Overview

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

Pendulous Wing-moss faces severe decline due to air pollution, particularly nitrogen deposition and acid rain, which alter the chemical composition of its bark substrates. Old-growth forest destruction eliminates the mature trees with suitable bark chemistry that this epiphytic moss requires. Climate change compounds these pressures by altering humidity patterns and increasing drought stress in its montane forest habitats.

Threat summary

Habitat

This epiphytic moss grows exclusively on the bark of mature deciduous trees, particularly oak, beech, and maple, in humid old-growth and semi-natural forests. It requires specific bark chemistry conditions and high air humidity, typically found in montane and submontane forest ecosystems across temperate regions.

Frequently asked questions

Why is Pendulous Wing-moss classified as Vulnerable?
Pendulous Wing-moss is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue.
