  1. 1. Kulturreservatet Gunnebos öppna diken - en undersökning med avstamp i kulturhistorisk värdering och biologisk mångfald

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Mia Maria Nilsson; [2024-01-09]
    Nyckelord :ditches; cultural heritage; biodiversity;

    Sammanfattning : This essay was written with the knowledge that Gunnebo’s landscape management plan is in need of revision, mainly to adapt its maintenance to new research and updated national environmental goals. The cultural reserve’s ditches are mentioned in passing in the care plan but there is no overall or collective documentation of the ditches structure or origin. LÄS MER

  3. 2. 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.

  4. 3. 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.

  5. 4. Vilka naturvärden går att finna i nyligen återställda våtmarker i skogslandskap baserat på förekomsten av insekter?

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Sammanfattning : Svenska våtmarker har under flera hundra år dikats ut till förmån för odling av grödor och virkesproduktion. Idag ser verkligheten annorlunda ut och till förmån för klimatet satsar svenska staten nu pengar på att plugga igen diken och återställa dessa numera uttorkade våtmarker. LÄS MER
