Anne-Maarit Hekkala
Researcher, associate professor, in various questions related to boreal forest biodiversity, specialty in deadwood-depended beetles and fungi, and restoration and alternative forest management.


My research interests fall broadly on forest biodiversity, conservation and restoration of biodiversity in boreal forests. My main research questions have been how different forest restoration and alternative forest menagement methods that resemble natural disturbances (forest fire, small-scale storm damage, gap-cutting, uneven-age managemet), can affect biodiversity in short- and long-term in boreal forest systems. To study short-term effects, I have used deadwood-dependent beetles and flat bugs, primary bark beetles, pollinators, polypores, forest floor vegetation and tree stand structure as study objects. Currently I work on questions related to measures of biodiversity, how to best recognize forests stands that should be conserved and what are the best proxies of biodiversity. In addition, I study the networks of species dependent on deadwood and wild pollinators in my Formas-project, assess how Sveaskog's Ecoparks affect biodiversity of beetles and wild bees in the long term collaboration project with Sveakog and I’m involved on projects of ecological offsetting, short-rotation broadleaf tree management, uneven-aged forestry, to mention some exaples of the broadness of my research.


Course leader in the distance course Forest Animals, assistant course leader in the distance course Forest Conservation Biology. I teach in various courses in class, in the field and in recorded lectures about biodiversity, restoration, red-listing, and species recognition (indicator species, insects).
