Drylands with shrub cover greater than 10%, and with a large component of non-vernal unpalatable plants, including geophytes of the genera Asphodelus and Drimia, thistles such as Carlina, Carthamus, Centaurea, and Onopordum, and other plants such as Ferula and Phlomis, especially characteristic of the drier parts of the Mediterranean Basin but occurring elsewhere with suitable conditions such as the dry continental valleys of Switzerland. These habitats usually result from over-grazing of garrigue, which eliminates the shrubs.
