Mediterranean, Macaronesian and temperate volcanic field

Description (English)

Sparsely vegetated volcanic areas of Mediterranean and Macaronesian regions, comprising mostly recently deposited volcanic scoriae (tephra), lava flows or orifices in volcanic areas emitting hot gases and vapours in Italy and the Canary Islands. Intense solar radiation, remarkable daily temperature variations, long-lasting snow-cover and mechanical disturbances caused by strong winds are usual conditions for this habitat type. Large areas are completely unvegetated or only covered by some bryophytes and lichens or a scattered and, on fragmentary soils, a discontinuous cover of a few, vascular plants.

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.
