Abstract: 5 figures. 2 tables. ["Lichen community parameters (species composition, species richness, total cover index, and Index of Atmospheric Purity) were correlated with 3-year mean annual SO2 levels ... in and around Indianapolis, Indiana, U.S.A. Weaker relationships were found between lichen communities and peak SO2 levels. In contrast, spatial variations in ozone peaks ... for yearly 1-hour highs averaged across three years and 3-year ozone means ... were not correlated with lichen communities."]
