Site description
Lough Derg is a large lake, situated approximately 6 km north of Pettigo in County Donegal. The lake is naturally nutrient-poor (oligotrophic). It is surrounded by extensive conifer plantations; good examples of wetland scrub occur on the lakeshore and islands.

Key biodiversity
The site was designated as a Special Protection Area on the basis of migratory waterfowl populations. An island within the lough is regularly used as a winter feeding site by small numbers of Anser albifrons flavirostris. The main flock uses site 027, immediately east of Lough Derg and separated by conifer plantations. There is also a nationally important breeding colony of Larus fuscus (800 birds, 1990).
