Carmarthen Bay and Estuaries Special Area of Conservation is a protected coastal and estuarine region in southwest Wales, known for its rich biodiversity and important habitats for marine and bird life.
Carmarthen Bay and Estuaries Special Area of Conservation (SAC) covers a significant stretch of coastline and estuarine environments in southwest Wales, including the estuaries of the Rivers Tywi, Tâf, and Gwendraeth. This protected site encompasses extensive intertidal mudflats, sandflats, saltmarshes, and rocky shores which support a wide range of plant and animal species. Due to the dynamic nature of the estuarine environment, it provides critical nursery areas for fish and feeding grounds for internationally important populations of wintering and breeding birds such as oystercatchers, redshanks, and shelducks. The SAC also includes habitats for rare marine species including populations of flatfish and other estuarine fish, as well as supporting diverse invertebrate communities. Beyond its ecological significance, Carmarthen Bay’s scenic coastline offers opportunities for birdwatching, coastal walking, and watersports such as kayaking and fishing. The nearby towns and villages provide access points for exploration, and visitors appreciate the relatively tranquil natural setting combined with striking coastal views and tidal estuary landscapes. Conservation efforts focus on maintaining water quality, preventing habitat loss, and monitoring species populations, making this area important not only for nature enthusiasts but also for researchers and conservationists. The site represents a key coastal conservation area within Wales’ wider network of protected marine and estuarine territories.
