Natural England Conservation Advice for Marine Protected Areas
Kingmere MCZ

Natural England guidance

This site collection contains Natural England’s conservation advice for this site. It fulfils Natural England’s responsibility under the Marine and Coastal Access Act 2009, to give advice on how to further the conservation objectives for the site, identify the activities that are capable of affecting the designated features and the processes which they are dependent upon.

Natural England's conservation advice for this site is made up of a number of components. You will need to consider: Additional information for consideration:

Background information and geography

Kingmere lies between 5 and 10 km offshore from the West Sussex coast, between Worthing and Littlehampton.

Kingmere MCZ contains excellent examples of rocky habitat and subtidal chalk outcropping reef systems. These rocky habitats support a wide range of marine life. This site is one of the most well-known for spawning black seabream and may be one of the most important spawning sites within UK waters.

The site contains two marine Sites of Nature Conservation Interest (SNCI): Kingmere Rocks and Worthing Lumps. These are non-statutory sites identified for local conservation and geological value by the local authorities and Sussex Seasearch.

Given the considerable habitat variation and complexity within the eastern English Channel marine environment, some of the habitats require a more detailed specific description than those broadly defined for the original MCZ feature list. At this MCZ, this relates to the moderate energy infralittoral rock and thin mixed sediment.

Site maps

Use the MAGIC website to see site maps, including habitats, species and other marine designations.

These maps are based on best available evidence, there are some caveats associated with the maps on MAGIC.

The black seabream nesting area data has been provided by Lafarge Tarmac Marine Ltd; Hanson Aggregates Marine Ltd; and Cemex UK Marine Ltd. This information is a result of targeted survey work between 2002 and 2013. It indicates the best-known locations of nesting activity to date. However it should not be considered a definitive record of all nesting activity or of the potential supporting habitat for nesting activity within the Kingmere MCZ.

Conservation objectives

The site’s conservation objectives apply to the Marine Conservation Zone and the individual species and/or habitat for which the site has been designated (the “Designated features” listed below);

There are two conservation objectives of the zone:

The first conservation objective of the zone is that the protected habitats (listed below):

  1. are maintained in favourable condition if they are already in favourable condition, or
  2. be brought into favourable condition if they are not already in favourable condition.

For each protected habitat feature, favourable condition means that, within a zone both:

  1. its extent is stable or increasing
  2. its structure and function, its quality, and the composition of its characteristic biological communities (including diversity and abundance of species forming part or inhabiting the habitat) are sufficient to ensure that it remains in a condition which is healthy and does not deteriorate.

The second conservation objective of the zone is that, in relation to black seabream:

  1. the habitat used by individuals of that species for the purposes of spawning (spawning habitat); (a) are maintained in favourable condition if they are already in favourable condition, or (b) be brought into favourable condition if they are not already in favourable condition.
  2. the population (whether temporary of otherwise) of that species occurring in the zone be free of the disturbance of a kind likely to significantly affect the survival of its members or their ability to aggregate, nest, or lay, fertilise or guard eggs during breeding.

For the spawning habitat of black seabream within the zone, favourable condition means that the habitat is of sufficient quality and quantity to enable individuals of this species using the habitat to survive, aggregate, nest, lay, fertilise or guard eggs during breeding.

Any alteration to a feature brought about entirely by natural processes is to be disregarded when determining whether a protected feature is in favourable condition.

This should be read in conjunction with the accompanying supplementary advice section, which provides more detailed advice and information to help achieve the objectives set out above, including which attributes should be maintained and which restored.

Designated features:
  • Black seabream, Spondyliosoma cantharus
  • Moderate energy infralittoral rock and thin mixed sediment
  • Subtidal chalk

Feature Condition

In 2016, Natural England trialled and rolled out a new Marine Protected Area (MPA) condition assessment methodology that provides robust results and information on the condition of marine features designated within MPAs in England. With guidance from National teams and using all available evidence and condition monitoring data, Area Teams conduct these assessments following a standardised approach that assesses if the feature and sub feature conservation targets set for each MPA have been met.

To date, condition assessments have been completed for a number of features in a range of marine Special Areas of Conservation (SACs) by the National and Area Teams. Further marine habitat features in SACs and other MPAs will continue to be assessed in the future. The new method can now also be applied to complete habitat and species condition assessments for other MPAs in England, whilst still meeting the different processes in place to report on the results of condition of features in Marine Conservation Zones (MCZs) and Special Protection Areas (SPAs). Different processes are currently in place to decide and report on the condition of non-marine habitat and species features of SACs.

The main part of the assessment process is directly undertaken and stored here on Natural England’s Designated Sites View. The details for the most recent assessments of this site can be found here.

Management measures

If you are carrying out an environmental assessment, planning an operation or assessing an operation or proposal, it is important to consult with the following organisations where applicable. To find out if any management measures, byelaws or other restrictions apply to your activity see the management measure page or you can use the following links for more information.

The Marine Management Organisation license, regulate and plan marine activities in the seas around England and Wales so that they’re carried out in a sustainable way.
Environment Agency are responsible for regulating major industry and waste, water quality and resources, fisheries, inland river, estuary and harbour navigations, conservation and ecology.
Offshore Petroleum Regulator for the Environment and Decommissioning (OPRED) regulates oil and gas, CCS and gas storage activities in the marine environment.
