This site summary was adapted from the Nature Conservation MPA site summary and incorporates any information gathered since this document was produced. Please refer to this document for further details and information sources.
Lying to the north of Scotland in offshore waters, the West Shetland Shelf Nature Conservation MPA has been designated for the protection of the wide variety of sand and gravel habitats (habitats of priority importance) present in the area, providing an important example of the northern extent of their range on the continental shelf in Scottish seas.
Although a relatively common habitat in Scottish seas, the range of different types of sand and gravel habitats present within the MPA support a particularly rich diversity of wildlife. On the surface anemones, cup sponges (Axinella infundibuloformis) and several types of crustaceans including hermit crabs and squat lobster (Munida rugosa) can be found living between small rocks, whilst urchins and starfish (such as Porania pulvillus and Asterias rubens) are typical fauna living on the surface of sandier sediments. Bryozoans and encrusting sponges are often found growing on the surface of cobbles and pebbles. Sea snails and bivalves, such as scallops, keel worms and sand mason worms (Lanice conchilega), are adapted to living buried in the sand to avoid predators.
The area enclosed within the MPA is also important for several species of fish, including the dragonet (Callionymus lyra), red gurnad (Aspitrigla cuculus), cod (Gadus morhua), plaice (Pleuronectes platessa), bass (Dicentrarchus labrax), and skate and rays (e.g. Raja naevus).
Site location: Co-ordinates for this Nature Conservation MPA can be found in the designation order.
Site area: 4,083 km2, a size similar to the Cairngorms National Park (4,508 km2).
Site depth range: 70–150 m.
Charting Progress 2 Biogeographic Region: Scottish Continental Shelf.
Site boundary description: The MPA boundary encompasses the distribution of a range of offshore subtidal sand and gravel habitats present within the area, providing an important example of the northern extent of their range on the continental shelf in Scotland’s seas.

For a full overview of the data used to support site identification along with information on confidence in feature presence and extent see the West Shetland Shelf Nature Conservation MPA Data Confidence Assessment.
Data for this Nature Conservation MPA have been primarily collected through JNCC-funded or collaborative surveys with other data obtained through other data sourcing. The data gathered provide direct evidence confirming the presence of the protected features within the site. Additional survey data will be added to JNCC's MPA mapper in due course.
Survey and data gathering
- Monitoring survey of West Shetland Shelf MPA and adjacent areas (2019) – This survey was a collaborative effort between JNCC and Marine Scotland Science and will contribute to the development of a monitoring time-series, against which the rate and direction of any change in the condition of the MPA features can be assessed.
- RV Scotia Rona-Windsock Survey (2011) – This survey was a collaborative effort between JNCC and Marine Scotland Science to improve our understanding of the species and habitats present within the MPA.
- Marine Scotland Science International Bottom Trawl Survey (2011) – This bottom trawl survey collected data on the fish populations in the MPA. Environmental information, including seabed samples and underwater imagery were collected to aid habitat classification and identify fauna present.
- RRS Charles Darwin Cruise (112C; 1998) – This cruise formed part of the Atlantic Margin Environmental Survey (AMES) programme, surveying the continental slope to the north and west of Shetland. Seabed samples, acoustic data and underwater imagery including photographic images and videos were collected.
Data analysis reports
- Seabed imagery analysis from the Firth of Forth Banks Complex, IBTS Q4 and deep-water sites survey (2014) – JNCC commissioned Seastar Survey Ltd to analyse the data collected from three Scottish offshore surveys undertaken by JNCC and Marine Scotland Science in 2011, to locate priority marine features in Scottish waters.
- Seafloor biotope assignment of grab samples from four surveys undertaken in 2011 across Scottish seas (2014) – JNCC commissioned Gardline Caledonia Ltd in 2012 to analyse benthic grab samples collected during four surveys (including the 2011 RV Scotia Rona-Windsock survey) to assign biotope classifications, identify priority marine features and further understanding of the distribution of MPA search features across Scotland’s seas.
- Seabed imagery analysis from three Scottish offshore surveys: MSS IBTSQ3, 1111s FRV Scotia Rona-Windsock survey and MSS Rockall survey (2014) – JNCC commissioned contractors to analyse the seabed imagery data collected from three Scottish offshore surveys undertaken by JNCC and Marine Scotland Science in 2011, to locate priority marine features in Scottish waters.
- Seafloor biotope analysis of the deep waters in the SEA4 region of Scottish seas (2012) – JNCC commissioned a contract to identify representative biotopes of the SEA4 region. The report drew on survey data collected by the 1998 AFEN survey and 2000 National Oceanography Centre led RRS Charles Darwin cruises.

Last updated: March 2018
Updated formal conservation advice for this MPA was produced in March 2018. Further information on the approach used to develop this advice is available on our Conservation Advice webpages along with a Glossary of Terms used in JNCC's conservation advice and a short video explaining how to use the conservation advice packages.
You must refer to this advice if you:
- undertake an impact assessment for a plan or project that could impact the site;
- provide information for such an assessment;
- respond to specific measures to further the conservation objectives for the site; and
- consider the need to put new or additional management measures in place.
