This association is dominated by the low-growing, perennial grass Cynodon dactylon, which is able spreading extensively by means of its above-ground, creeping stolons. It is accompanied by a suite of annual species and trampled site specialists. It occurs in disturbed, sunny habitats on well drained sandy soils. It does well on exposed sandy sites, along roads and sidewalks in cities and villages, between railway tracks or in factory yards. It reaches maximum biomass in August and September. There are scattered occurrences of this association in warm areas of the Czech Republic.
