Overview

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

Orange-fruited Elm-lichen faces severe threats from air pollution and habitat degradation, which compromise the specific atmospheric conditions required for this sensitive epiphytic species. Urban expansion and industrial emissions have significantly reduced suitable habitat, while climate change alters precipitation patterns and temperature regimes critical for lichen survival.

Threat summary

Habitat

This epiphytic lichen grows on the bark of mature elm trees and other deciduous trees in temperate forests, particularly favoring areas with high humidity and clean air conditions. It typically occurs in old-growth or semi-natural woodland environments where atmospheric pollution levels remain relatively low.
