Site description (baseline)
A large area of relatively intact blanket bog in north-west County Mayo, bounded by Bangor to the north, Mullranny in the south-west and Lough Feeagh to the east. The site is one of the best examples of an Atlantic blanket-bog system in Europe and supports a diversity of other habitats, including upland grassland, mountainous terrain, lakes and rivers. Sheep graze the area.

Key biodiversity
This site was designated as a Special Protection Area based on its high number of wintering Anser albifrons flavirostris (146 birds, 1994), together with breeding Pluvialis apricaria, both of which are Annex I species under the EC Birds Directive.

A 2002 survey of breeding Falco peregrinus found 2 pairs within the site, and another pair in the vicinity of the site.
