SSSIs cover a wide range of habitats from small fens, bogs and riverside meadows to sand-dunes, woodlands and vast tracts of uplands. Most are in private ownership, although some are owned and managed by local wildlife trusts, or other voluntary conservation bodies. Notification of an SSSI under the Wildlife and Countryside Act 1981 has since been amended by the Countryside and Rights of Way Act 2001, which brought about numerous changes in the way SSSI are notified managed and protected. In order to ensure consistent, favourable long-term management of these sites, Natural Resources Wales (NRW) with landowners have prepared management plans for all SSSI in Wales. Local plan ning authorities are required to consult NRW before allowing any development to proceed that may affect an SSSI. Water, gas and electricity companies must also do the same. SSSIs have been designated, from 1949 to the present day, and are on-going. The data has been held digitally since the mid-1990s. This data has been checked by relevant NRW staff. Please refer to the designation map as the legal definitive boundary. For large SSSIs that were captured digitally and have been printed on a smaller scale map than OS MasterMap, please refer to the OS MasterMap edition at time of capture to view the definitive boundary.

In 2008 the whole dataset was updated to OS MasterMap (mostly to CCW 2006 OS update). This update referred to the original designation maps and all notational descriptions on these maps e.g. “Only the water under the bridges included in the site” OR “SSSI boundary follows, in part the lines of the Mean High and Low Water Marks; both are liable to change.” All new or re-notified sites will be put to the latest release by NRW of OS MasterMap and this information is recorded in the attribute data under the Last_Edited column. As OSMM is updated by the Ordnance Survey it is important to check where boundaries may subsequent ly have moved.
