R1L Madeiran oromediterranean siliceous dry grassland
Highly distinctive tussocky grassland, rich in endemics, restricted to mountains in Madeira, where it occurs in crevices and on ledges in siliceous volcanic rocks where the soils are kept permanently moist by the very humid climate. It typically occurs in mosaics with heaths and forests, being threatened by the decline of domestic goat grazing.
