This classification method enables the assessment of invertebrates in rivers in relation to general degradation, including organic pollution.
The purpose of this report is to derive EQS for the substance emamectin benzoate for sediment and for water (protective of pelagic organisms).
This method statement describes how to determine the WFD class for the lake fish biological element.
This classification method enables the assessment of fish in rivers according to the requirements of the Water Framework Directive (WFD). It encompasses fish abundance, taxonomic composition and age structure.
Further to the UKTAG Biological and Environmental Standards consultation May 2019, the working paper outlining impact classification of alien
UKTAG has sought views and comments on the scientific work that underpins proposals for fish classification. This classification is designed for use in taking decisions under the Water Framework Directive (WFD).
A method statement describing how to determine the WFD class boundary values for the supporting element nitrogen in lakes. Environmental standards for total nitrogen have been developed for implementation in the third river basin planning cycle.
Phytobenthos are good indicators of nutrient enrichment and other pressures, and can be used to assess river water quality. Diatoms are the main plant groups that we use because their silica shells are easy to identify under the microscope.
Informative note on progress with, and the status of, recent developments in river phytobenthos analysis methods and the classification tool (DARLEQ) for the third River Basin Planning Cycle.
UKTAG has sought views and comments on the scientific work that underpins the latest set of proposals for biological and environmental standards. The standards are designed for use in taking decisions under the Water Framework Directive (WFD).
