WFD38: Phytoplankton Classification Tool for UK Lakes: WP1 Report on Potential Phytoplankton Pressure Sensitive Metrics (February, 2006) Project funders/partners: SNIFFER (WFD38) and Environment Agency (EMC(03)07) Background to research The Environment Agency and SNIFFER have commissioned this R and D project to develop a method to classify the ecological status of lakes on the basis of phytoplankton. As part of this assessment, metrics need to be developed for phytoplankton community composition. Objectives of research Specific objectives for the project were to develop a robust classification, incorporating: 1. Prediction of reference scores for UK lakes based on phytoplankton composition 2. Developing criteria for defining the good/moderate boundary 3. Classifying the ecological status of a water body in to one of five status classes (High/Good/Moderate/Poor/Bad), based on the calculation of an Ecological Quality Ratio (EQR). An EQR being calculated from the relationship between current observed and reference phytoplankton community composition for a site 4. Determining uncertainty associated with the classification result, based on statistical confidence or probability of class Key findings and recommendations This report provides an initial review of potential metrics available for assessing the ecological status of lakes using phytoplankton. Additionally, it outlines the data availability at the time of the start of the project. Guidance on sample collection and phytoplankton counting is also documented Key words: phytoplankton, WFD, classification, lake, ecological status, database i SNIFFER WFD38: Phytoplankton Classification Tool February, 2006 Acknowledgements The author would also like to thank Nigel Willby, Robert Ptacnik and Liisa Lepisto for discussions on potential methodological approaches available ii SNIFFER WFD38: Phytoplankton Classification Tool February, 2006 CONTENTS ACKNOWLEDGEMENTS II 1.
