Protoblastenia cyclospora
Local name: röd guldskivlav
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Protoblastenia cyclospora faces severe decline due to air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical composition of its substrate. Urban development and industrial activities have eliminated many suitable rock surfaces, while climate change affects the delicate moisture balance required for this lichen's survival. The species' extremely slow growth rate makes recovery from disturbances exceptionally difficult.
Habitat
This crustose lichen grows exclusively on calcareous rocks and concrete surfaces in urban and semi-urban environments. It requires specific pH conditions and moderate air humidity, typically found on old walls, limestone outcrops, and weathered concrete structures.
