My research has two main themes: stand dynamics of uneven-aged forests, and incorporating biomechanics in studies of tree growth
In teaching I am involved in almost all courses in silviculture at the department, at all levels at the Jägmästarutbildning (MSc in Forestry).
My main responsibility in teaching is silviculture in general and especially growth and yield. I teach Silviculture at all levels in the Jägmästarprogrammet (MSC in Forestry). As part of this work I have co-authored three chapters in Skogsskötselserien på internet. I also supervise students doing their Bachelor and Master Thesis.‘
Uneven-aged silviculture and single-tree selection
Most of the work deal with Picea abies forests. It is based on permanent field experiments, established in 1990-91, repeated surveys and reconstructions. Analyzes have focused on volume increment, changes in the stand structure and ingrowth.
There has also been a recent study in uneven-aged Pinus sylvestris forests.
Tree growth and biomechanics
The work is focused on the biomechanical theory of tree growth, which states that radial growth of tree stems is mainly a result of mechanical stress, caused by wind sway. The long term goal is to incorporate the theory in a new generation of growth models.
