Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Toninia cinereovirens faces severe threats from air pollution and acid deposition, which degrade the specific chemical conditions required for this lichen's survival. Habitat loss through urbanization and industrial development has eliminated many suitable substrates, while climate change alters the delicate moisture and temperature regimes this species depends upon.
Key Facts
Habitat & Distribution
This crustose lichen grows on calcareous rocks, concrete walls, and limestone substrates in urban and semi-urban environments. It typically occurs in areas with specific pH conditions and requires particular moisture regimes found in temperate regions.
