The alliance Convolvulo-Elytrigion includes semi-natural and ruderal vegetation types of dry habitats with a high incidence of perennial grasses, some of them with extensive root or rhizome systems. Natural habitats of this vegetation type are slopes with occasional landslides or solifluction, particularly on soft sediments such as loess, where it borders on dry grasslands of the class Festuco-Brometea. In agricultural landscapes Convolvulo-Elytrigion communities are confined to the strips of land between roads and field margins and other anthropogenic habitats. Soils are loamy to clayey, often with high calcium content. This alliance is distributed in dry and warm areas of central, southern and eastern Europe.
