The Podyjí NP has very diverse vegetation which results in the occurrence of rich butterfly communities. To date, 142 species of butterflies have been recordeed in this area, of which 19 species (13 %) are considered regionally extinct and three species (2 %) are only migrants, not native to the Czech fauna. The main cause of the decline in butterflies is the abandonment of traditional techniques of habitat management. To conserve and support butterfly diversity, the NP authority practices a wide range of management measures. and Milan Švestka.
