34.32 - Niveau 4 : Pelouses calcaires sub-atlantiques semi-arides
Description
More or less mesophile, closed formations dominated by perennial, tuft-forming grasses, colonizing relatively deep, mostly calcareous soils in the sub-Atlantic domaine of the Quercion pubescenti-petraeae and its northern irradiations and in the sub-Mediterranean mountains of the Italian peninsula, with Bromus erectus, Brachypodium pinnatum, Koeleria pyramidata, Festuca guestfalica, F. lemanii, Avenula pubescens, Sesleria albicans, Briza media, Carex caryophyllea, C. flacca, Gentianella germanica, G. ciliata, Gentiana cruciata, Trifolium montanum, Lotus corniculatus, Ononis repens, Medicago lupulina, Ranunculus bulbosus, Sanguisorba minor, Cirsium acaule, Euphrasia stricta, Dianthus deltoides, Potentilla neumanniana (= P. tabernaemontani, P. verna), Anthyllis vulneraria, Galium verum, Euphorbia brittingeri (E. verrucosa), Hippocrepis comosa, Helianthemum nummularium, Thymus praecox, Salvia pratensis, Linum catharticum, Scabiosa columbaria, Centaurea scabiosa, Carlina vulgaris, Viola hirta, Plantago media, Primula veris and numerous orchids such as Coeloglossum viride, Ophrys apifera, O. holoserica, O. insectifera, O. sphegodes, Aceras anthropophorum, Himantoglossum hircinum, Anacamptis pyramidalis, Orchis morio, O. ustulata, O. militaris, O. simia, Gymnadenia conopsea, Platanthera chlorantha, Herminium monorchis, Dactylorhiza fuchsii. Generally species-rich, these communities may be overwhelmed by the highly social Brachypodium pinnatum. Their range extends from the British Isles, Denmark, the Low Countries and northern Germany to the Cantabric range, the Pyrenees, Catalonia, the southern Alps, and the Central Apennines. Forming a bridge between the Mediterranean region and thermophile sites to the north, they can be identified by their high representation of Mediterranean species in the north and of Euro-Siberian ones in the south.

34.325 - Niveau 5 : Pelouses semi-sèches médio-européennes dominées par Sesleria
Description
Sesleria albicans-dominated facies of 34.322, often rich in dealpine species, occurring in particular in the Alpine and Pyrenean periphery, but also occurring locally, farther from the immediate Alpine influence, in anomalous stations such as steep, more or less shaded slopes or cliffs; Sesleria argentea-dominated grasslands of Alava and Navarra. Geographical subdivisions can be introduced by use of the fourth decimal digit of 34.322 in the fourth place of 34.323.
