AbstractThe study aimed to test the effect of a long term and short term grazing on the structure of Curculionoidea assemblages on extensively managed mountain meadows in the Gorce National Park (Western Carpathians, Poland). Researches were conducted in 7 types of plant communities, each in a different stage of the succession: from pastures used every year to the communities with dominating Vaccinium myrtillus unmanaged for several years. Analysis of variance revealed that long term abandoned pastures impoverishes species diversity of weevils. Traditional grazing activity didn’t have any significant effect on the differentiation of assemblages and their structure parameters. Multi-dimensional scaling showed important differences in the species composition of weevil assemblages in early and late stages of the plant succession. Annual extensive grazing should be an important tool for maintaining of the herbivorous beetles assemblages. This procedure turned out to be the effective way of the active protection on seminatural open areas in the Gorce National Park.
