Distribution.
This community is typically associated with arable crops on impoverished soils and is now very scarce, both because suitable soils have a localised distribution and because intensive cereal agriculture is not conducive to its development. It is found very locally, mostly in southern and eastern Britain, most often in fields of barley or fallow arable.
