Melanohalea laciniatula

Local name: Småfliget skållav

Unknown

Overview

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

Småfliget skållav faces severe decline due to air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical balance of its substrate. The species is extremely sensitive to atmospheric pollutants, which disrupt its symbiotic relationship with photosynthetic algae. Habitat fragmentation and loss of suitable old-growth forest environments further compound population pressures, as this lichen requires specific microclimate conditions found in undisturbed woodland ecosystems.

Threat summary

Habitat

This foliose lichen grows on the bark of deciduous trees, particularly in old-growth and mature forests with stable microclimates. It favors areas with high humidity and clean air, typically found in undisturbed woodland environments across northern Europe.
