Adenostylo-Pinetum mugo is a rare community of Pinus mugo scrub with subalpine tall forbs such as Athyrium distentifolium, Cicerbita alpina, Gentiana asclepiadea, Rumex arifolius, Senecio hercynicus and Veratrumalbum subsp. lobelianum. It is found on avalanche tracks and on leeward slopes of glacial cirques in the Krkonoše Mountains at altitudes of 1100–1300 m. These sites are characterized by a deep snowpack in winter, moist soil in spring and summer, and fast litter decomposition, which prevents accumulation of the thick raw humus typical of the previous association of Pinus mugo scrub. Only small patches of this vegetation are known from the Krkonoše.
