Liden prikvortelav

Pertusaria pupillaris

Unknown

Overview

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

Pertusaria pupillaris faces severe decline due to air pollution, particularly nitrogen deposition and sulfur compounds that alter bark chemistry and disrupt lichen symbiosis. Habitat fragmentation from urban development and intensive forestry practices has reduced suitable old-growth forest patches. Climate change compounds these pressures by altering moisture regimes essential for this slow-growing crustose lichen's survival.

Threat summary

Habitat

This crustose lichen grows on the bark of mature deciduous trees, particularly in old-growth and semi-natural forests with stable microclimates. It requires trees with neutral to slightly basic bark pH and benefits from areas with consistent humidity and limited air pollution exposure.
