  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.

  3. 2. Marktäckets och markfuktighetens påverkan på blomsterlupinens (Lupinus polyphyllus) utbredning i Jämtland

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Julia Svedh; [2024]
    Nyckelord :Garden lupine; Lupinus polyphyllus; soil moisture; land cover; invasive alien species; Jämtland; ; Blomsterlupin; Lupinus polyphyllus; marktäcke; markfuktighet; invasiva främmande arter; Jämtland;

    Sammanfattning : Biodiversity is the prerequisite for well-functioning ecosystem services that are crucial, like clean water and clean air. Invasive alien species (IAS) are a serious and long-term issue that is actively threatening the genetic diversity within ecosystems. LÄS MER

  4. 3. Can precommercial thinning be used to create more diversity after planting spruce?

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Astrid Bygge; [2024]
    Nyckelord :Forestry; pre-commercial; stand structure; heterogeneity; silviculture; mixed forests; monoculture; Picea abies; Betula spp.;

    Sammanfattning : Mixed forests will harbour other ecosystem services than a planted coniferous monoculture. This study used early results from a long-term experiment to examine if different precommercial thinning treatments can be used to increase diversity in planted stands of Norway spruce (Picea abies) mixed with high densities of natural regeneration of birch (Betula spp. LÄS MER

  5. 4. 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

  7. 5. 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.
