  1. TMAP – WFD Workshop ReferenceValuesHamburg 29 – 30 November 2004 Overview WFD Implementation Harald Marencic Common Wadden Sea Secretariat

  2. Delimitations River Basin Districts (Status November 2003)

  3. Delimitations RBD Wadden Sea River Basin Districts (RBD) in the Wadden Sea (coastal and transitionalwaters, up to 1 sm) (Inland areas and Helgoland not included)

  4. First Characterization “Report 2005” Identification of water bodies. First characterization. Preliminary assessment (likelihood that water bodies will not reach good status in 2005). Table 1: Available drafts of the Report 2005 (B-reports)

  5. Water Body Types • Criteria: • Salinity • Exposition

  6. Heavily Modified Water Bodies (HMWB) Preliminary Designation: • Criteria: • Hydro-Morphology significantly changed • Human uses (shipping, harbor, drainage..) • Transitional waters as „HMBW“ (Ems, Weser, Elbe, Eider) • Coastal Waters as „Natural Waters“ Discussion in NL: Loss of salt marshes due to embankments: Wadden Sea as HMWB ?

  7. Assessment Ecological Status Preliminary conclusions Draft Reports 2005(RBD Ems, Weser, Elbe, Eider) “Wadden Sea will probably not reach the environmental objectives / good status by 2015“ • But: • Gaps of information / monitoring data • Lacking of reference values and quantitative criteria • Main reasons: • High nutrient inputs • High concentrations of specific pollutants Stade 1997 Schiermonnikoog 2005

  8. Assessment Ecological Status WFD Objective „Good ecological status by 2015“ Good ecological status is a condition in which: - Biological quality elements show only slight deviation from the type-specific reference condition - Physico-chemical elements are at levels capable of supporting the functioning of the type-specific ecosystem

  9. Definition of Reference conditions • A condition in which a water body has suffered no, or only very minor anthropogenic impacts to its hydromorphology, physico-chemistry, and biology, • Can be in the past or the present, • Can be derived from observations, historical data or modelling, or where necessary expert judgement, • Can be expressed as ranges.

  10. Reference conditions – Work status • Van der Molen (Ed.) July 2004: “References and classification tools for transitional and coastal waters” • proposal reference values for 42 water types, • not yet tested, • “living document” • Dick de Jong , 2004. Determination of Reference conditions for plants in coastal waters. • development of “potentional GES” • projects on national and EU level • Others?

  11. Wadden Sea Plan Targets Ecological Targets Tidal Area Salt Marshes Beaches and Dunes Estuaries Offshore Zone Rural Area Quality of Water, Sediment and Biota Marine Mammals Birds Landscape and Cultural History Targets

  12. Wadden Sea Plan Targets 10 Years Experience Scientific Credibility Good: No scientific conflicts Applicability in Policy and Management Good: Structuring of assessment and monitoring Structuring Policy and Management Guidance development of measures Regional specification Suitability for Communication with Stakeholders Good: Regional and Sectoral Specification possible General Support

  13. Water Framework Directive and Wadden Sea Denmark: Ribe, S-Jutl.,, Eider Guidance from EU Level CIS Guidance documents (monitoring, reference condition, typology, classification) Eutrophication assessment guidance Schleswig-Holstein: Elbe, Eider Intercalibration process (metrics, class boundaries) Differences in interpretation and specification on RBD level Hamburg: Elbe Lower Saxony: Ems, Weser, Elber NL: Rhine North, Ems

  14. Water Framework Directive and Wadden Sea Denmark: Ribe, S-Jutl.,, Eider Guidance from EU Level CIS Guidance documents (monitoring, reference values, typology, classification) Eutrophication assessment guidance Schleswig-Holstein: Elbe, Eider Intercalibration process (metrics, class boundaries) Trilateral Cooperation / TMAP as „Platform“ to support RBD to find a common Wadden Sea approach. Hamburg: Elbe Lower Saxony: Ems, Weser, Elber NL: Rhine North, Ems

  15. Wadden Sea Symposium 2005 11th International Wadden Sea Symposium Esbjerg, 4 – 8 April 2005 Organized by: National Environmental Research Institute (NERI) Monitoring and Assessment in the Wadden Sea –Foundations and Perspectives Call for papers / Registration: 15 February 2005 Preliminary Program and Registration Form: www.waddensea-secretariat.org
