About Cleddau Estuary Site of Special Scientific Interest

The Cleddau Estuary SSSI is a vital coastal habitat in southwest Wales, known for its rich biodiversity and outstanding birdlife, offering excellent opportunities for wildlife observation and nature study.

Wilderness Landscape & Natural Heritage

The Cleddau Estuary Site of Special Scientific Interest (SSSI) is located in Pembrokeshire, Wales, encompassing the estuarine waters and mudflats where the Eastern and Western Cleddau rivers meet. This estuarine environment features extensive intertidal habitats, including saltmarshes, mudflats, and tidal creeks, providing crucial feeding and nesting grounds for a wide variety of bird species as well as supporting diverse marine and plant life. The estuary plays a significant ecological role as part of the Pembrokeshire Coast, balancing freshwater inflows with tidal surge from Milford Haven waterway. Historically, the area has been relatively undisturbed by development, preserving its important wildlife habitats. It is an essential site for overwintering wildfowl and waders, notably species such as redshank, curlew, and shelduck, contributing to the area's designation as a Special Protection Area (SPA). Birdwatchers and nature enthusiasts frequently visit to observe large flocks during migration seasons and winter months. The estuary’s quiet shorelines and accessible viewpoints make it a tranquil site for wildlife observation, photography, and environmental education. Though there are no developed recreational facilities or marked trails within the SSSI itself, visitors often explore nearby coastal paths within Pembrokeshire Coast National Park. Its proximity to local villages and towns enhances visitor access, providing both convenience and a connection to the cultural history of the region. The Cleddau Estuary remains a key area for ongoing conservation efforts to maintain habitat quality and protect vulnerable species.
