Background information and geography

The North Norfolk Coast SAC has an area of 3,207.37 ha and is located to the east of The Wash embayment on the East coast of England. The Annex I habitats that are marine features of the site include coastal lagoons and Mediterranean and thermo-Atlantic halophilous scrub, both of which are listed as primary reasons for selection of the site. Otter is the only Annex II species listed as a qualifying feature of the site.

Coastal lagoons are a priority habitat and are relatively uncommon in the UK. They can increase biodiversity and provide important habitats for breeding and overwintering birds; for this reason much of the coastal lagoon resource within the UK has been included in the SAC series.

The North Norfolk Coast SAC was designated for percolation lagoons and together with the Orfordness-Shingle Street SAC and the Benacre-Eastern Bavents SAC, forms a significant part of the percolation lagoon resource in this part of the UK. Percolation lagoons are separated from the sea by shingle banks, but allow sea water to enter by percolating through the shingle or by over-topping the bank (eg in storms). Salinity in the lagoons is maintained by this percolation of seawater through the beach or dune barrier with the substrate located at the bottom of the lagoons being generally made up of shingle covered by mud.

This site is particularly important for Mediterranean and thermo-Atlantic halophilous scrubs, as it is the only area where all the typical plant species for this habitat occur. The scrubby, salt-tolerant vegetation often develops in the uppermost levels of the saltmarsh, where there is saltmarsh to dune transition and also where dunes overlay shingle. Vegetation here is generally dominated by scattered shrubby bushes with patchy herbaceous plants and bryophytes.

The SAC is also important for otters. These animals became extinct in Norfolk in the 1980’s but after a re-introduction, sightings of coastal otters have increased with them most likely using the inland areas for freshwater and using the coastline for hunting.

The pursuit of traditional activities, including those of common rights, and those embraced by the Longshore Economy such as samphire gathering, bait digging and wildfowling is widely recognised by Natural England and the other relevant authorities as a particularly important aspect of the local cultural heritage and economy at this site. Such activities are generally seasonal in nature, localised in their occurrence, employ traditional methods and place a strong emphasis on the principles of sustainability. The Wells, Boston and King’s Lynn Advisory Groups’ understanding of the levels of these activities since Regulation 33 advice was published in 2000, is that they have had no adverse effect on the site's condition and that there is evidence that some activities, particularly reed cutting and mussel cultivation, can make a positive contribution to the favourable condition of the site. It is thus agreed that such activities, including all the Common Rights on the north Norfolk coast between Holme and Holkham, as currently and historically practiced under law relating to Commons and carried out using traditional methods, are compatible with the need to maintain condition of the site’s features.

As part of the development of the management scheme for the European marine site, the relevant authorities, advisory groups and local communities will need to continue to work together, to obtain a better shared understanding of the benefits and deficits of these activities as they change over time. This will provide an essential mechanism for determining whether fluctuations in these activities may have the potential to adversely affect the interest features of the site.

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.

There are some instances where the feature, subfeature or supporting habitat name varies on MAGIC from the conservation advice. The alternative names are listed on

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 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.
