This association includes open-canopy subalpine shrubberies dominated by Betula carpatica or Salix silesiaca, with a number of species typical of the herbaceous vegetation of Mulgedio-Aconitetea occurring in the herb layer. These shrubberies are found on avalanche tracks in the glacial cirques of the Krkonoše and Hrubý Jeseník Mountains, where they occupy marginal or terminal positions, only disturbed by less frequent, larger avalanches. Besides being disturbed by avalanches, woody plants in these places are affected by slow down-slope movement (creep) of the deeply packed snow.
