This dry grassland is dominated by the tussock-forming grasses such as Avenula pratensis and Festuca ovina. It supports several generalists of dry, sandy grasslands. Mosses and lichens are also common. It occurs on gentle slopes with shallow acidic soils over granite, gneiss, shale or basalt, rarely also over sandstone or sand. It is a secondary vegetation type at formerly forested sites. Traditionally it was used for low-intensity grazing, but currently most sites have been abandoned, and subsequently invaded by Arrhenatherum elatius. The association is relatively common on the south-eastern fringes of the Bohemian Massif, but some scattered localities are also found in northern and central Bohemia.
