These species-poor grasslands of Juncus squarrosus and Nardus stricta occur in shallow wet depressions or on the edges of mires. The soils are wet, acidic and poor in nutrients. Such conditions support development of a rich moss layer and at some sites they are also conducive to processes of peat formation. The community is found in precipitation-rich areas of the Czech Republic and it is most common in northern and north-western Bohemia. It also occurs in the Třeboň basin of southern Bohemia and elsewhere in the mountains.
