WFD Cycle 2 TraC macroalgae classification
This dataset is a subset of “ WFD Classification Status Cycle 2” and contains classification data for the Macroalgae biological element in transitional and coastal water bodies. Macroalgae communities (seaweeds) can be used to indicate the ecological status of an estuary or coastal water body. A number of tools are used to measure metrics of composition and abundance for different types of macroalgae communities. Up to two tools used for assessing transitional water bodies are Opportunistic Macroalgae and Fucoid Extent. Up to two tools used for assessing coastal water bodies include Opportunistic Macroalgae and Rockshore Macroalgae. Each tool compares actual (observed) metric scores against reference conditions (reflecting a water body in pristine condition). The comparison of the observed to expected scores is known as an Ecological Quality Ratio (EQR). The EQRs score from the tool assessments are use to produce the Macroalgae classification (High, Good, Moderate, Poor, Bad) of the water body for Water Framework Directive (WFD) purposes.

The Water Framework Directive classification system is risk based and focuses on where there is likely to be a problem. It uses a principle known as "one out, all out", which means the poorest individual results drive the overall classification for a water body. It reports on over 30 quality elements, grouped into ecological status and chemical status. Ecological status includes physico-chem (e.g. nutrients, pH, dissolved oxygen, ammonia) , biological elements (e.g. phytoplankton, macroalgae, fish, invertebrates) , specific pollutants (e.g. metals and compounds, organic compounds) , hydromorphology (e.g. depth, width, flow, structure). Chemical status is assessed using priority substances, priority hazardous substances and other pollutants that present a significant risk to the water environment.
