Alliance THG
Koelerio-Phleion phleoidis Korneck 1974

The alliance Koelerio-Phleion phleoidis includes dry grasslands on acidic soils developed over granite, gneiss and other siliceous bedrock types. Its species composition has transitional features linking dry grasslands of the alliances Festucion valesiacae and Bromion erecti, and sand grasslands of Armerion elongatae. These grasslands are mainly found in dry areas, since in wetter areas (usually at higher altitudes) dry grassland species tend to avoid acidic soils. In the past, these grasslands were used for low-intensity grazing. The distribution range of this alliance includes dry regions of Central Europe.
