The Medmerry Managed Realignment Site is a pioneering coastal habitat restoration and flood defense project on England’s south coast, offering a haven for wildlife and space for outdoor exploration along the Sussex coastline.
Located near Selsey in West Sussex, England, the Medmerry Managed Realignment Site is one of the largest coastal realignment projects in Europe, designed to provide sustainable flood protection through the restoration of natural saltmarsh habitats. Spanning approximately 350 hectares, the site was established by intentionally breaching old sea defenses to allow tidal waters to inundate the farmland behind, creating a dynamic and extensive saltmarsh environment. This innovative approach not only reduces flood risk for surrounding communities but also enhances biodiversity by creating rich intertidal ecosystems that support numerous bird species, fish, and invertebrates. The area has quickly become a key location for birdwatching, with species such as avocets, lapwings, and various waders frequently observed. Accessible via a network of flat, gravel footpaths and wildlife hides, visitors can enjoy walking, wildlife photography, and education on coastal processes. The site is managed by the RSPB and the Environment Agency, with habitat management practices aimed at maintaining both flood defenses and natural habitats. Medmerry’s combination of ecological value, flood management innovation, and public access make it an important destination for nature enthusiasts and outdoor recreation seekers. Nearby landmarks include Selsey Bill and Chichester Harbour, providing additional opportunities for coastal walks and water-based activities.
