Large open agricultural units created for highly mechanised arable production by the removal of earlier internal boundaries between 1983 and 1999. The earlier boundaries were morphologically characteristic of the surveyed enclosures of the later 18th and earlier 19th centuries, although some displayed the irregularity associated with earlier piecemeal enclosures. The small tract of woodland 'Calf Croft' within this area probably represents one of these earlier enclosures. The straight edged 'Field Plantation' dates to the period 1851-1891. Invisible legibility of earlier enclosed landscapes due to the lack of boundaries.
