This species-rich association occurs in warm areas on base-rich soils. It includes several thermophilous annual weed species which germinate only in late spring. Its phenological optimum is in August and September when it develops on stubbles, recently abandoned fields, in vineyards and root-crop fields. Several rare and endangered annual weed species occur in this vegetation type. This association of Pannonian and Balkan distribution reaches its north-western range limit in the Czech Republic.
