Abstract

In 1987/89 the industrial area north of Ghent (Eastern Flanders, Belgium) was investigated for corticolous and saxicolous lichens. The data were compared with each other and with the original data on corticolous lichens sampled by ISERENTANT and MARGOT in 1963 in the same area. SO[2]-emission data were compared with the occurrence of saxicolous lichens. There is a general decline in the number of corticolous lichens per site since 1963 in spite of a decline in air pollution (SO[2]-levels). Saxicolous species penetrate strongly into the epiphyte desert. They may be used as bioindicators in heavily polluted areas. - (L'A.)
