    Abstract : The Swedish boreal forests have changed drastically in the last century. Intensive forestry with clear-cuttings and fire-prevention, cause a lack in dead wood diversity and volume. The current research on forests mainly focuses on productive forests and there is a knowledge gap regarding the importance of low-productive forest for biodiversity. READ MORE

    Abstract : Lately debates have occurred questioning the rotation system, which is the most used silvicultural system in Sweden.
