The paper deals with succession course on disturbed habitats in mountains of Murmansk province. Among the most successful invaders on small-scale disturbances of dry and mesic sites are reported differential species of associations Luzuletum arcuatae, Juncetum trifidi and Cetrarietum nivalis which belong to Alliances Salicion herbaceae, Saxifrago stellaris-Oxyrion digynae, Loiseleurio-Diapension, on mesic and fresh sites - differential species of Alliance.
