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.
