About Ouse Washes Site of Special Scientific Interest (SSSI)

 

Located between the counties of Cambridgeshire and Norfolk in eastern England, the Ouse Washes Site of Special Scientific Interest (SSSI) is a large area of seasonally flooded washland formed by the River Great Ouse and its associated drainage channels. Spanning over 2,500 hectares, the area functions as an important flood storage basin that supports an extraordinary range of wetland habitats including open water, marshes, reedbeds, and grassland. The site is internationally recognized for its importance to migratory and breeding waterfowl, supporting large populations of species such as Bewick’s swan, pochard, teal, and lapwing. Extensive birdwatching hides and viewpoints allow visitors close encounters with these species during winter and migration seasons. The Ouse Washes also have cultural and historical significance, as the washland has been carefully managed for centuries using traditional drainage systems and flood defense structures to balance agricultural use with wildlife conservation. While primarily valued for its ecological importance, the area attracts nature photographers, casual walkers, and educational groups. Public footpaths run along the dykes, providing accessible routes to experience the serene floodplain landscape. Seasonal flooding creates dynamic outdoor conditions, transforming the area into a vibrant wetland playground that changes throughout the year. The proximity to nearby towns offers convenient access without compromising the site's natural tranquility.
