The website is currently undergoing some changes, including improvements to the search facility and labelling/tagging of documents. It will take a few weeks for all the documents to be checked to ensure tagging is correct, but if you have any feedback please get in touch via the "Contact us" link at the top of the page.
All of the relevant information on standards and typology for phosphorus in lakes is in the ministerial directions of the relevant administrations; DEFRA, WG, SG and DOENI. There is currently no specific / separate method statement.
This method statement provides guidance on the use of the metal bioavailability assessment tool (M-BAT) for practitioners involved in monitoring, assessment and classification using the new EQSbioavailable that have been developed for a number of metals under the Water Framework Directive (WFD). The document and tool covers copper, zinc, manganese and nickel.
This classification method encompasses fish abundance, taxonomic composition and age structure. The tool relates the number of salmon and trout caught in a survey to the predicted abundance and prevalence of the species at the specific site.
Macrophytes provide habitats for fish and smaller animals; they bind sediments, protect banks, absorb nutrients and provide oxygenation. Macrophytes can indicate the impact of increased nutrients in lakes and are also influenced by other pressures such as water level change or acidification.
