SSSIs in the UK are notified using the concept
of an Area of Search (AOS), an area of between 400 km2 (150 sq mi) and 4,000 km2 (1,500 sq
mi) in size. The Areas of Search were conceived and developed
between 1975 and 1979 by the Nature Conservancy Council (NCC), based on regions created by
the Local Government Act 1972. Whereas England had its Areas of Search based
on 46 counties, those in Wales were based on a combination of the counties and smaller
districts. In 1974, Wales was divided into 8 counties,
with 37 districts. The NCC created 12 Welsh Areas of Search;
they mostly follow county borders, but the larger counties (Dyfed, Powys and Gwynedd)
were divided into multiple Areas using district borders. Mid and South Glamorgan were merged into a
single AOS, whilst Llanelli district was included in the West Glamorgan AOS. Due to subsequent local government reorganisation
in the UK since 1972, many counties and districts have been divided, merged or renamed. Using the AOS system alone would make it difficult
to search for individual SSSI citations via the Countryside Council for Wales (CCW) database
without knowing 1972 region divisions. As a result, the CCW groups Welsh SSSIs using
the subdivisions of Wales formed in April 1996 by the Local Government (Wales) Act 1994,
resulting in 22 principal areas. Gwent AOS lies within the counties of Blaenau
Gwent, Caerphilly, Monmouthshire, Newport, and Torfaen. For SSSIs elsewhere in the UK, see List of
SSSIs by Area of Search.==See also==
