Abstract
The patterns of pollen deposition in the upper layers of the soil and in biological traps (mosses and lichens) in relation to the widespread and well known vegetational types of the Alps is investigated. The communities studied are beach woods, pine woods (Pinus cembra, P. sylveslris) and alpine pastures. Quantitative correlations between the pollen spectra and the vegetation have been calculated and over, under and equi-represented species delimited. Since representativity differs, in some cases, from that recorded in the literature it is suggested that it would be useful to continue the study in order to improve our understanding of actual pollen deposition and, as a consequence, of the interpretation of fossil pollen data.
