Arrhenathero-Robinietum includes tall forests of Robinia pseudoacacia with straight trunks, which can grow as high as 30 m. The herb layer is dominated by the grasses Arrhenatherum elatius, Calamagrostis epigejos, Festuca ovina and Poa nemoralis, but other species can also occur and even dominate in places. Nutrient-demanding dicot herbs are rare. This association occurs in warm and dry lowland areas, mainly on sandy or gravelly terraces along large rivers such as the Labe in central and eastern Bohemia and the Morava and Dyje in southern Moravia.
