Releve data from a historical-ecological study of the amphibious vegetation of shallow lakes at Turnhout, Belgium. Releves are comprised from the study period (1999, by Floris Vanderhaeghe) and from older times (1973-1993, by Geert De Blust and including 1 releve by Herman Stieperaere). Many of these phytocoenoses belong to the Littorelletea class.
