Other Site Characteristics
| The site is located on the western seaboard, approximately 2 km west of the village of Cleggan in Co. Galway. It comprises a range of terrestrial, intertidal and marine habitats. The area is underlain by Omey granite. Aughrusbeg Lough is surrounded mostly by coastal heath with frequent outcropping rock. At its western side it is separated from the sea by a narrow machair plain. Lough Atalia is a tidal lake that is connected to the sea by a narrow intertidal inlet. An area of marine water is included, as well as several small islands (Dog Island, Roeillaun, Gooreen Island). Other habitats include sandy and shingle beaches and rocky shoreline. |
4.2 Quality and importance
| The aquatic vegetation of Aughrusbeg Lake is unusual and has a high conservation value. Overall, it is a very clear, softwater, species-rich lake and, based on current interpretations (O Connor, 2015), is best described as a 3130 Oligotrophic to mesotrophic standing waters with vegetation of the Littorelletea uniflorae and/or of the Isoeto-Nanojuncetea lake. Small patches of the submerged vegetation may conform to 3110, while other areas are dominated by Chara spp. and could be aligned with the hard water lake habitat (3140).
Aughrusbeg Lake was surveyed in 1999 by Cillian Roden in a Heritage Council-funded study, and in September 2017 by Cilian Roden, Paul Murphy and Jim Ryan as part of the NPWS Mixed Najas flexilis lake habitat study. The lake is on granite bedrock and is separated from the sea by a small machair plain, creating sloping granite shores other than at the western end where there is a well-developed sand-shelf. It was ranked as having the highest conservation importance of the 15 coastal lakes surveyed in 1999 (Roden, 1999). The 2017 survey recorded 29 species, including seven Potamogeton species, one Potamogeton hybrid and three-species each of the charophytes Chara and Nitella, in 21 relevés. Euphotic depth was 5.2 m. The sand-shelf at the western end supports a population of what appears to be Chara muscosa (Roden, 1999; Roden et al., 2017). Chara muscosa is closely related to, and may even be an ecologically-induced form of Chara contraria (Stewart, 2017). It was described from Mullaghderg Lough, which remains its only definite world location, but no longer occurs in this site (Roden et al., 2017; Stewart, 2017). |
