Cliostomum leprosum
Local name: mjölig dropplav
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Mjölig dropplav faces severe decline due to air pollution, particularly nitrogen deposition and sulfur compounds that alter bark chemistry and disrupt its specialized substrate requirements. The species is highly sensitive to atmospheric changes, with populations disappearing from formerly suitable habitats as air quality degrades. Climate change compounds these pressures by altering precipitation patterns and temperature regimes that affect both the lichen and its host trees.
Habitat
This crustose lichen grows on the bark of old deciduous trees, particularly favoring smooth-barked species like beech and maple in mature forest environments. It requires stable microclimatic conditions with consistent humidity and minimal air pollution, typically found in well-preserved woodland areas.
