Vegetation of the Czech Republic

Alliance TCB
Juncion gerardii Wendelberger 1943

Saline grasslands of the alliance Juncion gerardii are more closed and moister than those of the Puccinellion limosae. Physiognomically they resemble mesic pastures or ruderal grasslands influenced by grazing and trampling. They are distributed across temperate Europe from the precipitation-rich areas near the Atlantic coast to the continental parts of Russia. In the Czech Republic they are found in dry areas of northern and central Bohemia and southern Moravia.
