This species-poor community dominated by Nardus stricta occurs in the high mountain ranges, mostly at deforested sites below the timberline. It is confined to acidic, nutrient-poor soils, often on convex landforms. In the past these stands were occasionally mown but not fertilized. Vegetation change and forest succession after abandonment in secondary habitats is very slow. This vegetation type occurs in the Krkonoše, Orlické hory, Hrubý Jeseník and Šumava Mountains.
