2. River Basin Districts (Status November 2003) Delimitations

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

4. “Report 2005” Identification of water bodies. First characterization. Preliminary assessment (likelihood that water bodies will not reach good status in 2005). First Characterization Table 1: Available drafts of the Report 2005 (B-reports) River Basin DistrictWorking AreaDraft Report 2005 RBD RhineRhine Northversion October 2004 RBD Ems:Ems-Dollart Estuary version October 2004 Lower Emsversion 7.10.04 RBD Weser:Tideweserversion 4.10.04 RBD ElbeTideelbeversion 1.10.2004 RBD EiderEiderversion November 2003 RBD Sønderjylland - RBD Ribe-

5. Criteria: Salinity Exposition Water Body Types

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

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

8. WFD Objective „Good ecological status by 2015“ Assessment Ecological Status 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 Applicability in Policy and Management Suitability for Communication with Stakeholders Good: No scientific conflicts Good: Structuring of assessment and monitoring Structuring Policy and Management Guidance development of measures Regional specification Good: Regional and Sectoral Specification possible General Support Scientific Credibility
