Stanton Banks MPA

Formal updated conservation advice for the Stanton Banks SAC was produced in March 2018 and is available in the Conservation Advice section below.

Status: Special Area of Conservation (SAC)

 

The Stanton Banks are a series of granite ridges up to 160 m tall that protrude from the seabed, situated south of the Outer Hebrides.

Site

Located south of the Outer Hebrides, the Stanton Banks are a series of granite ridges up to 160 m tall that protrude from the seabed at 190 m deep.

The tops of these ridges are smooth and covered in encrusting species, such as red algae and small sponges. The inter-connecting gullies are filled with rippled coarse shell sand. The rougher sides of the ridges support species such as feather stars, dead man's fingers and hydroids. The smoother lower regions of the banks provide habitat for barnacles, brittlestars, cup-shaped sponges and massive sponges. On the edges of the ridges there are boulders and cobbles covered by coralline algae and keel worms.

More detailed site information can be found in the Summary section below.

Summary

Last updated: October 2017

Information for this site summary was adapted from the SAC selection assessment available in the Relevant Documentation section and incorporates any further information gathered since this document was produced.

 

Site overview

Stanton Banks SAC is located in the Scottish Continental Shelf south of the Outer Hebrides and lies approximately 124 km west of the UK mainland, 43 km west-south-west of Tiree and 83 km north-north-east of Malin Head, Ireland. Surveys of the Stanton Banks reef has shown it to be a rocky landscape with deep gullies. Although the rocky outcrops have been rounded by glacial action, they remain deeply fissured and extremely rugged.

The bedrock outcrops are heavily encrusted with coralline algae, keel worms and brittlestars such as Ophiura albida, with clusters of sponges including cup-shaped axinellid sponges (Axinella infundifiliformis). On the slopes, there is a transition from smooth bedrock to fissured rock outcrops, boulder and cobble with feather stars (Leptometra celtica), dead man's fingers (Alcyonium digitatum) and robust hydroids (Tubularia spp.). The lower circalittoral zone of the Stanton Banks is characterised by smooth, silty bedrock dominated by extensive encrusting coralline red algae, numerous barnacles, brittlestars, small sponge crusts (including Hymedesmia paupertas), cup-shaped axinellid sponges (A. infundibuliformis) and massive sponges (Mycale lingua and Pachymatisma johnstonia). Starfish (such as Luidia ciliaris, Porania pulvillus, Crossaster papposus) and sea urchins (Echinus esculentus) are also common.

Surrounding the Annex 1 rocky reef feature, the banks are fringed with stony reef comprising of boulders and cobbles, graduating into coarse and mixed sediments. Many of the cobbles are covered by encrusting sponges (including Hymedesmia paupertas), hydroids and bryozoans. Crabs (Cancer pagarus) and squat lobsters (Galatheoidea sp.) are also present. There have been reports of cold-water coral at the site, but currently JNCC has no direct evidence to support this. Further detail on the evidence for this SAC can be found in the Evidence section.

Site location: Co-ordinates for this SAC can be found in the Natura 2000 Standard Data Form.

Site area: 817.27 km2, a similar size to the Isle of Mull (870 km2).

Site depth range: The rocky outcrops rise from the seabed at 190 m below sea-level to approximately 30 m below sea-level, encompassing a vertical rise of approximately 160 m. The major gullies within the site are approximately 100 m wide and up to 30 m deep, with other minor gullies typically measuring 20–40 m wide.

Charting progress 2 region: Scottish Continental Shelf.

Site boundary description: The site boundary is a complex polygon enclosing the minimum area necessary to ensure protection of the Annex I habitat. Co-ordinate points have been positioned as close to the edge of the interest features as possible, rather than being located at the nearest whole degree or minute point. The proposed boundary includes a margin to allow for mobile gear on the seabed being at some distance from the location of a vessel on the sea surface. The maximum depth of water around the feature is 190 m; therefore, assuming a ratio of 3:1 fishing warp length to depth, the proposed boundary is defined to include a margin of 570 m from the bedrock reef.

