Overview

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

Ramalina lacera faces severe threats from air pollution and habitat degradation, as this lichen species is highly sensitive to atmospheric contaminants and changes in air quality. Urban expansion, industrial emissions, and climate change are causing widespread population declines across its range, with many historical localities now showing complete absence of this species.
