Ardaloedd Cadwraeth Arbennig (ACA)
Mae'r set ddata ofodol hon yn cynnwys ffiniau Ardaloedd Cadwraeth Arbennig (ACA) a ddynodwyd yng Nghymru. Daeth Cyfarwyddeb Cynefinoedd a Rhywogaethau'r Gymuned Ewropeaidd i rym ym 1992 gyda'r nod o warchod bioamrywiaeth trwy ddiogelu amrywiaeth eang o gynefinoedd a rhywogaethau anifeiliaid a phlanhigion. Mae pob ACA, ynghyd ag Ardaloedd Gwarchodaeth Arbennig (AGA) a ddynodwyd o dan Gyfarwyddeb Adar Gwyllt y Gymuned Ewropeaidd i ddiogelu rhywogaethau adar prin a mudol, yn cynnwys rhwydwaith o safleoedd ar draws yr UE a elwir yn 'Natura 2000'. Cynigiwyd y rhan fwyaf o ACA yng Nghymru yng nghanol y 1990au ac fe'u dynodwyd yn ffurfiol yn 2004. Cafodd ACA eu mapio ar bapur yn wreiddiol ond ers tua 2000 mae'r data ffiniau wedi ei gipio'n ddigidol. Mae'r safleoedd ACA a ddangosir yn y set ddata hon wedi cwblhau'r broses gyfreithiol lawn o ddynodi.

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.

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.
