This species-poor community is dominated by the annual herb Atriplex sagittata, which can form stands up to 2 m tall. It develops on bare soils exposed due to construction, in settlements, around farms and on road embankments. It can occur in places with increased content of chloride salts. Atriplex sagittata germinates in early spring and its stands are vital until autumn. Along with the association Chenopodietum stricti, it is the most common vegetation type of initial stages of secondary succession in and around human settlements in the Czech Republic. It is most common in warm lowlands, but it also occurs in moderately cool areas.
