Summary

Last updated: October 2017

Information for this site summary was adapted from JNCC’s Relevant Documentation on this site and incorporates any further information gathered since these documents were produced.

 

Site Overview

North-West of Jones Bank MCZ is situated approximately 165 km offshore from the south-west of England. The site covers 399.14 km2 of continental shelf, of which 339.74 km2 consists of Subtidal mud, contributing one of the largest areas of this habitat amongst all designated MCZs.

The seabed in North-West of Jones Bank MCZ comprises a variety of broad-scale habitats such as Subtidal sand, Subtidal mixed sediments and Subtidal coarse sediment. These habitats are representative of the seabed in UK offshore waters and support a range of species, including polychaete worms, veneroid molluscs and echinoderms such as starfish and urchins. The area however, predominantly consists of Subtidal mud and its component habitat Feature of Conservation Importance; Sea-pen and burrowing megafauna communities. This feature consists of stable plains of fine mud, which provide a suitable habitat for burrowing animals such as Norway lobster (Nephrops norvegicus) and a variety of sea-pens like the slender sea-pen (Virgularia mirabilis) and phosphorescent sea-pen (Pennatula phosphorea) that protrude from the seabed.

North-West of Jones Bank MCZ is situated approximately 132 km north-west from South-West Deeps (West) MCZ, and 240 km north-west of The Canyons MCZ. All of these sites contribute to the connectivity and representativity of seabed features within the Western Channel and Celtic Sea biogeographic area. 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 Designation Order listed in the Relevant Documentation section.

Site area: 399.14 km2. North-West of Jones Bank MCZ is larger in size than the Isle of Wight (380 km2).

Site depth range: North-West of Jones Bank MCZ varies in depth from between approximately 100 m and 200 m.

Charting Progress 2 biogeographic region: Western Channel and Celtic Sea.

Site boundary description: The North-West of Jones Bank is a simple rectangle following North–South and East–West lines. Therefore, the boundary is in accordance with the MCZ Ecological Network Guidance, which advises using a minimum number of simple lines to delineate the site. The Finding Sanctuary Regional MCZ Project recommended North-West of Jones Bank MCZ to Government, which was then advised on by the Statutory Nature Conservation Bodies before being subject to public consultation by Defra, between January 2015 and April 2015.

Evidence

Last updated: October 2017

The full overview of the various data used to support site identification, along with information on confidence in feature presence and extent, is available in the pre-and post-consultation advice for Tranche Two offshore Marine Conservation Zones proposed in 2016. JNCC will be adding relevant survey data for this MPA to its MPA mapper in due course.

Some of the data for this MCZ have 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.

 

Survey and data gathering

  • North-West of Jones Bank and The Canyons MCZs seabed survey (2017) – This survey was a collaboration between JNCC and Cefas. Video, grabs and camera imagery were collected in North-West of Jones Bank MCZ to form the first point in a monitoring time-series, allowing JNCC to monitor the rate and direction of long-term change in subtidal mud and sea-pens and burrowing megafauna communities.
  • North-West of Jones Bank MCZ Verification Survey (2012) – The survey was a collaboration between Cefas and JNCC to collect acoustic and ground-truth data to identify the presence and extent of broad-scale habitats and features of conservation importance within North-West of Jones Bank MCZ.

 

Data analysis reports

  • North-West of Jones Bank MCZ community analysis (2016) – Biotope classification using benthic community statistical analysis of data gathered to provide evidence to underpin the MCZ designation. The analysis supports the presence of subtidal coarse sediment, subtidal sand and subtidal mud. The analysis also supports the presence of sea-pen and burrowing megafauna communities
  • North-West of Jones Bank MCZ Post-survey site report (2015) – Data from the 2012 verification survey have been analysed by Cefas. The analysis confirms the presence of subtidal coarse sediment, subtidal sand and subtidal mixed sediments. The analysis also identified the presence of an additional broad-scale habitat, subtidal mud, and a Feature of Conservation Importance (FOCI), Sea-pen and burrowing megafauna communities.
  • British Geological Survey Seabed Sediments Data Points Map – Particle Size Analysis of historical data was used to identify habitat type and converted to the EUNIS broad-scale habitats by JNCC. The data suggest subtidal coarse sediment, subtidal sand, subtidal mud and subtidal mixed sediments all occur within the site.
  • EUSeaMap (2016) – Provides supporting information on the presence and extent of subtidal course sediment, subtidal sand, sublittoral mud and subtidal mixed sediments from a predictive seabed habitat map of European waters.

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'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.

These documents are available on JNCC's Resource Hub.

Activities and Management

Last updated: October 2017

Management status: Progressing towards being well managed

The vulnerability assessment conducted for this site suggests it is unlikely to be moving towards its conservation objectives, but directed site condition monitoring data are needed to improve our confidence in this assessment. Progress is ongoing with regards to the recommendation of a fisheries management proposal to the European Commission.

This site forms part of the UK's contribution to the OSPAR Commission’s network of MPAs. As the UK is a member of 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 North-West of Jones Bank MCZ around each of these four stages in the MPA management cycle:

 

1. The documentation of appropriate measures

  • The conservation objectives and advice on activities capable of affecting the conservation status of the protected feature 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 that bottom trawling, pelagic fishing and the use of static gear types occur within the site which is potentially damaging to the habitats present at North-West of Jones Bank MCZ.
  • 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 on the Marine Management Organisation's webpages.

Licensable activities

  • Whilst licensable activities such as oil and gas exploration and production do not take place within North-West of Jones Bank MCZ at present, any future activities would be 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 that 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

Telecommunications cables

  • One telecommunications cable currently crosses through the MPA.
  • 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 license beyond 12 nautical miles.
  • 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.

Ministry of Defence (MoD) activity

  • The MCZ is within a MoD exercise area and MoD activities are known to take place in the water column above 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.

Shipping

  • Under international law, ships have a right of passage at sea including in areas designated as MPAs (unless management specifies the restriction of ship transiting as outlined through an International Maritime Organisation measure). The pressures associated with shipping activity within North-West of Jones Bank MCZ are not considered likely to impact the protected features of the site.

 

3. Site condition monitoring

Site condition monitoring surveys are yet to take place within this MPA. Further information will be made available in the Monitoring section in due course. A summary of our existing knowledge base for this site is provided in the Evidence section.

 

4. Progression 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 ‘recover’ conservation objective based on a vulnerability assessment that examined exposure to activities associated with pressures to which the protected features of the site are considered sensitive. This suggests the site is unlikely to be moving towards its conservation objectives but site condition monitoring 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.
