MSFD Com Dec 2010/477/EU review Recommendations for D1 14th meeting of the Working Group on Good Environmental Status (WG GES) 5th-6th October 2015 Francesca Somma - JRC D1 Biological diversity 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) Common list of elements: Species level Proposal for a revised list of species groups as the minimum D1 assessment elements Biodiversity Biodiversity groups Components (assessment units): Species group 1. Grazing feeders 2. Wading feeders Birds 3. Surface feeders 4. Pelagic feeders 5. Benthic feeders 1. Small toothed cetacean 2. Deep divers toothed cetacean Mammals 3. Baleen whales 4. Seals Reptiles 1. Turtles 1. Coastal Fish Cephalopod s SEC(2011)1255 2. Pelagic fish & elasmobranchs 3. Demersal fish & elasmobranchs 4.Demersal deep-sea fish & elasmobranchs 1. Coastal/shelf pelagic cephalopods 2. Deep-sea pelagic cephalopods Common list of elements: Habitats level Proposal for a revised list of habitats groups as the minimum D1 assessment elements; Correspondence between biodiversity habitats groups (minimum requirements) and proposed EUNIS 2015 typology Biodiversity Biodiversity habitat groups Components Benthic (former Littoral rock and biogenic reef seabed) habitats Littoral sediment Infralittoral rock and biogenic reef Infralittoral coarse sediment Infralittoral sand Infralittoral mud Infralittoral mixed sediment Circalittoral rock and biogenic reef Circalittoral coarse sediment Circalittoral sand Circalittoral mud Circalittoral mixed sediment Upper bathyal rock and biogenic reef Upper bathyal sediment Lower bathyal rock and biogenic reef Lower bathyal sediment Abyssal rock and biogenic reef Abyssal sediment Pelagic (former Coastal water column) Shelf habitats Oceanic SEC(2011)1255 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) Assessment framework for species groups Species group (e.g. shelf demersal fish & elasmobranchs) Overall GES assessment for a species group to feed the D1 Species Level assessment Aggregation rule for species Species A Species B Species C Representative species (criteria) Aggregation rule for relevant criteria Criterion 1.1 - distribution Criterion 1.2 – population size Criterion 1.3 – population condition GES boundary defined per criterion or indicator Data set A Data set B Data set C Input from other legislations and RSCs Assessment framework for habitats groups Habitat Group (EUNIS 2015 level 2) (e.g. circalittoral sand) Aggregation rule for criteria GES boundary defined per criterion Criterion 1.5 – habitat extent (proportion lost) Data set A extent of physical loss – from D6.1 (loss) Aggregation rule for methodological standards GES boundary defined per indicator Criterion 1.6 – habitat condition (proportion impacted) Data set B extent of physical damage – from D6.1 (damage) Subhabitat A Data set C on benthic condition from D1.6 Overall GES assessment for a habitats group to feed the D1 Habitat Level assessment Data set E, F etc extent of other impacts (e.g. D5 eutrophication, D2 NIS) Subhabitat B Data set D on benthic condition from D1.6 Representative habitats including also HD & RSCs listed habitats to assess condition 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)
