UK National Site Network (SAC and SPA): site summary details spreadsheet

This spreadsheet contains the latest UK-wide data gathered as part of the Standard Data Form (SDF) information completed for all sites in the UK National Site Network.  It contains details of all Special Areas of Conservation (SACs) and Special Protection Areas (SPAs) in the UK (note that Gibraltar information is not included in this spreadsheet). The spreadsheet was last updated in March 2026 to ensure consistency across reporting (note the spreadsheet was republished in June 2026 to address some fomatting issues).

The information follows the officially agreed site information format as set out in the Official Journal of the European Union recording the Commission Implementing Decision of 11 July 2011 (2011/484/EU). Whilst the UK no longer submits data to the European Commission, it continues to produce SDFs using the Natura 2000 format.

This spreadsheet is organised in a series of tabs, corresponding to different sections of the SDF. On some tabs, SPA and SAC data are separated, whereas on others they are combined. Where they are combined, there is a column to indicate the type of site (SAC or SPA). All sheets are filterable by Country codes - (E, S, W, NI and O for offshore UK). Lower case "i" indicates that a site is inshore e.g. S(i) for Scotland (inshore). The country code of E, S, W, or NI not followed by "i" indicates it is a terrestrial zone e.g. E for England (terrestrial). Cross border sites are shown via a "_” e.g. E_W for England (terrestrial)/ Wales (terrestrial), S(i)_O for Scotland (inshore)/Offshore UK. The tabs are:

* SAC site details – contains summary information about the SACs themselves, including their size, location and date of designation. This tab contains descriptions of the quality/importance of the site and physical characteristics.
* SPA site details – contains summary information about the SPAs themselves, including a brief description, their size, location and date of classification. Most of the data are sourced from the SDFs, with the exception of the information in the 'overview' and 'local authority' columns. The list includes all classified SPAs. There is also an indication of which sites contain marine components (i.e. can be considered to be part of the Marine Protected Areas Network).
* Admin regions – contains details of the administrative regions for each site using the NUTS Level 2 categories.
* SAC interest features – contains a full listing of all interest features occurring on SACs in the UK. This includes non-qualifying ('D-grade') features that are not a reason for SAC selection at a particular site. Note that a feature may not occur on all parts of a site, especially in the case of large SACs.
* SPA interest features – shows bird data (i.e. the occurrence of each species on each site). The list of species for each site includes only those listed on the SDF (specifically those listed in section 3.2 of the form). Qualifying assemblages are listed in a separate tab. It does not take account of the recommendations published in the SPA Review except where there has been a subsequent legal amendment to the relevant SPA citation.
* Maps – offers a simple mapping facility. If a particular feature or site is selected in the above worksheets using the Autofilter function, a dot map will be displayed showing the location of the site(s).
* Habitat classes – indicates the percentage of each SAC/SPA comprised of certain broad habitat types. These are intended to give a general impression of the character of the SAC. They should not be confused with the Annex I habitats, which are listed in the SAC interest feature worksheet.
* Threats and pressures – lists the positive and negative factors that impact on the site. These data were collated for the first time in the UK as part of the December 2015 submission to the EU.
* Designation type – this refers to a very limited range of National Designations, specifically SSSI (ASSI in Northern Ireland), Marine Nature Reserves and National Nature Reserves.
* Management Body – indicates the appropriate Statutory Nature Conservation Bodies.
* Management plan – indicates whether or not a management plan exists for the site.
