About Radnor Forest SSSI (Site of Special Scientific Interest)

 

Radnor Forest SSSI is a distinctive upland area located in Mid Wales, predominantly within Powys. It covers a mixture of rocky outcrops, heather moorland, and fragmented woodland, lying within a region characterized by its isolated hills and panoramic views over the Welsh Borders. The site's geological significance stems from its Precambrian and Ordovician rock formations, including prominent sandstone and limestone exposures, which have influenced the area's topography and habitats. Ecologically, it is valued for its heathland, acid grasslands, and calcareous flushes supporting populations of rare plants such as the creeping lady’s-tresses orchid and several moss and liverwort species. The area provides important nesting sites for birds including the merlin and red kite as well as habitats for invertebrates and small mammals typical of upland heath. Historically, Radnor Forest has connections to ancient hunting grounds and traditional common land rights, adding to its cultural significance. Outdoor recreation focuses on hiking through a network of footpaths that traverse its undulating terrain, rock climbing on rugged crags, and birdwatching. The region is less frequented than many other Welsh uplands, offering visitors a quiet and contemplative natural experience. Key landmarks include the summit of Black Mixen, notable for its radio transmitter mast and commanding views, and the old disused quarries that reveal the area's industrial past. The SSSI designation helps conserve the diverse habitats and protect fragile species, making the site an important asset for conservation and education.
