  1. 1. 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.

  2. 2. Mängden död ved i värdekärnor i Söderåsens nationalpark

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Gustav Thurell; [2024]
    Nyckelord :volym död ved; stående död ved; liggande död ved; bokskog; nedbrytningsgrad; värdekärna;

    Sammanfattning : There is a lack of knowledge about the development of the dead wood in former production beech (Fagus sylvatica) forests that have been protected. The present study has been carried out in Söderåsen National Park to compare the distribution of dead wood in relatively unaffected beech forests that have been protected for a long time (A-value cores) and older, previously managed beech forest that has only been protected for 20-30 years (B-value cores).

  3. 3. Utveckling av barrträdsföryngringar markberedda med grävmarkberedning kontra harvning på blockrik skogsmark

    Uppsats för yrkesexamina på avancerad nivå, SLU/Department of Forest Biomaterials and Technology (from 131204)

    Författare :Svante Brus; [2023]
    Nyckelord :markberedning; föryngring; död ved; tillväxt; ekonomi;

    Sammanfattning : Markberedning utförs på ungefär 90 % av den föryngrade arealen i Sverige varje år och utförs vanligtvis maskinellt med avsikt att bearbeta marken för att skapa goda förutsättningar för plantetablering. En icke obetydlig del av Stora Ensos markinnehav är på blockrik mark som är tekniskt svår att markbereda. LÄS MER

  4. 4. Differences and similarities in stand characteristics after prescribed burning and wildfire : implications for conservation of forest biodiversity

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Hannah Sophie Jakob; [2023]
    Nyckelord :coarse woody debris; conservation; biodiversity; boreal forest; Daldinia loculata; Fennoscandia; prescribed burning; regeneration; wildfire; woodpecker;

    Sammanfattning : 1. Wildfires are a natural disturbance in the boreal forests of Fennoscandia and have shaped and formed forests in the past, resulting in very heterogeneous forests containing large amounts of dead and living trees in various age classes. LÄS MER

  5. 5. Forest structure of Dalby Söderskog National Park : patterns of carbon storage in living and dead trees

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Kumetra Achuthan; [2021]
    Nyckelord :ash dieback disease; deadwood; Dutch elm disease; living tree volume; coarse woody debris; carbon stock and storage; pest invasions; temperate mixed broadleaved forest;

    Sammanfattning : Carbon sequestration and storage is an ecosystem service supplied by forests, and is of increasing importance in the context of mitigation of global climate change. Forest pest invasions, driven primarily by globalizations, represent a risk to the efficiency of carbon sequestration as they may greatly reduce the amount of the living biomass in forests. LÄS MER
