This community dominated by Chenopodium urbicum occurs on mesic to wet soils rich in calcium carbonate and nutrients. It is found on rubble of old village houses or barns, or at the edges of dung hills, often in places with dung water input. It develops from May to mid-summer. It is an archaeophytic vegetation type which has recently become very rare. It has been recorded on a few sites in warm areas of the Czech Republic.
