Quantification of past plant abundances based on the R-value model: Exemplified by an impact assessment of pre-historic iron production and summer farming in Budalen, central Norway

Abstract: Quantification of vegetation cover based on fossil pollen assemblages is valuable for proper assessment of past landscape dynamics. In the present investigation, the past vegetation cover around a pre-historic iron production site in the Budalen valley in central Norway was quantified using direction of vegetation change models. A set of fixed rules based on normal succession, the present vegetation and the 'intuitively' interpreted fossil pollen record was used to model spatially explicit changes in the veget… Show more

“…Grazing by large herbivores, associated with herding practices, can have long-term effects on vegetation by reducing cover and inhibiting the expansion of woody plants (27)(28)(29). In line with these effects, the gradual abandonment of transhumance activities in parts of northern Fennoscandia has resulted in the upward expansion of birch forest (30,31). Anthropogenic legacies on arctic ecosystems have so far received little attention as a contributory factor to help explain variable rates of shrubification and the apparent disequilibrium of woody species to climate.…”

“…Gaillard et al, 2010;Nielsen and Odgaard, 2010;Mazier et al, 2012;Nielsen et al, 2012;Sjögren et al, 2014). For such applications an understanding of the pollen-vegetation relationship is crucial, and the topic has attracted a substantial amount of research (e.g.…”

“…The alternative is a more indirect approach, where the base of the reconstruction is a vegetation model rather than the palaeodata itself (e.g. Gaillard et al, 2008Gaillard et al, , 2010Sjögren et al, 2014). In the latter approach, the pollen data can be used to validate and/or evaluate the model, but it is also possible to let the proxy data determine model parameter values and thus truly provide a model-based quantitative vegetation reconstruction.…”
