[in German with English summary: ] With the aim of assessing the air quality in the city of Augsburg, a mapping of the epiphytic lichen vegetation was carried out in 2017 according to the VDI guideline 3957 (bioindication) and presented in an air quality map. A “low” to “moderate” air quality was determined for the investigated area. Compared to the air quality mapping results of 1985 and 2008, there are no more lichen-free areas or areas with “very low” air quality recorded. In addition to a few improvements in some city districts, air quality has deteriorated in almost half of the study area compared to the last mapping. The reason for this is the high eutrophication of the urban area. This is most visible in the change in the species spectrum. Nitrophytes are increasing strongly, while acidophytes are on the retreat. Key Words: lichen monitoring, bioindication, urban air pollution, eutrophication.
