This alliance includes vegetation dominated by annual species of Atriplex and Chenopodium, which develops on slightly saline and ammonium-rich soils around dung hills and in places with agricultural waste water input, often near barns. They also occur on sediment accumulations along large rivers and on exposed bottoms of nutrient-rich fishponds. These substrates are usually rich in calcium and magnesium. The Chenopodion rubri alliance occurs in Europe and some parts of central Asia.
