Vegetation of the Czech Republic
Salici purpureae-Myricarietum germanicae Moor 1958
This alluvial scrub is composed of open to closed stands of Myricaria germanica, which may be accompanied by shrubby willows such as Salix daphnoides, S. elaeagnos and S. purpurea. The stands may be 1–2 m tall. They occur on gravelly river terraces, especially those that are not affected by the strongest current during floods. They are occasionally flooded, but for most of the year the water table lies several dozen centimetres belowground. In the Czech Republic this vegetation historically occurred along several streams in the Moravskoslezské Beskydy Mountains in north-eastern Moravia, but most localities disappeared after streamflow started to be regulated in the second half of the 20th century. The only site where this vegetation currently occurs in its natural habitat is in the Morávka river floodplain near the village of Dobrá in north-eastern Moravia; here the Myricaria germanica population went extinct in the 1990s and was restored by planting individuals of local origin. However, stands corresponding to this association also developed in limestone quarries near Štramberk on the foothills of the Moravskoslezské Beskydy.
