STATE OF PLAY
Since the 7th of April the final version of the review manual is
available on CIRCABC
Outstanding issues addressed at a workshop held on the 7-9
September 2015
Workshop report circulated for the WG GES meeting
Key outcomes from the D1
workshop
• Common revised list of species and
habitats groups as the minimum
assessment unit for biodiversity
• Selection criteria for inclusion of species
and habitats in a group
• Updated criteria and indicators for D1
• Assessment frameworks for species and
habitats (from data to GES assessment
at the group level)

Selection/deselection criteria
for the inclusion of species
and habitats in a group
Primary scientific criteria – ecological relevance for D1:
•
Representativeness of an ecosystem component
•
Species/ habitats vulnerable to a pressure
•
Key functional role of species/habitats
•
Sufficiently present across (sub)region
•
Present in sufficient numbers
Secondary practical criteria: Practical consideration, but which cannot substitute
to primary requirements:
•
Monitoring/technical feasibility
•
Monitoring costs
•
Reliable time series
Updated criteria and
indicators for D1
Species Level
1.1 Species geographic distribution
– 1.1.1 distributional range
– 1.1.2 distributional pattern, where relevant
– 1.1.3 area covered by species, where relevant
1.2 Population size
– 1.2.1 population abundance and/or biomass, as appropriate
1.3 Population condition
– 1.3.1 Population demographic characteristics (e.g. body size or age class structure,
sex ratio, fecundity rates, survival/ mortality rates)
1.4 Mobile species community composition
– 1.4.1 Relative abundance of community elements (e.g relative abundance of species;
relative abundance of large/small individuals; relative abundance of
sensitive/resilient individuals)
Updated criteria and
indicators for D1
Habitat level
1.5 Habitat geographic distribution and extent
– 1.5.1 Distributional range
– 1.5.2 Distributional pattern
– 1.5.3 Habitat extent (area and volume)
1.6 Habitat condition
– 1.6.1 Condition of the typical species and communities
– 1.6.2 Relative abundance and/or biomass, as appropriate
1.7 Ecosystem structure
– 1.7.1 Composition and relative proportion of ecosystem components (habitats and
species)

Follow up work for D1
•
Work on identifying a suited and common aggregation rule
for each step of the assessment process, where data need to be
aggregated
•
Further consideration of the special (listed) habitats for the
MSFD and how we can take stock of HD, WFD and RSCs
assessments
•
Working examples on the integration across descriptors for
the assessment of biodiversity groups and elements
•
Working examples on the new introduced criterion (1.4)
