Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Thalloidima candidum faces severe threats from habitat loss due to deforestation and urban development, which has fragmented its remaining populations. Climate change is altering the specific microhabitat conditions this lichen requires, while air pollution from industrial activities is degrading the air quality essential for its survival.
Key Facts
Habitat & Distribution
This crustose lichen species occurs on bark of mature deciduous trees in old-growth and semi-natural forests, particularly favoring oak and beech trees in humid, shaded environments. It requires stable microclimatic conditions with high air humidity and low levels of atmospheric pollution.
