Special Area of Conservation (SAC)
A Special Area of Conservation is defined under the Habitats Directive. These are sites of Community importance designated by a Member State through a statutory, administrative and/or contractual act where the necessary conservation measures are applied to maintain Favourable Conservation Status.
In the UK The Conservation (Natural Habitats, & c.) Regulations 1994 implement the European Union Directive 92/43/EEC of 21 May 1992 on the conservation of natural habitats and of wild fauna and flora. The Regulations introduce stringent requirements for the conservation of Special Protection Areas and Special Areas of Conservation.
Newborough Warren Ynys Llanddwyn (including most of the forest) is designated SAC for its dune habitats and species.
