Calaminarian grasslands of the Violetalia calaminariae

Liste hiérarchisée et descriptifs des Habitats d'Intérêt Communautaire (HIC) de la directive "Habitats-Faune-Flore"

Définition EUR 28

Generally open natural or semi-natural grasslands 1) on natural rock outcrops, rich in heavy metals (e.g. zinc, lead), 2) river gravels and shingles, 3) on old terrils or spoil heaps around mines. These open grasslands are characterised by a highly specialised flora, with subspecies and ecotypes adapted to heavy metals. The threatened endemic taxa are generally absent from the pioneer vegetation of younger terrils. This pioneer vegetation is not considered to be a priority.
