Semi natural colonisation of former Rycroft Mill dam (Crossley 1989, 116 and SMR PRN 1726). This site is known to have been involved in the smelting of lead in its early history with leases of the property to Edward Ash of Tideswell between 1674 and 1674 as well as circumstantial evidence from adjacent field names 'Upper and Lower Belland' relating to land polluted with lead ore products (Crossley). By c.1800-1820 the site was owned by the Duke of Devonshire and run as a corn mill. By 1871 the mill was no longer in use. The present polygon highlights earthworks probably relating to the Dam although Crossley reports that head races can be traced in the woods from both the Ryecroft and Limb brooks; and that the outlines of buildings and traces of lead lag are visible. Fragmentary legibility of overgrown water powered site.
