Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Sørlandsragg faces severe threats from air pollution, particularly nitrogen deposition and sulfur compounds, which dramatically alter the chemistry of its substrate and surrounding environment. Climate change is causing shifts in precipitation patterns and temperature regimes that affect the delicate moisture balance this lichen requires, while coastal development and infrastructure projects continue to destroy its specialized rocky habitats along the Norwegian coastline.
Key Facts
Habitat & Distribution
Sørlandsragg grows exclusively on siliceous rocks and coastal cliffs in maritime environments along the southern Norwegian coast, particularly in areas with specific microclimatic conditions that provide the right balance of moisture and exposure. This lichen requires clean air and stable substrate chemistry to survive in these specialized rocky coastal habitats.
