Christchurch Harbour Site of Special Scientific Interest (SSSI) Adventures

Christchurch Harbour Site of Special Scientific Interest (SSSI) covers the intertidal mudflats, saltmarshes, creeks, and adjoining terrestrial habitats surrounding the estuary of the River Avon and River Stour where they meet the English Channel between Dorset and Hampshire. This coastal wetland environment supports internationally important populations of birds such as dark-bellied brent geese, avocets, and oystercatchers, making it a critical wintering and feeding ground. The harbour’s combination of tidal flows and saltmarsh vegetation provides ideal conditions for a variety of invertebrates that sustain the rich avian life. The estuary includes reed beds, coastal grazing marshes, and a network of creeks that enhance its ecological complexity. Historically, the harbour has been used for fishing and boating, and while it remains a focal point for local recreation, much of the area is protected to maintain its environmental value. Visitors often enjoy walking along well-maintained coastal paths, birdwatching from hides, and visiting nearby nature reserves such as Stanpit Marsh. The area also supports rare plant species and saltmarsh communities that are vulnerable to sea level changes. Christchurch Harbour SSSI appeals to naturalists, photographers, and those seeking coastal tranquility, with accessible paths and opportunities for paddle sports in designated areas. The harbour and its environs serve as a prime example of dynamic coastal wetland habitat in southern England, highlighting the balance between conservation and community recreation.
