We assess the effect of natural disturbances and salvage logging on ants assemblages in the environment of mountain spruce forest within a disturbance gradient of in-tact forest – windthrow – bark beatle outbreak plots – clear cut. Using the pit-fall trap method we sampled 563 individuals of ants belonging to 8 different species. All recorded species belonged to characteristic forest species on mountain areas. We recorded significant dif-ferences both in species composition and species richness between clear-cut plots and intact forest together with windthrow. The species richness was about 3 times higher within the salvaged plots compared to other disturbance regimes. We also assessed the microhabitat structural characteristics of the different disturbance regimes. Clear cut plots were typical by increased proportion of grass species and increased proportion of characteristic forest herbs. Although the ant assemblages of clear cut habitats were di-verse and rich, we consider them of indicator of deforestation process, as a consequence of human intervention.
