Abstract

Abstract This study showed that NH 3 emitted from geothermal power plants affects the surrounding epiphytic lichen vegetation and diversity, confounding the interpretation of lichen diversity counts in terms of air pollution by H 2S. The presence of nitrophytic lichen species around geothermal installations, determined by NH 3, caused relatively high diversity values that were not related with the levels of air pollution by H 2S. It is recommended that in the presence of NH 3 emission, nitrophytic species are excluded from the calculation of lichen diversity values.
