Sites of Lobaria pulmonaria reported from the nemoral zone of the Swedish provinces Skåne and Blekinge since 1990 were revisited. At each locality, the habitat ecology and lichen viability were investigated. A substantial decline was noted, particularly in Skåne, as L. pulmonaria was found at only 24 sites, 22 of which were forests and two were wooded meadows. The commonest habitats for L. pulmonaria were Tilio-Acerion forests and species-poor, oligotrophic beech forests, and the commonest substrates were trunks of Acer platanoides and Fagus sylvatica, followed by Quercus robur. The inhabited trees grew often in the upper part of steep slopes or rock faces, either on rocky or boulder-rich, meso- to oligotrophic soils. Lobaria pulmonaria showed a preference for locally cool climates. It had survived at sites offering a stable environment in terms of light, moisture and temperature, with minor influence of air pollution, agriculture and forestry practices.
