During the 20th century, reclaiming land from the sea - especially along Britain’s low-lying east coast - was a popular way of increasing the land available for farming. Most of Britain's inter-tidal saltmarsh has been lost in this way. Today, in the face of rising sea levels, the cost of maintaining many sea wall defences is starting exceed the value of farming goods produced from the land that the seawalls protect. A new defence against coastal flooding is urgently required. At Freiston Shore, in Lincolnshire, the sea has been allowed to breach the sea wall to re-create the original saltmarsh landscape, which acts as a natural buffer against rising sea levels by absorbing the power of the waves before they reach dry ground further inland. In the process, the saltmarsh provides a valuable inter-tidal, twice-daily coastal feeding habitat for many wading birds.
