Agonimia tristicula
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Agonimia tristicula faces significant pressure from air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemistry of its bark substrates. Urban development and intensive forestry practices have reduced the availability of suitable old-growth deciduous trees with the specific bark pH and texture requirements this lichen needs. Climate change compounds these threats by altering precipitation patterns and increasing temperature stress on both the lichen and its host trees.
Habitat
This crustose lichen grows exclusively on the bark of mature deciduous trees, particularly favoring species with smooth to slightly rough bark such as beech, oak, and maple in humid forest environments. It requires specific microclimate conditions with consistent moisture levels and is typically found in well-established woodland areas with minimal air pollution.
