Task on Harmonisation of Freshwater Biological Methods Progress Report

This progress report presents the harmonisation task on freshwater biological methods, including an overview of methods, evaluation of their applicability, and identification of needs for development or harmonisation. The analysis includes comparability levels, needs for harmonisation, and potential common metrics. Sources of information include WFD-CIS Monitoring Guidance, Intercalibration metadata questionnaire, and CEN and ISO information. Conclusions highlight the need for better harmonisation and compatibility of methodologies for effective monitoring as required by the WFD.

Presentation Transcript

  1. Task on Harmonisation of Freshwater Biological Methods Progress Report Presented byAna Cristina Cardoso Joint Research CentreInstitute for Environment and SustainabilityInland and Marine Waters Unit

  2. Contents of the presentation • Harmonisation task sheet • Information available • First analysis • Timetable next steps

  3. Reasoning for task on Harmonisation • WFD Annex V 1.3.6 Standards for monitoring of quality elements • Methods used for the monitoring of type parameters shall conform to the international standards listed belowor such other national or international standardswhich will ensure the provision of data of an equivalent scientific quality and comparability • Intercalibration of Member States biological assessment systems

  4. WG2A ECOSTAT Meeting 15-17 Oct 2003: Presentation of outline for initiative on harmonisation of national biological monitoring systems More detailed description Harmonisation task sheet’ sent to ECOSTAT Members Dec 2003

  5. Task Team • Ana Cristina Cardoso (JRC-EEWAI) • Guido Premazzi (JRC,EEWAI) • Fabrice martinet (FR) • Maria Luisa Serrano (ES) • Marina Carstens (DE) • Teresa Rafael (PT) • Sebastien Birk (STAR) • Peter Hale (CEN)

  6. Harmonisation task sheet: Objectives • Overview of the biological methods currently in use • Evaluate applicability in monitoring and assessment of ecological quality as required by the WFD • Evaluate applicability as common metrics for the purpose of the intercalibration exercise • Identify potential needs for development of new methods or harmonisation of existing methods (link to CEN) • Evaluate applicability in monitoring and assessment of ecological quality as required by the WFD • Evaluate applicability as common metrics for the purpose of the intercalibration exercise

  7. Harmonisation task sheet: Analysis • Methods comparability level: • Sampling • Analytical • Assessment • Assessment of applicability to WFD:should use EQR-values including type-specific reference conditions for the biological quality elements

  8. Harmonisation task sheet: Analysis • Needs for harmonisation • Need for new methods • Possible common metrics

  9. Sources of information • Information on methodologies currently in use and in development in MS and CC • WFD-CIS Monitoring Guidance – Method’s Task Sheets • Intercalibration metadata questionnaire • Information compiled from FP5 research projects - STAR (WATERVIEW database) • CEN and ISO

  10. Information so far available

  11. WFD-CIS Monitoring WG Fact Sheets on Biological Methods: Lakes

  12. Overview of methods in Waterview database • Summarised in different tables according to sensitiveness to pressures: • Organic pollution • Morphological degradation • Eutrophication • Toxic substances • Acidification • General degradation

  13. Overview of European Watercourse Assessment Methods Waterview Database (http://starwp3.eu-star.at)

  14. Pressure eutrophication (continuation)

  15. IC metadata questionnaire asked if site selected was classified in compliance with the WFD requirements … Assessment made on non-WFD-compatible classification system for 65% for lakes and river sites and 80% for coastal sites

  16. IC metadata questionnaire • … give a description of the classification method used • Most countries considered the biological quality elements agreed to be in focus for IC • macroinvertebrate data for river • phytoplankton (often chl values) and physico-chemical data for lakes • phytoplankton, macroinvertebrates and physico-chemical data for coast • Methods used - sampling, analysis and metrics - are different between countries and even within a country (e.g. macroinvertebrate metrics for rivers)

  17. International standards -Lakes Phytoplankton: SW- phytoplankton composition, abundance and biomass, Utermöhl technique, CEN std under development Aquatic flora: FIN - Aquatic flora composition and abundance, CEN Initiative to develop a std relating to lake macrophytes Benthic invertebrate fauna: SW - exposed lake shores, kick-samples, ISO 7828:1985 for sampling UK - Chironomid pupal Exuviae Technique (CPET), CEN Std awaited

  18. International standards -Lakes Fish: SW - Composition , abundance and age structure of fish populations, Gillnets, proposed CEN Std, document CEN/TC 230/WG 2/TG 4 N28 UK - Composition and abundance of benthic invertebrate fauna, composition and abundance of aquatic flora: Predictive System for Multimetrics (PSYM). Ongoing work will result in a draft method for submission

  19. Conclusions • Little information of national methodologies is available for lakes • Some degree of harmonisation at national level but often non-comparability between countries • Not all biological elements are covered by the national monitoring • Most current available methodologies are not WFD compatible • For certain geographic areas or for some types there are good possibilities to identify common metrics

  20.
