1. Effect of stand age on soil respiration in managed vs unmanaged Scots pine stands
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : How the forests in Sweden and around the world have been, and are still today, managed is a hot debate. The rotation forestry that is commonly used in Sweden has been the focus of debate regarding whether it is a sustainable management method, and whether it should be changed. LÄS MER
2. Mängden död ved i värdekärnor i Söderåsens nationalpark
Master-uppsats, SLU/Southern Swedish Forest Research CentreSammanfattning : 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. Are large clearcuts the only way to manage forests? : a study of economic performance and deadwood production of various silviculture systems
Master-uppsats, SLU/Southern Swedish Forest Research CentreSammanfattning : Our forests are a natural resource which is needed for many purposes. Their importance and different values are expressed in the Swedish legislation, where production and environmental goals are set as equal. To many it is not sufficient, there has been a debate regarding how forests are managed and the practice of clear-cutting for decades. LÄS MER
4. Analys av föda för vitryggig hackspett och rödlistade vedlevande skalbaggar : utvärdering av tre olika behandlingar
Kandidat-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : 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
5. Demographic equilibrium modelling of single tree selection stands in Siljansfors : judging the sustainability of single tree selection systems in Sweden
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : 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.
