Polygalo majoris-Brachypodietum pinnati

These grasslands are usually dominated by Brachypodium pinnatum or Inula ensifolia and contain several continental species with their western distribution limit in southern Moravia, e.g. Campanula sibirica, Jurinea mollis, Polygala major and Pulsatilla grandis. They occur on south-facing slopes in dry colline landscapes of southern Moravia, mainly on moderately deep soils over calcareous flysch sediments. On some steep slopes affected by landslides, this vegetation may be considered as primary meadow steppe, but in most places it developed after deforestation of thermophilous oak or oak-hornbeam forests. Traditional management was the low-intensity grazing or occasional mowing. Today most sites are abandoned. At sites potentially supporting forests, shrubs and trees are slowly encroaching. In several places this dry grassland type has spread onto abandoned fields.
