Decline of rare and specialist species across multiple taxonomic groups after grassland intensification and abandonment

摘要: Traditionally managed mountain grasslands are declining as a result of abandonment or intensification management. Based on common chronosequence approach we investigated species compositions 16 taxonomic groups traditionally dry pastures, fertilized and irrigated hay meadows, abandoned (larch forests). We included faunal above- below-ground biodiversity well traits (mainly rarity habitat specificity) in our analyses. The larch forests showed the highest number (345 species), with slightly less pastures (290 species) much meadows (163 species). proportion rare was lowest meadows. Similar patterns were found for specialist species, i.e. high specificity. After abandonment, harbor higher pasture than These overall trends mainly supported by spiders vascular plants. Lichens, bryophytes carabid beetles partly contrasting trends. findings stress importance to include wide range conservation studies. All all, both had similar negative impacts study, underlining value Inner-Alpine pastures.
