High on the slopes of Slieveanorra Mountain are four plots of peat bog which show different stages in the formation and erosion of peat. The Owennaglush plot is a rare example of a raised bog in which the peat is actively growing, while the Orra Bog and Slieveanorra plots show what happens when shallow blanket peat is eroded. The plant life varies from heather and deer grass in drier areas, to damp patches where sphagnum moss, sedges and cotton grass grow.
Bog asphodel, bog-bean and insect-eating sundews live on the edges of bog pools on Owennaglush. Hen harriers, merlins and red grouse have adapted to life and made their home in these upland areas.
Due to the fragile nature of the bog and the danger of deep swallow holes, visitors are asked to contact the NIEA Site manager based at County Hall Castlerock Road, Coleraine, to arrange access.Tel: 028 703 59977.
