Quantitative changes in the aquatic macrophyte vegetation of the Rosskopfarm backwater, on the River Danube below Vienna, were expressed by the composition and abundance of species, indicating "elementary ecotones". Their location is interpreted with respect to shading, hydrological dynamics and water depth. Sediment depth was statistically correlated with abundance values. The quantitative assay of the macrophyte vegetation was based on transect mapping across oxbow lakes (20 x 20 cm grid, 2-m width), which revealed detailed information on macrophyte stands and their structure at a very large scale. Mapping in subsequent years allowed preliminary evaluation of the stability of macrophyte-dominated elementary ecotones.
