Megalaria pulverea

Local name: pulverädellav

Unknown

Overview

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

Megalaria pulverea faces significant pressure from air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical composition of its bark substrates. Forest fragmentation and the loss of old-growth deciduous trees reduce available habitat, while climate change may be shifting suitable conditions beyond the species' current range. The lichen's sensitivity to atmospheric pollutants makes it particularly vulnerable in industrialized regions of Europe.

Threat summary

Habitat

This crustose lichen grows primarily on the bark of mature deciduous trees, particularly oak, beech, and maple in old-growth and semi-natural forests. It favors trees with slightly acidic to neutral bark in areas with relatively clean air and stable microclimatic conditions.
