Carici bigelowii-Nardetum strictae (Zlatník 1928) Jeník 1961

new search

These grasslands occur in the Krkonoše Mountains, where they are mostly dominated by Nardus stricta, and in the Hrubý Jeseník Mountains, where Avenella flexuosa is usually the dominant species. A typical feature of this species-poor, acidophilous vegetation is the occurrence of Carex bigelowii and Festuca supina. It is a natural grassland occurring above the timberline where it occupies large areas. In the past it probably spread due to grazing and mowing on the summit plateaus and on slopes around the timberline. Due to abandonment and increased atmospheric nutrient deposition the stands of Nardus stricta are currently declining to the benefit of taller, more nutrient-demanding grasses.
