Resum

The expansion of wild boar in Europe has also resulted in an increase in mountain areas, where it hasbeen observed above 2.000 m in summer. However, there is little information on habitat use and theimpact of wild boar in these ecosystems. IMPACTBOAR analyzed the seasonal use by wild boar of thedifferent habitats in the Parque Nacional de Aigüestortes i Estany de Sant Maurici, and its impact on:(1) plant communities of meadows, (2) recruitment of tree species, (3) demography of relevant rodentsfor seed dispersal (Apodemus spp.), and (4) predation of endangered species (e.g. capercaille, Tetrao urogallus). Results showed that wild boar presence in the Park has slightly declined in comparison to previous studies (2004-2005), being higher in spring and summer, lower in autumn and very scarce inwinter. Wild boar presence changes in the different habitats according to the season: i.e. it is higher inconiferous forests and meadows in summer; it increases in shrublands in spring and in deciduous forests during autumn. Wild boar activity is always higher in sites with southern exposure and areas withhigher diversity of land cover categories. The analysis of rootings indicated: i) large interannual variability in the amount of disturbed area (from 5 to 26%), ii) decrease in hemicryptophytes, increase in therophytes and slight decrease in geophytes, III) lower species richness, local diversity and differentiationof the vertical structure in rooting areas, but a higher overall diversity and, iii) no impact on the commonest species but trivialization of the flora, by an increase of cosmopolitan species. In contrast, theimpact on tree species and forest regneration was scarce. Also, wild boar activity did not affect the presence of rodents (dormice, voles and mice), which are usually distributed in areas not accessible (rockyareas), nor did we detect the consumption of capercaille.
