Pertusaria confundens

Unknown

Overview

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

Pertusaria confundens faces severe threats from air pollution and acid rain, which directly damage its sensitive lichen thallus and disrupt the symbiotic relationship between fungal and algal components. Urban development and industrial activities have eliminated much of its suitable habitat, particularly in areas with clean air quality essential for lichen survival. Climate change compounds these pressures by altering precipitation patterns and temperature regimes that affect both the species and its host trees.

Threat summary

Habitat

Pertusaria confundens is a crustose lichen that grows on the bark of deciduous trees, particularly in areas with high air quality and stable microclimatic conditions. It typically occurs in mature woodlands and old-growth forests where atmospheric pollution levels remain low enough to support sensitive lichen communities.

Frequently asked questions

Why is Pertusaria confundens classified as Endangered?
Pertusaria confundens is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Pertusaria confundens faces severe threats from air pollution and acid rain, which directly damage its sensitive lichen thallus and disrupt the symbiotic relationship between fungal and algal components. Urban development and industrial activities have eliminated much of its suitable habitat, particularly in areas with clean air quality essential for lichen survival. Climate change compounds these pressures by altering precipitation patterns and temperature regimes that affect both the species and its host trees.
Where does Pertusaria confundens live?
Pertusaria confundens occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Pertusaria confundens?
The main threats to Pertusaria confundens are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
