Ballymaclary Nature Reserve
Grid Reference C700365
This reserve contains some dune slack communities, which are few in number in Northern Ireland.
There is one particular moss, Rhytidium rugosom, which flourishes in these dunes that has not been found anywhere else in Ireland.
Low lying dune slacks periodically flooded in winter have a rich and varied range of summer flowering plants, including large numbers of the otherwise rare marsh helleborine.
Around Ballymaclary the shoreline is currently eroding but this is part of the overall cycling of sediments in the Magilligan / Tunns Bank system.
