This vegetation is characterized by the dominance or frequent occurrence of the low-growing grasses Digitaria ischaemum, D. sanguinalis. Eragrostis minor and Setaria verticillata, which attain their phenological optimum in August and September. It occurs either on arable land, especially in vegetable fields on well-drained soils, or at the edges of sidewalks, along roads or railway tracks or on ruderal sites on sandy soils. These habitats are often treated with herbicides. Stands of Digitario-Eragrostietum are scattered to common in warm areas of the Czech Republic.
