This vegetation type is dominated by the tussock-forming grass Deschampsia cespitosa and contains some tall forbs and the grass Poa chaixii. It occurs in the subalpine belt of the Hrubý Jeseník and Králický Sněžník Mountains on gentle slopes, plateaus or in shallow and flat depressions, where soil is well supplied with moisture, e.g., near springs or in places with deep snow pack. Some stands are natural, but others developed as a result of human activities. Species-poor stands of Deschampsia cespitosa, physiognomically similar to this association, are currently spreading in abandoned meadows and pastures of the Krkonoše Mountains.
