24 - 25 March 2011, Greifswald, Germany
„Wetlands for clear water” was the title of the conference that took place on 24 – 25 March 2011 in the Hanseatic city Greifswald. The conference was organised by the Grűne Liga and the University of Greifswald. The main question addressed by the conference was: how can proper wetland management reduce total nutrient load to the Baltic Sea and tackle eutrophication?During the first day approximately 40 participants from Germany, Poland, Lithuania, Romania and other European countries could follow 12 lectures on restoration and creation of wetlands as nutrient traps for nutrients from diffuse sources (mostly from agriculture). Leading national and international speakers shared their perspectives and experiences in wetland management and provided a new understanding on the need and importance of nutrient retention processes occuring in wetlands for the health of the Baltic Sea ecosystem.
On the second day of conference an excursion to Penne and Trebel valleys was organized. Participants visited one of the best preserved calcareous fens in Western Europe near Gützkow supported by rewetting measures, with a very interesting landscape and high biodiversity. Another example of successful implementation of a rewetting project could be observed in Rustow-Randow Polder, where water tables were artificially set up by a system of dykes and pumps in 3 phases until the level of river Penne was reached. At the last stop of the excursion in Bruderdorf polder participants experienced an unsuccessful example of a restoration project: the improper operation of dykes and unstable water levels caused high nutrient dynamics and a suboptimal vegetation development.
