UK Biodiversity Indicators 2019. Indicator C1 – Protected areas 2019

Corporate UK Biodiversity


These documents support response indicator: C1. Protected areas. The documents include a fiche, datasheet and technical background document.

This indicator shows the extent of UK protected areas both on land and at sea. The two extent measures are a calculation of the net (non-overlapping) extent of protected areas using mean high water as the boundary between the on-land and at-sea measures.

The indicator also shows the condition of terrestrial and coastal features on Areas or Sites of Special Scientific Interest (A/SSSIs). A/SSSIs are designated for their ‘features’ – habitats or species which give them their scientific interest. Each country in the UK assesses the condition of features and reports either the area or the number of features in favourable or unfavourable-recovering condition. These assessments are converted to percentages in this indicator, to allow them to be combined, but the percentage does not equate exactly to the area that is favourable or unfavourable-recovering.

The UK indicators were comprehensively reviewed during 2011 and 2012 to ensure they continued to be based on the most robust and reliable available data; and remained relevant to the new international goals and targets. Since then the indicators have been refined to improve their relevance/quality, and new indicators developed to fill gaps. In this version of the publication as many as possible of the indicators have been updated with new data. In some cases, however, development work is ongoing, and where this is the case, the work to develop them has been described briefly.