Evidence

Last updated: October 2017

For a full overview of the data used to support site identification, along with information on confidence in feature presence and extent see the Stanton Banks SAC Selection Assessment Document.

Data for this SAC 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

  • RV Scotia Survey (2013) – This survey, led by Marine Scotland, opportunistically collected more acoustic data to improve our understanding of the distribution and extent of the bank features in this site.
  • NLV Polestar C5816 Survey (2012) – The main aim of this JNCC collaboration was to acquire acoustic and ground-truthing data at Stanton Banks SAC to confirm the presence and extent of Annex I stony and bedrock reef. Additional biological data were also collected to develop a baseline for future monitoring.
  • Rockall-North Channel Geophysical CD174 Survey (2005) – This survey was led by the British Geological Survey to collect acoustic data on the topography of the seabed at Stanton Banks and the surrounding area. This survey also gathered geophysical data using a sparker system, a pinger and a precision echosounder.
  • Stanton Banks Surveys (2005 and 2006) – Further survey was undertaken by the North Western Shelf consortium, as part of the Mapping European Seabed Habitats project in 2005 and 2006. This included multibeam survey of three further areas and biological ground-truthing using drop-down video and remotely operated vehicles.
  • Blackstone Surveys (2003 and 2004) – A collaborative survey between JNCC and the Department for Agriculture and Rural Development, Northern Ireland on the RV Lough Foyle. Two areas of Stanton Banks were surveyed acoustically to characterise the topography of the seabed. Biological ground-truthing of these areas using video tows and camera images confirmed the presence of bedrock reef and the biological communities associated with bedrock reef. Additional ground-truthing data were collected in 2004, however, poor weather limited the amount of data collected.

 

Data analysis reports

Further analysis of data gathered as part of the surveys listed above are available via the following reports:

  • Blackstone banks and Stanton Banks habitat mapping (2009) – Provides the results of the analysis of survey data collected during the 2003 and 2004 JNCC collaborative surveys of the Stanton Banks.
  • Report on a survey over Stanton Bank 4 for MESH (2006) – The British Geological Rockall-North Channel survey data were analysed by Stewart and Long (2006) to improve coverage over the site and surrounding area. The geophysical data collected are discussed in the report, and provide more information on the geological history of the site. A new geological feature may also have been identified. 
  • Community analysis – From the analysis of video and stills from the 2006 survey, the following biotopes were found on Stanton Banks:

CR.MCR.EcCr.FaAlCr.Bri (EUNIS A4.2144): Brittlestars on faunal and algal encrusted exposed to moderately wave-exposed circalittoral rock;

CR.MCR.EcCr.FaAlCr (EUNIS A4.214): Faunal and algal crusts on exposed to moderately wave-exposed circalittoral rock and CGS: Cobbles, Gravels and Sands.

Conservation Advice

Last updated: March 2018

Updated formal conservation advice is now available for this MPA.  Further information on the approach used to develop this advice is available on our Conserving MPAs webpage along with a Glossary of Terms used in JNCC conservation advice and a short video explaining how to use the conservation advice packages. 

You must refer to this advice if you:

  • undertake a Habitats Regulation Assessment (HRA) for a plan or project that could impact the site;
  • provide information for a HRA;
  • respond to specific measures to support delivery of 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 February 2018). 

Document Overview
Background Information Explains the purpose of the advice and when it must be referred to.

Conservation Objectives

 

Supplementary Advice on the Conservation Objectives (SACO)

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.

Conservation Advice Statements

These statements provide a summary of the Supplementary Advice on the Conservation Objectives (SACO).

  • Site condition presents our up-to-date understanding of the condition of features within the site;
  • Conservation benefits which the site can provide, these help you understand what is important about the site and why it needs protecting; and
  • Conservation measures which JNCC considers are needed to support achievement of the conservation objectives. These provide clarity around measures needed to support restoration or maintenance of the feature(s) within the site.
Advice on Operations

Provides information on the activities capable of affecting site integrity and therefore achievement of the site’s conservation objectives.

