Three expert teams carried out inventory/mapping of butterflies in the 10 Natura 2000 sites. This involved 37 transects, each surveyed during 3 different periods, in order to identify species with varying flight times. The recorded number of butterflies in the project areas has nearly doubled, increasing from 49 to 97. Maps and inventories were created for the protected butterfly species Colias myrmidone and Leptidea morsei. Species diversity and population abundance of Lepidoptera is significantly higher in a traditional haymeadow compared with pasture.
