Researcher in various questions related to boreal forest biodiversity, specialty in deadwood depended beetles, including bark beetles.

Presentation

My research interests fall broadly on forest biodiversity, conservation and restoration. My main research questions have been how different forest restoration methods that resemble natural disturbances (forest fire, small-scale storm damage, gap-cutting), can enhance biodiversity in short- and long-term in boreal forest systems. To study short-term effects, I have used deadwood-dependent beetles and flat bugs, polypores, forest floor vegetation and tree stand structure as study objects. For long-term effects, we have used forest simulation tool MOTTI to predict the effects of the restoration methods on deadwood accumulation and tree species composition. Currently I work on questions related to measures of biodiversity, and on risks that active measures to restore forest biodiversity may cause to surrounding forest landscapes in the form of bark beetle invasions. In addition, I’m involved on projects of ecological offsetting and uneven-aged forestry.

Teaching

In 2017-2018 I give lectures on various courses in ecology and conservation biology. I am the course convener in Conservation Biology, 15 hp (MX0119).
