Phytoplankton is one of the four key biological quality elements to be used in the ecological classification of lakes in Europe according to the Water Framework Directive (WFD). Chlorophyll a (Chla) has so far been used as the main – and sometimes

According to the EU Water Framework Directive all freshwater bodies must obtain good ecological status by 2015. In Denmark this means that all lakes with a surface area above 5 ha (∼600 lakes) must be evaluated individually and mitigation measures
