Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Strylavgelésopp faces severe threats from air pollution and acid rain, which degrade the air quality essential for this epiphytic lichen's survival. Climate change is altering precipitation patterns and temperature regimes, disrupting the delicate moisture balance required by this species. Habitat loss through deforestation and urban development continues to eliminate suitable host trees and forest ecosystems.
Key Facts
Habitat & Distribution
This epiphytic lichen grows exclusively on the bark and branches of Usnea lichens in old-growth coniferous and mixed forests. It requires humid, stable microclimates with consistent moisture levels and clean air quality, typically found in undisturbed forest ecosystems.
