Annex I habitats that are a primary reason for selection of this site
2130 "Fixed coastal dunes with herbaceous vegetation (""grey dunes"")" * Priority feature
Bann Estuary in Northern Ireland contains a series of three sand dune systems, which are part of the same physiographic unit. The most morphologically diverse are at Portstewart, where transverse dune ridges are up to 30 m high. ‘Grey dune’ is the most extensive vegetation community and is dominated by marram Ammophila arenaria and red fescue Festuca rubra. Short sward communities within this are characterised by a floristically diverse range of herbs and in places lower plants. Lady’s bedstraw Galium verum, wild thyme Thymus polytrichus and wild pansy Viola tricolor are widespread.
