Overview

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

Lecanora confusa faces severe decline due to air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical composition of its bark substrates. Urban development and intensive forestry practices have eliminated many of its preferred old-growth deciduous trees, while climate change is shifting suitable habitat zones faster than this slow-growing lichen can disperse to new locations.

Threat summary

Habitat

This crustose lichen grows exclusively on the bark of mature deciduous trees, particularly oak and beech, in old-growth and semi-natural forests. It requires trees with specific bark pH levels and is highly sensitive to air quality, thriving only in areas with minimal atmospheric pollution.
