Micarea adnata

Unknown

Overview

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

Micarea adnata faces significant pressure from air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemistry of its bark substrates. Urban development and forest management practices that favor younger tree stands reduce the availability of mature trees with suitable bark characteristics. Climate change compounds these threats by altering precipitation patterns and increasing the frequency of extreme weather events that can damage host trees.

Threat summary

Habitat

This crustose lichen grows exclusively on the smooth bark of deciduous trees, particularly favoring mature specimens in old-growth and semi-natural forests. It requires specific microclimate conditions with moderate humidity and limited direct sunlight, typically found in forest interiors and sheltered woodland edges.
