Hatton Bank MPA

 

Status: Candidate Special Area of Conservation (cSAC)

Hatton Bank is a large volcanic bank, situated in the Atlantic North-West Approaches, towards the western extent of the UK Continental Shelf. It is an elongate, arc-shaped bank, stretching nearly 500km in length and rising up to 1 km above the surrounding seafloor.

 

The vast size and topographic complexity of the Hatton Bank supports a wide diversity of biological communities, each associated with different seafloor structures and substratum types. The bedrock, cobbles and coral rubble are home to rich coral gardens and deep-sea sponge aggregations, and the distinct pinnacles and mounds support elaborate cold-water coral reefs.

Site overview
Hatton Bank is a large volcanic bank, situated in the Atlantic North-West Approaches, towards the western extent of the UK Continental Shelf. The water depth across the bank ranges from less than 500m on the northern part of the bank, to over 1000m at the base. At its south-eastern tip, an igneous complex called Lyonesse forms a topographic high, rising to 520m below sea level, some 350m shallower than the surrounding bank.

The vast size and topographic complexity of the Hatton Bank supports a wide diversity of biological communities, each associated with different geomorphological structures and substratum types present on the bank. Much of the seabed on Hatton Bank comprises coarse sandy sediment; however the bank also supports extensive areas of bedrock reef (particularly on the ridges along the top of the bank), as well as many areas of stony reef. Iceberg ploughmarks, a variant of stony reef that are shaped by the movement of icebergs during the last ice age, have also been recorded within the cSAC.

The hard substrata provided by the boulders, cobbles and bedrock reef support a rich diversity of species, including scleractinian corals, stylasterids (‘lace’ corals), antipatharians (‘black’ corals), soft corals, cup corals and gorgonian sea fans; as well as a range of sponges; sessile sea cucumbers; anemones and brachiopods. The presence of Coral gardens has been confirmed on the bedrock, cobbles and coral rubble on Hatton Bank within the cSAC boundary. Deep-sea sponge aggregations have also been confirmed within the site boundary, comprising high densities of vase-shaped glass sponges. Both of these habitats are considered to be Threatened and/or Declining across the North-east Atlantic by the OSPAR Commission.

Primarily found in the southern region (including Lyonesse) and across the north-west Hatton Bank outcrops, the elaborate cold-water coral reefs are associated with pinnacles and mounds, and can be tens of metres in height and hundreds of metres wide. Their intricate structure is formed by both the Lophelia pertusa and Madrepora oculata species, which, in association with the surrounding dead coral framework, support a range of associated fauna. Lophelia pertusa reefs are also considered to be Threatened and/or Declining across the North-east Atlantic by OSPAR. Further detail on the evidence for this cSAC can be found on the Evidence tab.

 

Site location: Coordinates for this cSAC can be found in the Natura 2000 Standard Data Form listed in the Relevant Documentation.

Site area: 15,694 km2.

Site depth range: The shallowest area of the MPA is approximately 460m below sea level, and the deepest section is 1740m below sea level.

Charting Progress 2 Biogeographic Region: Atlantic North-West Approaches, Rockall Trough and Faeroe/Shetland Channel.

 

Site boundary description
Due to the size of the Hatton Bank and the limited number of scientific surveys undertaken in this area, survey data is not comprehensive across the full extent of the site. However, JNCC consider that there is sufficient up to date information with which to delineate a scientifically valid boundary that encompasses the known records of the reef feature on Hatton Bank. Data to inform the boundary is derived from a number of different sources, as summarised under the Evidence tab.

 

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 Hatton Bank SAC Selection Assessment Document.  JNCC will be adding relevant survey data for this MPA to the JNCC interactive MPA map in due course.Some of the data for this cSAC 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 feature within the site.

 

Survey and data gathering

  • ECOVUL/ARPA program (2005 – 2007) - Led by the Spanish Instituto Español de Oceanografía (IEO), this work aimed to investigate vulnerable deep‐sea habitats between depths of 1000-1500m below sea level on the western and north-western flanks of the bank. Both multibeam survey and high resolution seismic profiles of large areas of the western flank of the bank were conducted, supported by biological survey in the form of bottom trawl, dredge and box core sampling.

Activities and Management

 

Last updated: October 2017

 

Activities and Management

Management status: Progressing towards being well managed

 

The full extent of Hatton Bank cSAC has been closed to bottom fisheries since 2013, but directed site condition monitoring data is required to conclude with confidence the degree to which the site is moving towards or achieving its conservation objectives.

 

This site forms part of the UKs contribution to the OSPAR commissions network of MPA's, 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 Hatton Bank cSAC around each of the 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 JNCCs 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 feature of the site. At the time of writing, there were no known activities taking place within the MPA.

 

Fisheries

Licensed activities

  • No licensable activities are currently known to take place within this MPA.
  • Should interest be expressed by developers in the future, a legal framework for consenting licensed activities would need to be developed.
  • Further information on JNCCs role in the provision of advice for licensed activities in the UK offshore area is available on JNCCs offshore industries advice webpage.

 

Site condition monitoring

Fishing vessel monitoring data is used to monitor compliance with the management measure in place. 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.

 

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 will be provided under the assessment tab 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 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.

 

Every six years, Member States are required under Article 17 of the EU Habitats Directive to report on the Conservation Status of Annex I habitats and Annex II species on the Habitats Directive. The assessments should consider the habitat or species both within the Natura 2000 network and in the wider sea. The latest report was submitted by the UK in 2013 and provided a second assessment of the conservation status of relevant habitats and species within UK marine waters during 2007-2012. The next report is for the period 2013-2018 and is due in 2019; information on the condition of features within SACs will make a contribution to this report. 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.
