The alliance Atriplicion includes several associations of medium-tall to tall erect annual herbs (mainly from the Brassicaceae. Chenopodiaceae or Asteraceae), which occur in ruderal habitats. They occur on recently disturbed sites with exposed bare soils as initial stages of secondary succession, e.g. in construction areas or around farms. Soils are mostly mesic and available nutrients are moderate. Unlike in the alliance Sisymbrion officinalis, most of the dominant species are summer annuals that attain their maximum biomass from mid-summer to autumn. The alliance is widespread and common across central Europe and adjacent regions.
