Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Opegrapha rupestris faces severe threats from air pollution and acid rain, which alter the chemistry of its rock substrates and directly damage lichen tissues. Habitat destruction through quarrying, construction, and urban development has eliminated many suitable rock surfaces, while climate change is shifting precipitation patterns and temperature regimes beyond the species' tolerance limits.
Key Facts
Habitat & Distribution
This crustose lichen species grows exclusively on siliceous rocks, particularly granite and sandstone outcrops, cliffs, and boulders in both natural and semi-natural environments. It typically occurs in areas with moderate to high humidity and clean air conditions, often in upland and montane regions.
