UKTAG is a partnership of the UK environment and conservation agencies which was set up by the UK-wide WFD policy group consisting of UK government administrations. It was created to provide coordinated advice on the the science and technical aspects of the European Union's Water Framework Directive (2000/60/EC). More information about the group can be found in the about section. The technical guidance and recommendations UKTAG make can be found in the resources section, and information on past and present consultations in the stakeholder consultation section.
The alarm list contains species thought to pose a risk to surface waters and their ecological status under the EC Water Framework Directive, but whose presence has not yet been recorded in Great Britain.
The working paper outlining the impact classification of alien species has been updated (05/02/2014) following the completion of additional risk assessments by GBNNSS and Phase 3 of the review of Environmental Standards.
This classification method enables the assessment of invertebrates in rivers in relation to general degradation, including organic pollution. Whalley, Hawkes, Paisley & Trigg (WHPT) metrics replace the Biological Monitoring Working Party (BMWP) metrics used for status classifications in the first river basin planning cycle.
Phytobenthos are good indicators of nutrient enrichment and can be used to assess lake water quality. Diatoms are the main plant groups that we use because their silica cell walls make them easy to identify under the microscope.