You may also find it useful to refer to this advice if you:
- carry out any other activity that could impact the site.
We will engage with stakeholders to identify any lessons which JNCC can learn from customers who have used the advice, with a view to continuing to ensure it is fit-for-purpose.
The following table provides an overview of the components of the conservation advice, and provides hyperlinks to each of the products for this MPA. These elements together form JNCC’s formal conservation advice for this site and should be read in conjunction with each other. This advice reflects the most up-to-date evidence held by JNCC (correct as of March 2018).
|Background Information||Explains the purpose of the advice and when it must be referred to.|
The Conservation Objectives set out the broad ecological aims for the site. JNCC provides supplementary advice in the SACO which is essential reading to support interpretation of these conservation objectives.
You can use these documents to assess the impacts of your planned activity on the important attributes of the site.
Please note our current understanding of whether the available evidence indicates that each attribute needs to be recovered or maintained is not provided here. However, links to available evidence for the site are provided and should you require further site-specific information for the site, please contact us.
|Conservation Advice Statements||
These statements provide a summary of the Supplementary Advice on the Conservation Objectives (SACO).
|Feature Activity Sensitivity Tool (FeAST)||
Provides an initial assessment of whether a proposed plan or project (or ongoing activity) may have an impact on a protected feature in the site.
FeAST identifies pressures associated with the most commonly occurring marine activities, and provides detailed assessment of feature sensitivity to these pressures. A human activity is considered capable of affecting a feature where the feature is known to be sensitive to associated pressures.
The sensitivity assessments provided in FeAST should be used at an early stage of a plan or project when considering potential impacts of an activity.

Activities and Management
Last updated: October 2017
Management status: Progressing towards being well managed.
Progress is ongoing with baseline site condition monitoring work occurring in October 2017 to further our understanding of the degree to which the site is moving towards or achieving its conservation objectives.
This site forms part of the UK's contribution to the OSPAR Commission’s network of MPAs. As the UK is a contracting party to the OSPAR Commission, JNCC is committed to ensuring that the OSPAR MPA network is well-managed.
JNCC considers well-managed to mean the timely progress of an MPA around the 'MPA management cycle'. This involves:
- The documentation of appropriate management information – conservation objectives, advice on activities capable of affecting the protected features of a site, and spatial information on the presence and extent of the protected features of a site.
- The implementation of management measures – management actions considered necessary to achieve the conservation objectives of a site.
- Site condition monitoring programmes – collecting the information necessary to determine progress towards a site's conservation objectives.
- Assessment of progress towards conservation objectives – using available information to infer whether or not a site is moving towards or has achieved its conservation objectives.
The sub-sections that follow provide an account of the progress of the West Shetland Shelf Nature Conservation MPA around each of these four stages in the MPA management cycle.
1. The documentation of appropriate management information
- The conservation objectives and advice on activities capable of affecting the conservation status of the protected feature of this site are available under the Conservation Advice section. Further information is available on our 'Conserving MPAs' webpage.
- Spatial information on the presence and extent of the protected feature of this MPA is available via JNCC's MPA mapper.
- JNCC is in the process of developing downloadable MPA data packages where appropriate permissions to share datasets are in place.
2. The implementation of management measures
This section details progress towards the implementation of management measures for activities considered capable of affecting the conservation status of the protected features of the site. The protected features of the site are considered to be sensitive to pressures associated with fishing and 'licensable' activities.
- The main fishing practices in the area involve creeling and potting. UK potting vessels operate widely across the West Shetland Shelf Nature Conservation MPA. There is also evidence of Irish potting effort concentrated in the south-west of the MPA.
- The Technical Conservation Regulation 850/98 delineated an area closed to mobile fishing gears known as the ‘windsock’ which overlapped the West Shetland Shelf MPA, offering some protection to the benthic features of this site. However, new Technical Conservation Regulations (Regulation (EU) 2019/1241) were introduced in 2019 lifting the windsock restrictions as of 14 August 2019.
- Marine Scotland is the lead authority regarding the implementation of, and compliance with, any measures to managing fishing activity. Further information on progress is available via Marine Scotland's webpages.
- A very small part of the north-east of the MPA overlaps with license blocks identified by the department of energy and climate change. Although no oil and gas activity takes place within the region, the license blocks may be subject to development in the future.
- Existing licensed activities that take place or may take place in the future within West Shetland Shelf Nature Conservation MPA will continue to be managed in line with relevant legislation and application processes by the competent authorities. For further information, please see Marine Scotland’s MPA Draft Management Handbook. Information on JNCC's role in the provision of advice for licensed activities in the UK offshore area is available on the offshore industry advice webpages.
- Telecommunication cables currently cross the MPA at the north-east boundary of the site.
- Cables are largely an unregulated activity in offshore waters depending upon the type of cable being laid (or maintained), where it is being laid between, and whether the cable is part of a larger development (which may be regulated). Any cable not directly associated with an energy installation does not require a marine licence beyond 12 nm.
