MSFD cross-cutting workshop for GES
Decision review
21-22 January 2015, Copenhagen
Session 2
COHERENCE WITH
EXISTING EU AND RSC
STANDARDS & METHODS
Integration and streamlining
a. EU policies, RSCs and other international agreements
already address many MSFD-relevant issues
b. These often set standards and define methodologies
which can be adopted or adapted to MSFD needs
c. Integration of these into the Decision and ongoing
MSFD implementation could streamline the work
needed – do once, use several times
d. Follows overall goals expressed by EU Directors
(Nature, Biodiversity, Water and Marine) + joint
workshop December 2014
e. Sometimes technical detail of existing approaches
needs adaptation to suit MSFD – e.g. extend
geographic or topic scope, adapt to holistic MSFD
needs
ELEMENTS FOR
ASSESSMENT
Elements for assessment
We have:
a.
b.
c.
d.
EU agreed lists
International Convention agreed lists
RSC 'common lists' (for indicators)
Additional national elements, as specified by MS
• Should we develop:
a. Common EU lists to ensure consistency in
determination of GES and its assessment?
b. Regionally-specific lists (especially to reflect
ecosystem variation)?
Do we need:
a. Possibility to de-select, based on agreed
guidelines e.g. element not present in MS waters,
minimal risk from element to ecosystem?
Elements for assessment – draft lists

a. EU - Habitats and Birds Directive lists
b. International Convention lists
i.
ii.
RSCs – OSPAR, HELCOM, Barcelona, Bucharest(?) Conventions

Biodiversity elements
Issue:
a. Listed types were not selected to ‘represent’
biodiversity and ecosystems
b. They may not be good indicators of impacts from
pressures
c. If rare, they may be difficult to monitor - > poor
data sets for assessments

Discussion – elements for
assessment
To discuss/conclude:
a.Do we need a common list of elements at the EU level
and/or at the regional level? Based on agreed EU and
regional lists?
b.Can we represent biodiversity via a set of functional
groups and predominant habitat types – and assess via
specified species and habitats (from a ‘common’ list?)
c.Do we need a de-selection option? Based on what
principles?

Issues for biodiversity criteria
• Feasible to align MSFD and BHD criteria (and
IUCN)
• Similarities to D3 criteria
• Use of all criteria?
 often limitations on data for one or more criteria (even for
'data rich' commercial species)
 Threats are often on specific criteria (e.g. distributional
range is affected only for some species, rarely for habitats)
 Potential to prioritise criteria – primary and secondary (as
done for D3), based on risk?
Discussion:
a.How could we harmonise between MSFD and HBD, e.g. via
criteria, GES/FCS boundaries, assessment scales, timing?
b.Should differing importance/risk of criteria be accommodated in
their application (primary, secondary)?

Aggregation rules – pressure-based
descriptors
• Descriptors 2, 3, 5, 6, 7, 8, 10 currently have:
a. ‘Pressure level in sea’ criterion
b. ‘Impact of pressure’ criterion
[Descriptors 9 and 11 only have a ‘pressure-level’
criterion at present]
Discussion: aggregation rules
To discuss/conclude:
Biodiversity/ecosystems
a.Is the OOAO method appropriate between criteria for an
individual species or habitat?
b.Should we aim to express achievement of GES for biodiversity
by proportion of species/habitat that are in GES per broader
group (e.g. Y% of demersal fish are in GES, Z% of shelf
habitats are in GES) or consider other approaches?
Pressures/impacts
a.What aggregation method should be used for the pressurebased descriptors (pressure + impact criteria)?
b.Should we expect to achieve GES for all pressure-based
descriptors?
ASSESSMENT SCALES
Assessment scales and areas
1. MSFD provides broad architecture:
•
•
•
Regions
Subregions
Subdivisions
2. MS approaches in 2012 reporting
•
•
Principle: all assessments linked to a specified area
Reporting allowed for multiple possibilities – whole MS
marine waters, larger areas, smaller areas, different areas
per topic
3. 'Scales' project
•
•
Technical analysis – what was done, key issues to
consider
Initial guidance – broad approaches, lacks specific
guidance on ‘how to do it’, how to provide options to
ensure some coherence across MS
Way forward?
1. Need defined scale for each ‘quality element’
•
•
•
•
Basis for determining GES and undertaking assessments
Both can vary with scale
Links to coherence in delivery of marine strategies –
measures, exceptions, plans & projects
Agreed system for presentation of MSFD status at regional
and EU levels
2. Needs to be operationally practical
•
•
•
•
•
Provide clarity and certainty in MSFD implementation
(WFD and HD provide defined scales of assessment)
Links to MS jurisdictions
Relates monitoring/data to assessments
Not overly complex – avoid multiple scales across topics?
Appropriate scales for ecosystem, pressures and measures

Discussion: assessment scales
To discuss:
a.How should scales for pressure-based assessments relate to
state-based assessment scales?
b. Could state and pressure elements be broadly 'assigned' to
suitable scales (as per suggestion)?
c. How do we develop a more coherent system to enable an EUlevel assessment for 2018? Develop an initial proposal?
