Grazing effects on biodiversity

Research on climate effects, especially related to climate change and extreme weather events in boreal and Arctic areas;
Experimental studies for providing baselines for modeling og on-going and future ecosystem change due to climate change;
Grazing ecology, especially related to effects of reindeer and goose;
Anthropogenic effects, especially changes in land use (e.g. afforestation, industry, reduced outfield grazing) and air pollution, plus indirect effects via climate change, as listed above;
Evaluations of biological diversity
Taxonomy and systematics, especially on some lichen genera
Impact assessments prior to planned land use changes.
