Natural England and JNCC Conservation Advice for Marine Protected Areas
Inner Dowsing, Race Bank and North Ridge SAC

Natural England and JNCC guidance

This site collection contains Natural England’s and Joint Nature Conservation Committee (JNCC)'s conservation advice for this site. It fulfils Natural England’s and Joint Nature Conservation Committee (JNCC)'s responsibility under the Conservation of Habitats and Species Regulations 2017 (as amended), and JNCC's responsibility under The Conservation of Offshore Marine Habitats and Species Regulations 2017 to give advice on how to further the conservation objectives for the site, identify the activities that are capable of affecting the qualifying features and the processes which they are dependent upon. The advice reflects the views of both Natural England and JNCC.

Natural England's and JNCC'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

Inner Dowsing Race Bank and North Ridge Special Area of Conservation is located off the south Lincolnshire coast, to the east of Skegness and extends eastwards and north from Burnham Flats on the North Norfolk coast. The site occurs in the approaches to The Wash, and crosses the 12 nautical mile boundary; therefore, lies partly in territorial and partly in offshore waters. Natural England and JNCC have jointly prepared this advice. The site contains sandbanks and Sabellaria spinulosa reefs which meet the Annex I habitat descriptions of “Sandbanks slightly covered by sea water all the time” and “Reefs” respectively. The sandbanks are important headland-associated offshore systems. Water depths are generally shallow and mostly less than 30m deep.

The crests and flanks of the sandbanks are characterised by low diversity communities of polychaete worms (cat worm) and amphipods (shrimp-like crustacean). The troughs which separate the sandbanks contain a diverse mosaic of biotopes on mixed and gravelly sands. Biogenic reef created by the Ross worm Sabellaria spinulosa has consistently been recorded within the site. Aggregations of S. spinulosa provide additional hard substrate for the development of rich epifaunal communities.

The sandbanks provide an ideal spawning and nursery ground for commercially important fish such as the sandeel (Ammodytes sp.) and Atlantic herring (Clupea harengus) while also providing important feeding grounds for lemon sole (Microstomus kitt) and European plaice (Pleuronectes platessa). S. spinulosa reefs provide vital attachment points for both infauna and epifauna, as well as stabilising sediments. They support a variety of bryozoans, hydroids, sponges and anemones as well as the common lobster Homarus gammarus and the commercially exploitable pink shrimp Pandalus montagui. This site is one of only 12 in the UK that contains this form of reef, while extensive sandbanks are only found in the North Sea along the East Anglian coast.

Site maps

Use the MAGIC website and the JNCC Interactive Mapper 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.

Margins are included within the "Sandbanks which are slightly covered by sea water all the time" to account for uncertainty in feature extent of sandbanks that are known to be mobile. The margins can be viewed in the Annex I sandbank layer provided on the JNCC interactive mapper, however these margins are not displayed in Natural England's MAGIC interactive mapper.”

Conservation objectives

The site’s conservation objectives apply to the site and the individual species and/or assemblage of species for which the site has been classified (the "Qualifying features" listed above).

The objectives are to ensure that, subject to natural change, the integrity of the site is maintained or restored as appropriate, and that the site contributes to achieving the Favourable Conservation Status of its qualifying features, by maintaining or restoring:
  • the extent and distribution of qualifying natural habitats and habitats of the qualifying species
  • the structure and function (including typical species) of qualifying natural habitats
  • the structure and function of the habitats of the qualifying species
  • the supporting processes on which qualifying natural habitats and the habitats of qualifying species rely
  • the populations of each of the qualifying species
  • the distribution of qualifying species within the site

Qualifying features

Refer to the site information table above for the list of features within this site.

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

The conservation objectives apply under the Habitats Regulations, and as it is transposed into the offshore area within The Conservation of Offshore Marine Habitats and Species Regulations 2017, must be considered during a Habitats Regulation Assessment, including an Appropriate Assessment.

The conservation objectives and accompanying supplementary advice provide a framework to inform the management and measures needed to conserve or restore the European site, and the prevention of deterioration and significant disturbance of its qualifying features.

Where the objectives are met, the site will be considered to show a high level of integrity, and to be contributing to achieving the aims of the Habitats Regulations.

Supplementary Advice on Conservation Objectives

See supplementary advice on conservation objectives for this site, which aim to describe the range of ecological attributes that are most likely to contribute to a site’s overall integrity.

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.
