Adam BEGU of pollutants on lichen formations in different ecological niches. Later on, the same author [3] applied a quantitative method of mapping the intensity of air pollution based on lichens substrate coverage, frequency, abundance and tolerance, thus designating areas with different degree of pollution. §tefanescu & Bartók [41, 42] undertook a joint research on lichen species from the Romanian industrial region of Baia Mare by mapping the intensity of air pollution. It is well known that epilithic species have a mainly crustose structure and such species are not recommended for ecobio-indication because they remain practically indifferent to pollutants at moderate and high concentrations [32]. Recently, the bio-indicator features of lichens have become a research subject at the National Institute of Ecology. Over 80 meadow and hill forest ecosystems were studied (Fig. 1), targeting epiphytic lichen species, and bio-indicator species, in particular. Fig. 1: Forest ecosystems were studied For the first time have been described 23 species (Tab. 1). Lichen abundance, toxitolerance and diversity were studied, against air quality. The results were presented in a number of works by Begu [3, 6, 7, 8, 9, 10, 11, 12, 13].
