Summary

Last updated: October 2017

Information for this site summary was adapted from documents listed in the Relevant Documentation section and incorporates any further information gathered since these documents were produced.

 

Site overview

Swallow Sand MCZ is located in the northern North Sea region, approximately 100 km offshore from the Northumberland coast. Subtidal sand is the most abundant feature, with evidence of patches of coarse and mixed sediments as well as mud.  It is the largest site designated in the first Tranche of MCZs, with depths ranging from approximately 50 m to 100 m and a drop down to 150 m in the channel described as Swallow Hole Glacial Tunnel Valley, situated in the north-west corner of the site.

This sediment habitat is characteristic of those found in offshore waters deeper than 30 m, experiencing low tidal stress and constituting a relatively stable habitat that supports a diverse range of marine flora and fauna due to the low energy environment, which is illustrated in the EUSeaMap 'energy due to currents' layer. Following the 2012 MCZ site verification survey, analysis was completed by the British Geological Survey (BGS) and Seastar Surveys Ltd in 2014, in order to further quantify feature extent and assign biotopes to the site. 

The three main elements of the site are sand, coarse sediment, and mud.  The analysis resulted in approximate proportions of 80% sand, 12% mud and 8% gravel.  The community analysis assigned biotopes to the features within the boundary. Four EUNIS Level 3 biotopes were established as well as four EUNIS Level 4 sub-biotopes. A newly established biotope was also described including Ditrupa arietina, an annelid worm found in samples across the site. Further detail on the evidence for this MCZ can be found in the Evidence section.

Site location: Co-ordinates for this MCZ can be found in the Site Summary Document, listed in the Relevant Documentation section.

Site area: Swallow Sand MCZ is a relatively large site in terms of MCZ designations, with an area of 4,746 km2. This is approximately the same area as that of its neighbouring county, Northumberland.

Site depth range: Depth range in this MCZ is approximately 50–150 m (within the Swallow Hole Glacial Tunnel Valley feature) below sea-level.   

Charting Progress 2 Biogeographic Region: Region 1 – Northern North Sea.

Site boundary description: The boundary for Swallow Sand MCZ is a simple rectangle, set to include the geomorphological feature 'Swallow Hole' and broad-scale habitats that encompass coarse and sandy sediment ecosystems. The original site initially proposed included over 15,500 km² of subtidal sand, with almost half encroaching on the Dogger Bank SAC. This overlap was deemed unnecessary therefore a significant reduction in size was applied to form Swallow Sand MCZ as it is now presented, no longer encroaching into the Dogger Bank SAC area.

Evidence

Last updated: October 2017

The full overview of the data used to support site identification, along with information on confidence in feature presence and extent is available in JNCC's 2013 Post-Consultation Advice. JNCC will be adding relevant survey data for this MPA to its MPA interactive map in due course. Some of the data for this MCZ has been collected through JNCC-funded or collaborative surveys and some through other means. Data from these surveys provide direct evidence confirming the presence of the protected features within the site.

Conservation Advice

Last updated: March 2018

A period to comment regarding a change in the General Management Approach for Subtidal sand within Swallow Sand MCZ was run between 23rd October and 4th December 2017. JNCC produced a summary of the response to comments received during this period, which is available in the following paper:

Defra has reviewed the advice provided by JNCC and confirmed the formal change in the Subtidal sand General Management Approach from 'Recover' to 'Maintain' within Swallow Sand MCZ. Please note: a GMA of Maintain does not preclude the need for management now or in the future. Please contact JNCC for further information.

Updated formal conservation advice is now available for this MPA.  Further information on the approach used to develop this advice is available on the 'Conserving MPAs' webpage 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 MCZ 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).  

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: June 2017

Management status: Progressing towards being well managed

Progress is ongoing with the recommendation of fisheries management proposals and ongoing site condition monitoring work will be required in order 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. 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 Swallow Sand MCZ 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 features of this site are available in 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.

Fisheries

  • Vessel monitoring data indicates there are various types of demersal trawling occurring within the MCZ. Effort is concentrated in the north-west corner around the area identified as mud habitat. Some pelagic fishing is known to occur within the site, but the features of the site are not considered sensitive to fishing activity with no bottom contact. UK and non-UK registered vessels have been active in the area. 
  • The Marine Management Organisation (MMO) is the lead authority regarding the implementation of, and compliance with, any measures to managing fishing activity. Further information on progress is available via the MMO's MPA strategic management table

Licensable activities

  • There are three dormant pipelines and three oil wells within the boundary of Swallow Sand MCZ.
  • Licensable activities such as oil and gas exploration and production taking place or that may take place within this MPA are managed in accordance with the clauses set out under Section 127 of the Marine & Coastal Access Act (2009). Under this clause, JNCC has a statutory responsibility to advise the regulator on developments that are capable of affecting (other than insignificantly) the protected features of the MPA and that may hinder the achievement of the sites conservation objectives. JNCC considers the existing marine licensing process is sufficient to ensure the management of licensable activities taking place, or that could take place in the future, on the protected features of this MPA.
  • For further information please see The Marine Management Organisation's guidance on marine conservation zones and marine licensing.
  • Further information on JNCC's role in the provision of advice for licensed activities in the UK offshore area is available on JNCC's offshore industry advice webpages

Shipping

  • There is a low density of commercial shipping and cruising routes in this area and due to its offshore location, vessel anchorage is unlikely.
  • Under international law (UNCLOS, Article 17), ships have a right of innocent passage at sea, including in areas designated as MPAs. The pressures associated with shipping activity within Swallow Sand MCZ are not considered likely to impact the protected features of the site.

Military activity

  • There is limited military activity in the south-west corner of the site.
  • The MoD has incorporated all designated MPAs into their Environmental Protection Guidelines (Maritime) and wider Marine Environmental and Sustainability Assessment Tool. These guidelines are used to manage MoD activity to minimise the associated risks to the environment.

 

3. Site condition monitoring

A site condition monitoring survey took place in 2016 to form the first point in a monitoring time series which will be used to determine the rate and direction of change over time in the condition of the protected features of the site. 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 are available to determine whether the MPA is moving towards or has reached its conservation objectives. The site has a ‘maintain’ conservation objective based on the findings of a vulnerability assessment (exposure to the activities associated with pressures to which the protected features of the site are considered sensitive). This suggests the site may already be achieving or moving towards its conservation objectives. Site condition monitoring time-series data would improve our confidence in this assessment. Further information will be provided in the Assessment section as it becomes available.

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 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 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: October 2017

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
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 Marine Conservation Zones (MCZs) have been achieved. Every six years from 2012, the Marine Act requires a report setting out how MCZs have performed against their conservation objectives, as well as the effectiveness of the network as a whole.

To date, three reports have been published, each setting out progress being made in implementing a Marine Protected Area network, covering the following areas: 

Outputs of assessments that feed into Marine Act reporting also feed into reporting under other obligations.

 

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.
