Middle-Holocene environmental change and archaeology in coastal wetlands: Further implications for our understanding of the history ofTaxuswoodland

Abstract

A radiocarbon-dated multi-proxy palaeoenvironmental record from Beckton in the Lower Thames Valley, Southern England, has permitted a detailed reconstruction of human activities and environmental change during the middle-Holocene. Peat accumulation occurred over river terrace gravels from ca. 7200 to 6600 until at least 3450–3240 cal. BP, and in the later period a trackway and platform structure provide unequivocal evidence for human exploitation of the floodplain environment during the Bronze Age. The site is unique in offering the first certain evidence of the utilisation of Taxus in the construction of a wooden prehistoric platform. Across north-west Europe during the middle-Holocene, the colonisation of Taxus on peat is well documented; at Beckton, it occurred between ca. 5220–4940 and 4410–4220 cal. BP. This research provides important insights into the former distribution of Taxus, and reasons for its expansion and decline during the Holocene, which has relevance to present-day concerns over the conservation and management of Taxus woodland. Abandonment of the site occurred in response to environmental change to wetter conditions. The study employed multi-proxy analyses, including pollen, plant and wood macrofossils, and uniquely Coleoptera; Coleopteran analysis has significant potential to enhance understandings of environmental change and human–environment interactions in coastal wetland research.

New insights into Late Devensian Lateglacial and early Holocene environmental change: Two high-resolution case studies from SE England

“…Despite a number of palaeoenvironmental records across south-east (SE) England, they are unevenly distributed and concentrated in coastal regions, especially the Kent and East Sussex coast (Kerney et al, 1980;Thorley, 1981;Waller, 1993;Waller and Marlow, 1994;Preece and Bridgland, 1998;Waller et al, 1999;Waller and Hamilton, 2000;Waller and Long, 2010), and the Solent (Scaife, 1980(Scaife, , 1987 (Figure 1). There is also a considerable bias towards records from floodplain locations, particularly along the lower reaches of the River Thames (Gibbard and Hall, 1982;Branch and Lowe, 1994;Wilkinson et al, 2000;Corcoran et al, 2011;Batchelor et al, 2012;Branch et al, 2012;Batchelor et al, 2014;Batchelor et al, 2015;Batchelor et al, 2019) and the Upper River Thames and River Kennett (Healy et al, 1992;Lewis et al, 1992;Parker and Robinson, 2003;Chisham, 2004).…”
