Temperate high-mountain siliceous scree
Description (English)
Siliceous, mostly acidic screes, moraines or stone rivers found at high altitudes and cool sites in mountain ranges through the nemoral zone of Europe. The screes are colonized by a range of mostly perennial, mostly acidophilous plants. Their composition is strongly influenced by altitude and regional climate. There are many relict and local endemic species, though less than on calcareous screes. Often the vegetation cover is sparse, but these screes can be more humid because of the impervious and water-retentive character of the substrates and long snow-lie encourage luxuriant growth and accumulation of humus.

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.
