Lichens are organisms widely used as bioindicators of air quality. Due to the sensitivity of these organisms to atmospheric pollutants, in highly polluted environments, only the most resistant species predominate or even become extinct. In this work, the concentration of lichens on trees in the city of Paranaguá was evaluated to compare the air quality of the port and commercial area with the air quality of the residential region. We evaluated ninety trees distributed throughout the city, where we observed that both the concentration of lichens and the variety of species are higher in residential areas than in port areas, probably due to the better air quality in the residential area of Paranaguá.
