Radnor Forest SSSI is a distinctive upland area offering diverse habitats and rich geological features, popular for nature study, hiking, and wildlife observation.
Radnor Forest Site of Special Scientific Interest (SSSI) is an upland area located in Powys, mid-Wales, characterized by a complex geological and ecological landscape. Contrary to its name, Radnor Forest is more of a rugged moorland and hill range rather than a dense woodland, featuring hills such as Black Mixen and Rhos Fawr rising to around 660 meters. Its geology is notable for a variety of sedimentary and volcanic rock formations, including Cambrian and Ordovician strata, which provide important insights into the region's ancient environments.
Ecologically, Radnor Forest hosts a mix of upland heath, acid grassland, and scattered broadleaved woodland. These habitats support a range of rare and localized plant species, including heath bedstraw and bilberry, alongside significant bird populations such as red kite, merlin, and skylark. The area is also important for its breeding upland birds and supports populations of flora and fauna adapted to acidic soils.
Historically, the area has been used for grazing and small-scale quarrying. Radnor Forest offers visitors opportunities for walking, birdwatching, and studying geology. Trails cross the moorland providing access to panoramic views across the Welsh countryside and into England. Key landmarks include summit tors and notable rock outcrops, as well as the remnants of ancient boundary markers.
Due to its ecological and geological importance, Radnor Forest is managed with the aim of conserving habitat diversity and protecting species. The SSSI designation helps safeguard this landscape from unsuitable development and promotes sustainable outdoor recreation that respects the natural environment.
