Abstract
This paper describes a pollen survey from Turin based on 25 taxa of interest. The survey took place between 1981 to 1988 recording pollen types and amounts. Pollen was collected using a Hirst spore trap. A pollen calendar was constructed using 10 day means: aerosporological data were then compared to the urban vegetation and flora. Pollen distribution was analysed in relation to temperature, calculated as the taxon's yearly specific temperature sum. The situation in Turin was then compared to other central European and Mediterranean stations: results were found to be more comparable with the former.
