The Tilia decline: vegetation change in lowland Britain during the mid and late Holocene

摘要: Pollen data indicate Tilia was an important component of the primary woodland cover many lowland areas in northern and central Europe. High values recorded mid-Holocene pollen diagrams are generally followed by well-defined declines. In this study palynological, spatial temporal trends associated with declines at sites from Britain assessed to evaluate nature relative importance processes responsible. Processes primarily related depositional environment (paludification, marine inundation, breaks sedimentation) percentage representation play dominant role 44% 164 included study. Anthropogenic activity can account for remainder. rarely recovers low after anthropogenic declines, suggesting such have potential elucidate patterns destruction across Britain. Other than Ulmus decline event, few been reliably dated prior c. 5000 cal. BP. largely disappeared calcareous loamy soils as a result clearance period 5000–3000 BP (Late Neolithic Late Bronze Age). Between 3000 2500 link between climate change. Later concentrated on sandier lithologies often heathland formation. The scarcity 2000 is likely be exhaustion woodland.
