This polygon covers a large area of former wetlands. Removal of field boundaries, mostly in the latter part of the 20th century has created an area of agglomerated fields much in keeping with the surrounding fields, many of which have a different origin. 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. Extensive crop marks, probably of Iron Age and Romano-British field systems have been recorded. Legibility of the former landscape is partial as the field drains still exist amongst the fields.
