Potteric Carr is a wetwood environment currently managed as a nature reserve. The original pattern of enclosures was probably created by the massive drainage programme of Vermuyden in the 17th century. Prior to this the land was probably wet and marshy meadows. By the late 1930s the enclosures are starting to return to a more open marshy environment partly brought on by the construction of railway lines through the site. Legibility of the wet wood prior to drainage is partial as the landscape is, in part, reconstructed.
