R1-J - Pelouses sèches siliceuses oroméditerranéennes cyrno-sardes

Cyrno-Sardean oromediterranean siliceous dry grassland

Classification des habitats EUNIS 2022

Descriptif de l'habitat

Grassland of base-poor soils over siliceous bedrock on the slopes and crests of high mountains in Corsica and Sardinia, with a short growing season and harsh winters when strong winds blow the ground free of snow and leave the surface subject to deep cold which encourages the development of freeze-thaw features. The cover of vegetation is intermediate to complete, dominated by prostrate herbs, cushion plants and dwarf shrubs, and includes many endemics.
