Other Site Characteristics

The site is located just south of Cahore Point on the north Wexford coast. The area is underlain by rocks of Cambrian age. The site comprises a sand dune system that extends along the coast for over 4 km and which reaches up to 18 m in height. The dunes are backed by extensive areas of polder grassland interspersed by canals and drainage channels. The drainage canals and sluices were installed in the mid 19th century to reclaim wetlands and land that flooded regularly behind the dunes. Seawater may occasionally enter the channels and create brackish conditions. Polder grasslands are included in the site and are valuable for wintering waterfowl.

4.2 Quality and importance

The site has a well-developed dune system typical of the east coast. The dunes display a good zonation, with fixed dunes grading eastwards to marram dominated dunes, embryo dunes and, at the top of the beach, annual driftline vegetation. The northern part of system is subject to erosion from the sea, while active growth is seen in the southern parts. The dunes support two Red Data book plant species, Asparagus officinalis subsp. prostratus, and the hybrid Equisetum x moorei which is confined to the coastline of Wexford and Wicklow. Drainage ditches in the polders support Ceratophyllum submersum, a rare and only relatively recently recorded species in Ireland. The site is of high ornithological importance, having nationally important wintering populations of Anser albifrons flavirostris, Pluvialis apricaria, Anas penelope, Anas clypeata and Vanellus vanellus. It also supports other species in smaller numbers, including Cygnus cygnus and Cygnus columbarius bewickii. Sterna albifrons formerly bred on the beach. Pyronia tithonus occurs near the northern extreme of its Irish range.
