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 method statement describes a system for assessing and classifying surface water bodies (rivers, lakes, transitional and coastal) based on the presence of high impact alien species.
The Final Recommendations on Environmental Standards following phase 3 of the review have been published (November 2013). This report includes zinc standards.
Following a consultation that ended on 28th February 2013, UKTAG has finalised its recommendations on 1) biological standards for rivers, lakes, coastal and estuaries and 2) phosphorus standards for rivers.
The UK Technical Advisory Group (UKTAG) has commissioned a programme of work to derive Environmental Quality Standards (EQSs) for substances falling under Annex VIII of the Water Framework Directive (WFD).
A technical report on proposals for a first set of standards and conditions was published for review in 2006. The revised report was issued in August 2006 in the form of a recommendation to the UK governments. The UKTAG updated the report in November 2007.
This is a technical report that presents the first set of environmental standards and conditions proposed by the UKTAG to underpin the implementation of the Directive. Our report outlines the background to our proposals and describes the role they could play.
The paper sets out UKTAG’s guidance on the framework for the identification of, and assessments of risks from, abstraction and flow regulation pressures on river, lake, transitional and coastal water bodies as required by Article 5 of the Directive.
