Kivonat:

Continental semi-dry grasslands replaced here the xerothermic oak forests (Corno-Quercetum pubescentispetraeae) and dry oak-hornbeam forests (Waldsteinio-Carpinetum = Querco-Carpinetum waldsteinietosum). They were originally rich in forest-steppe elements due to the edaphic conditions. The semi-natural steppelike grasslands were stabilised by the traditional use. They were abandoned in the sixties-seventies. Thus, the cover of polycormon-forming and tall-forb species, typical for the forest-skirts, has increased ("Versaumung"). The edaphic conditions (calcareous substrate, often covered by "terra rossa") are rather suitable for developing of the semi-dry grasslands, rich in species. They belong to the alliance Cirsio pannonicae-Brachypodion pinnati. Main groups of characteristic and dominant plant species are as follows.

  • Character species of the alliance Cirsio-Brachypodion and local character species of semi-dry grasslands: Cirsium pannonicum, Polygala maior and Danthonia alpina, Alyssum montanum ssp. brymii, resp.
  • Festucion valesiacae steppe grassland (and loess grassland!) species: Adonis vernalis, Aster linosyris, Dianthus pontederae, Echium maculatum, Nonnea pulla, Phlomis tuberosa, Pulsatilla grandis, Stipa joannis.
  • Character species of dolomit grasslands (Stipo pulcherrimae-Festucetalia pallentis): Poa badensis, Anacamptis pyramidalis, Arenaria micradena, Cytisus procumbens, Globularia punctata, Iris pumila.
  • Species of xerothermic forest-skirts ("Trifolio-Geranietea"): Anemone sylvestris, Cytisus albus, C. hirsutus ssp. leucotrichus, Dorycnium germanicum, Geranium sanguineum, Inula hirta, I. salicina, Lathyrus latifolius, Libanotis pyrenaica, Peucedanum cervaria, Teucrium chamaedrys, Thymus kosteleckyanus, Trifolium alpestre, Veronica austriaca ssp. teucrium.
  • Festuco-Brometea species of high cover in Cirsio-Brachypodion: Aster amellus, Centaurea triumfetti, Campanula sibirica, Centaurea scabiosa, C. spinulosa, Hypochoeris maculata, Inula ensifolia, Jurinea mollis, Lathyrus pannonicus, Linum flavum, L. hirsutum, L. tenuifolium, Scorzonera purpurea, Thesium linophyllon.
  • Festuco-Brometea species of high cover in traditionally managed grasslands: Anthyllis vulnararia, Coronilla varia, Onobrychis viciaefolia, Rhinanthus minor, Salvia pratensis, Trifolium montanum, Vicia tenuifolia.
  • Rare biogeographical components of high conservation value: Pulsatilla halleri ssp. slavica, P. patens (only at the Slovakian side), Dracocephalum austriacum,

Our relevés can be grouped into the following associations:

  1. Polygalo (maiori) - Brachypodietum pinnati WAGNER: tall-grass sward with many species of forbs, dominant grassland type of the mesophilous sites of dolinas on the higher plateaus.
  2. Hypochoeri - Brachypodietum pinnati sensu LESS (ined.): tall-grass association, similar to the former one; with two sub-types: stipetosum, on dry, gravel-rich ridges, with rocky and steppe grassland species; danthonietosum, on deeper soil, with many meadow steppe tall forbs.
  3. Lino (tenuifolio) - Brachypodietum pinnati DOSTÁL (the former association is perhaps only a subassociation of this one): with high cover of tall-forb species (Linum spp., Apiaceae, Asteraceae).
  4. Poo badensis - Caricetum montanae ass. nova: short-grass association of sites with physical weathering and eluation. Characteristic is the presence of dolomit grassland species.
