Special Areas of Conservation (SACs)

  • English

  • All

This spatial dataset contains digital boundaries of Special Areas of Conservation (SACs) in Wales. The EC Habitats and Species Directive came into effect in 1992 with the aim of maintaining a rich variety of wildlife by protecting vulnerable habitats, and the plants and animals they support. The Habitat Directive together with the 1979 Birds Directive will lead to the establishment of a series of sites throughout Europe that will be known as 'Natura 2000'. This represents the cream of European sites and will ensure their survival for future generations. SACs have been designated over a number of years, from 1993 to the present day, and are on-going. These sites have been mapped on paper since the mid 1990s and then there was a major review from 2000 with the 'SAC Moderation Project' when the data was captured digitally for the first time.

Lineage

In 2005 all SACs were re-designated/designated and the number of sites doubled in Wales, so this entire dataset originated as digital data to OS Landline. In 2008 the whole dataset was updated to OS MasterMap (mostly to CCW 2006 OS update). If any underpinning Sites of Scientific Interest (SSSIs) are re-notified the overlying SAC designation will likewise be put to the latest release by NRW of OS MasterMap. With the coming of GIS and its use in government departments and commercial companies mobilising the data in this way, advances the protection of these sites and the efficiency of decision making. This data has been checked by NRW staff. However please refer to the designation map as the legal definitive boundary. Large SACs that have been printed on a smaller scale map than OS Landline, please refer to OS MasterMap edition at time of transposition to view the definitive boundary.
Additional Information

Please refer to EC Habitats and Species Directive 1992 for reasons for capture of original designation. Before Special Areas of Conservation or fully designated they go through a stage of being a cSAC or candidate Special Area of Conservation, these reside in a separate layer. In addition to the NRW has also created a subset of this dataset just showing those which are Marine Special Areas of Conservation, this is available on the marine planning portal.
