Wetland

There are many important wetland (flowing and standing water) areas within the borough. The most important and well known is the River Thames, of which there are tidal and non-tidal sections in the borough.

Other watercourses include the River Crane, Duke of Northumberland River, Longford River and Beverley Brook, which support an array of flora and fauna such as the water vole. These wetland areas provide ideal habitats for many species, for example Leg O’Mutton reservoir and London Wetland Centre are havens for waterfowl and Stain Hill reservoir is the only known site in London that supports the nationally scarce tower mustard (Arabis glabra).
