Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Buellia elegans faces severe threats from air pollution and acid rain, which directly damage its sensitive lichen thalli and disrupt the symbiotic relationship between fungal and algal components. Urban development and habitat destruction have eliminated many suitable substrates, while climate change alters the specific microclimate conditions this species requires for survival.
Key Facts
Habitat & Distribution
This crustose lichen grows on the bark of deciduous trees, particularly in old-growth forests and mature woodland environments with stable humidity and minimal air pollution. It requires specific bark chemistry and microclimate conditions found on aged tree trunks in undisturbed forest ecosystems.
