The results of a study carried out to assess current environmental quality by the diversity of epiphytic lichens in the urban area of Turin (N Italy), and comparison with historical data spanning over a period of 200 years, are presented. Lichen assemblages over different time periods are related to changes in environmental conditions and the present situation is improving, as shown by increased numbers of both species and thalli in the city. Today, NOx and total suspended particles are the main air pollutants affecting lichen diversity.

Abstract
The results of a study carried out to assess current environmental quality by the diversity of epiphytic lichens in the urban area of Turin (N Italy), and comparison with historical data spanning over a period of 200 years, are presented. Lichen assemblages over different time periods are related to changes in environmental conditions and the present situation is improving, as shown by increased numbers of both species and thalli in the city.