- JNCC encourages early discussion from operators regarding any plans related to new or existing cables, and encourages the undertaking of non-statutory environmental impact assessments for new or existing cable projects to assess their effect on the protected features of the MPA.
- Under international law, ships have a right of passage at sea including in areas designated as MPA's (unless management specifies the restriction of ship transiting as outlined through an international maritime organisation measure). The pressures associated with shipping activity within West Shetland Shelf Nature Conservation MPA are not considered likely to impact the protected features of the site.
- Wrecks have been recorded by the UK Hydrographic Office within the site.
3. Site condition monitoring
A baseline site condition monitoring survey took place within this MPA in October 2017. Further information will be made available in the Monitoring section in due course.
4. Assessment of progress towards conservation objectives
No long-term condition monitoring data is currently available to determine whether the MPA is moving towards or has reached its conservation objectives. Further information will be provided in the Assessment section as it becomes available.
Last updated: October 2017
JNCC is currently leading on the development of a strategy for biodiversity monitoring across all UK waters, to include Nature Conservation MPA monitoring. For Nature Conservation MPAs, data and evidence collected from monitoring activities will aim to:
- enable assessment of condition of the features within sites;
- enable assessment of the degree to which management measures are effective in achieving the conservation objectives for the protected features;
- support the identification of priorities for future protection and/or management; and
- enable the government to fulfil its national and international assessment and reporting commitments in relation to MPAs and help identify where further action may be required.
Information on monitoring of this MPA will be provided when it becomes available.
Last updated: October 2017
Assessments of the condition of designated features in offshore MPAs are required to report against our legal obligations. Ideally these assessments are based on observed data, and then measured against targets for pre-defined indicators. However, for MPAs in offshore waters we do not always have the appropriate information to be able to do so. This is particularly true for seabed habitats, which are the main type of feature designated for protection in offshore MPAs.
To address these challenges, JNCC has been an active partner in developing new approaches and tools for the assessment of habitats and species for a variety of national and international status reports.
Conservation Assessment Reports
Under Section 124 of the UK Marine & Coastal Access Act (2009), JNCC is required to report to Ministers every six years on the degree to which the conservation objectives of the protected features of a site have been achieved. Every six years from 2012, the Marine Act requires a report setting out how Nature Conservation MPAs have performed against their conservation objectives, as well as the effectiveness of the network as a whole. Marine Scotland has published a report setting out progress being made in implementing a Marine Protected Area network that supports the Government’s vision of clean, healthy, safe, productive, biologically diverse marine and coastal environment, managed to meet the long-term needs of nature and people.
Outputs of assessments that feed into Marine Act reporting will also feed into reporting under other obligations.
Charting Progress 2 (CP2) published in 2010, is a comprehensive report on the state of the UK seas. It was published by the UK Marine Monitoring and Assessment Strategy (UKMMAS) community which has over 40 member organisations. The report was based on a robust, peer-reviewed evidence base and describes progress made since the publication of Charting Progress in 2005. It provides key findings from UK marine research and monitoring for use by policy makers and others, as we move towards the UK vision of clean, healthy, safe, productive and biologically diverse oceans and seas. The results from CP2 were incorporated into the UK Marine Strategy Part 1: UK Initial Assessment and Good Environmental Status published in 2012 under the UK Marine Strategy Regulations (2010). The UK Marine Strategy Part 1 (2012) also set out the UK’s definition for Good Environmental Status, which could be achieved by meeting a series of environmental targets. JNCC worked with other organisations in the UKMMAS community to develop a series of indicators that were used to assess progress against each of the targets and to report on progress made since 2012. The results of these assessments have been published in the UK Marine Strategy Part 1: UK Updated Assessment and Good Environmental Status in 2019. Detailed evidence used to make these assessments is available via the Marine Online Assessment Tool (MOAT). It also sets out proposals for updated high-level objectives, targets and operational targets to be used for 2018 to 2024, which build on those set in 2012.
It is worth noting the two other parts of the UK Marine Strategy: UK Marine Strategy Part Two: marine monitoring programmes, published in 2014 and UK Marine Strategy Part Three: programme of measures published in 2015. Updates to these will be made in 2020 and 2021 respectively.
OSPAR Quality Status Reports
Many of the assessments in the updated UK Marine Strategy Part 1 2019 were developed and produced in collaboration with other contracting Parties of the OSPAR Convention for the Protection of the North East Atlantic. In 2017 OSPAR Published its Intermediate Assessment (IA2017). The IA 2017 further develops OSPAR’s understanding of the marine environment of the North-East Atlantic and its current status. It demonstrates OSPAR’s progress towards realising its vision of a clean, healthy and biologically diverse North-East Atlantic, used sustainably. IA2017 follows on from OSPAR’s previous holistic assessment, the OSPAR Quality Status Report in 2010 (QSR2010) and in 2000 (QSR2000).
JNCC continues to develop and pilot tools for the assessment of marine habitats and species in offshore waters to improve the quality and transparency of our offshore MPA assessments, and contribute to the monitoring of marine biodiversity in UK waters. These tools cover methods for producing interim assessments of site features and their responses to pressures, as well as developing more robust indicators for determining condition of the features.
