowly declining due to modern forestry. This needs to be changed and ecological restoration can prevent further biodiversity loss. LÄS MER
