wrattige tandpastakorst

Ochrolechia subviridis

Unknown

Overview

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

Ochrolechia subviridis faces severe decline due to air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical composition of its bark substrates. Urban expansion and industrial development have eliminated many suitable host trees, while climate change is shifting precipitation patterns that affect the delicate moisture balance this lichen requires. The species' slow growth rate and limited dispersal ability make recovery from local extinctions extremely difficult.

Threat summary

Habitat

This crustose lichen grows exclusively on the bark of mature deciduous trees, particularly favoring oak and beech species in old-growth and semi-natural forests. It requires stable microclimatic conditions with consistent humidity levels and minimal air pollution, typically found in undisturbed woodland environments.
