This type of species-rich subalpine tall-fern vegetation is dominated by Dryopteris filix-mas and contains both species of subalpine tall-forb vegetation and species of beech and ravine forests. It occurs on steep and well-insolated, partly soil-filled talus slopes in the glacial cirques of the Krkonoše, Hrubý Jeseník and Králický Sněžník Mountains. Winter snow cover is rather deep, ensuring frost protection for plants, however, it thaws quite early in spring due to slope steepness and direct exposure to the sun.
