Mediterranean to Atlantic open, dry, acid and neutral grassland

Description (English)

Usually ephemeral vegetation related to the yearly cycle of spring rains and summer drought through the western Mediterranean and more fragmentarily into the Atlantic and continental areas where a high diversity of small annual plants make a brief, colourful appearance on bare patches of nutrient-poor, acidic soils. Typically, the habitat occurs as small patches in intimate mosaics with heath and scrub and has provided a valuable supplementary resource for sheep at lambing time.
