Abstract:
A major focus of palaeoecological research has been to reconstruct the vegetation history of Britain and examine the impact of humans and climatic variability on the landscape. Most studies undertaken have concentrated on the prehistoric period and less attention has been given to changes occurring in the historical period. This project therefore aims partially to redress this imbalance by presenting the findings of two palaeoenvironmental reconstructions from lake deposits in the English Midlands during the historical and archaeological periods. Palaeoenvironmental changes as inferred from pollen and mineral magnetic signatures preserved in lake sediments of two diverse lowland catchments (Kyre Pool, Worcestershire and Aqualate Mere, Staffordshire) have been placed within a rigid chronological framework usmg combinations of Radiocarbon, Spheroidal Carbonaceous Particle, profiles, Lead-210 and Caesium-137. Key periods of vegetation change have been successfully correlated with archival and archaeological records of land-use change; including the impacts of Romanisation on the landscape, agricultural changes occurring during the Medieval period. Additionally more catchment specific alterations such as Nineteenth Century landscaping and plantation of woodlands are identified and correlated with archival sources. Attempts to detect the short-term regional impact of the Laki Fissure eruption of A.D.l783 was trialled at Kyre Pool with limited success: the eruption could be stratigraphically constrained but no impact in the pollen diagram could be discerned. Findings of ,an assessment of the taphonomic processes operating in lake systems highlight the effects of surrounding vegetation in modifying the atmospheric component of pollen deposited into lakes. A comparison between sediment source changes and the preserved pollen assemblage. highlights a possible relationship between the two. Changes within the pollen record occur alongside sediment sources changes. The taphonomic process of both hydrological and atmospheric pathways has implications for preserved pollen assemblages and interpretations based upon them.
