Air quality improvement near a coal-fired power plant led to recolonization of Parmelia caperata (L.) Ach. in a pollution-induced void area. Recolonization was first observed about four years after pollution abatement. Least-affected sites, i.e. near the edge of the original void, were first to recover while most-affected sites were slowest to recover. After eight years of improved air quality, the distribution of P. caperata has returned to near normal. Lichen bio-monitoring is useful not only to detect the effects of poor air quality but to document air quality improvement as well.
