Pertusaria flavicans

Unknown

Overview

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

Pertusaria flavicans faces severe decline due to air pollution, particularly sulfur dioxide and nitrogen compounds that alter bark chemistry and reduce suitable substrate for this epiphytic lichen. Urban expansion and industrial development have eliminated many of its traditional host trees, while climate change is shifting precipitation patterns that affect the humid conditions this species requires for reproduction and growth.

Threat summary

Habitat

This crustose lichen grows exclusively on the bark of mature deciduous trees, particularly favoring oak and beech species in humid temperate forests. It requires stable microclimatic conditions with consistent moisture levels and clean air quality to establish and maintain viable populations.
