Mapping and monitoring of aquatic macrophytes in standing water of Mecklenburg Western Pomerania in the context of observation from Natura 2000 habitats

Möbius, Friederike

Abstract

Most waterbodies in northern Germany are affected by anthropogenically-induced eutrophication. In order to determine water quality and trophic level of lakes in Mecklenburg Western Pomerania since 2002, about 450 lakes were mapped for abundances and composition of macrophytes. Only very few of them were classified to have excellent ecological conditions. Current data and long-term monitoring clearly show (1) a negative correlation between trophic level and macrophyte diversity as well as their deepest occurrence and (2) a decrease of overall species. Both tendencies probably reflect human activities.
