About the site
Calshot Marshes is an area of mudflats and saltmarsh at the southern end of Southampton Water. It forms part of the Hythe to Calshot Site of Special Scientific Interest (SSSI) because of its nationally important numbers of migratory and over-wintering waders and wildfowl.
Near Calshot Activities Centre
The SSSI regularly supports more than 1% of the national winter populations of Wigeon, Teal, Ringed Plover, Grey Plover, Black-tailed Godwit, Redshank and Dunlin. During the winter months it also has a significant population of Dark Bellied Brent Geese and is considered to be of national significance to each of these species.
The numbers of some other species, Great Crested Grebe, Gadwall and Shoveler, often approach nationally important population levels. Total numbers of all waterfowl regularly exceed 10,000 in winter.
This protected area is crucial because of the immense industrial pressures that surround it.
