Summary

 

Last updated October 2017

 

Information for this site summary was adapted from JNCC’s scientific advice to Defra on Western Channel MCZ and incorporates any further information gathered since this document was produced. Please refer to this document in the relevant documentation section for further details and information sources.

 

Site overview

Western Channel MCZ is situated approximately 54 km off the south coast on England to the south-east of the Lizard Peninsula. The site is an area of continental shelf that is predominantly sandy with a mixed distribution of coarse and mixed sediments across the site extent.
The site protects subtidal habitats that are representative of offshore habitats in UK waters. This includes the protection of almost 1440 km2 of Subtidal coarse sediment, as well as over 150 km2 of Subtidal sand. The acoustic signature from survey shows the presence of sand waves throughout the site known as Barchan dunes. These crescent-shaped sand dune produced by the action of wind predominately from one direction.  These habitats support a range of animal species including segmented worms, sponges, molluscs and echinoderms, including sea urchins and starfish. Cnidarians, such as anemones, are also present alongside a variety of crustaceans and fish species, including the small spotted cat shark (Scyliorhinus canicula) and Angler fish (Lophius piscatorius).

Further detail on the evidence for this MCZ can be found on the Evidence tab.

Conservation Objectives

 

Supplementary Advice on the Conservation Objectives (SACO)

The Conservation Objectives set out the broad ecological aims for the site. JNCC provide 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 JNCC at: offshorempas@jncc.gov.uk.

 

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 consider 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: Management is in development

 

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. Fisheries management is under discussion between the Marine Management Organisation, Defra and JNCC.


This site forms part of the UK's contribution to the OSPAR commissions network of MPAs, Europe’s Natura 2000 network and the Emerald network established under the Bern Convention. As the UK is a signatory to the OSPAR commission, JNCC are committed to ensuring that the OSPAR MPA network is ‘well-managed’ by 2020.

JNCC consider ‘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 sites 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 Western Channel MCZ around each of these four stages in the MPA management cycle:

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 tab.
  • JNCC are in the process of improving our MPA conservation advice packages. Further information is available on our conservation advice pages.
  • Spatial information on the presence and extent of the protected feature of this MPA is available via JNCC’s MPA mapper.
  • JNCC are in the process of developing downloadable MPA data packages where appropriate permissions to share datasets are in place.

 

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 indicate that there is mobile demersal gear and potting activity occurring within the MCZ.
  • This MCZ falls outside the UK’s 12 nautical mile limit and is to be exclusively managed under the EU Common Fisheries Policy (CFP). In accordance with Article 18 of the revised CFP, requests for management will be developed jointly between the UK Government and any Member States with a direct management interest in the area affected. The Marine Management Organisation (MMO) are the lead authority regarding the implementation of, and compliance with, any measures to manage fishing activity. Further information on progress is available via MMO webpages.

Licensable activities

  • Licensable activities such as oil and gas exploration and production do not take place within Western Channel MCZ at present, but any future proposals would be managed in accordance with the clauses set out under Section 127 of The Marine & Coastal Access Act (2009). Under this clause, JNCC have 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 site’s conservation objectives. JNCC consider the existing marine licensing process is sufficient to ensure the management of licensable activities that could take place in the future on the protected features of this MPA.
  • For further information, please see the MMO’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 industries advice webpage

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.

 

Site condition monitoring
Site condition monitoring surveys are yet to take place within this MPA. Further information will be made available under the Monitoring tab in due course.

Progression 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’s protected features have ‘recover’ conservation objectives, 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 under the Assessment tab as it becomes available.


 

 

Monitoring

 

Last updated October 2017

 

MPA Monitoring

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

 

MPA Assessment

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 predefined 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. They include the second cycle of the Conservation Status Assessment reports under the EU Habitats Directive, Charting Progress 2 (CP2) and the OSPAR Quality Status Report (QSR). 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.

Under the UK Marine & Coastal Access (2009), JNCC is required to report to Ministers on the degree to which the conservation objectives of the protected features of Marine Conservation Zones (MCZs) have been achieved.  Every 6 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. 

The assessments of features within MPAs will also feed into six yearly reports on the state of the marine environment under the Marine Strategy Framework Directive (MSFD), which aims to achieve Good Environmental Status (GES) by 2020.
