Other Site Characteristics

Lough Nageage is situated to the east of Lough Derg, approx. 5km north-east of Pettigo, in Co. Donegal. This site contains three lakes - two of which support populations of the White-clawed Crayfish Austropotambius pallipes. The lakes lie in a basin, surrounded by gently sloping ground. The bed rock of the lakes comprise lower avonian shales and sandstones. The soil are predominantly thin peats on the sloping ground, with a greater depth of peat on flatter areas. Wet heath accounts for 60% of the site, although 40% of this area has recently been afforested (within the last 2-4 years). A small amount of blanket bog and scrub are also present. Wet grassland occurs on lands which have some mineral influence. Improved pasture also occurs.

4.2 Quality and importance

This site holds important populations of Austropotambius pallipes. The most recent records of this species at this site were recorded in 1998 (J. Reynolds). Abundant populations were noted to occur in two of the lakes in the site. The altitude of these two lakes is worthy of comment, as the Crayfish rarely occur at altitudes above 150m. Lough Nageage is 165m and Lough Veenagreane lies at an altitude of 181.5m. The site also represents one of the most northerly locations for the crayfish in Ireland. Ireland is thought to hold some of the best european stocks of this species, under least threat from external factors.
