Slieve Beagh is a unique upland bog and blanket bog habitat straddling the border of Northern Ireland and the Republic of Ireland, offering remote wilderness appeal and important ecological diversity.
Slieve Beagh Area of Special Scientific Interest (ASSI) encompasses an upland plateau marked by expanses of blanket bog, heath, and wet grasslands. It lies across the border counties of Fermanagh in Northern Ireland and Monaghan and Tyrone in the Republic of Ireland. The landscape is notable for its gently rolling hills interspersed with bog pools and small streams, creating a mosaic of habitats important for a variety of rare plants and wildlife. This area supports one of the few remaining intact blanket bog ecosystems in Ireland, providing crucial carbon storage and biodiversity functions. Ecologically, the site is home to blanket bog species including cross-leaved heath, cloudberry, and carnivorous sundews, while birdlife features species such as hen harrier, merlin, and golden plover, making it a prime birdwatching locale. Historically, Slieve Beagh’s remote nature means few human structures or roads interrupt the natural landscape, though old peat-cutting and occasional archaeological remains hint at traditional land uses. For outdoor enthusiasts, Slieve Beagh offers peaceful hiking and wildlife observation opportunities without the crowds commonly found in more developed protected areas. Its isolation and rugged terrain make it especially appealing to those seeking solitude and quiet connection with wilderness. Being a cross-border designated conservation site, it also plays an important role in cooperative environmental stewardship. Visitors can explore peatland trails, upland heath, and discover hidden natural features, while enjoying panoramic views over the surrounding counties.
