La Mare au Seigneur SSI, better known as St Ouen’s Pond in Jersey. A nature reserve containing an incredible mosaic of wetland habitats, dune grassland and the largest area of natural open water in Jersey, measuring 300m x 200m.
The first record of the pond dates back to 1309. From then up until World War II it was used by the Seigneur of St. Ouen to stock fish, such as carp, and the surrounding land was used as a hunting ground. The list of recorded birds visiting the pond include - Marsh Harrier, Bearded Tit, Cetti’s, Reed and Sedge Warblers, alongside Lapwings, Shovelers and occasionally Common Pochard are among the breeding birds. Great Bitterns winter in small numbers as well as several species of duck. A regular wintering flock of Brent Geese will sometimes be joined by other species such as Bean and Whitefronted geese. The pond area has been in the care of the National Trust for Jersey since 1975.
