Temperate high-mountain base-rich scree and moraine

Description (English)

Calcareous and calcschist screes occurring at high altitudes and cool sites in high mountain ranges through the nemoral zone of Europe. The screes are colonized by mostly perennial basiphilous species, comprising often rich assemblages with many endemic species.

Flowering Plants Cerastium carinthiacum
Flowering Plants Doronicum grandiflorum
Flowering Plants Crepis pygmaea
Flowering Plants Viola cenisia

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.
