✦ Synopsis

The environmental conditions for submerged macrophytes in sewage channels are different to those of natural waters. Mainly 6 eutraphent species occur in two communities on the flowing stretch of the Berlin treated sewage.channel Wuhle. The survival time of the above ground biomass of the annual species is relatively long due to the higher water temperatures in winter. The average biomass of the different parts of the flowing stretch is between 50 and 830 g DM/m2 in summer. With decreasing concentrations of ammonia and BOD an increase of the biomass and the colonization density could be noticed over the last few years.
