This grassland association is endemic to the glacial cirques of the Hrubý Jeseník Mountains. It occurs on avalanche tracks and sites with pronounced snow accumulation in the lower part of the cirques, on soils well supplied with water and nutrients. The stands are usually polydominant and consist of a rich mixture of grasses and tall forbs. Besides the Bupleuro longifoliae-Calamagrostietum arundinaceae, this is the species-richest community of natural grassland vegetation of the alpine and subalpine belts of the Czech mountains.
