Abstract
The susceptibility of lichens to changes in the urban environment make them good indicators of the intensity of air pollution. Studies covering a number of large and small towns, mostly in Europe and some over an extended time, explored the toxic influence of air pollution on 12 species on lichens. A comparison after 18 years with the lichen flora of Lublin, Poland found the lichen population impoverished. The toxic hypothesis, which blames increased coal consumption and automobile use, is inadequate to explain the condition. The drought hypothesis, which postulates that the occurrence and distribution of individual species is the result of a complex of numerous macro- and microclimatic, edaphic, geographical, historical, and other factors, gives a uniform view of the problem and stimulates investigations of the ecology of lichens in their natural habitat as well as in towns. 40 references, 12 figures, 3 tables.
