Plantations which were in the process of being planted by 1820. The plantations cover an area of 19th century ironstone workings some of which continued till 1836. Little of the site was levelled before the planting took place so legibility of the extractive landscape is significant. (Jones 1995, 87-8). There is placename evidence for this site prior to the mining period. Tankersley Plantation was previously known as Town Close Plantation (ibid, 88) and this along with Twelve Lands Plantation suggests this was an area of open fields in the medieval period (Hey 1975, 111).
