The technical staff and facilities based in Kolari support ecological research in northern Finland, focusing on north boreal forests and peatlands as well as on fish populations in the Tornionjoki river system. ICP Forests Level II site in Pallasjärvi and many other Luke’s long-term forest and peatland experiments, including managed and semi-natural reference areas (trials on tree breeding and progeny, fertilization, northern timberline forests) are largely maintained from Kolari. Research carried out on nature-based tourism is also supported.
