Other Site Characteristics

This is a medium sized site rising in height from sea level to 688m. It is dominated, especially at the west of the site, by cliffs which can exceed 300m. Nestling below the cliffs of Croaghaun are five corrie lakes perched at various levels above the sea. Slievemore rises to >650m at the east of the site. Both summits support alpine heath and exposed rock. Wet heath, wet grassland and blanket bog are found on the lower, less steep slopes. The underlying geology is pre-Cambrian schists and gneisses at Slievemore and quartzite at Croaghaun. Land use consists of grazing, peat cutting, quarrying and tourism development. A main road runs parallel to the shore at the south of the site.

4.2 Quality and importance

The site is of immense importance for the occurrence of rare and specialised oceanic bryophytes, most of which are associated with alpine heath. It is one of the best examples of this habitat in the country and covers an area of 297ha. The site also supports a wide diversity of habitats from sea level to >650m. Erica erigena, a plant confined in Europe to Spain, Portugal, Western France and Counties Mayo and Galway in Ireland, has its most westerly location at Lough Nakeeroge (Foss et. al., 1987).
