Vegetation dominated by the invasive neophyte Matricaria discoidea occurs on occasionally trampled sites with mesic loamy soils, often with an admixture of sand or gravel. It grows on roadsides, playgrounds, sand or gravel heaps or disturbed places where poultry is allowed to run free. Unlike the other communities of the class Polygono-Poëtea it is more typical of initial successional stages on recently disturbed sites than of frequently trampled habitats. In the Czech Republic this community is probably frequent, but not sufficiently documented. It occurs mainly in colline and submontane landscapes.
