Murlough SAC
- Habitat,
- Marine
The terrestrial element comprises the major dune systems of Murlough and Ballykinler, together with the relatively intact low dunes and ridges within Royal County Down golf club. These host a range of dune communities, but most important, are the dune heath and grey dune grasslands. The site is particularly important for the population of marsh-fritillary butterfly. The Inner Bay supports limited saltmarsh. The site is of international importance for earth science with contemporary coastal processes, including a classic ridge and runnel beach form, and associated dune forms, together with features important to understanding post-glacial sea-level history including the important underlying gravel series. The dunes host important fossil soil horizons with associated archaeological artefacts.
