The ecosystems of the world are at present experiencing a rise in temperatures that will influence the structure of ecosystems. Alpine ecosystems are in particular exposed since they are characterized by low temperatures. As part of a larger European project, the flora on 4 summits in Dovre mountain region, Norway, was investigated in 2001. Some of the sampling areas were reanalysed in 2007. The results so far indicate an increase of shrubs, in particular Empetrum nigrum, at the lowermost summit, and a distinct decline of lichen cover, in particular Cetraria nivalis and Alectoria ochroleuca. Some new species have also arrived.
