The project supported efforts to protect an EU-wide endangered butterfly species, the Danube Clouded Yellow, in three Natura 2000 sites in Romania. The findings from the project can contribute to conserve the butterfly's population in other European countries, too. In order to provide access to this information also after the end of the project and beyond the region, a brochure and a short documentary film were produced in English, Romanian and Hungarian, and a poster was produced in English, German and Romanian. Scientific findings were published in specialist journals.
