The alliance Adenostylion alliariae includes subalpine vegetation of tall broad-leaved forbs and shrubby willows. It occupies wet habitats along mountain streams and in the glacial cirques where soil is well supplied with moisture fed by snowmelts. The soil has a high nutrient status. Adenostylion alliariae vegetation occurs in various mountain ranges of Europe. In the Czech Republic, it is most diverse in the Krkonoše and Hrubý Jeseník Mountains, but some communities are also found in other, lower mountain ranges, where they occasionally descend to the montane belt.
