R1-A33 - Pelouses médio-européennes semi-sèches à Brachypodium

Middle European Brachypodium semidry grasslands

Classification des habitats EUNIS 2022

Descriptif de l'habitat

Brachypodium pinnatum ssp. pinnatum or Brachypodium pinnatum ssp. rupestre facies of unit R1A32. Geographical subdivisions are given by level 6 units R1A321 - R1A322 . Brachypodium-dominated facies may form in all the regional types of grasslands inventoried in unit R1A32 as a result of nitrification or of dominance of grazing over mowing. Such processes are accompanied by a drastic reduction in species diversity. South western grasslands of sub units H to K of R1A32 and of R1A33 are, however, generally rich in Brachypodium even in the apparent absence of degradation processes.
