A complicated area featuring many larger fields resulting from agricultural intensification. The polygon covers the likely area of the three medieval open fields associated with Ulley- Nether Field, North Field and Top Field. These fields are named on the Ulley enclosure award map of 1800. Nether Field is still shown just outside Ulley, although much reduced in size. The enclosure map appears to show that the fields had already been subject to some enclosure by private agreement but much of the North field and Top field were enclosed by the award. Agricultural intensification since the mid 20th century has resulted in the removal of many of the parliamentary field boundaries. Many of the remaining field boundaries consist of hedgerows along parish boundaries. These may be medieval in origin. Legibility is partial due to this.
