Wallasea Wetlands

They provide winter grounds for wading birds, as well as breeding and nursery areas for aquatic wildlife, such as bass, mullet, flatfish and herring and even some types of dolphin.

In the process being termed "managed re-alignment", the seawall that protects croplands and property was re-established in more tenable positions, three miles behind the new wetlands, which will provide habitat for birds like oystercatchers, avocets and little terns, according to the press release issued at the time.

Construction was completed in 2006 and by 2011 the land had evolved into wetland, mudflats, saline lagoons and seven artificial islands, allowing the wildlife to reside on these areas.

An extension to the scheme, using 2,400 shiploads of spoil excavated from London's Crossrail tunnels, was completed in July 2015, when an additional area of land was opened to tidal flow.

The following criteria for Wallasea Wetlands has been met in accordance with this ruling: In 2005, the £7.5million project to return the island to its original salt marsh was commenced, beginning with the construction of the new sea defence wall, defining the area where the tides were permitted to flood.
