reference values1
Reference values
  • In Wadden Sea Plan (1997)
  • Targets:
    • Direction of development
    • Values mostly non-explicit
  • References values:
    • Explicit (e.g., hazardous substances)
    • Non-explicit
some examples
Some examples
  • Nutrients & Eutrophication
  • Hazardous substances
  • Salt marshes
  • Zostera fields
  • Blue mussel beds
  • Macrozoobenthos
1 nu trients and eutrophication
1: Nutrients and Eutrophication
  • Target:
    • A Wadden Sea which can be considered as a eutrophication non-problem area
  • Evaluation criteria:
    • Decreased nutrient input & concentrations
    • Decreased chlorophyll levels
    • Low occurrence of phytoplankton blooms
    • Low occurrence of green macroalgae
nutrients and eutrophication contd
Nutrients and Eutrophication – contd.
  • Reference values
    • P- and N-concentrations: as in the 1960s
    • Chlorophyll levels: ???
    • Phytoplankton blooms: ???
    • Green macroalgae: before 1980s
  • Reference values based on long-term data
2 hazardous substances
2: Hazardous substances
  • Targets:
    • Natural micropollutants: Background concentrations in water, sediment and indicator species
    • Man-made substances: Concentrations as resulting from zero discharges
  • Evaluation criteria:
    • Concentrations as in proper reference data
3 salt marshes
3:Salt marshes
  • Targets:
    • An increased area of natural salt marshes
    • An increased natural morphology and dynamics, including natural drainage patterns, of artificial salt marshes, […….]
    • An improved natural vegetation structure, including the pioneer zone, of artificial salt marshes
s alt marshes contd
Salt marshes – contd.
  • Evaluation criteria:
    • Area of natural salt marshes: hectares
    • Natural morphology & dynamics, ha without incl. natural drainage patterns: artif.drainage
    • Natural vegetation structure: ???

(alternative: diverse vegetation): (TMAP typology)

4 zostera fields
4: Zostera fields
  • Target:
    • An increased area of, and a more natural distribution and development of [……] Zostera fields
  • Evaluation criteria:
    • Increased area: ha & coverage
    • More natural distribution ….: ??? (habitat maps)
  • Reference: historic data (by region)
5 blue mussel beds
5: Blue mussel beds
  • Target:
    • An increased area of, and a more natural distribution and development of [……] blue mussel beds
  • Evaluation criteria:
    • Increased area: ha (harmonized method)
    • More natural distribution ….: ??? (habitat maps)
  • Reference:
    • Intertidal beds: historic data (range)
    • Subtidal beds: ???
6 macrozoobenthos
6: Macrozoobenthos
  • Targets:
    • A natural dynamic situation in the Tidal Area
    • An increased area of geomorphologically and biologically undisturbed tidal flats and subtidal areas
    • Favourable food availability for migrating and breeding birds
  • Evaluation criteria: ???
conclusions 1
Conclusions (1)
  • WSP Targets:
    • Defined in rather general terms
    • Defined as ‘directions’ (increase, decrease)
    • Not well defined in terms of measurable parameters
    • Not specified for different regions
conclusions 2
Conclusions (2)
  • Evaluation criteria:
    • Not always well defined
  • Reference values:
    • Partly available from long-term monitoring
    • Partly absent; to be defined
the way ahead
The way ahead
  • Ministerial Declaration, Esbjerg 2001
    • Implementation of § 81: “to further optimize the TMAP for future requirements, in particular with regard to the Targets, the EU Habitats Directive and the EU Water Framework Directive…”
  • TMAG: three step approach
tmag three step approach
TMAG: three step approach
  • Definition of common monitoring objectives
    • Combining requirements of EU Directives and Targets
  • Development of common monitoring programme
    • E.g., quantifiable monitoring objectives
  • Streamlining of assessment & reporting activities
    • Multi-use of national, trilateral and EU-reporting
