Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Mörk lundlav faces severe threats from air pollution, particularly nitrogen deposition and sulfur compounds, which alter the chemical composition of its substrate and disrupt its growth. Habitat loss through deforestation and urbanization has eliminated many suitable old-growth forest sites, while climate change is shifting temperature and humidity patterns beyond the species' tolerance range.
Key Facts
Habitat & Distribution
Mörk lundlav grows on the bark of deciduous trees, particularly in old-growth and mature forests with high humidity and stable microclimatic conditions. It typically occurs in shaded woodland environments with minimal air pollution and established forest ecosystems.
