These are species-poor subalpine grasslands dominated by Molinia caerulea, containing some moisture-demanding species, such as those of the genus Sphagnum. In places a thin peat layer may accumulate. The stands of this community usually occur on upper leeward slopes in glacial cirques with a massive winter snow pack and abundant spring moisture during thaw. They occur in the Krkonoše Mountains; rare and fragmentary stands have also been recorded in the Hrubý Jeseník Mountains.
