The aim of this paper is to determine the flora of lichens in the educational area of Lapjak path in the Papuk Nature Park depending on the different substrates they inhabit and evaluate ecological characteristics according to inidcator values. Exceptional diversity of geological substrates, forest phytocenosis and the distance from industrial pollution of Papuk Nature Park is also reflected in the educational area of the Lapjak path which is favorable to a large number of lichen species. During the study, 42 species were recorded and classified in 16 families and 9 oredrs of lichenized fungi. Depending on substrate they grow, 23 species of epiphytic lichens were found on trees and bushes, 16 epilithic on rocks and 3 terricolous on soil. The largest numbers of epiphytic species (12) were found on the species Fraxinus ornus and Quercus pubescens (7) with the highest concentrations around the Old Town site. Largest number of epilithic and terricolous lichens were found on Tauber's rocks. By analyzing of life forms, it was found that 45 % species of the investigated area belongs to foliose, 31 % to crustose, and 24 % to fruticose lichens. According to the indicator values the air quality was rated in the category: moderately polluted. Researches in this and other areas are important because of the monitoring diversity and change of lichen flora, conservation status of forest ecosystems and degree of air pollution
