Natural England Conservation Advice for Marine Protected Areas
Tamar Estuaries Complex SPA

Natural England guidance

This site collection contains Natural England’s conservation advice for this site. It fulfils Natural England’s responsibility under the Conservation of Habitats and Species Regulations 2017 (as amended), 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.

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

The Tamar Estuaries Complex SPA is composed of extensive intertidal mudflat communities, areas of mixed muddy sediment communities and saltmarsh communities.

These habitats provide important feeding and roosting areas for over wintering avocet and little egret. The mudflats support high densities and variety of invertebrates, a vital food source for birds.

In addition to the designated features the SPA is of importance within Britain and the EU for a range of wildfowl and wader species with peak mean numbers at designation of more than 11,000 overwintering waterfowl. The site is of particular importance for shelduck (Tadorna tadorna), whimbrel (Numenius phaeopus), greenshank (Tringa nebularia) and Mediterranean gull (Ichthyaetus melanocephalus). Other notable species supported by the site include dunlin (Calidris alpine), curlew (Numenius arquata), black-tailed godwit (Limosa limosa) and redshank (Tringa totanus).

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 gov.uk.

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 aims of the Wild Birds Directive, by maintaining or restoring:
  • the extent and distribution of the habitats of the qualifying features
  • the structure and function of the habitats of the qualifying features
  • the supporting processes on which the habitats of the qualifying features rely
  • the populations of each of the qualifying features
  • the distribution of qualifying features 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 condition assessment methodology that provide robust results and information on the condition of marine features within Marine Protected Areas (MPAs). Area Teams conduct these assessments following a standardised approach that assesses if feature- and site-specific targets have been met. Assessments for the first sites have been completed, and several others are currently assessed by the Area Teams.

To date, condition assessments have been carried out for marine habitat features of a number of Special Areas of Conservation (SACs). Marine habitat features in other SACs will be assessed in the future. Different processes are currently in place to report on the condition of features in Marine Conservation Zones (MCZs) and Special Protection Areas (SPAs), and on the condition of non-marine habitat features 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.
