Pollen Monitoring Program (PMP)


12th International meeting POLLEN MONITORING PROGRAMME Riga, Latvia August 20th-23rd, 2019. First circular in Riga (pdf), (doc).

Pollen Monitoring Programme facilitating quantitative estimates of past vegetation and climate
The goal of the PMP is to investigate modern pollen deposition to gain insights on the pollen vegetation relationship and factors influencing production dispersal and deposition. This is often carried out by means of pollen traps providing absolute estimates of pollen deposition from different environments. Surface samples from lakes, moss cushions and soil litter are analysed for different purposes including estimating relative pollen production, taphonomy as well as for characterizing different vegetation and land use types. All efforts aim to improve our ability of interpreting fossil pollen spectra.
The use of pollen traps enables the calculation of pollen accumulation rates, (not just pollen percentages), which provides a more objective basis for interpreting the local vegetation. With an accumulated database of influx values for the major tree species and the ecologically significant shrub and herb species of Europe, the interpretation of pollen diagrams could be much more precise, particularly for those periods or situations where there is a change from unforested to forested conditions or vice versa. Guidelines for vegetation mapping can be found here.
