Alliance ADE
Dryopterido filicis-maris-Athyrion distentifolii (Holub ex Sýkora et Štursa 1973) Jeník et al. 1980

Tall-fern vegetation of the alliance Dryopterido-Athyrion is confined to treeless talus slopes around the timberline. It is found in various mountain ranges of Europe and southern Siberia. In the Czech Republic, it occurs in the Krkonoše, Hrubý Jeseník, Králický Sněžník and Šumava Mountains, where most occurrences are confined to glacial cirques, in particular to leeward slopes with wet soils and distinct winter snow accumulation.
