[Correlation of the pollen content of the air with the geography and vegetation in a mountain range and its allergologic importance].

For several years pollen traps have been installed at different sites in the Inn valley/Tyrol. Even within short distances significant differences in the pollen content of the air in respect to amount and time do occur. The pollen maxima differ even up to 6 weeks during subsequent years. The mean values of the maxima of the same species differ up to 12 days at the different sites. In mountain areas with small-scale vegetation patterns and climatic differences it is therefore necessary to set up a dense network of pollen traps especially in respect to the medical use of the results.
