Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Skånsk porina faces severe threats from air pollution and acid rain, which degrade the specific bark chemistry required for this lichen's survival. Habitat loss through urbanization and intensive forestry practices in southern Sweden has eliminated many suitable host trees, while climate change alters the delicate moisture and temperature conditions this species requires.
Key Facts
Habitat & Distribution
This lichen species grows on the bark of deciduous trees, particularly in old-growth and semi-natural woodlands with stable microclimatic conditions. It requires trees with specific bark chemistry and texture, typically found in undisturbed forest environments with consistent humidity levels.
