  1. 1. 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

  3. 2. Headfirst into shallow water - Wetland restoration and its contribution to the Habitats Directive

    Master-uppsats, Uppsala universitet/Växtekologi och evolution; Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Elin Brandt Korall; [2024]
    Nyckelord :Wetlands; GIS; Restoration; Rewetting; Ecology; LONA; Habitats Directive; Natura 2000; Nature conservation; Våtmarker; GIS; Geografiska informationssystem; Restaurering; Återvätning; LONA; Art- och Habitatsdirektivet; Natura 2000; Naturvård;

    Sammanfattning : Located in the borderland between aquatic and terrestrial environments, the wetlands cover a wide spectrum of habitats and enable living standards for a great variety of organisms. Although important habitats, a great extent of the original wetlands have disappeared in Europe and Sweden due to anthropogenic disturbances. LÄS MER

  4. 3. Vindkraftens påverkan på smålom

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

    Författare :Joel Hallingfors; Marcus Åsberg Genctürk; [2023]
    Nyckelord :smålom; vindkraftsetablering; skyddszon; buffertzoner; QGIS; habitatpåverkan;

    Sammanfattning : Vindkraftsetableringar i Sverige ökar och har ökat kraftigt de senaste åren. Etableringen leder till att olika intressen krockar med varandra och hänsyn måste tas till drabbade arter som exempelvis smålom (Gavia stellata). LÄS MER

  5. 4. Consequences of alternative forest management in riparian buffer zones : a GIS analysis

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

    Författare :Elijah Ourth; [2023]
    Nyckelord :Riparian buffer zones; Continuous cover forestry; CCF; Hyggesfritt; Geographical information system; Ditch network maintenance; Ditch; Stream; Natural channel;

    Sammanfattning : With increasing pressure from policymakers and the general public to conduct alternative forest management throughout the European Union (EU), Sweden needs to find ways to best prioritize the implementation of this alternative management. Alternative management is a term used to describe alternative management methods to clear-cut rotation forestry and can include silvicultural methods such as continuous cover forestry, management increasing proportion tree diversity and presence of broadleaves, and extended rotation lengths.

  7. 5. GIS and remote sensing based mapping of microtopography and vegetation composition in a boreal mire complex

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

    Författare :Nils Helge Havertz; [2023]
    Nyckelord :Microtopography modelling; Remote sensing; Boreal mixed mires; Object Based Image Analysis OBIA ; random forest RF ;

    Sammanfattning : Small scale variations in mire surface elevation referred to as microtopography are fundamental characteristics of mire ecosystems especially in the boreal region. Microtopography commonly classified into hummocks and hollows play a major role in several ecological, hydrological and biogeochemical processes including vegetation composition and carbon and methane dynamics.
