Vegetation of the Czech Republic

Alliance XBK
Eragrostion cilianensi-minoris Tüxen ex Oberdorfer 1954

The alliance Eragrostion cilianensi-minoris includes thermophilous vegetation occurring on sandy or gravelly soils and composed of low-growing species adapted to occasional trampling. In most stands the dominant species are annual grasses, many of them with a C4 metabolism. This vegetation attains maximum biomass in the dry and hot periods of mid-summer. The range of this alliance includes warm areas of central Europe and the Balkans.
