This community is dominated by Chaerophyllum aureum, a broad-leaved perennial herb. It is found on partially shaded to sunny sites on roadsides, at the edges of fields, on disturbed stream banks, in scrub fringes, on ruderal sites in human settlements or in waste places. Soils are mesic and nutrient-rich, and often base-rich. In the Czech Republic it occurs only in the western half of Bohemia, particularly in submontane areas.
