Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Treeflute Lichen faces severe decline due to air pollution, particularly nitrogen deposition and sulfur compounds that alter bark chemistry and disrupt its delicate symbiotic relationship. Old-growth forest fragmentation eliminates the stable microclimatic conditions this species requires, while climate change intensifies drought stress that weakens both the lichen and its host trees. Urban expansion and industrial development continue to reduce suitable habitat across its limited range.

Threat summary

Habitat

Treeflute Lichen grows exclusively on the bark of mature deciduous trees in old-growth and semi-natural forests, particularly favoring oak, beech, and maple species. It requires stable humidity levels and clean air conditions found in undisturbed forest interiors with minimal human disturbance.
