Blackrock seashore area and bay are of interest to nature lovers and bird watchers. The seashore and beaches around Blackrock include the inter-tidal mudflats and salt marshes which are an important and integral part of the delicate ecology of Dundalk Bay.
Blackrock has a diversity of habitats including wetlands, salt marshes, river and shallows. It offers food and shelter for a wide variety of species.
Birds winter here in huge numbers (20,000) and include flocks of Greenland White-Fronted Geese, Whooper Swans, as well as Redshanks, Brent Geese and Lapwings. The bay is a designated Special Protection Area (SPA) and a Special Area of Conservation (SAC) under EU law and therefore protected both nationally and at European level.
