This association of open Corynephorus canescens grasslands is typical of acidic sand dunes. Most of these dunes originated in places of large-scale disturbances such as forest clearings, pastures, sand pits or on military training grounds. Recurrent disturbance at an interval of every few years is necessary for this vegetation type to persist and to prevent succession towards closed grassland. Most localities are found on the terraces of the Labe river, in sandstone-dominated areas of northern Bohemia, and near Hodonín in southern Moravia.
