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 Arctic and subarctic zones and in the high mountains of temperate Europe, increasingly local and fragmentary to the south.
Remark: This habitat also occurs in the Arctic zone (e.g. Svalbard), which is not reflected in its current name.
