WFD Cycle 2 lake chironomids classification

Alternative title(s)

Abstract

This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for Chironomids in lakes. Chironomid populations within any given waterbody closely reflect both the nutrient and pH conditions within the water body. Scoring systems that allow the impact of both pressures to be assessed have been developed. However, currently only the CPET nutrient scoring system has been through intercalibration and is used for water body classification under the Water Framework Directive (WFD). CPET is an important tool for monitoring large water bodies. Its passive sampling methodology, compared with the direct sampling methods used in all other ecological techniques makes it particularly good for representing ecological function and providing classification at a waterbody scale. The tool uses a series of predictor variables to produce a reference chrionomid community for the waterbody, which it then compares with the observed chrionomid community to produce an EQR value.

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.
