Description
Abstract:
Abstract: The published Excel files contain the macrophyte and water quality data that where analysed in the article “How much information do we gain from multiple-year sampling in natural pond research?” The ponds were located in three regions in the intensively cultivated agricultural young moraine landscape of the state of Brandenburg, Germany. Sampling was performed once a year at the climax of the macrophyte growing season (between the end of July and the end of August) in the period from 1994 and 1999. We considered nine physicochemical water quality parameters, i.e. pH, electric conductivity, water temperature, oxygen concentration, chloride, sulphate, (ammonium) nitrogen, soluble reactive phosphorous and total phosphorus. Macrophyte species and coverage (i.e., aggregated coverage of vascular plants, Characeae and filamentous algae) growing in the inundated area of the kettle hole were mapped. Macrophyte coverage was determined in 1 to 5% percentage steps and converted to the 14-part Londo scale.
