Subarctic and alpine dwarf Salix scrub

Description (English)

Salix-dominated dwarf scrub, often with abundant bryophytes and lichens, on skeletal calcareous or siliceous soils in late snow beds with a short growing-season, occurring in the subarctic north of the woodland zone and in the high mountains of nemoral Europe, increasingly local and fragmentary to the south.
