The alliance Nardo-Agrostion includes grasslands of Nardus stricta which develop at deforested sites of the montane belt in the high mountain ranges which possess a well-defined alpine belt. The stands of the Nardo-Agrostion contain a mixture of species from different altitudinal belts, including both the alpine and submontane grassland species pools. This alliance is distributed in the Carpathians and probably also in the Alps. In the Czech Republic, well developed stands occur only in the Krkonoše Mountains.
