WFD Cycle 2 TraC angiosperm classification

Alternative title(s)

Abstract

The dataset is a subset of “WFD Classification Status Cycle 2” and contains classification data for the Angiosperm biological element in transitional and coastal bodies. Angiosperms are flowering plants and include seagrasses and saltmarshes within the marine community. Separate assessment tools for seagrass and saltmarsh are used to measure metrics of composition and abundance. 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 EQR score from the tool assessments are used to produce the Angiosperm classification (High, Good, Moderate, Poor, Bad) of the water body for Water Framework Directive (WFD) purposes.

Quality and validity

Lineage

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.
