To the editors


The evidence for links between the pollen count/exposure and the onset of allergy symptoms is manifold [1, 2]. It is important for allergy sufferers to know the pollination period. Most plant species dynamically react to changes in their environment. The rise in mean global temperatures associated with climate change has a major effect on the phases of plant development. Therefore, pollination times may change over the years and necessitate an update of previous pollen calendars (PC). The most important requirements for creating current interregional PC are continuous, coordinated, and standardized monitoring of airborne pollen in a pollen monitoring network and archiving the data thus obtained.


The German Pollen Information Service Foundation (Stiftung Deutscher Polleninformationsdienst, PID) has been operating a monitoring network in Germany comprising volumetric pollen traps since 1983 [3]. To date, three PC have been published on the basis of...

We would like to thank the following two institutions for providing their pollen data: data from Cottbus and Drebkau were provided by Pulmologische Gemeinschaftspraxis U. Gereke/Dr. med. F. Schneider, Cottbus, and data from Munich by Technische Universität München, ZAUM—Zentrum Allergie und Umwelt, München.
