Cryptogam- and annual-dominated vegetation on siliceous rock outcrops
Description (English)
Open pioneer grassland dominated by perennial succulents and annuals, with subordinate small tussock grasses, sometimes geophytes and often a prominent contingent of cryptogams. Typically forming small stands on very shallow and skeletal, impoverished, acid soils on siliceous rock outcrops, eroded slopes and disturbed or artificial habitats like soil heaps and wall tops, the habitat occurs throughout temperate and boreal Europe up to the subalpine belt, in situations where the permeable soils dry quickly in summer, but where spring rains can permit a quick flush of growth by the annuals.

Not availableIndicator species
Diagnostic species occur concentrated in the habitat in question, but are absent or rare in other habitats. They are good positive indicators of the habitat, but they do not need to occur in every location of the habitat.