This is a starting point for determining potential management requirements. It does not take into account the intensity, frequency or cumulative impacts from activities taking place. It is simply to advise you of the possible adverse impacts that your activity can have on a MPA’s features.

Use the advice on operations to determine those pressures your activity causes that could harm the habitat and/or species features of the site.

Activities and Management

Last updated: October 2017

Management status: Progressing towards being well managed

Although a baseline monitoring survey took place in 2012, information on the long-term recovery of Annex 1 reef in this site is scarce. Fisheries management measures are in development for the site but not yet implemented, and ongoing site condition monitoring work will be required to conclude with confidence as to 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, Europe’s Natura 2000 network and the Emerald Network established under the Bern Convention. As the UK is a contracting party to the OSPAR Commission, JNCC is committed to ensuring that the OSPAR MPA network is 'well-managed' by 2020.

JNCC considers 'well-managed' to mean the timely progress of an MPA around the 'MPA management cycle'. This involves:

  1. 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.
  2. The implementation of management measures – management actions considered necessary to achieve the conservation objectives of a site.
  3. Site condition monitoring programmes – collecting the information necessary to determine progress towards a site's conservation objectives.
  4. 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 Stanton Banks SAC around each of the 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 feature of the site. The protected feature of the site is considered to be sensitive to pressures associated with fishing and 'licensable' activities.

Fisheries

  • There is evidence of mobile demersal fishing, specifically potting, creeling and seine netting, within the MPA. Both UK and non-UK registered vessels have been active in the area.
  • Marine Scotland is the lead authority regarding the implementation of, and compliance with, any measures to managing fishing activity. Further information can be found on Marine Scotland's webpages.

Licensable activities

  • Whilst 'licensable' activities such as oil and gas exploration and production do not take place within Stanton Banks SAC at present, any future proposals would have to comply with Article 6(3) of the EU Habitats Directive 1992, which is transposed into UK law by The Conservation of Offshore Marine Habitats and Species Regulations 2017.
  • Our conservation advice supports the consents process by setting out the conservation objectives for the protected feature of this MPA and advice on activities that may result in pressures to which the protected feature is considered sensitive.
  • Further information on JNCC's role in the provision of advice for licensed activities in the UK offshore area is available on the JNCC's offshore industry advice webpages.

 

3. Site condition monitoring

A baseline monitoring survey took place in 2012 but site condition monitoring surveys are yet to take place within this MPA. Further information will be made available under the Monitoring section in due course.

 

4. Assessment of progress towards conservation objectives

No long-term condition monitoring data is available to determine whether the MPA is moving towards or has reached its conservation objectives. The site has a ‘restore’ conservation objective based on the findings of a vulnerability assessment which suggests the site is unlikely to be moving towards its conservation objectives. Further information is provided in the Assessment section.

Monitoring

Last updated: October 2017

JNCC is currently leading on the development of a strategy for biodiversity monitoring across all UK waters, to include MPA monitoring. For SACs, 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.

Assessment

Last updated: November 2019

Assessments of the condition of designated features in offshore MPAs are required to report against our legal obligations. Ideally these assessments should be 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 the development of new approaches and tools for the assessment of habitats and species for a variety of national and international status reports.

 

Conservation Assessment Reports

Every six years, Member States of the European Union are required (by Article 17 of the Directive) to report on implementation of the Habitats Directive. The latest report on the Conservation Status of Annex I habitats and Annex II species on the Habitats Directive was submitted by the UK in 2019 and provided an assessment of the conservation status of relevant habitats and species within UK marine waters during period 2013–2018; information on the condition of features within SACs have made a contribution to this report.

 

UK State of the Seas Reports & UK Marine Strategy Part 1

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.
