“…Moss samples were used because of their known suitability as pollen traps and their frequent occurrence in the area. Furthermore, their pollen content is an average pollen assemblage of several years, as it occurs in sediments, and provide a good record of local vegetation (Räsänen et al, 2004(Räsänen et al, , 2007Wilmshurst and McGlone, 2005;Mazier et al, 2006;Lisitsyna and Hicks, 2014). In each site, two moss pollsters were taken and mixed into a single sample.…”

“…Once pollen has deposited on the ground or other surfaces, it is then subject to further processes to transfer it from the surface to within the soil, particularly by rain wash and earthworms (Faegri and Iversen 1992;Davidson et al 1999). Although soil samples contain more than one season's pollen, observational studies often use moss pollsters where the type of accumulation seen in soil is absent, or Tauber traps which are less affected by soil processes such as faunal and fungal action (Lisitsyna and Hicks 2014).…”

“…Mosses are generally assumed to preserve and average several years of pollen rain (e.g. Andersen, 1970;Mulder and Janssen, 1999;Lisitsyna and Hicks 2014), although some studies indicate that they represent little more than a single growing season (Räsänen et al, 2004;Pardoe et al, 2010;Farrell et al, 2016), whereas sediment surface samples may represent ≥10 years of accumulation, although current understanding of the temporal properties of natural pollen traps is based on limited data.…”

Thick deposits of peat derived from fen environments accumulated in the coastal lowland areas adjacent to the North Sea during the middle and late Holocene. These sediments are frequently used in pollen-based reconstructions of in situ and more distant vegetation. However, discriminating between wetland and dry land originating pollen signals, and between the potential fen communities present in the wetland, is complex. In this study, a suite of analytical approaches are used to explore the pollen signal of modern fen communities and compare them against Holocene pollen assemblages. At two sites in eastern England, Woodwalton Fen and Upton Broad, vegetation composition was recorded around a series of moss polster sampling points. The communities investigated included herbaceous fen communities under different cutting regimes, a grazed area, glades, and woodland with canopies dominated by Alnus glutinosa and Betula. Cluster analysis is used to provide an overview of, and compare the structure within, the datasets consisting of the vegetation, the vegetation converted to palynological equivalents, and the pollen data. It is demonstrated that any loss of taxonomic precision in pollen identifications does not pose particular problems when attempting to identify fen communities, including tall-herbaceous vegetation, in the pollen record. Indices of Association imply pollen presence can be interpreted as indicating the local presence for some taxa, though few of these are confined to a particular community. Herbaceous fen vegetation subject to different management regimes are, however, shown to produce distinctive pollen signatures. Middle and late Holocene pollen assemblages from eastern (Fenland) and southern (Romney Marsh) England, interpreted as derived from fen vegetation, are compared against the modern pollen dataset using ordination. Most of the fossil samples plot out within or adjacent to the groupings produced by the modern samples in the ordinations. While these investigations demonstrate that modern pollen work can help improve the interpretation of Holocene assemblages they also call attention to a number of limitations including the restricted range of communities from which modern samples are currently available and the potential for non-analogous modern vegetation. The paper concludes with ideas to aid the interpretation of pollen data collected from fen peats and suggestions for future work.
