Übersicht über die synanthropen Pflanzengesellschaften und ihre Verbreitung in Flusshäfen Mitteleuropas (Vorläufige Mitteilung)

Between 1968 and 2007 the flora and vegetation of river harbours in Central Europe was studied. This paper deals with the assoziations and their distribution in 62 river harbours of two river systems. The assoziation Sisymbrio loeselii-Atriplicetum micranthae JEHLÍK et DOSTÁLEK 2008 ass. nova is described newly. The main difference between the two systems Elbe-Moldau-system and Donau-system are pointed out.
