Other Site Characteristics

This small machair/wetland site is located in the south-west of Co. Galway, 6 km west of Roundstone village. The underlying geology of the site consists of granite. Most of the bedrock, however, is masked by a cover of sand and thin organic soils. In addition to the machair interest, the site contains areas of freshwater marsh, freshwater lake, grassland and heath. The site can be divided into two contrasting halves, an exposed coastal half dominated by wind-blown sand and a more sheltered half, dominated by lakes and wetlands. The sheltered nature of the wetland areas and their close proximity to the coast is partially responsible for the extensive development of freshwater marsh vegetation along the margins of Loughs Namanawaun and Murvey.

4.2 Quality and importance

This site is important because of the presence of the priority Annex I habitat machair, though the quality of the habitat has been reduced by erosion by the sea and intensive grazing. Associated with the machair is a recently discovered population of the Annex II liverwort Petalophyllum ralfsii. Eriophorum gracile, a Red Data Book and legally protected plant species, has been recorded recently from both Lough Namanawaun and Lough Murvey. These small but productive coastal lakes provide very good examples of wetland succession.
