Small valley mires situated adjacent to prehistoric field systems on the East Moors of the Peak District have been dated typologically and by radiocarbon dating to the second millennium BC. These have been used as sources of evidence for environmental change, brought about primarily by prehistoric human activity. The mires have been examined using pollen, spore, charcoal and stratigraphic analyses. Regional vegetation change from the third millennium BC is illustrated in a core from a raised mire site, central to the study area. Of the small valley mire sites studied, two display similar stratigraphic sequences where clay, containing pollen types indicative of agricultural activity, is overlain by peat. Palynological evidence from the valley mire sites indicates that woodland clearance with arable activity was occurring in localized areas across the East Moors from the second millennium and through the first millennium Be. Evidence from a core taken through one of the stone boundaries in a cairnfield complex above the valley mire site at Stoke Flat suggests that the fields and boundaries were associated with this agricultural activity. Radiocarbon dating has indicated that at the valley mire sites, peat accumulation started with the decline of evidence of agricultural activity at the end of the first millennium Be. Although local conditions vary at each site, there is evidence that agricultural activity in the vicinity of the field systems occurred through the first millennium Be, towards the end of which evidence of agricultural activity declined and moorland species became established. Following widescale woodland decline at the end of the first millennium Be, evidence suggests that regeneration was prevented by increased grazing pressures, climatic change, increased rates of soil deterioration and the possible abandonment of former woodland management practices.
