When undertaking an appropriate assessment of impacts at a site, all features of European importance (both primary and non-primary) need to be considered.
Annex I habitats that are a primary reason for selection of this site
|2130 Fixed 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.|
