Melanohalea exasperata

Local name: Vortet skållav

Unknown

Overview

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

Melanohalea exasperata faces severe decline due to air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical balance of its substrate. Urban expansion and industrial development have eliminated many suitable habitats, while climate change is shifting precipitation patterns that affect the moisture regimes this lichen requires for photosynthesis and reproduction.

Threat summary

Habitat

This lichen species typically grows on the bark of deciduous trees in temperate forests and woodland edges, particularly favoring areas with moderate humidity and clean air conditions.
