Cors y Gorddinan National Nature Reserve

Cors y Gorddinan National Nature Reserve is located near Llandrindod Wells in Powys, mid-Wales. It protects one of the finest examples of calcareous fen in the United Kingdom, a rare wetland habitat formed on base-rich groundwater. This waterlogged site supports an exceptional variety of fen plant species, including rare orchids, sedges, and mosses. The reserve's peat and base-rich conditions create an ecological environment that sustains unique invertebrate populations, amphibians, and birdlife, such as snipe and reed buntings. Historically shaped by traditional grazing and drainage management, Cors y Gorddinan retains a mosaic of fen, wet grassland, and open water features. Visitors are drawn to its tranquil setting and botanical richness, with boardwalks and marked paths allowing safe exploration through the fragile wetlands. Ongoing conservation efforts focus on maintaining hydrological balance and controlling invasive species to preserve the fen's biodiversity. The site offers excellent opportunities for plant identification, bird watching, and quiet reflective walks in a sensitive landscape. Educational signage and occasional guided walks help visitors understand the significance of this rare habitat. Its proximity to the surrounding Radnorshire Hills adds scenic variety for outdoor recreation. Cors y Gorddinan represents an important refuge for fen specialists and serves as a vital living laboratory for ecological research and conservation in Wales.
