  • 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)

3.2 Species referred to in Article 4 of Directive 2009/147/EC and listed in Annex II of Directive 92/43/EEC and site evaluation for them

  • Type: p = permanent, r = reproducing, c = concentration, w = wintering (for plant and non-migratory species use permanent)
  • Unit: i = individuals, p = pairs or other units according to the Standard list of population units and codes in accordance with Article 12 and 17 reporting (see reference portal)
  • Abundance categories (Cat.): C = common, R = rare, V = very rare, P = present - to fill if data are deficient (DD) or in addition to population size information
  • 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); VP = 'Very poor' (use this category only, if not even a rough estimation of the population size can be made, in this case the fields for population size can remain empty, but the field "Abundance categories" has to be filled in)

Other Site Characteristics

Situated approximately 0.5km from the sea to the north, this site comprises an acid, deep, stony-bottomed lake with grassy, heathy cliffs to the south, blanket bog to the south-west and improved and humid grassland and scrub to the west. The margins of the lake support little emergent vegetation, however, a number of aquatic species do occur. The site includes a small rocky islet in the lake with gull and tern colonies. The site is underlain by quartzite.

4.2 Quality and importance

A diverse site that supports a range of rare or notable plants (Najas flexilis), birds (Falco peregrinus, Anser albifrons flavirostris, Sterno hirundo, Larus ridibundus), mammals (Lutra lutra) and fish (Salvelinus alpinus, Salmo trutta). Sessiagh Lough itself contains a number of species characteristic of oligotrophic lakes, but also supports several species more usually associated with mesotrophic situations; its trophic status appears to be in a state of flux.
