A pilot study on the pollen representation of mountain valley vegetation in the central Alps

The relative pollen productivity (RPP) of Pinus cembra, Larix, Picea, Gramineae, and Cyperaceae was estimated for the Upper Engadine area, an inner-alpine sub-continental valley in SE Switzerland lying above 1800 m a.s.l. The influx of pollen originating from lowlands was assumed constant between the investigated sites and could thus be used to establish relative pollen accumulation rates (rPAR) as a basis for further calculations. Wind above the canopy was assumed as the major mode of pollen transport and the effect of different wind speeds was tested. In order to evaluate the results pollen percentage values were simulated and compared with the empirical data. The method is sufficiently accurate for evaluation of spatially-explicit vegetation models, although the low number of sites eludes robust statistical testing.
