This community is dominated by goosefoot species of the Chenopodium album agg., mainly C. album s. str., C. opulifolium, C. pedunculare, C. strictum and C. suecicum. It occurs in loamy to skeletal, base-rich, mesic to dry soils on old building rubble, refuse dumps, roadworks and on construction sites. It is an intermittent community which retreats in a few years due to either disturbances or successional changes. Dominant species germinate in late spring and reach their phenological optimum in late summer and early autumn. In the Czech Republic this is one of the most common types of ruderal vegetation in early successional stages.
