Background and activities
My main interest in conservation biology and ecology has been how anthropogenic processes affect biodiversity, ecosystem functions and services at different spatio-temporal scales.
My expertise is primarily within alpine, semi-natural and boreal (coniferous and deciduous forest) plant communities and ecosystems focusing on how land use processes in interaction with climate affects biodiversity components as well as supporting, regulating and provisioning services. I am also interested in the ecology of urban ecosystems and especially how the use of grasslands affects plant-pollinator interactions.
Experiences from interdisciplinary projects have provided insight in the science-policy interface and how e.g. socio-economic drivers indirectly affect nature and how people perceive and respond to these changes. Much of this interdisciplinary work has focused on the ecosystem impact of domestic livestock and wild ungulates but also how the management of large herbivore ecosystem engineers interacts with societal processes.
I teach several courses at Bachlor, Master and PhD level at NTNU. I have the main responsibility for the course «Sustainable Management of Ecosystem Services» (RFEL3082) (https://www.ntnu.edu/studies/courses/RFEL3082#tab=omEmnet at the Natural Resources Management Program https://www.ntnu.edu/studies/msnarm
