U6-2 - Champs de lave méditerranéens, macaronésiens et tempérés

Mediterranean, Macaronesian and temperate volcanic field

Classification des habitats EUNIS 2022

Descriptif de l'habitat

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.
