These Sesleria caerulea dominated grasslands occur on steep slopes at low altitudes of northern and central Bohemia. The soils usually developed over Cretaceous marls, and are shallow, calcareous and strongly affected by erosion. Unlike the Sesleria grasslands of rock outcrops, this vegetation type contains several thermophilous species typical of deep, heavy soils. At some sites this is a natural vegetation on steep, erosion-prone slopes, from which this grassland may also spreads to adjacent, deforested and extensively grazed sites. Recent cessation of grazing in potential forest habitats has resulted in the spread of Brachypodium pinnatum at the expense of Sesleria caerulea and in a shift in species composition towards the association Scabioso ochroleucae-Brachypodietum pinnati.
