116
species with a foliose type of thallus. The species Lepraria aeruginosa and
Xanthoparmelia somloënsis had the lowest frequency (6.67%).
The species of vascular plants on which lichens were found were mostly Acer
campestre L., Cornus mas L., Juglans regia L., Malus domestica Borkh., Robinia
pseudoacacia L., and Tilia platyphyllos Scop.
By processing the obtained data, IAP values were calculated, which varied from
10 to 28. IHI values ranged from 15, as calculated in points 12 and 13, to 36 as calculated in investigated points 3 and 7 (Table 4.2). The air quality of this urban ecosystem was analyzed for the first time using the biological-lichenological indication
of air quality in a paper published in 2019 (Ristić et al. 2019).
