37.23 - Subcontinental riverine meadows

Classification des habitats du Paléarctique (2001)

Description

Meadows of the valleys of great rivers of continental or subcontinental climate regions of Central Europe, submitted to repeated inundation periods in the year, characteristic of the Elbe, the Saale, the Main valleys of Germany, of Bohemia, Moravia, Austria and northeastern Croatia, with a disjunct outpost in the arid Rhine graben; they are usually dominated by Deschampsia cespitosa; characteristic species include Cnidium dubium (Cnidium venosum), Viola persicifolia, Allium angulosum, Iris sibirica, Oenanthe lachenalii, Oenanthe silaifolia, Gratiola officinalis, Juncus atratus, Leucojum aestivum, Carex praecox var. suzae, Lythrum virgatum. Because of universal river control schemes, these communities, dependent on natural or near natural flow regemes, are extremely threatened.
