Bryoindication of the general state of atmosphere in an urban ecosystem: The example of the city of Bryansk

Bryoindication mapping was performed on the basis of synthetic poleotolerance indices for 147 test plots in the city of Bryansk (the southwestern nonchernozem zone of Russia). Individual poleotolerance coefficients of bryophytes were determined. Changes in the state of the atmosphere in the city ecosystem over 12 years were analyzed.
