Assessment areas - Charting Progress 2 (CP2) Regions

Marine Scotland Information NMPi icon

The 2010 Charting Progress 2 assessment (UKMMAS 2010) subdivided UK waters into eight regions to assess how human use and other pressures were affecting the productivity of UK seas. Regional boundaries were developed in 2009, adapting 'regional seas' previously identified on the basis of physical and biological biogeography by the Review of Marine Nature Conservation (RMNC) 2004. The CP2 'Reporting Regions' have subsequently informed a variety of MPA designation, marine assessment and reporting purposes and continue to be used, for example in the selection of Highly Protected Marine Areas, indicators for the ecological status of the water environment, and the aggregation of marine biotope sensitivity information.

JNCC updated the CP2 Reporting Regions dataset in 2022, making improvements to the inner (coastal) and outer (UK maritime limit) boundaries of the reporting regions. This incorporated up-to-date UK Exclusive Economic Zone and Continental Shelf limits and mean high water (springs) coastlines across the UK. No substantive changes were made to the biogeographic boundaries, but these were edited to join up with updated coastlines (as required) and minor topological issues (e.g. overlaps between polygons) were also addressed. See lineage for further details.

Note that the use of the CP2 Reporting Regions (or other biogeographic regions and assessment units) by JNCC, the SNCBs and other ALBs will vary by purpose. Variations of the CP2 Reporting Regions may be used for assessment purposes.

Data notes and limitations: • open data coastline datasets used in the 2022 update were of medium spatial resolution, lacking detail in some areas (e.g. sea lochs and islets in the Hebrides, Orkneys and Shetland, pladdies in Strangford Loch and islets around Northern Ireland). • part of the Scottish Continental Shelf (region 7) boundary was originally drawn to align with the UK Territorial Waters limit around Orkney and Fair Isle. This section of boundary has not been updated and therefore remains consistent with the biogeographic boundary created in 2009. • in the absence of formally agreed maritime limits, linework from the original 2009 CP2 Reporting Regions data set has been retained to represent the boundary between the Northern Ireland Inshore Region and Republic of Ireland inshore waters.

Broad Habitat - Broad-Scale Predictive Habitat Map (EUSeaMap2 - EUNIS) (WMS)

Output of the 2021 EUSeaMap broad-scale predictive model, produced by EMODnet Seabed Habitats. The extent of the mapped area includes the Mediterranean Sea, Black Sea, Baltic Sea, and areas of the North Eastern Atlantic extending from the Canary Islands in the south to the Barents Sea in the north. The map was produced using a "top-down" modelling approach using classified habitat descriptors to determine a final output habitat. Habitat descriptors differ per region but include: Biological zone Energy class Oxygen regime Salinity regime Seabed substrate Riverine input Habitat descriptors (excepting Substrate) are calculated using underlying physical data and thresholds derived from statistical analyses or expert judgement on known conditions. The model is produced using R and Arc Model Builder (10.1). The model was created using raster input layers with a cell size of 0.00104dd (roughly 100 metres). The model includes the sublittoral zone only; due to the high variability of the littoral zone, a lack of detailed substrate data and the resolution of the model, it is difficult to predict littoral habitats at this scale. EUSeaMap is classified into EUNIS 2019 level 3 (or more detailed levels where appropriate), EUNIS 2019 level 2 , EUNIS 2007-2011, the MSFD benthic broad habitat types, the HELCOM HUB classification in the Baltic, and the recently revised habitat classification in the Mediterranean. In the Black Sea, EUSeaMap is not classified into EUNIS 2007-2011 (due to inapplicability), but is classified according to a classification that was developed by EMODnet Seabed Habitats (Populus et a, 2017, and for a revised version Vasquez et al, 2020, See Online resources). Reports that provide methods used for the classification of the predicted habitats into the new 2019 EUNIS classification, regional classifications, and MSFD BBHT (v.2017) are linked in Online Resources. A report on the methods used in the 2021 version of EUSeaMap (Vasquez et al., 2021) and reports on previous versions (v2016 and V2019) are linked in Online Resources.
