R18 Perennial rocky calcareous grassland of subatlantic-submediterranean Europe
Open grassland dominated by perennials and especially rich in mat-formers, typical of rudimentary, shallow, nutrient-poor, base-rich soils over sloping, rubbly limestone terrain. It occurs in the lowland to submontane belts in subatlantic and submediterranean Western Europe, including some areas at higher altitudes in the Western Mediterranean mountains, which were traditionally maintained by extensive grazing.
