Abstract
The lichen flora on tree trunks around a shale oil works in southern Sweden has been analyzed with regard to composition and distribution on two different occasions, in 1951/1953 and in 1967/1969. Changes in the distribution have been observed and are regarded as being due to the increase of sulfur dioxide in the atmosphere which took place in the area up to 1966, and which resulted in the substrate becoming more and more acid. The changes consist partly of the continued disappearance from the investigated area of lichens which normally grow on moderately acid to nearly neutral substrate and partly in the new colonization of the investigated area by a group of species which normally grow on acid bark. After 1966 the biggest source of pollution was removed from the area and in the summer of 1967 some signs of recovery could be already observed with regard to certain species. This recovery took the form of strong lobe growth leading to a definite difference in appearance between the central and the peripheral parts of single lichens.
