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

   University essay from SLU/Southern Swedish Forest Research Centre

   Author : Gustav Thurell; [2024]
   Keywords : volym död ved; stående död ved; liggande död ved; bokskog; nedbrytningsgrad; värdekärna;

   Abstract : 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. 2. Can precommercial thinning be used to create more diversity after planting spruce?

   University essay from SLU/Southern Swedish Forest Research Centre

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

   Abstract : 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. READ MORE

4. 3. Demographic equilibrium modelling of single tree selection stands in Siljansfors : judging the sustainability of single tree selection systems in Sweden

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Ludwig Olofsson; [2023]
   Keywords : CCF; continuous cover forestry; single tree selection; equilibrium models; forestry;

   Abstract : Lately debates have occurred questioning the rotation system, which is the most used silvicultural system in Sweden. Continuous cover forestry (CCF) has therefore been suggested as an alternative management method, due to its environmental benefits such as increased biodiversity and higher resilience against extreme weather which is important with the current climate change.

6. 5. Beståndsanpassad aptering: metodutveckling och utfallsprövning : effekter av varierande längdstyrning i egenskapsskilda beståndsgrupper

   University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

   Author : William Svederberg; [2023]
   Keywords : beståndsanpassad aptering; maskininlärning; produktionsstyrning;

   Abstract : Idag är tillgången till skogliga data mycket stor. En bidragande faktor till detta är insamlingen av data vid maskinell avverkning. Denna datamängd används i stor utsträckning för bland annat produktionsuppföljning men med viss bearbetning kan de användas för att digitalt återskapa den avverkade skogen. READ MORE
