Descriptif de l'habitat

Short open sward with a distinctive metallophyte component, occurring on shallow, skeletal soils over natural rock exposures with heavy metals in western and Central Europe, on mine spoil or ground contaminated by dust and waters from such sources. Typically it occurs in small patches in the landscapes, colonising slowly and sustained by the extreme environment. Sometimes it is dependent on grazing by wild herbivores that maintain early successional stages that are richer in cryptogams.
