This table provides metadata for the actual indicator available from UK statistics closest to the corresponding global SDG indicator. Please note that even when the global SDG indicator is fully available from UK statistics, this table should be consulted for information on national methodology and other UK-specific metadata information.
Proportion of important sites for terrestrial and freshwater biodiversity that are covered by protected areas, by ecosystem type
Data is reported for both subindicators (1) Average proportion of Terrestrial Key Biodiversity Areas (KBAs) covered by protected areas (%); (2) Average proportion of Freshwater Key Biodiversity Areas (KBAs) covered by protected areas (%)
|Unit of measurement||
Terrestrial - identified by undertaking a spatial overlap between Key Biodiversity Area polygons and an ocean raster layer, Key Biodiversity Areas were classified as a terrestrial Key Biodiversity Area where ≤95% overlap occurred with the ocean layer. Thus, some sites were classified as both terrestrial and marine.
Freshwater - sites were classified as freshwater Key Biodiversity Areas if the resident species for which they were identified were documented in the IUCN Red List as dependent on ‘Inland Water’ systems.
Key Biodiversity Area - sites contributing significantly to the global persistence of biodiversity as described by IUCN (2016). Key Biodiversity Areas (KBAs) include 1) Important Bird and Biodiversity Areas (IBAs), and 2) Alliance for Zero Extinction sites.
Important Bird and Biodiversity Area (IBA) - (IBAs) are sites of importance for threatened species, restricted range species, biome-restricted species or congregatory species. IBA criteria have been defined at global, regional and EU scale.
Alliance for Zero Extinction sites - Sites that contain '95% or more of the remaining population of one or more species listed as endangered or critically endangered on the IUCN Red List of Threatened Species'. There are currently no such sites in the UK.
Protected area - Protected areas include Nature Reserves, National Parks, Areas of Outstanding Natural Beauty (AONB), Sites of Special Scientific Interest (SSSI), Heritage Coast, and National Scenic Areas. For the full list of designations please see Protected Planet. Protected areas are taken from the World Database of Protected Areas (WDPA). Note that the data presented here do not include any Marine Protected Areas (MPAs).
No calculations were performed in the data acquisition of this indicator as appropriate data was readily available in the final format specified by this indicator. For detail on calculations made prior to acquisition see the global metadata.
Trends in both series are driven by change in the area covered by Protected Areas. There is no change in the area coverd by Key Biodiversity Areas over the time period presented
The Integrated Biodiversity Assessment Tool (IBAT) reports international data for this indicator. UK-level data can be found in the Country Profiles, with further information included on Protected Area designation types, and IUCN management categories. IBAT gives the option to view individual KBAs and Protected Areas on a map - by clicking on KBAs, and then on the name of the area the user is given more information on why it is classed as a KBA, and the species present. By clicking on Protected Areas, the user is given more information on the terrestrial and marine protected areas which can be visualised and downloaded from Protected Planet.
The UK Biodiversity Indicators have related indicators for the UK - C1 'Protected Areas' includes 'Total extent of protected areas on land' (C1a), and 'Condition of areas/sites of Special Scientific Interest' (C1c). The Outcome Indicator Framework for the 25 Year Environment Plan includes interim indicator D2 'Extent and condition of protected sites – land, water and sea', taken from the England biodiversity indicators. More information on D2 is presented in the Outcome Indicator Framework for the 25 Year Environment Plan - 2021 Update.
Data follows the UN specification for this indicator. This indicator has been identified in collaboration with topic experts.
