1. 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).

2. 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
3. Differences in deadwood quality and species diversity between production forests of different ages and nature reserves
Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologiSammanfattning : .... LÄS MER
4. Beetle Diversity – Land Sparing or Land Sharing? : the effects of timber extraction and restoration method on saproxylic beetle assemblages in mature managed pine forests
Kandidat-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : The impoverishment of saproxylic beetle communities is a growing concern for management of boreal forest biodiversity. Past research has found active restoration methods, such as creating deadwood and conducting prescribed burnings, to have a short-term positive effect on the species richness and compositional diversity of saproxylic beetle assemblages.

5. Differences and similarities in stand characteristics after prescribed burning and wildfire : implications for conservation of forest biodiversity
Master-uppsats, SLU/Dept. of EcologySammanfattning : 1. Wildfires are a natural disturbance in the boreal forests of Fennoscandia and have shaped and formed forests in the past, resulting in very heterogeneous forests containing large amounts of dead and living trees in various age classes.
