The research focuses on ecological processes in boreal forests and mountain regions. We try to understand how climate, topography, nitrogen deposition and different land use regimes, such as forestry and reindeer management influence these northern ecosystems. Central questions are how the organisms dispersal ability and species interactions influence ecosystem responses to a changing climate or increased nitrogen interactions. Research concerning how forestry influence biodiversity and ecosystem processes includes studies of mosses and epiphytic lichens, with a special focus on the position in the landscape, forestry regimes and dispersal ability of plants. The research concerning reindeer management includes studies in the mountains and the boreal forests. Effects of grazing on the vegetation and soils, interactions with other land users, such as forestry, and effects of a changing climate for the sustainability of reindeer management are a few central themes in this research.
