and geological SSSIs in Wales - some sites are protected in respect of both types of interest. In addition, two extensive areas are designated as Geoparks; the entire island of Anglesey as 'GeoMôn' in the north and Fforest Fawr within the Brecon Beacons National Park in the south. The Geoparks have a range of roles; conservation and promotion of the two areas' geological heritage are important ones. These objectives are partly achieved through educational and interpretive programmes. 'RIGS groups' are being established in different parts of Wales with the aim of supporting locations designated as regionally important geodiversity sites and assisting in the implementation of Local Geodiversity Action Plans ('LGAPs'). Local authorities and other agencies in the public sector continue to be involved in the acquisition of significant earth heritage sites, their conservation and interpretation. Charities such as Wales' wildlife trusts also have a similar role.
