Temperate, lowland to montane siliceous scree
Description (English)
Siliceous screes and moraines of warm exposures, derived from a diversity of sedimentary, igneous and metamorphic rocks on the lower slopes of mountain ranges in the nemoral zone. Often the screes are mixed with fine soil. Vegetation can be completely lacking, but bryophyte or lichen-dominated, species-poor communities can occur on rock surfaces. The fine soil accumulated in crevices can support a variety of forb or fern-dominated vegetation. Siliceous screes, in general, have a lower species richness than calcareous screes but ferns can be diverse and luxuriant. Natural succession on more stable screes results in the development of scrub and woodland, not included here.

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.
