Ramalina protensa
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Ramalina protensa faces severe decline due to air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical composition of its substrate and disrupt its photosynthetic processes. Urban development and industrial activities have eliminated much of its suitable habitat, while climate change creates increasingly unsuitable microclimatic conditions for this pollution-sensitive lichen species.
Habitat
This epiphytic lichen grows on the bark of deciduous trees, particularly in areas with clean air and stable microclimatic conditions. It typically occurs in mature woodlands, old-growth forests, and historically in urban parks before pollution levels became prohibitive.
