This community type is dominated by Bunias orientalis, a biennial to perennial herb, which is a neophyte of Asian origin. It is capable of effective dispersal through generative propagules, though it can also form large clonal stands. It develops on disturbed sites along roads and railways, in abandoned fields and meadows or in industrial zones. Soils can be moderately wet to dry, with an intermediate nutrient status and often with high proportion of stones. In the Czech Republic this vegetation is spreading in lowland and colline areas.
