Overview WFD Implementation

Common Wadden Sea Secretariat
RiverBasin Districts
(Status November 2003)
Delimitations
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
“Report 2005”
Identification of water bodies.
First characterization.
Preliminary assessment (likelihood that water bodies will not reach good status in 2005).
First Characterization

Criteria:
• Salinity
• Exposition
Water Body Types
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..)
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
Schiermonnikoog2005
Stade1997
Main reasons:- High nutrient inputs- High concentrations of specific pollutants
But: - Gaps of information / monitoring data - Lacking of reference values and quantitative
criteria
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
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.
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?
