“…Based on the empirical studies, the relevant source area (RSAP; Sugita 1994Sugita , 1998 of pollen is ca. 1,500-2,000 m in similarly sized sites (Sugita et al 2010;Poska et al 2011). As the distance between the coring sites is about 450 m, the source areas of all the sediment cores partially overlap.…”

“…Poska et al (2011) discussed use of CORINE data as a basis for vegetation maps, and found that it produced similar pollen productivity estimates as using a more detailed vegetation dataset based on state forest data. There are differences in CORINE data classification across national boundaries, but there are also differences in data recorded for other purposes, such as forestry records.…”

“…Although different distance weighting methods are found to affect RPP estimates (e.g. Broström et al, 2004;Mazier et al, 2008;Bunting and Hjelle, 2010;Poska et al, 2011), little systematic empirical study has been carried out to show how these methodological choices affect estimated values of RPP, or investigate how the different models relate to pollen movement in the landscape. In the absence of such empirical evidence, the Crackles Bequest Project strategy needs to collect data in a format which can be analysed using different ring-width and weighting strategies at a future date.…”

“…In most studies to date, the pollen taxon Poaceae has been used as the reference taxon (e.g. Hjelle, 1998;Broström et al, 2004;Nielsen and Odgaard, 2004;Räsänen et al, 2007;Soepboer et al, 2007;Mazier et al, 2008;von Stedingk et al, 2008;Poska et al, 2011;Abraham and Kozáková, 2012), although since this pollen taxon can originate from a wide range of plant species, it is likely that the same pollen type represents different plant species mixtures in the different studies making inter-study comparison less reliable.…”

Collection of surrounding vegetation data will necessarily differ between the use of traps/moss polsters and lake sediments, and the methodology selected in the present paper is based on the use of surface moss samples for pollen collection.…”

Pollen dispersal and deposition models Pollen surface sample PrenticeeSugita model of pollen dispersal and deposition Remote sensing data Sutton model Vegetation data processing a b s t r a c t 1. Quantitative reconstruction of past vegetation distribution and abundance from sedimentary pollen records provides an important baseline for understanding long term ecosystem dynamics and for the calibration of earth system process models such as regional-scale climate models, widely used to predict future environmental change. Most current approaches assume that the amount of pollen produced by each vegetation type, usually expressed as a relative pollen productivity term, is constant in space and time.2. Estimates of relative pollen productivity can be extracted from extended R-value analysis (Parsons and Prentice, 1981) using comparisons between pollen assemblages deposited into sedimentary contexts, such as moss polsters, and measurements of the present day vegetation cover around the sampled location. Vegetation survey method has been shown to have a profound effect on estimates of model parameters (Bunting and Hjelle, 2010), therefore a standard method is an essential pre-requisite for testing some of the key assumptions of pollen-based reconstruction of past vegetation; such as the assumption that relative pollen productivity is effectively constant in space and time within a region or biome.3. This paper systematically reviews the assumptions and methodology underlying current models of pollen dispersal and deposition, and thereby identifies the key characteristics of an effective vegetation survey method for estimating relative pollen productivity in a range of landscape contexts.4. It then presents the methodology used in a current research project, developed during a practitioner workshop. The method selected is pragmatic, designed to be replicable by different research groups, usable in a wide range of habitats, and requiring minimum effort to collect adequate data for model calibration rather than representing some ideal or required approach. Using this common methodology will allow project members to collect multiple measurements of relative pollen productivity for major plant taxa from several northern European locations in order to test the assumption of uniformity of these values within the climatic range of the main taxa recorded in pollen records from the region.

Quantitative understanding of vegetation dynamics over timespans beyond a century remains limited. In this regard, the pollen-based reconstruction of past vegetation enables unique research opportunities by quantifying changes in plant community compositions during hundreds to thousands of years. Critically, the methodological basis for most reconstruction approaches rests upon estimates of pollen productivity and dispersal. Previous studies, however, have reached contrasting conclusions concerning these estimates, which may be perceived to challenge the applicability and reliability of pollen-based reconstruction. Here we show that conflicting estimates of pollen production and dispersal are, at least in part, artifacts of fixed assumptions of pollen dispersal and insufficient spatial resolution of vegetation data surrounding the pollencollecting lake. We implemented a Bayesian statistical model that related pollen assemblages in surface sediments of 33 small lakes (<2 ha) in the northeastern United States, with surrounding vegetation ranging from 10 1 to >10 5 m from the lake margin. Our analysis revealed three key insights. First, pollen productivity is largely conserved within taxa and across forest types. Second, when local (within a 1-km radius) vegetation abundances are not considered, pollen-source areas may be overestimated for some common taxa (Cupressaceae, Pinus, Quercus, and Tsuga). Third, pollen dispersal mechanisms may differ between local and regional scales; this is missed by pollendispersal models used in previous studies. These findings highlight the complex interactions between vegetation heterogeneity on the landscape and pollen dispersal. We suggest that, when estimating pollen productivity and dispersal, both detailed local and extended regional vegetation must be taken into account. Also, both deductive (mechanistic models) and inductive (statistical models) approaches are needed to better understand the emergent properties of pollen dispersal in heterogeneous landscapes.
