1. 1. 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

3. 2. Analys av föda för vitryggig hackspett och rödlistade vedlevande skalbaggar : utvärdering av tre olika behandlingar

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

   Författare :Emma Mattsson; Lena Ostermann; [2023]
   Nyckelord :Vitryggig hackspett; vedlevande skalbaggar; paraplyart; rödlista; biologisk mångfald; död ved; restaurering;

   Sammanfattning : Den vitryggiga hackspetten har sedan 1950-talet blivit en sällsynt art i det svenska landskapet. Nedgången beror främst på det moderna skogsbruket där barrskog till stor del har ersatt blandbestånd och gammal lövskog. LÄS MER

4. 3. The diversity of fungi in coniferous forests and mixed forests

   Master-uppsats, Karlstads universitet

   Författare :Ida Asplund; [2023]
   Nyckelord :Forest type; coniferous forest; mixed forest; fungi; fungal diversity; mycorrhiza; saprotrothic fungi; parasites; parasitic fungi; Skogstyp; barrskog; blandskog; svampar; svampdiversitet; svampmångfald; mykorrhiza; saprotrofiska svampar; parasiter; parasitiska svampar;

   Sammanfattning : The fungal domain has one of the highest biodiversities among eukaryotes and species within the domain fill important ecological roles, such as mutualistic mycorrhiza, decomposers, parasites and pathogens. The development of forest ecosystems and their related processes has not only been linked to fungal diversity but the composition and abundance of fungi benefits the abundance and diversity of other species as well.

5. 4. Managing diversity : the forest development types as a framework for management within mixed forest systems

   Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

   Författare :Pernilla Fridberg; [2023]
   Nyckelord :urban forestry; urban woodland; recreational forests; forest structure; vegetation structure; forest development types; mixed forest systems; forest management; close-to-nature management; Scanian forest systems; sustainable forest management; ecological values; resilience; sustainable cities; biodiversity; ; profile diagrams; conservation efforts; herbaceous mixed stands; species diversity; reference landscapes; forest communities;

   Sammanfattning : The demand for both biodiversity and recreational forests is increasing. Management methods under the umbrella term Close-to-Nature management, which aims to incorporate natural successional patterns and disturbances, is considered preferable to traditional forest management methods in terms of both recreational and ecological values (Wimberly et al.

7. 5. Effects of climate, soil, and forest structure on specific leaf area of understorey foundation plants

   Master-uppsats, SLU/Southern Swedish Forest Research Centre

   Författare :Sashank Khaniya; [2023]
   Nyckelord :Specific leaf area; understorey vegetation; foundation species; forest structure; climate change;

   Sammanfattning : Forest overstorey's interaction with understorey vegetation is a crucial aspect that impacts the biodiversity and resilience of forest ecosystems. Particularly, the influence of the overstorey on the specific leaf area (SLA) in understorey plants remains poorly understood. LÄS MER
