  • PF: for the habitat types that can have a non-priority as well as a priority form (6210, 7130, 9430) enter "X" in the column PF to indicate the priority form.
  • NP: in case that a habitat type no longer exists in the site enter: x (optional)
  • Cover: decimal values can be entered
  • Caves: for habitat types 8310, 8330 (caves) enter the number of caves if estimated surface is not available.
  • Data quality: G = 'Good' (e.g. based on surveys); M = 'Moderate' (e.g. based on partial data with some extrapolation); P = 'Poor' (e.g. rough estimation)

Other Site Characteristics

Rusheenduff Lough is separated from the Atlantic Ocean by a narrow shingle ridge. The geology of the area is dominated by schist and gneiss. The lake drains a catchment of less than 2 km sq. Two small feeder streams enter the southern part of lake and there is an outflow from the north directly to the sea. It is a shallow lake with maximum depth of 2.1 m. The lake floor is silted though the margins are stony. Despite its proximity to the sea, the salinity of the water is low. There is little marginal wetland vegetation. Dry grassland on shingle west of the lake has been partly improved for a pitch and putt course. The surrounding land is low lying and largely used for sheep grazing.

4.2 Quality and importance

Although small, this lake is an important example of an oligotrophic-mesotrophic system, situated directly on the Atlantic coastline. Water quality is good. The lake has an excellent diversity of aquatic plant speices and is renowned as the only Irish site for Hydrilla verticillata, a legally protected species. The lake also has abundant Najas flexilis.
