Aerobiological Biodiversity in the Metropolitan City of Rome

Pollen monitoring is a useful tool for characterizing the flora present in a territory. Exposure to pollen is closely related with the season of flowering and the period of phenology of plants. The period of pollination and the pollen dispersion in air is conditioned also by meteorological variables, latitude, height above sea level and climatic conditions of each zone. In fact, the pollen presence changes both over years and months, and over days and hours of the day. This is a preliminary study that shows the use of pollen as bioindicators of the floristic-vegetational diversity and ex-post characterization of a site.
