Other Site Characteristics

The site comprises a relatively small estuarine system in north County Dublin. It receives the flows of the Mayne and Sluice rivers, both of which drain an agricultural / suburban catchment. Much of the estuary is sheltered from the sea by a large sand dune peninsula (now mostly a golf course). Sediments in the inner sheltered areas are mostly muds or muddy sands, often with a high organic content. Towards Portmarnock Point, the sediments are predominantly well-aerated sands. In addition to the intertidal flats and salt marsh habitats, a small area of sand hills and sandy beach at Portmarnock Point is included in the site.

4.2 Quality and importance

Baldoyle Bay is a typical eastern estuarine system with fairly extensive intertidal sand and mud flats which have Zostera spp. It also has good salt marsh fringes where birds roost. The quality of habitats present is variable but generally good. The site supports a good diversity of wintering waterfowl and notably an internationally important population of Branta bernicla hrota. It has nationally important populations of Tadorna tadorna, Anas acuta, Charadrius hiaticula, Pluvialis apricaria, Pluvialis squatarola and Limosa lapponica. At high tide the shallow waters regularly attract species such as Podiceps cristatus and Mergus serrator. Sterna albifrons formerly bred at the site, but not since the early 1990s.
