E1.264 - Niveau 5 : Pelouses alluviales et humides du Mesobromion
Description
Closed grasslands rich in species of the Mesobromion and in particular Bromus erectus, developed on calcareous marls, on somewhat elevated expanses of alluvial plains and on other water retentive soils within the range of the grasslands listed under E1.262. They are transitional to humid grasslands (E3) and are often marked by the abundance of Carex flacca. Among characteristic elements are also Thalictrum majus, Peucedanum carvifolia, Silaum silaus, Festuca hirundinacea. Geographical subdivisions can be introduced by use of the fourth decimal digit of E1.262 in the fourth place of E1.264. Extensive examples are known in particular from the marls of Lorraine, the Belgian low Meuse and the great rivers of the Netherlands, Westphalia, the alluvial plains of the French Moselle and Meuse, the Rhine valley in Germany and Alsace, various valleys in south Germany and the valley of the Sarthe.
