WFD Cycle 2 River Fish Classification

This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for fish in rivers. Fish can be used to indicate the ecological status of a river. Metrics on river fish composition, abundance and prevalence are run through the FCS2 classification tool. The actual (observed) values for these metrics are compared with a predicted value (reflecting a river in pristine condition). The comparison of the observed to expected values is known as an Ecological Quality Ratio (EQR). EQRs are used to produce a fish classification (High, Good, Moderate, Poor, Bad) of the water body for Water Framework Directive (WFD) purposes.
