Bactrospora dryina
Local name: stor sönderfallslav
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Bactrospora dryina faces severe decline due to air pollution, particularly nitrogen deposition and sulfur compounds that alter bark chemistry and disrupt the delicate chemical balance required for lichen survival. Old-growth forest fragmentation eliminates the mature deciduous trees with suitable bark characteristics that this species requires. Climate change compounds these pressures 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 oak and beech, in old-growth and semi-natural forests. It requires trees with specific bark chemistry and texture, typically found in undisturbed woodland environments with stable microclimatic conditions.
