4.1 General site character

Habitat class % Cover

Total Habitat Cover


Other Site Characteristics

Situated on the south Wexford coast, site comprises a large, shallow (1-2 m) sedimentary lagoon separated from the sea by a long (5-6 km) gravel/sand barrier. At present there is no natural outlet to the sea and the lagoon drains through installed pipes. The pipes are not of sufficient capacity to prevent winter flooding. Salinity is generally low but rises as water levels fall in summer. The lagoon bed sediments are colonised by halophytic vegetation, especially Salicornia spp. Substantial areas of the lagoon are now dominated by swamp vegetation and there are also marginal areas of wet grassland. The gravel/sand barrier is mostly covered by a sand dune system. Surrounding land is low-lying and used for agriculture, both pasture and arable.

4.2 Quality and importance

Site provides an excellent example of a shallow, generally oligohaline, percolation lagoon. One of the largest and best examples of its type in the country and one of the largest lagoonal habitat of any type in the country. Flora and fauna diverse and typically brackish. Has the Red Data Book charophyte Chara canescens and several rare lagoonal fauna specialists (Notonecta viridis, Enochrus halophilus, Ochthebius marinus). The gravel/sand barrier is an important geomorphological feature and has the very rare and Red Data Book species Otanthus maritimus. Dunes are of moderate quality. Important for waterfowl in autumn and winter. Has nationally important populations of eight species, and particularly important for Anas strepera and Anas acuta (11% and 14% of respective national totals). Used by the Annex I Bird Directive species Cygnus cygnus and Pluvialis apricaria and occasionally by Cygnus columbianus bewickii.
