Species-poor stands of the low-growing annual grass Aira praecox occur on acidic sandy soils with a slightly higher content of humus and fine soil particles than is typical of sand dunes. The habitats are usually trampled or disturbed in the top soil. This association is most frequent in areas with suboceanic climate and poor sandy deposits, especially in the Doksy region of northern Bohemia. It has been also rarely recorded along the Labe river, in the Třeboň basin of southern Bohemia, and elsewhere.
