Restorati on of semi-natural grassland has been successfully realized on many diff ering sites for many years all over Europe. Restorati on success strongly depends on different factors: suitable site preparati on of receptor sites, selecti on of the opti mal restorati on method and target community, and the implementation of a proper management. Using seeds of regional provenance for the establishment of species-rich grasslands contributes to the enhancement of the biological diversity in the region. The developing species-rich grassland can fulfi l several ecosystem services such as water retenti on, carbon sequestrati on and oxygen producti on. In additi on, speciesrich grasslands are an important part of our cultural heritage, enriching the quality of life in the region.
